How To Increase Soil Microbial Activity

Soil Microbial Action

Namely, soil microbial activity that reflects microbiological processes of soil microorganisms is the potential indicator of soil quality, every bit plants rely on soil microorganisms to mineralize organic nutrients for fruit tree growth and development (Chen et al., 2003).

4.ane.3 Microbial activeness

An awareness that soil microbial activity might have a part in developing soil structure, has existed for many years. McCalla (1945) set out to promote microbial activity in a poorly structured loess soil in Nebraska, past adding crop residues and hay to the soil. The treatments improved the stability of soil aggregates which was attributed to the breakup products from microbial activeness (McCalla, 1945). Later studies accept shown that soil bacteria themselves, release binding agents that heighten soil aggregation (Aspiras et al., 1971). The leaner produce extracellular polymeric substances that are released in the form of a peripheral slime. Rashid et al. (2016) report that bacteria reside every bit private cells, micro-colonies or as biofilms in the aqueous solution within the finer pores of the soil matrix. They play a role in binding clay particles to form microaggregates (Lupwayi et al., 2001; Tisdall and Oades, 1982), and and then the ratio of leaner to fungi is college in microaggregates (20–250 μm), compared to the ratio in larger macroaggregates.

There is a perception that soil fungi play a more dominant role than leaner in developing soil structure. This arose from a serial of incubation studies (Metzger et al., 1987; Roldán et al., 1994; Tang et al., 2022) where organic amendments were added to a poorly structured soil, with bactericide and fungicide treatments. In each of these studies, the apply of the fungicide impaired the formation of soil aggregates, while the soil became aggregated with the bactericide handling. A limitation with these experiments was that they did non include plant roots and so there was no rhizosphere soil and associated carbon substrates contained in root exudates. Such a soil would provide a favorable environment for leaner and bacterial action. This view is supported by French studies where seedlings were inoculated with exopolysaccharide (EPS) producing bacterial preparations (Alami et al., 2000; Amellal et al., 1998, 1999). These studies reported increases in the aggregation in the rhizosphere soil of the seedlings subsequently 20 days of growth, when EPS-producing leaner were active in the rhizosphere.

Soil fungi play several roles in the evolution of soil construction. The hyphal network can entangle soil particles and hold them together (Peng et al., 2022; Tisdall, 1994). Hyphae can release of chemical compounds including polysaccharides and glycoprotein mucilage, which act as adhesives to concord soil particles together (Tisdall, 1991). Arbuscular mycorrhizal fungi, which are ubiquitous and course beneficial symbioses with many plants, are specially effective in the formation of soil aggregates. Tisdall and Oades (1979), attributed the improvement in aggregation with ryegrass roots in their experiments to the large numbers of arbuscular mycorrhizal hyphae that were present around the roots.

Direct prove for the beneficial furnishings of arbuscular mycorrhizal fungi come up from studies by Thomas et al. (1993) and Hallett et al. (2009). They used soil columns, split up with a fine nylon mesh, to separate the effects of roots from the furnishings of mycorrhizal hyphae. In both studies the benefits from the hyphae were quite marked and contributed significantly to the root's ability to increase soil aggregation. Similarly, in a study with perennial grass, Miller and Jastrow (1998) analyzed soil assemblage data using path analysis and found that the length of mycorrhizal hyphae in the soil was the most pregnant factor in increasing the size of water stable aggregates.

Potential of Increased Temporal Ingather Diverseness to Ameliorate Resource Use Efficiencies

Leah L.R. Renwick , ... Amélie C.Thou. Gaudin , in Agroecosystem Diversity, 2022

Labile C and Microbial Processes for N Retentivity and Mineralization

Diverse rotations also bear on soil microbial biomass and activity via changes in readily available soil C that increases N memory and mineralization. Compared to monoculture, rotations of two or more than crops have 20.7% and 26.1% higher microbial biomass C and Northward, respectively, an event that does not vary with encompass crop inclusion in the rotation or cash crop type (McDaniel et al., 2022b). Recent experimental evidence (Santonja et al., 2022; Tiemann et al., 2022) too links constitute species diversity to higher microbial functional diversity and activity and faster residue decomposition rates under water-limited weather condition, even when crop residue was of poor quality (McDaniel et al., 2022a), as well as higher action of microbial enzymes involved in SOM breakdown and Due north mineralization (Acosta-Martinez et al., 2022; Carpenter-Boggs et al., 2000; Dodor and Tabatabai, 2003; Ekenler and Tabatabai, 2002; Klose and Tabatabai, 2000; McDaniel et al., 2022a). Such changes are driven mainly by higher "active" (labile) soil C pools in more than diverse crop rotations (McDaniel and Grandy, 2022; Tiemann et al., 2022), which in plough support a larger and more active microbial biomass with a greater demand for N.

These findings are important because microbial biomass is the major biologic N sink when plant roots are non present or when constitute N need is low (Drinkwater and Snapp, 2007), for case, later on spring fertilizer applications when plants are young. If in that location is sufficient agile C bachelor, so microbes tin can temporarily immobilize inorganic North and comprise it into organic N pools, which have a much longer mean residence time and can later be mineralized. Although this strategy may temporarily subtract the Northward available for crop uptake, over the longer term (weeks to months), plants benefit from microbial turnover and N mineralization as available C is depleted (Harrison et al., 2007; Hodge, 2004; Jackson et al., 2008; Schimel and Bennett, 2004). Because temperature and soil moisture are both fundamental controls on microbial processes and plant growth, North mineralized via microbial processes may exist more synchronous with constitute need than N added as fertilizer. Impacts of various crop rotations on labile soil C thus drive the microbial processes that back up greater North retentivity and mineralization, i.e., they support greater microbial North cycling capacity.

Improved water infiltration and memory in complex rotations may as well indirectly affect microbial N cycling processes and synchronicity with root N uptake via positive effects of soil moisture availability on microbial processes. Although soil Northward cycling is understood to be wet driven (Porporato et al., 2003), the combined furnishings of increased organic N, microbial biomass, and soil water retention on components of the soil N wheel take not been fully disentangled. At low soil wet content, connectivity between h2o-filled soil pores decreases, which reduces not only mass menses of inorganic N to ingather roots but also diffusion rates of enzymes and substrates regulating microbially mediated N cycling. This process may upshot in slower diffusion of microbial enzymes to SOM and, subsequently, dissolved organic affair products back to microbes, limiting microbial activity (Manzoni et al., 2022) and mineralization of organic N (Larsen et al., 2022). Slower diffusion of ammonium (NH_four ⁺) substrate to nitrifying leaner might also decrease nitrification (oxidation of NH₄ ⁺ to ${NO}_{three}^{-}$ ) (Stark and Firestone, 1995). These mechanisms imply that improvements in soil physical properties (e.g., aggregation, aeration, infiltration, water holding capacity) in diversified rotations may mitigate the negative effects of moisture limitation on microbial activity and thus subtract potential for N losses by tightening cycling between SOM, microbial, and mineral N pools. Reduced wet limitation, together with higher "active" soil C, may help explain the links betwixt observed increases in soil aggregate stability, SOC and total soil N, and microbial activity along a gradient of increasing rotation diversity and residue inputs (Tiemann et al., 2022).

Conversely, saturated soils (approximately lxx%–90% water-filled pore space) (Dobbie et al., 1999) with anaerobic conditions (Zhu et al., 2022) lead to N_iiO emissions primarily through denitrification (reduction of ${NO}_{3}^{-}$ to dinitrogen (N₂)). N₂O:Due north_ii ratios summit at high percent water-filled pore space and low oxygen availability (i.due east., field capacity) (Bateman and Baggs, 2005), implying that soil structure changes observed in complex rotations (Congreves et al., 2022; Karlen et al., 2006; Tiemann et al., 2022; Wienhold et al., 2006) could help decrease N_twoO production through increased soil aeration (Zhu et al., 2022).

Ditch-buried harbinger return: A novel tillage practice combined with tillage rotation and deep ploughing in rice-wheat rotation systems

Haishui Yang , ... Xinmin Bian , in Advances in Agronomy, 2022

4.four Greenhouse gas emission

Straw-derived C profoundly stimulates soil microbial activity, and thus will exist transformed into CO ₂ or CH₄ through aerobic and anaerobic respiration in the rice-wheat rotation system (Liu et al., 2022). Under DB-SR conditions, harbinger residues are buried below the ploughing horizons, not similar RT-SR past mixing straw fragments with surface soils, thus decelerating decomposition and straw-derived C transformation. Zha et al. (2013) measured C emissions from each process of DB-SR functioning and found that DB-SR-20 reduced total C emission by 13.71%, 34.19% and 28.37% in the wheat season, rice flavour and annual rotation comparison with RT-SR, respectively. Carbon emission was reduced by 11.66%, 24.xi% and 20.57% by DB-SR-40 in the wheat season, rice season and total year (Zha et al., 2022). In sandy soil conditions, Wu et al. (2015a) reported that DB-SR-20, DB-SR-twoscore and DB-SR-sixty annually decreased CO_two by fifteen.02%, 8.33% and 12.71%, CH₄ by 8.57%, 37.77% and 33.00% and Due north₂O by 14.v%, 14.0% and 14.0% when comparison with RT-SR in the rice-wheat rotation system, respectively. In the dirt soil weather condition, Hu et al. (2016) found that DB-SR significantly reduced CH_iv emission past 9.85% from rice paddies nether consecutive monitoring for 2 years in a rice-wheat rotation arrangement.

7.iv Detailed Relationships betwixt Soil Attributes

Soil MBC is usually correlated with soil organic matter; increasing soil microbial activity decreases SOC, because microbiological activeness requires a good supply of soil C. High temperature coupled with favorable soil moisture under plastic mulch typically accelerates decomposition of soil organic matter by soil microorganisms. Loss of SOC means the organization is no longer sustainable. Nevertheless, loftier crop yield within the RF arrangement will ultimately render more crop residue back to the soil, which should increase the SOC and meliorate soil fertility in the long run. Therefore, long-term inquiry is needed to decide the impact of RF systems on SOC dynamics and microorganism functionality and biodiversity in the soil.

Resilience in Complex Socio-ecological Systems

Julia Siebert , ... Nico Eisenhauer , in Advances in Ecological Inquiry, 2022

ii.4 Statistical assay

Soil invertebrate feeding activity was measured at 36 fourth dimension points, and soil microbial action was measured at 34 time points. Given that nosotros expected treatment effects to vary with time in a nonlinear mode, we used generalised additive mixed-furnishings models (GAMMs) to test the interactive furnishings of climate, state apply, and time on soil biological activity. We chose GAMMs due to their flexibility in including smooth functions of covariates without restricting the relationships to be linear, quadratic, or cubic. The model construction of the GAMM was: soil biological action ~ s (fourth dimension, climate) * s (time, land employ) * s (time, climate, land use) + (1 | mainplot/plot), with 's' indicating smoothing functions for GAMM. Experimental plots were nested within mainplots and incorporated as a random intercept for the experimental design. We applied GAMMs using the 'gamm4' bundle (Wood and Scheipl, 2022). The test statistics for GAMMs were obtained from the 'itsadug' package (van Rij et al., 2022). In addition, we compared the results from GAMMs with linear mixed effects models (LMMs), in which we tested the handling furnishings across time on soil biological activeness using the package 'nlme' (Pinheiro et al., 2022). For LMMs, a random intercept with mainplots nested within sampling time points, nested within years was included in the models. Nosotros deemed for repeated measurements by including a compound symmetry covariance structure, which fitted the data better than a starting time-social club autoregressive covariance construction based on the deviation in their Akaike information criterion (AIC) value. Invertebrate feeding action and microbial activity were log-transformed (log (10 + i)) to improve the fit of the model. The raw ways and standard errors of both response variables are presented in Table iii.

Tabular array iii. Hateful values of soil invertebrate feeding activity and soil microbial activeness. Shown are means of the not-transformed data (± SE) for the different state-use types (all-encompassing meadow, extensive pasture, and intensive meadow) under ambient and future climate conditions.

Soil microbial activity	1.87	0.06	1.78	0.06	1.84	0.06	1.77	0.06	1.59	0.05	1.53	0.05

The 'quantmod' packet (Ryan et al., 2022) was used to identify the nearest peaks (using the fifteen closest data points) in the time series information of soil invertebrate feeding activity under both ambience and future climate conditions. Later the identification of all peaks in the fourth dimension series (i.east. the local maxima after restricting the search to the nearest fifteen information points for each climate status), nosotros calculated the mean solar day difference between the ii highest peaks (among all the identified peaks, see Fig. 4) of invertebrate feeding activity for the two climate scenarios. Finally, LMMs (Pinheiro et al., 2022) were used to analyse the effects of climate, land apply, flavor, and their interactions on potential explanatory variables (i.eastward. plant root biomass, microbial biomass, soil water content, soil brute groups, pH, available C and North) using data available for spring, summer, and fall 2022 (Figs v–seven). In the case of establish shoot biomass, the effects of climate and sampling were analysed separately for each land-use type considering of the different mowing frequencies. A random intercept with plots nested within mainplots was included in the models. All statistical analyses were performed using the R statistical software version 3.5.one (R Core Team, 2022).

Cadmium Contamination in Water and Soil

Qaisar Mahmood , ... Shafaqat Ali , in Cadmium Toxicity and Tolerance in Plants, 2022

5.ii Furnishings of Cd on Soil Microbes

Soil is a habitat for a big number of diversified microbes (Vig et al., 2003 ). Soil microbial activeness is an indicator of soil quality ( Su, 2022). Cd contagion in soil has toxic furnishings on soil microbes, reducing their number and activities (Belimov et al., 2005; Khan et al., 2022, 2010a,b). Cd'southward issue on soil microbes depends on the soil blazon and Cd concentration in soil (Vig et al., 2003). According to Su (2014), microbial biomass in soil well-nigh a mine was reported to exist lower than soil abroad from the mine. Sensitivity of microbes to heavy metals depends on their species, strains of the same species, and activities of the aforementioned species (Giller et al., 1998). Microbial biomass carbon, basal respiration, and dehydrogenase activeness are indicators of Cd toxicity in soil (Liao et al., 2005). Khan et al. (2010a,b) plant that soil amended with Cd, especially at higher concentrations, changed the structure of the bacterial community. Adding Cd in the paddy soils profoundly enhances the inhibition of functions of the microbial community, and Cd bioavailability in paddy soil changes with time (Liao et al., 2005). Many soil microbes can tolerate heavy metals, and play a significant role in their mobilization and immobilization. When Brassica napus was inoculated with metallic-resistant PGPR, it enhanced the growth of plants grown in soil contaminated with Cd. Similarly, barley plants, when inoculated with auxin-producing and nitrogen-fixing PGPR, immobilized Cd and enhanced the growth of the barley plants cultivated in soil with toxic Cd concentrations (Belimov et al., 2005).

11.9 PKs in soils

This department presents and discusses published information on the product of soil PKs, the effects of antibiotics on soil microbial activity, and the issue of soil management and the importance of adsorption reactions on soil PKs. In spite of their natural occurrence, the biochemistry and chemistry of microbial PKs in vivo soils has received niggling attention. Nearly enquiry on PKs and the microorganisms responsible for their syntheses has been conducted in vitro in the laboratory. Soils are a source of many and diverse bioactive compounds involving PK structures that are produced by ethnic microorganisms (Gottlieb, 1976; Tomashow et al., 1997). About 30–50% of actinomycetes isolated from soil are capable of synthesizing antimicrobial compounds (Topp, 1981). In soil–plant ecosystems, the interactions of living organisms with their surroundings are complex and involve plants, microorganisms, insects, animals, and inorganic colloids. In soils, the microbial-synthesized PK antibiotics help the microbial producer to proceeds access to nutrients and the suppression of plant root pathogens, amongst other benefits. For example, isoepoxydon is an alkylaromatic compound synthesized by fungi and actinomycetes that causes growth interference betwixt Poronia punctata, a late colonizer of animate being dung and earlier colonizer species of Ascobolus furfuraceous and Sordaria fimicola (Gloer and Truckenbrod, 1988).

Harris and Woodbine (1967) examined a full of 560 bacterial isolates from four rhizosphere and eight nonrhizosphere soils and tested them for resistance to vii different antibiotics. They found marked differences between the overall levels of antibody resistance in the different soils. The bacteria isolates inhabiting the rhizosphere were more susceptible to antibiotics than the corresponding bacteria from nonrhizosphere soils. The latter authors also showed that just two–10% of the total soil bacterial isolates showed resistance to the seven antibiotics. In comparison, the bacteria populations in the rhizosphere of 10 plant species were shown to have a greater resistance to streptomycin than the comparable leaner from nonrhizosphere soil when assessed by a plate count technique (Dark-brown, 1961). Penicillin activity added to unsterilized soil at 1000 μg g⁻ⁱ completely disappeared after 2 weeks (Pramer and Starkey, 1951). The latter report, still, did not determine the potential effects of biotic decomposition and adsorption reactions past soil colloids on the disappearance of streptomycin.

Other studies show that microbial populations in diverse soils differ in their reactivity to antimicrobial compounds (Harris and Woodbine, 1967; Williams and Davies, 1965); and there is no universal antibody or set of antibiotics capable of inhibiting all the soil heterotrophic action. The optimum concentration of PK antibiotics and their deposition susceptibility need to exist investigated before conducting CO₂ soil respiration studies (Anderson and Domsch, 1973). Soil respiration studies show a dose response to added antibiotics later 24 and 48 h of incubation in selected soil samples (Thiele and Beck, 2001). There is little and inconclusive testify demonstrating the proportion and blazon of soil microorganisms that are susceptible or resistant to microbial PKs in situ. Published data clearly indicates, however, that some soil organisms and bacteria isolates have resistance genes to protect themselves from PKs secreted by other living organisms in soils.

The synthesis and stabilization of diverse PK antibiotics were studied in sterilized and unsterilized soil samples amended with organic residues and inoculated with Streptomyces aureofaciens and Streptomyces rimosus. The maximum amount of aureomycin found in the soybean-amended sterilized soil samples was 0.15 μg chiliad⁻¹ soil, and that in unsterile-amended soil samples was 0.03 μg yard⁻¹ soil after 16 days of incubation. In comparison, the corporeality of terramycin in the aforementioned soil treatments was nearly 6 times greater. Afterward 30 days of incubation, the amount of aureomycin was reduced by about 50% in sterile soil and by nearly 90% in unsterile soil (Soulides, 1965). The antibody glycotoxin produced by the soil saprophyte fungus, Gliocladium virens, to control soilborne pathogens was detected at concentrations between 0.2 and 0.37 μg cm^−three soil in dirt and composted mineral soil (Lumsden et al., 1992). Several antibiotic compounds persist in the environs and are not transformed (Winckler and Grafe, 2001). Antibiotic residues given to animals for treatment of affliction or growth promotion are found in soils, after manure application, at concentrations of 0.02 μg g⁻¹ soil (Aga et al., 2005; De Liguoro et al., 2003; Hamscher et al., 2002). In a different study, the concentrations of residual tetracyclines in soils ranged from 0.025 to 0.105 μg one thousand⁻¹, but sulfonamide antibiotics were not detected (Cengiz et al., 2010).

PKs are strongly adsorbed to organic and inorganic soil particles. Strongly adsorbed antibiotics to soil colloids may be leached from soils through preferential transport in macropores (Thiele-Bruhn, 2003). The strong adsorption of PK antibiotics to OM and dirt colloids in soils is associated with charge transfer and ionic interactions and not to hydrophobic sectionalisation. The distribution coefficient for the adsorption of antibiotics to soil materials varies widely depending on soil type and on the chemical construction and amount of the compound, and as expected, sorption is stronger in clay than in sand particle-size fraction (Thiele et al. 2002; Thiele-Bruhn, 2003). Aminoglycosides, tetracyclines, and tylosin are more strongly adsorbed to expandable than to nonexpandable dirt minerals while desorption of aminoglycosides was not observed (Bewick, 1979; Pinck et al., 1961a, 1961b). Effects of antibody addition on soil organisms include shifts in microbial communities and development of resistance nether frequent and loftier addition of these compounds to soils via animal manures. The reviewed published information conspicuously indicates that indigenous PK antibiotics and those of added to soil through manures or other beast residues results in rapid adsorption and fixation by soil organic and inorganic components, and thus their biological utilization and decomposition is largely prevented in soil ecosystems.

Grassland Functional Diversity and Management for Enhancing Ecosystem Services and Reducing Environmental Impacts

Michel Duru , ... O. Therond , in Agroecosystem Diversity, 2022

Management and Governance to Meliorate Ecosystem Services at the Local Level

Major problems in managing grasslands are uncertainty due to incomplete knowledge (e.chiliad., for C sequestration), incomplete command (e.g., by grazing), and complex internal feedback (e.g., due to soil microbial activity, especially when temporary grasslands are grown in rotation with crops) ( Duru et al., 2022a,b). In such situations, adaptive management is required as a structured approach that farmers and their advisors tin apply to design practices and assess trade-offs among competing ES (Birge et al., 2022) that occur at different spatial (field to farm) and temporal scales (e.thou., productivity during a growing flavour vs. stability over several years). Useful knowledge needs to be developed to help select grassland species to be grown in temporary grasslands considering characteristics of the product situation (livestock system, climate, and soil) and expected ES, as is already somewhat available for comprehend-crop species (Damour et al., 2022). Development of "interactive" knowledge databases that provide generic knowledge from science and tin incorporate farmer-feel feedback from a wide range of farming weather seems a promising noesis production and direction strategy (Duru et al., 2022a; Duru and Vertès, 2022).

At the landscape calibration, since experimentation is non possible, scenario planning is necessary to explore relations between spatiotemporal distribution and composition of grassland and expected ES at multiple levels (Birge et al., 2022). Simulation models are needed to assess land use scenarios ex ante, for example, to compare different landscape mosaics including grasslands to improve pest command (Parisey et al., 2022) or to create exchanges betwixt specialized crop and livestock farms (Moraine et al., 2022a). These challenges often crave a participatory design approach. Scenario planning tin accost the scientific dubiousness associated with land use modify and also consider social relationships (Moraine et al., 2022b). Ultimately, because scenario planning encourages exploratory dialogue about disquisitional uncertainties and risks that stakeholders may encounter, information technology serves as more than a decision-making model (Cobb and Thompson, 2022). Irresolute the agri-food chain to promote grassland-based animal products requires coordination amongst all stakeholders, particularly when defining specifications for grassland management, production limerick, or authorized processes, which guarantees to the consumer that products, as well as their related production processes, meet their expectations. Governance issues must be addressed when exploring such changes (Duru et al., 2022b).

Decomposition and Mineralization

Fifty. Wang , P. D'Odorico , in Encyclopedia of Ecology, 2008

Soil wet

Conditions of limited soil water availability reduce the rate of microbial action due to the emergence of conditions of microbial water stress due to dehydration, and to the reduction in the size of the water films coating the soil grains. Low wet contents limit the mobility and the supply of substrate to the soil microbes by diffusion through the soil solution. In moisture soils, microbial activity is limited by the depression soil aeration and the consequent limitations in the amounts of oxygen bachelor for the decomposition procedure. Thus, nether water-logging conditions typical of wetland soils, decomposition is for virtually function inhibited due to the limited supply of oxygen to the soil microbes and to the limited transport of the CO_ii produced in the decomposition procedure (soil respiration). The optimal environs for microbial activeness is provided past a warm soil that is both moist and aerated. These atmospheric condition are met with intermediate moisture contents betwixt those of dry and completely saturated soils. The effect of soil moisture is also modulated by other factors – in energy-limited surroundings, for example, boreal forest, higher moisture does not necessarily lead to higher decomposition rates. Soil moisture fluctuations, typical of arid and semiarid environments, are associated with pulses in the rates of decomposition and mineralization, with consistent pulses in the availability of soil mineral nutrients. Other abiotic factors such as solar irradiance, soil pH, and soil physical backdrop (e.one thousand., clay content) also bear on the decomposition rates. For example, it has been found that in arid environments litter decomposition tin can undergo a process of photodegradation, which provides a shortcut in the cycling of soil carbon.

Arthropod pests of tobacco (Nicotiana tabacum Fifty.)

Peter A. Edde , in Field Ingather Arthropod Pests of Economic Importance, 2022

Nonchemical control

Management of thrips and TSWV include the following cultural tactics:

●: Where available, use host plant resistance as a part of the cropping organization.
●: Destroy volunteer crops and annual weeds in cultivated fields to reduce overwintering convenance sites for thrips.
●: Maintain skillful soil fertility management practices, especially those that increase soil microbial activity, as this may reduce thrips attack.
●: Advisedly select crops in rotation to avert planting thrips-susceptible crops following crops that are known to requite good overwintering sites for thrips.
●: Apply trap crops to take advantage of the inherent preference of thrips to feed on more attractive plants.
●: Crops suffering from drought stress are more susceptible to thrips damage. Heavy irrigation, specifically sprinkler irrigation, or rainfall assist to dislodge thrips from plants, impale larvae, and suppress dispersal or destroy pupae in the soil by crusting or burial them in the soil.
