Percent soil organic matter (SOM), pH and crop yield are among the biophysicochemical process-driven soil health indicators (SHIs). However, identifying sustainable soil health conditions using these SHIs is limited due to the lack of Integrated Prod

Previous research has documented patchy distributions of entomopathogenic nematodes (EPNs) in the field, but more uniform distributions of EPNs could increase their biocontrol services in agroecosystems. Although laboratory studies have identified va

Spatial association between entomopathogenic and free-living nematode populations in soil were analyzed at the landscape scale. GPS coordinates were obtained for 479 locations where soil samples were collected to extract nematodes. Habitats sampled i

It is well known that Taylor's power law describes spatial aggregation, but its ecological interpretation remains elusive. Here we used data on spatial organization of soil nematode communities in urban landscapes to test relationships between nemato

Four organic transition strategies including tilled fallow (FA), mixed-species hay (HA), low intensity open-field vegetable production (FV) and intensive vegetable production under high tunnels (HT), each with and without annual compost amendment, we

The main objective of this study was to characterize variation in soil chemical properties with length of urbanization period and distance to roads. Urban boundaries from 1920’s (old), 1960’s (middle) and 2000’s (new) were identified for three

Human activity in urbanizing areas often disturbs the soil profile, but little is known of its effects on subsequent soil food web dynamics and biogeochemical cycling. We assessed dynamics of the soil nematode food web and nutrient pools in tall fesc

The impact of long-term turfgrass management practices on soil nematode population and community structure and nutrient pools were studied in replicated Kentucky bluegrass ( Poa pratensis ) plots managed under 9 different organic- and mineral-fertili

Under microcosm conditions, changes in the soil microbial biomass, respiration rates, and nitrogen pools as indicators of potential non-target effects of entomopathogenic nematodes on soil, were evaluated. Two tests were conducted using soil collecte

The impacts of two organicsoil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their
