Insecticides use in field crops has grown increasingly prophylactic, which poses a potentially unnecessary risk to arthropod decomposers. These decomposers — including millipedes (Diplopoda), soil mites (Acari, mostly Oribatida), and Collembola act as alternative prey for generalist predators, facilitate crop-residue breakdown, can influence nutrient cycling. However, the abundance activity of ...

Severe soil organic carbon (SOC) depletion is a major constraint in rainfed agroecosystems in India because it directly influences soil quality, crop productivity and sustainability. The magnitude of soil organic, inorganic and total carbon stocks in the semi-arid bioclimate is estimated at 2.9, 1.9 and 4.8 Pg respectively. Sorghum, finger millet, pearl millet, maize, rice, groundnut, soybean, ...

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

The improvement of soil quality in agro-ecosystems is one the major objectives conservation agriculture (CA) strategies. objective this study was to evaluate, quantify and compare effects two tillage practices, four crop rotation sequences, residue management systems their interactions on a Haplic Plinthosol South Africa using Soil Management Assessment Framework (SMAF). evaluation done CA fiel...

Allelochemicals from sorghum [Sorghum bicolor (L.) Moench] residues may inhibit the emergence and growth of other crops. We examined effects two landraces, IS9456, a high sorgoleone producer, IS22320, zero producer. Residues were applied at 7.2 g, 14.4 g 21.6 kg-1 soil. Emergence maize (Zea mays L.), wheat (Triticum aestivum L.) soybean [Glycine max Merr.] tested in three glasshouse pot experim...

Management of plant litter or crop residues in agricultural fields is an important consideration for reducing soil erosion and increasing soil organic C. Current methods of quantifying crop residue cover are inadequate for characterizing the spatial variability of residue cover within fields or across large regions. Our objectives were to evaluate several spectral indices for measuring crop res...

Soil porosity estimated conventionally cannot provide the spatial distribution and geometrical properties of pore networks. This on-farm study assessed impacts grassland–cropland conversion on soil characteristics. aimed to quantify microscale changes in pores near surface (0–10 cm) under grasslands converted croplands managed with a rotation corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] ...

The presence of deep-burrowing earthworms can affect soil structure and in®ltration, therefore in ̄uencing agricultural productivity. We investigated the effects of deep-burrowing earthworm species on soil structure at the surface of chisel-plowed or ridge-tilled cropping systems in Pike County, OH, planted to corn (Zea mays L.). Earthworm populations were experimentally manipulated in ®eld encl...

We find that the minimum distance of the binary [137; 69] quadratic residue code is 21.
