Perennial biofuel and cover crops systems are important for enhancing soil health can provide numerous soil, agricultural, environmental benefits. The study objective was to investigate the effects of on hydraulic properties relative traditional management claypan soils. site included selected practices: crop (CC) no (NC) with corn/soybean rotation, switchgrass (SW), miscanthus (MI). CC mixture...

Remote sensing data provide required inputs for environmental modelling at regional to global scales and play an important role in monitoring agricultural land use with regard to EU agricultural subsidy and sustainable watershed management. To characterise the dynamics of agricultural parcels, it is important to have information about the crop type and the vegetation cover (VC) during the year....

Cover crops act as green manure adding organic matter to agricultural-soils. For legume green manures to be an effective nitrogen (N) source for organic farming systems, their N release must be in synchrony with crop N demand. The objectives of this study were 1) determine the decomposition rates of three common cover crops (white clover, (Trifolium repens,L) red clover (Trifolium pratense L.) ...

Terminated small grain cover crops are valuable in light textured soils to reduce wind and rain erosion and for protection of young cotton seedlings. A three-year study was conducted to determine the impact of terminated small grain winter cover crops, which are hosts for Meloidogyne incognita, on cotton yield, root galling and nematode midseason population density. The small plot test consiste...

Fusarium head blight (FHB) of small grains tends to be associated with certain environmental conditions, especially rain-induced wetness periods occurring near anthesis. A Geographic Information System-based model simulation which incorporates 4km resolution weather radar (NEXRAD)-derived precipitation estimates into a crop canopy energy balance-based scheme to estimate wetness duration periods...

In 1987, the United States Department of Agriculture (USDA-ARS) National Sedimentation Laboratory, in cooper­ ation with the Mississippi Agricultural and Forestry Experi­ ment Station (MAFES) and the Natural Resources Conservation Service (NRCS), initiated an interdisciplinary research project to develop profitable and environmentally sustainable conservation production systems for silty upland...

Plant diversification using cover crops may promote natural regulation of agricultural pests by supporting alternative prey that enable the increase of arthropod predator densities. However, the changes in the specific composition of predator diet induced by cover cropping are poorly understood. Here, we hypothesized that the cover crop can significantly alter the diet of predators in agroecosy...
