• Tillage intensity increased soil organic C losses and risks of wind water erosion. Occluded POM was more management-sensitive in smaller than larger sized aggregates. Maximizing plant inputs via cropping system type partially mitigated negative tillage effects. Soil disturbance from N management limited mitigating effects system. increases the susceptibility agricultural soils to erosion carb...

Tillage and crop rotation system effects on corn (Zea mays L.) growth and development have been studied extensively over the past 30 years, but most studies have principally focused on the effects of tillage and crop rotation on mean corn response parameters such as plant height, grain moisture content, and grain yield. As a result, many agronomists and growers have concluded that instances of ...

The ARS Root Zone Water Quality Model (RZWQM ver. 3.25) was used to simulate the effect of field measured macroporosity on atrazine transport to subsurface drain lines. Field data on atrazine concentrations in subsurface drain flow from corn fields, for modified no-till (mNT) and moldboard plow (MP) systems, were used to evaluate the performance of the RZWQM for the growing seasons of 1990, 199...

Livestock development in rainfed areas is slower due to the inadequate supply of nutritious fodder. Mono-cropping systems also have a negative impact on forage yield and nutrition as cereals are deficient protein. Hence, there dire need grow with legumes improve quality. Therefore, two-year field study was undertaken evaluate winter cereal–legume their mixtures viz. oats (cv. PD2-LV65), barley ...

Snow and ice removal and clearing roadways after a winter storm account for major portion of roadway agencies located in snowy region’s maintenance budget. With the decreasing funds and increasing demand from the motoring public for mobility, roadway agencies are continuously looking for new innovative approaches for winter maintenance operations. One of the main focus of these approaches inclu...
