A better understanding of how bermudagrass (Cynodon spp.) regrowth is influenced by production inputs will aid in advancing precision management. The objectives were to evaluate the effect of irrigation and nitrogen (N) on normalized difference veget

Variable-rate irrigation (VRI) systems have the potential to conserve water by spatially allocating limited water resources. However, when compared to traditional irrigation systems, VRI systems require a higher level of management. In this 3-year st

In the southeastern region of the U.S., the cattle industry has a critical need for sustainable hay production. Yet this production is threatened by frequent short-term regional drought. This drought threat can be mitigated by properly managed irriga

Availability of spatially-indexed data and crop yield maps has caused increased interest in site-specific management of crop inputs, especially water and fertilizer. As commercial equipment to implement site-specific applications of water and nutrien

The rapid expansion of animal production in the eastern U.S. in the 1990s resulted in large quantities of concentrated animal waste that must be utilized or disposed of in an efficient and environmentally friendly manner. To address these environment

In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short-term droughts and yield-reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomi

Site-specific irrigation is defined as delivering different prescribed depths of water to specific areas in irrigated fields. Since the 1990s, site-specific irrigation research has been expanded to include the delivery of water and nutrients to speci

In the US SE Coastal Plain, adoption of site-specific farming has lagged behind that in the upper Midwest. While reasons for this may be both social and economic, it appears that the importance of the problem represented by yield variation on product

In the southeastern USA Coastal Plain, spatial variation in soils causes extreme spatial variation in grain yield, as seen in yield maps. Corn (Zea mays L.) appears to be particularly susceptible to soil variation, espedally during periods of drought

The effectiveness of four sediment removal/water control treatments, each designed to dewater the 155-m3 sedimentation basin in 24 h, was evaluated using 100-m3 inflow hydrographs (35-mm, 2-yr runoff events) from a 0.4-ha denuded construction site co
