Losses from agriculture can be significant to the grower, rancher, dairyman, and to the environment. While valuable topsoil, nutrients, herbicides, and pesticides are lost in both rain and crop irrigation events a component is also lost that is becoming more valuable - the water itself. As the runoff and erosion processes carry away these components there are changes to the soil itself which often results in crusting, lower infiltration, and faster transevaporation rates, further complicating water management and exacerbating immediate plant emergence issues, stress during growth cycles, and ultimately reducing plant yield. The environment can suffer as well as these components move off the farms and feed lots and into common water sources either through runoff, ground seepage, or discharge irrigation. Non-point source pollution is taking a narrower track in definition and scope in order to protect common waters and land loading from specific as well as general pollutants.
