Tons of soil are lost from agricultural fields in Nebraska each year as a result of water erosion. The accelerated loss of topsoil reduces the availability of plant nutrients and water needed for optimum crop production. In addition, the eroded soil frequently moves into surface waters causing sediment to be deposited in streams and reservoirs and nutrients to be released into other biological systems. The purposes of this workbook are to provide an understandng of how soil erosion estimates are determined, to estimate erosion control resulting from numerous cropping systems, and to inform the producer of alternative practices which may ...

This NebGuide will help you identify soil compaction and determine if compaction is limiting yield. Soil compaction is primarily caused by working or driving on wet fields. Compaction can develop at or below the soil surface (Figure 1) and can lead to inefficient fertilizer and water use and reduced yields. Observation of crop growth and soil surface conditions can give clues as to the extent of soil compaction.
