In-Field Variability of Terrain and Soils in Southeast Kansas: Challenges for Crop Production.

A particular challenge for crop production in southeast Kansas is the shallow topsoil, underlain with a dense, unproductive clay layer. Concerns for topsoil loss have shifted production systems to reduced tillage or conservation management practices. However, nutrient and sediment loss is still a problem in the high-rainfall area. To improve crop production and further adoption of conservation practices, identification of vulnerable areas of fields is needed. Publicly available high-resolution imagery products and terrain maps can provide information on field conditions. This research explores within-field variability of farm production fields and uses online databases to collect information on vegetation and topography. The information can be used to develop protocols for alternative management to protect vulnerable areas and reduce topsoil loss.
