There is a continual dialog about the food required to feed a population of nine billion people by 2050 and the changing climate and the impacts on food production and food security.

With rising commodity prices and increasing recognition of land as a stable investment, agricultural land values have experienced unprecedented increases as evidenced by Iowa recently documenting a $20,000 per acre agricultural land sale. Rising land values and high commodity prices have many implications ranging from limiting opportunities for beginning farmers to devaluing the implementation of conservation practices; potential income losses associated with either real or perceived reduced commodity production drive the conservation practice devaluation. In selected situations, conversations suggest practices are removed simply for operator convenience. From a myopic economic perspective conservation is a cost to the producer or land owner and not an investment in the property.

Midwestern row-crop agriculture is recognized as being highly productive, but is also cited for impairing surrounding ecosystems and impacting environmental quality. Water quality is a key metric utilized to characterize the health of an agricultural watershed. Therefore, it is important to know how new or alternative management practices impact water quality. With this in mind, the Kansas Agricultural Watershed (KAW) Field Laboratory was created in 2014 to study the effects of agricultural systems on water, sediment and nutrient losses. The goal of the KAW field lab is to evaluate and develop sustainable conservation practices that protect water quality, maintain yield and profitability and provide producers with flexible options for management of crops and nutrients.
