A range of chemical, physical and biological processes are important for sustained productivity and environmental quality in agricultural systems. Farmers and scientists share a concern with soil health, and this leads to questions for both measurement and management. An essential step is to define the context and the key functions required of a soil at the scale of interest (e.g. farm, drinking water catchment, region). Only then can appropriate indicator measurements be selected. Current soil health frameworks across the world commonly use organic matter (carbon), pH, extractable phosphorus, and various indicators of soil structure/water storage. A framework of interpretation shows whether the measured values are acceptable or whether one or more soil functions are constrained. A number of the soil health frameworks in practical use present the soil health indicators in a scorecard using traffic light coding to direct users towards guidance for improved soil management on-farm.

On Farm

On-farm water storage (OFWS) systems are best management practices that consist of a tailwater recovery (TWR) ditch used with a storage pond to provide irrigation water and improve downstream water quality. These systems have been increasingly implemented in the southeastern US, but the individual and cumulative effects of these systems on a watershed scale are unknown. In this study, the runoff, nutrient, and sediment loads entering a TWR ditch in an agricultural catchment were quantified, and contributing sources were identified using the annualized agricultural non-point source (AnnAGNPS) model. Fields with larger areas and soils with a high runoff potential produced more runoff. The volume of runoff exceeded the TWR ditch storage volume approximately 110 times, mostly during the winter and spring seasons. During years when corn and winter wheat were planted, NO3–N loads increased because these crops need nitrogen fertilization to grow. Planting winter wheat in priority subwatersheds reduced the total phosphorous (TP) and sediment loads by about 19% and 13%, respectively, at the TWR ditch inlet. Planting winter wheat can reduce runoff, TP, and sediment loads but also result in higher NO3–N loads. AnnAGNPS simulations quantified the benefits of an OFWS system to advance the understanding of their impact on water availability and quality at a watershed scale.
