LDSF Topsoil Constraint
The soil constraint index indicators based on either a low threshold where values below which are probable impediments to plant growth and high threshold where values above which are also likely to imped plant growth or contribute to negative environmental outcomes.
Many of these constraints are challenging to address. These constraints may be a result of soil forming factors specific to this site and/or management practices that have gone on for decades. In general management practices that reduce soil erosion or increase soil organic matter are likely to have positive impacts on nutrient constraints as well as some physical constraints. Developing management practices for nutrient additions and cycling that are appropriate for agricultural production in the watershed is critical. While this soil constraint index may help to identify areas of particular concern and enable monitoring of overall soil health, site specific management recommendations need to be developed though crop trials.
