Description

Site specific management of plant nutrients for crop production begins with an inventory of soil test levels in a field. Fertilizer recommendations are based on the expected response to addition of fertilizers as a function of soil test levels. Therefore, the accuracy of site specific fertilizer applications depends on how accurately the nutrient status of soils is mapped. Mapping accuracy usually increases as fields are divided and sampled as smaller areas.
