Maps are an important part of a Nutrient Management Plan. Using digital orthophotos of the farm, the fields can be identified. Accurate acreages are computed for precise crop records and nutrient recommendations. Then Digital soil surveys are layered over crop fields to determine drainage and yield capacities. Environmentally sensitive areas such as wells, streams, lakes, ponds, and shallow to bedrock are located and appropriate setbacks or buffers are delineated.

Ultimately the GIS map is linked to the farm crop records. A variety of field attributes can be mapped including soil test results, fertilizer and manure recommendations, and crop yields to help make informed nutrient management decisions.

Below is an example of a GIS map for a Nutrient Management Plan that has fields, acres, with 100 feet Well Buffer for manure and nitrogen application and 25 feet nitrogen and tillage Setback.
