How GIS can improve agriculture

SOILMAPS: This is one of the most important maps available to a farmer for obvious reasons. This map shows you what kind of soil the field consists of, what the ph is, what nutrients are in the soil, and how well the soil drains.

DEMS: Short for Digital Elevation Models, this map is useful in showing where water flows, and how well it flows. This information can reveal areas that fertilizer and pesticide build up can be a problem. It can also show the farmer the areas that might be draining to fast removing needed fertilizers.

HYDROGRAPHY: This type of map deals with water issues. By revealing the flow and drain patterns of water, the farmer can better determine irrigation issues that might not be readily known by just looking at the field with the naked eye. This allows for more precise control of water resources resulting in reduced water usage.

Even though precision farming is still a fairly new field of research, it has a lot of exciting possibilities that the agriculture industry can greatly benefit from. A lot of farmers have already started using this technology and are experiencing positive results from the information GIS provides.
