Site specific management

• In contrast to conventional agriculture, site-specific crop management, or more simply site-specific management (SSM), attempts to manage soil, pests and crops based upon spatial variation within a field
• Site-specific management is a form of precision agriculture where decisions on resource application and agronomic practices closely match crop requirements as they vary within a field; consequently, the collective actions are differential rather than uniform.
• The aims of SSM are to apply inputs (e.g. irrigation water, fertilizer, pesticides, soil amendments, etc.) when, where and in the amount needed to optimize crop yield.
