Precision farming is the application of technology to manage the heterogeneity within a field. Traditional agriculture considers a field as a homogeneous unit. Fields used to be smaller and more uniform, and field boundaries were probably adapted to get uniform fields. As a result of mechanization, farmers are able to work bigger areas and fields became bigger and more variable. Farmers and agronomists are looking for tools to manage the local differences in fields. Precision farming is a tool to handle the spatial and temporal variability and creates a framework to understand and control the (local) processes in the field. An ensemble of collected information (including yield maps, soil maps, multi-spectral satellite remote-sensing images, etc.) can be used to develop management strategies that reduce needed inputs, and result in higher profitability, environmental protection and/or higher yields.
This name includes a group of practices that are also known as, or include, the following; conservation tillage; no-till farming; high-residue farming. It is based on minimal or no cultivation, and sowing directly into the ground after the removal of the previous crop. It often involves increased use of herbicides to control weed growth.
