Abstract:
Agriculture provides for the most basic needs of humankind: food and fiber. Precision agriculture is based on information technology, which enables the producer to collect information and data for better decision making. Precision agriculture is an emerging farm management strategy that is changing the way people farm. Precision farming (PF) refers to the use of geographical information to determine field variability, ensure optimal use of inputs and maximize the output from a farm (yield). Large tracts of land usually have spatial variations of soils types, moisture content, nutrient availability and so on. Therefore, with the use of remote sensing (RS), geographical information systems (GIS) and global positioning systems (GPS), farmers can more precisely determine what inputs to put exactly where and in what quantities. This information helps farmers to effectively use expensive resources such as fertilizers, pesticides and herbicides, and more efficiently use water resources.
