|What is a precision agriculture||
Precision agriculture is a new concept where the minute changes in nutrient will be taken care off. It make use of development in information technology, to enable the producer to collect information and data for better decision making. The concept of precision agriculture offers the promise of increasing productivity while decreasing production cost and minimizing environmental impacts.
|Tools in precision agriculture||
Global Positioning System (GPS) – a
referencing device capable of identifying sites within a field
Sensors and dataloggers – crop, soil and climate information can be monitored at a high frequency using these technologies;
Geographic Information Systems (GIS) – maps of these attributes can be generated and analysed using simple browsers or complex models
|GPS role in Precision Agriculture.||The use of GPS in Agriculture is limited but it is fair to expect wide spread use of GPS in future. Recently a GPS-based crop duster (precision GPS Helicopter), which can spray an area as small as 4 X 4 mtr. is attracting great attention. Some progressive farmers are now beginning to use GPS for recording observations. Such as weed growth, unusual plant stress, colouring and growth conditions, which can then be mapped with a GIS programmes.|
|Remote sensing and Sensors for PF||
Remote sensing techniques play an important
role in precision farming by providing continuous acquired data of
agricultural crops. Remote sensors image vegetation, which is growing on
different soil types with different water availability, substrate, impact of
cultivation, and relief Sensors use for the following applications:
Soil Properties Sensing: Soil Texture, Structure, and Physical Condition Soil Moisture; Soil Nutrients.
