                     PRECISION FARMING

DEFINITION:

Precision Farming or precision agriculture (PA)  site is a farming management concept based on observing, measuring and responding to inter and intra-field variability in crops

Ø Concept of precision includes variation in crop & soil properties with in a field. 

Precision agriculture aims to optimize field-level management with regard to:

·         crop science: by matching farming practices more closely to crop needs (e.g. fertilizer inputs);

·         environmental protection: by reducing environmental risks and footprint of farming (e.g. limiting leaching of nitrogen);

·         economics: by boosting competitiveness through more efficient practices (e.g. improved management of fertilizer usage and other inputs).

Precision agriculture also provides farmers with a wealth of information to:

·         build up a record of their farm;

·         improve decision-making;

·         foster greater traceability

·         enhance marketing of farm products

·         improve lease arrangements and relationship with landlords

Technologies adopted for precision farming:

                    1.GIS(global positioning system)

                    2.GPS(geographical processing system)

                    3.remote sensing& yield monitoring

ADVANTAGES:

Precision farming is an gricultural university innovation.

TNAU started precision farming in 2004 at 2 districts mainly dharmapuri & krishnagiri.

400 hectares selected for precision farming

TECHNOLOGIES USED IN PRECISION FARMING:

                           1.drip & fertigation

                           2.community nursery

                          3.field preparation

                         4. crop production technologies

CONSTRAINTS OF PRECISION FARMING:

Lack of infrastructure ICT based farming

Absence of appropriate skils and the potential users of ICT

Lack of appropriate content

Knowledge and technological lack
