META TAG: Precision farming.... a next step towards doubling farmers income.
precision agriculture is an approach where inputs are utilised in
precise amounts to get increased average yields compared to traditional
cultivation techniques. Hence it is a comprehensive system designed to optimize
production by using a key elements of information, new tech in agriculture, and management, so as to increase production efficiency,
improve product quality,
improve the efficiency of
crop chemical use,
conserve energy and
protect environment [1]. Thus, precision farming is an appealing concept
and its
principles quite naturally
lead to the
expectation that farming
inputs can be used
more effectively, with subsequent
improvements in profits and
environmentally less burdensome
production. The smart farming developments of today
can provide the modern technology for the environment friendly agriculture of
tomorrow. Especially in
the case of small
farmers in developing countries,
precision farming holds
the promise of substantial yield improvement with minimal
external input use .
NEED OF PRECISION FARMING : The global food system faces
formidable challenges today that will increase markedly over the next 40 years.
Much can be achieved immediately with advanced technologies and knowledge, given sufficient
will and investment.
But coping with
future challenges will require
more radical changes to the food system and
investment in research
to provide new digital solutions to novel problems. The decline in
the total productivity, diminishing and degrading natural ecosystem,
stagnating farm incomes, lack of eco-regional approach, declining and fragmented land holdings, trade
liberalization on agriculture, limited
employment opportunities in non agriculture sector, and global climatic variation have become major concerns in crop production and development.
Therefore, the use of recent technologies adoption is seen as one key to increase crop production in the future. Instead of managing an
entire field based
upon some hypothetical
average condition, which may not
exist anywhere in the field, a
precision farming approach recognizes
site-specific differences within
fields and adjusts management
actions accordingly. Farmers
usually are aware that their
fields have variable yields across the landscape.
