12.1 The real value from Precision Farming is that the farmer<br />

can perform more timely tillage, adjust seeding rates, fertiliser<br />

application according to soil conditions, plan more crop protection<br />

programs with more precision, and know the yield variation within<br />

a field. The site-specific management (or Precision Farming) is<br />

farm-size and production-system neutral. Precision farming will<br />

make agriculture “information intensive”, which will impact rural<br />

economies. Despite potential of economic and ecological benefits,<br />

adoption of precision technologies is very slow through out the<br />

World. The reasons for limited implementation of Precision<br />

farming in Asian Countries are as follows:<br />

• Small land holdings<br />

• Cost-benefit aspect<br />

• Heterogeneity of cropping system<br />

• Lack of local technical expertise<br />

• Knowledge and technological gaps<br />
