And for those people who are producing cash crops, i can propose a better
way of Intelligent farming which we are doing in Yuktix at present. We are
doing 2 way communication through GPRS module + MCU (Micro-controller unit)
+ sensors (Humidity + Temp + soil wetness + soil temperature) + Leaf
Wetness sensor  for some greenhouse and cash crop farmers. Let me know if
this thing seems to be of any interest.

I can help out in figuring the best possible hardware + software solution
if we want to do in DIY manner for non-cash crop farmers.
