We want to implement irrigation system for our tea farm of 10 Ha. Drip irrigation is not suitable for us as the slope is too high. So we are considering implementation of sprinkler irrigation in our project. Does some one have guidelines for designing sprinkler irrigation system? How to calculate the amount of fertilizers that can be applied through these sprinklers? Are there different norms for systems used for irrigation purpose (Vs) system used for irrigation plus fertigation purpose?
