Figure 4.7: simulation of irrigation water for crops4.3.2 step 2: evaluate the effective use of irrigation waterThere are 2 methods of efficient water use: (i) use the formula return (bronze) on the amount of water use (m3), this formula applies when the cultivation of many types of trees in different colors. (ii) use the formula the ratio of productivity (kg) on the steam escape draw crop (m3, ETc), this formula applies when the same type of tree farming. The process of determining the effective use of water for crops is presented in Figure 4.8.
