Irrigation strategies based on uncertainty and relation of total irrigation, risk of crop stress and deep percolation drainage.
Explore the posibility to reduce drainage from deep percolation while mainatining the risk of a water stress event at acceptable levels (<5%). The relationship between drainage and risk of crop water stress is explored, more specifically:
The relation between the amount of irrigated water, drainage and crop water stress likelihood.
How much water can be saved and drainage reduced by adjusting the irrigation dosage, while keeping the risk of crop stress acceptable?
What influences do uncertainty in soil parameters and evapotranspiration have on drainage and risk of crop stress predictions?
