Abstract: | ABSTRACT The feasibility of predicting total summer crop water use by grassland, based on early or pre-season soil moisture reserves, was investigated. Tests were based on the correlation over time between simulated soil moisture and related variables at six South African climate stations. A weather driven computer budget model was used to simulate daily soil moisture reserves. Results indicate that early prediction of seasonal crop water use is not feasible, but that deep soil moisture is stable enough over time to be a reliable monitoring variable for crop growing conditions. Moisture stored in the deep soil has good potential for monitoring more severe drought conditions. |
