Irrigation Optimization

Since there are no realistic opportunities for the introduction of lucrative cash crops, efforts have been directed towards getting the best results out of the crops traditionally grown such as maize, wheat, dry bean and lucerne through a combination of approaches. These include both the implementation of the latest equipment, effective irrigation systems, and the use of various management and decision support systems. The reduced use of water has allowed the farm to increase the area under productive irrigation with no increase in allocation.

At a capital cost of US$400,000, the project successfully increased crop yield per unit of water withdrawn compared to other farms in the country and internationally. A reduced fertilizer bill resulting from a targeted application of fertilizer to crops and additional outcomes resulted in a total volumetric impact of 627,000m3/year.
