Effect of fresh water supply on agriculture in the southwest of the Netherlands.
AbstractSoil water deficits for twelve crops during each summer from 1933 to 1980 were calculated for a 15,000 ha region of southwestern Netherlands, and the chloride load of the drainage ditches, due to the seepage of salt water from the sea, was determined. Water requirements for sprinkling irrigation and for flushing the water courses for quality control were computed. The maximum water requirement for sprinkling and flushing was 3.4 mm day-1. The average increase in crop yields due to sprinkling ranged from <5% to 20%, depending on the crop. The economic effects of this water supply are examined.
