Water is a major input resource in all horticultural operations. Irrigation management practices have the potential to strongly influence both the quantity and quality of crop produced. In many cases, water is both a limited and limiting resource to horticultural production. However, the ability to irrigate does not automatically guarantee profitability and long term sustainability of horticultural farms. Inappropriate or inefficient irrigation practices may lead to crop stress, disease and / or loss, as well as groundwater and surface water contamination, erosion or salinity problems.
