Explanation:
Excess soil moisture also promotes root diseases like armillaria root rot and phytophthora root and crown rot. These diseases are present in almost all orchard soils and can severely shorten the productive life of trees. Other losses caused by over-irrigation include: Water lost to leaching.
Over-irrigation leads to water loss, increases energy use for pumping, causes leaching of nitrogen and other micro nutrients, and wastes time. Crop nitrogen needs, fertilizer costs, and nitrogen losses to groundwater also result from over-irrigation.
