Subsurface application of water aimed directly at the root zone improves yields by reducing the incidence of disease and weeds. Germination of annual weed seed is reduced, which lowers weed pressure. Water is conserved, fertilizer efficiency is enhanced, and labor needs are reduced. In addition, field operations are possible, even when irrigation is applied. The applied water moves by soil matrix suction, eliminating the effect of surface infiltration characteristics and saturated condition of ponding during irrigation.
Application is uniform and highly efficient.
Wetting occurs around the tube and water moves out in all directions. Depending on the soil type, the downward movement may be enhanced by gravitational pull. A subsurface-drip or microirrigation system is flexible and can provide frequent light irrigations. This is especially suitable for arid, hot and windy areas with limited water supply. Crops Subsurface microirrigation is suitable for almost all Crops.
