Less evaporation losses of water as compared to surface irrigation. ­Though initially expensive -- between $500 and $1000 per acre -- and not suitable­ for many areas, the economical advantages of drip irrigation can be further enhanced by placing the irrigation tubing about 5 inches (about 12.7 centimeters) below the surface. Drip Irrigation . Smooth, graded, gravity-driven slopes suit surface irrigation best. Pennsylvania has approved the use of drip irrigation as an alternate wastewater disposal method for on-lot sewage. Distribution manifolds should be 25 mm uPVC or polyethylene pipe buried 300 mm below the ground surface. ... A zero value represents land use types that limit the suitability of land for surface irrigation such as water bodies, wetlands, urban areas, forest, and protected areas. irrigaTiOn sTraTegy The amount of water that can be applied in a single application via conventional surface irrigation (that is, flood, furrow, or border irrigation) or, to some extent, sprinkler irrigation, depends upon the ability of the soil to absorb water. Advantages of drip irrigation Maximum use of available water. Irrigation should be optimum because even over-irrigation can spoil the crop production. Terminology . Surface Water vs. Maximum crop yield High efficiency in the use of fertilizers. Subsurface application of water aimed directly at the root zone improves yields by reducing the incidence of disease and weeds. In fact, in the United States in 2000, about 29.4 million acres were irrigated by flood irrigation as compared to about 28.3 million acres irrigated by spray irrigation. Low labour and relatively low operation cost. Subsurface microirrigation is suitable for almost all Crops and especially for high-value fruit and vegetable Crops, turf and landscapes.
