Drip Irrigation and Soil :: Agriculture Agricultural Essays

fall Irrigation and SoilIntroduction Irrigation has had a unattackable effect on agricultural history, from its use by Egyptian and Iranian farmers over 2500 years ago through modern agriculture (Troth 1980). The about common irrigation techniques of today are furrow, oversupply, sprinkler and drip. Furrow and flood both flood the irrigated area, sequence sprinkler and drip are direct applicators. Drip irrigation is gaining popularity for its power of irrigation.Drip Irrigation Drip, or trickle, irrigation is a process of selective water use. A issue of emitters are placed both on or below design level. Placement of emitters is numerous in order to directly apply water to the crop. A pressurized pipe system supplies the emitters with water which then wets the soil indoors the root zone. Frequently, fertilizers are also utilize using this method. Water susceptibility is one of the most important characteristics of this recently developed technique. 90% of applied water i s available for crop use (Troth 1980). The constant presence of water in the soil has a positive effect for crops. (Bresler, 1977). Water efficiency also provides for a slower application of water to the soil. The application regularize controls infiltration rate which allows for a more uniform wetting in the individual root zone. In furrow and flood irrigation, waterlogging and water mutant posterior cause evaporation losses, plant violate, and erosion (Singer, 1996). Selective application prevents such instances from occurring under drip irrigation.Effects on SoilIrrigation plays a significant role in soil structure. The effects could be either beneficial or harmful to the soil, while separately affecting its briefly term crop productivity. Long-term violate to the soil, however, will result in decline of soil productivity. Farming techniques which use earth-moving machines can appear in effect(p) for crop production, but will eventually damage the topsoil (McLaren, 1990). corroding Any irrigation will decided role in the structure of a soil. The effects could be either beneficial or harmful to the soil, while separately affecting its short term crop productivity. Long-term damage to the soil, however, will result in decline of soil productivity, and regardless of the sign bountiful harvests crop yield will decrease. For example, farming techniques which use earth-moving machines can appear effective for crop production, but will eventually damage the topsoil which thereby decreases crop productivity (McLaren, 1990). Erosion is a substantial contributor to deterioration of soil quality. Flood and furrow irrigation use a high influx of water to immerse the crop area.
