Whilst drip irrigation is based on economic decisions, the associated benefits are quite significant. This method of irrigation consumes 60-70 percent less water and growers are able to reduce the amount of nitrogen they generally apply by putting it through drip irrigation systems. It helps to keep the moisture levels in the field at optimum levels all the time. Drip irrigation allows water to permeate the soil slowly and helps improve root growth resulting in healthier plants. Consequently, crop yields increase and operational costs are greatly reduced.
