Document Summary
Compare the most traditional furrow irrigation systems with the modern lepa systems. Relative number of irrigations in the growing season with explanation. Relative amount of irrigation water at each application with explanation. Several considerations such as labor and energy requires high costs. Since lower number of irrigations can still supply high quantity of water, not many irrigations are needed. More irrigation water is used at each application. Even though lesser irrigation is used, more quantity of water is used. This causes the soil to be really wet and causes poor root aeration. More time as furrows take up a huge area of crop field. Less number of irrigations in the growing seasons. It is not necessary to have high number of irrigations as each irrigation can use water efficiently. Less irrigation water is used at each application. The water is bubbled into small droplets which slowly flows continuously or rectilinearly through the crop field.
