However, surface irrigation has limitations because it increases the chance of human contact with the effluent. Common surface irrigation systems used are rill irrigation, furrow or border irrigation. Surface irrigation is practiced on only about 39% of the irrigated crop land in the USA but on far more, 85%, worldwide. of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation.
