Show Drainage Drainage problems in the Lower Colorado Region are generally caused by three factors: poor management of irrigation water, unfavorable drain- age characteristics of the subsoil, or unfavorable topography of the area being irrigated. Each of these factors, singly or in combination with others, causes water to accumulate in and/or on the soil. As a result, the soil becomes waterlogged, thus, plant production is reduced. Much progress has been made in the correction of drainage problems, but most of the land that has been irrigated has had some drainage problems. Typical row irrigation operation. kO |
