Subsurface drip irrigation of row crops: a review of 15 years of research at the Water Management Research Laboratory

Germination and growth of Puccinellia tenuiflora in saline-sodic soil under drip irrigation

“…As a result, relative to other irrigation systems, drip irrigation can increase plant yields, reduce evapotranspiration (ET) and deep percolation, thereby decreasing the risk of soil degradation and salinity (Batchelor et al, 1996;Ayars et al, 1999;Karlberg and Frits, 2004). Moreover, drip irrigation can supply water at low discharge rates and high frequencies over an extended period, thus minimizing the salinity levels in the soil water as a result of the leaching of salts (Keller and Bliesner, 1990).…”

Produção de almeirão em função de níveis de fertirrigação nitrogenada e disposição de mangueiras gotejadoras nos canteiros

“…A irrigação por gotejamento subsuperficial é uma variação da tradicional irrigação por gotejamento, onde os tubos e emissores são enterrados, diminuindo as perdas por evaporação da superfície do solo, podendo reduzir o consumo de água em até 50% (AYARS et al, 1999).…”

Utilizing Subsurface Drip Irrigation and Conservation Tillage in Cotton Production Systems

“…Since agriculture is a major consumer of water for food and fiber production, it becomes critical to use efficient water delivery systems to crops, in addition to utilizing the most drought-tolerant water-efficient crops, cropping systems, tillage practices, and plant genetic materials available in sustainable crop production. Subsurface drip irrigation (SDI) is perhaps the most efficient water delivery system to roots of plants, producing crop yields equal to or greater than other irrigation methods and, in many cases, requiring less water and improved water-use efficiencies [3][4][5][6]. In regions where irrigation well capacities are low and in cases where available irrigation water is saline or where shallow water conditions are saline, SDI, compared with surface irrigation systems, offers the greatest potential to increase yields and irrigation water use efficiency [7][8][9][10].…”
