Subsurface Drip

In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high water tables are one of the most inefficient methods of irrigation, though some irrigation management practices can contribute to better soil moisture uniformity. Subsurface drip irrigation systems apply water below the soil surface by microirrigation, improving the water distribution and time required to raise the water table for seepage irrigation.

Subsurface Drip

Compared to other irrigation methods, drip irrigation systems (DI) are considered one of the most efficient form of irrigation. Subsurface drip irrigation allowed reducing water losses by evaporation, runoff, and deep percolation comparing to other irrigation systems supplying water on soil surface. Field evaluation of Uniformity of water applications and its stability, however, are still a matter of controversy and deserve more investigation, since the collection of water discharged needs to excavate the soil around the emitters. Experiments carried out at the Department of Rural and Agrifood Engineering of Polytechnic University of Valencia allowed describing a methodology to assess the performance of drip irrigation through hydraulic characterizations and an emission uniformity coefficient, using the step by step models. Calculations evidenced that operating pressures on emitters ranged between 127.6 kPa and 131.7 kPa, whereas the corresponding flow rates varied from 4.00 L/h and 4.07 L/h, with an average value of 4.02 L/h. Variability in the emitters’ flow rate resulted very limited due to the short length of the lateral (25.6 m). However, more attention should be paid to this for a longer field dimensions. Consequently, the value of emission uniformity coefficient was equal to 96.3%, testifying the uniform water distribution within the sub-plot.

HighlightsSubsurface drip irrigation (SDI) has continued to expand in irrigation area within the U.S. during the last 15 years.Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, and turf).SDI usage on many crops has matured through research and development of appropriate strategies and technologiesDespite some persistent challenges to successful use of SDI, important opportunities exist for further adoption.Abstract. Subsurface drip irrigation (SDI) offers several advantages over alternative irrigation systems when it is designed and installed correctly and when best management practices are adopted. These advantages include the ability to apply water and nutrients directly and efficiently within the crop root zone. Disadvantages of SDI in commercial agriculture relative to alternative irrigation systems include greater capital cost per unit land area (except for small land parcels), unfamiliar management and maintenance protocols that can exacerbate the potential for emitter clogging, the visibility of system attributes (components and design characteristics) and performance, and the susceptibility to damage (i.e., rodents and tillage) of the subsurface driplines. Despite these disadvantages, SDI continues to be adopted in commercial agriculture in the U.S., and research efforts to evaluate and develop SDI systems continue as well. This article summarizes recent progress in research (2010 to 2020) and the status of commercial adoption of SDI, along with a discussion of current challenges and future opportunities.

The effects of ammonium-based fertilisers on the soil pH of vegetable beds that utilised subsurface drip irrigation (SDI) for commercial tomato production were investigated at field sites in the southern Murray–Darling Basin region (SMDB). The soils at these sites were Vertosols (sites 1, 3, 4, and 5) and a Chromosol (site 2). At site 1, rapid transport and hydrolysis of urea occurred within the 0–90 cm soil layer of vegetable beds after a 6-mm fertigation of 30 kg urea-N/ha during cropping. Soil pH decreased by 0.2–0.4 units in individual 15-cm soil layers up to 90 cm within 12 days after the fertigation. A longer study at site 1 showed that there was severe acidification in topsoil and subsoil by the second consecutive year of SDI cropping. The rate of acidification was highest, at 52 kmol H+/ha.year, immediately beneath the dripline, in the 15–30 cm soil layer. Topsoil and subsoil acidification was also evident in vegetable beds at sites 2, 3, 4, and 5 after 2 consecutive years of tomato cropping using SDI. The results from the 5 sites indicated that acidification under SDI production may be widespread. A survey of 21 other sites in the SMDB under similar production showed that one-third of the sites had soil pH ≤6.0 in their 0–30 cm soil layer. Several soil types were individually represented at acid and alkaline pH levels, by 2 or more sites. This indicated that management practices influenced the change in soil pH for a given soil type. Altogether, the combined results of these studies strongly indicated that surface and subsoil acidification can occur in soils used for intensive SDI production. This may diminish their productivity in the long term.
