Scarcity of fresh high-quality water has heightened the importance of wastewater reuse primarily in dry regions together with improving its efficient use by implementing the Subsurface Drip Irrigation (SDI) method. Sustainable effluent reuse combines soil and plant aspects, along with the maintainability of the application system. In this study, field experiments were conducted for two years on the commercial farm of Revivim and Mashabay-Sade farm (RMF) southeast of the City of Beer-Sheva, Israel. The purpose was to examine the response of alfalfa (Medicago sativa) as a perennial model crop to secondary domestic effluent application by means of a SDI system as compared with conventional overhead sprinkler irrigation. Emitters were installed at different depths and spacing. Similar amounts of effluent were applied to all plots during the experimental period. The results indicated that in all SDI treatments, the alfalfa yields were 11% to 25% higher than the ones obtained under sprinkler irrigated plots, besides the one in which the drip laterals were 200 cm apart. The average Water Use Efficiency (WUE) was better in all SDI treatments in comparison with the sprinkler irrigated plots. An economic assessment reveals the dependence of the net profit on the emitters' installation geometry, combined with the return for alfalfa in the market.

HighlightsCrop coefficients for SDI scheduling for grain corn should be reduced by ~10% from those used for sprinkler irrigation.FAO 56 methods to calculate crop coefficients for surface drip irrigation under full-cover plastic mulch were applicable to SDI.A recent drought-resistant corn hybrid appeared to begin rapid leaf area development about 10 days earlier than older hybrids.A recent drought-resistant corn hybrid appeared to finish earlier than older hybrids by about 15 days.Abstract. Subsurface drip irrigation (SDI) has become an important irrigation application method in the U.S. Southern High Plains where pan evaporation exceeds 2,400 mm per year. Early research comparing SDI with spray sprinklers showed that SDI was over-applied when scheduling irrigations using crop coefficients developed using sprinkler irrigation. Thus, crop coefficients developed using SDI may be smaller than those developed using sprinkler irrigation. Grain corn was grown for two years on large, precision weighing lysimeters at Bushland, Texas, with two lysimeters irrigated by SDI and two by mid-elevation spray (MESA) irrigation. Data used in this study were for fields irrigated to replenish soil water in the top 1.5 m of the soil to field capacity, as indicated by weekly neutron probe readings (100% replenishment). Crop coefficients developed for SDI (Kc_SDI) were compared with those developed for MESA (Kc_MESA) using ASCE standardized reference ET equations. The value of Kc_SDI ranged from 0.83 to 0.89 of Kc_MESA for the two years. Values of Kc_SDI remained consistently less than Kc_MESA even after maximum leaf area index was reached, indicating that considerable evaporative loss from the soil surface occurred with MESA irrigation even after full canopy cover. When we shortened the initial period after planting from 30 to 20 d and followed FAO 56 recommendations for surface drip irrigation under full-cover plastic mulch, we calculated basal Kc (Kcb) values (ETo basis) that were reasonably close to our Kc values for SDI for the crop development and early mid-season periods but were greater than our data for the later mid-season and late season periods.

Spatial patterns of lettuce big-vein (LBV) incidence under furrow, sprinkler, and subsurface drip irrigation systems were determined. Because LBV pathogen is a virus and is vectored by the soilborne chytrid Olpidium brassicae, different irrigation systems likely affect the movement of the vector and were hypothesized to result in different distribution patterns and levels of the disease. Lettuce plants were mapped by recording the location of each LBV-infected or healthy plant in arbitrarily selected plots of sizes 16 by 30, 20 by 30, and 18 by 50 m in Salinas, Gonzales, and Santa Maria in California. Data were arrayed into different quadrat sizes by rearrangement, and disease incidence was calculated for each quadrat. Frequency distribution analysis and spatial autocorrelation analyses were performed on this data. LBV incidence was aggregated in all furrow-irrigated fields, four of five subsurface drip-irrigated fields, and two of three sprinkler-irrigated fields. The remaining fields had a random distribution. As the quadrat size increased, index of aggregation decreased, and vice versa. In fields under sprinkler irrigation, regardless of whether the spatial pattern of LBV was random or aggregated, no directional orientation occurred. However, under furrow or subsurface drip irrigation, the aggregation mostly occurred across the rows. Although irrigation type influenced LBV distribution pattern and incidence in lettuce fields, the differential effects of irrigation type on vector O. brassicae could not be discerned in this study. The sprinkler irrigation practiced in lettuce production until thinning may influence the vector distribution and the subsequent irrigation methods adapted for the remainder of the season in individual fields may play a significant role in disease incidence.

A critical objective for any wastewater reuse programme is to minimise health and environmental hazard. When applying wastewater to soil–plant systems, it is to be noted that the passage of water through the soil considerably reduces the number of microorganisms carried by the reclaimed wastewater. Factors that affect survival include number and type of microorganisms, soil organic matter content, temperature, moisture, pH, rainfall, sunlight, protection provided by foliage and antagonism by soil microflora. The purpose of this work was to examine the behaviour of fecal pollution indicators in a soil irrigated with treated wastewater under onsurface and subsurface drip irrigation. The experiment was conducted in a vineyard located at a commercial farm near the City of Arad (Israel). Wastewater and soil samples were monitored during the irrigation period and examined for fecal coliforms, somatic and F+ coliphages and helminth eggs. Physico-chemical parameters were controlled in order to determine their relationship with removal of microorganisms. The results showed high reduction of the concentration of microorganisms when wastewater moves through the soil; and a good correlation between the reduction of fecal pollution indicators and moisture content, organic matter concentration and pH. The application of secondary treated domestic wastewater in this specific soil and under these irrigation systems affect the survival of microorganisms, thus reducing the health and environmental risk.
