“…Surfactant application ensures that soils are wettable to irrigation and will infiltrate quickly and uniformly. This fact confirms that more effective delivery of water to root zone can result in very significant reduction in water use or requirement (Brumbaugh and Petersen, 2001), and, consequently, increase irrigation efficiency (Kostka et al, 2007;Moore et al, 2010). As reported by Payero et al (2009) the values of IWUE based on dry matter ranged from 7.2 to 4.3 kg m -3 for corn under different irrigation levels, which was in agreement with our results.…”

Drought, and rising water and pumping costs dictate that continued production of corn (Zea mays L.) will be limited in future years if effective water conservation strategies are not established. This study was conducted to evaluate the effect of irrigation regimes in conjunction with surfactant treatments on field corn grain yield (GY), total dry matter (TDM) production, and irrigation water use efficiencies (IWUE) based on GY and TDM in a distinct Mediterranean climate, at Spadra Ranch in Pomona, CA, for 2 yr (2008 and 2009). The field experiment was set up in a split plot design with four replications where irrigation regimes (I40: 40%, I60: 60%, I80: 80%, and I100: 100% of the estimated evapotranspiration) was the main plot and application of surfactant (water treated with surfactant and no surfactant application) was assigned to the subplot. The results showed a stepwise reduction in TDM and GY in treatments both with and without surfactant as water deficit increased. However, surfactant application at any irrigation level resulted in higher GY and TDM compared to no‐surfactant treatments. Irrigation water use efficiency based on TDM and GY was the highest in I40 and the lowest in full irrigation (I100) conditions. By application of surfactant in irrigation water, both IWUE and GY increased. Surfactant application increased irrigation costs by 4.7%; however, it increased profit by 19.75%. Economic evaluation showed that the grain yield increment could compensate surfactant price and consequently the same profit achieved with applying 40% less water plus surfactant compared with 100% crop evapotranspiration with no surfactant application. In a Mediterranean climate and under limited irrigation conditions, corn could be cultivated with acceptable yields by application of surfactant.

“…Heijs et al, 1996;Lichner et al, 2011;Ritsema et al, 1997). Water repellency in soil and the associated preferential flow are like "barriers" and "leaks" in the soil plumbing system, respectively (Moore et al, 2010). Water repellency may intensely affect water and solute movement at the field-scale, a process which has often been underestimated (Aamlid et al, 2009;Bauters et al, 2000;Orfánus et al, 2016;Ritsema and Dekker, 1995;Wessolek et al, 2009).…”

Soil water content and actual water repellency were assessed for soil profiles at two sites in a bare and grasscovered plot of a sand pasture, to investigate the impact of the grass removal on both properties. The soil of the plots was sampled six times in vertical transects to a depth of 33 cm between 23 May and 7 October 2002. On each sampling date the soil water contents were measured and the persistence of actual water repellency was determined of field-moist samples. Considerably higher soil water contents were found in the bare versus the grass-covered plots. These alterations are caused by differences between evaporation and transpiration rates across the plots. Noteworthy are the often excessive differences in soil water content at depths of 10 to 30 cm between the bare and grass-covered plots. These differences are a consequence of water uptake by the roots in the grass-covered plots. The water storage in the upper 19 cm of the bare soil was at least two times greater than in the grass-covered soil during dry periods. A major part of the soil profile in the grass-covered plots exhibited extreme water repellency to a depth of 19 cm on all sampling dates, while the soil profile of the bare plots was completely wettable on eight of the twelve sampling dates. Significant differences in persistence of actual water repellency were found between the grass-covered and bare plots.

“…Application of wetting agents (surfactants) has been the most effective remediation practice, probably because it is focused on altering the hydrophobic organic matter properties and surface tension of water. However, this approach is costly and only renders short-term positive effectiveness with repeated applications needed to maintain hydrophilic conditions (Moore et al, 2010;M€ uller and Deurer, 2011). Biological methods involving culturing microorganisms capable of degrading wax in soil is another remediation approach that concentrates on altering the nature of the organic matter associated with SWR and it has been shown to be effective at the laboratory scale (M€ uller and Deurer, 2011;Roper, 2004).…”

Organic coatings on sand particles can cause soil water repellency (SWR) where a soil does not spontaneously wet; this leads to challenges in water management and crop production. In laboratory studies, we evaluated a novel approach using direct application of 10 enzymes at three (low, medium, high) dosages to remediate SWR on two sand turfgrass soils in a 3-day incubation study and a second study at high dosage with 1-day incubation. A soil:solution ratio of 1:1 (10 g soil and 10 mL solution) was used and a deionized water control included. For Soil 7, a very strongly hydrophobic soil from a localized dry spot turfgrass area with a water drop penetration time (WDPT) of 7440 seconds (untreated) and 332 to 338 seconds (water-treated), the high dosage rates of laccase, chitinase, and protease at 1 and 3 days incubation resulted in WDPT of less than 60 seconds (i.e., hydrophilic soil). Pectinase exhibited similar results only in the 3-day incubation study. On the strongly hydrophobic Soil 21 (WDPT of 655 seconds untreated; 94 to 133 water-treated) from the dry area of a fairy ring-affected area on a turfgrass site, high dosages of chitinase, laccase, pectinase, and protease reduced WDPT to less than 60 seconds in both studies; and medium dosage rates were also effective for all but protease in the 3-day incubation study. Each of the four most effective enzymes for reducing WDPT, noted previously, demonstrated a significant exponential or logarithmic relationship between decreasing WDPT and increasing enzyme dosage. Further studies in field situations will be required to determine enzyme effectiveness on SWR and water management.
