“…Water applied per SURGE event and total water applied with SURGE in season was reduced by 22 and 24%, respectively, as compared with CONV (Table 3). Others reported that SURGE on clay-textured soils reduced total irrigation water use 31 to 80% (Izuno et al, 1985;Testezlaf et al, 1987;Musick et al, 1987;Rodriguez et al, 2004). Additionally, linear regression analysis indicated that 98% of the variability in the percent reduction in irrigation water applied by SURGE was a function of furrow length (Fig.…”

“…Others noted that on clay-textured soils, grain yields were either not affected by SURGE or were reduced up to 12% (Onder, 1994;Kanber et al, 2001;Goldhamer et al, 1987;Musick et al, 1987). Many researchers, however, report that SURGE on clay-textured soils increased IWUE up to 19% relative to the control (Izuno and Podmore, 1986;Unlu et al, 2007;Okasha et al, 2013).…”

“…Once the water has reached the end of the furrow, a soak phase is utilized to reduce runoff by using shorter "on" cycles, allowing the field to be irrigated to the desired depth. The intermittent application of water with SURGE on clay-textured soils reduces infiltration and deep percolation losses, increases furrow advance time, decreases total irrigation water applied, and improves irrigation application efficiency (Goldhamer et al, 1986;Israeli, 1988;Musick et al, 1987;Eid et al, 1999;Testezlaf et al, 1987;Bishop et al, 1981;Izuno et al, 1985). Surge flow irrigation has not been evaluated on clay-textured soils in the Mid-South.…”

The Mississippi River Valley Alluvial Aquifer is declining precipitously due to irrigation withdrawal for row crop production. Currently, 25% of the soybean (Glycine max L.) acres in the Mid-South are planted on clay-textured soils and furrow-irrigated using conventional continuous flow (CONV), the least efficient irrigation delivery system. The objective of this research was to determine the effect of surge irrigation (SURGE) on amount of water applied, soybean grain yield, irrigation water use efficiency (IWUE), and net return above irrigation costs when implemented on clay-textured soils. The research was conducted during the 2013 through 2015 growing seasons in Stoneville, MS and consisted of paired fields, with the same cultivar, soil texture, planting date, and management practices used on both sites. Paired fields were randomly assigned as SURGE or CONV. Water applied to each field was monitored with flowmeters, and irrigations were initiated based on soil moisture sensor thresholds. Relative to CONV, SURGE reduced the amount of water applied per irrigation event by 22% and total water applied in season by 24% (P £ 0.0349). Soybean grain yield averaged 66 bu/acre and was not different between delivery systems (P = 0.7711), but SURGE increased IWUE by 29% compared with CONV (P = 0.0076). Net return above irrigation cost was not different between CONV and SURGE, regardless of diesel price or pumping depth (P ³ 0.1149). Results from this research indicate that soybean producers in the Mid-South and other regions that irrigate using lay-flat polyethylene tubing can adopt SURGE for soybean on clay-textured soils without adversely affecting yield or on-farm profitability while concurrently decreasing the demand on depleted groundwater resources.

“…Reduced water use in IWM at the field scale was equivalent to values observed for individual IWM practices at the meso-plot scale. For example, relative to CONV, CHS reduced irrigation water use in soybean 17% (Krutz 2016), and surge flow reduced irrigation water use in soybean from 24% to 80% relative to the control (Izuno et al, 1985;Musick et al, 1987;Testezlaf et al, 1987;Rodriguez et al, 2004). Additionally, sensor-based scheduling reduced the number of irrigations applied to soybean 50% compared with CONV (Krutz et al, 2014.…”

“…Once the water has advanced to the end of the furrow, runoff is reduced using short cycles in a cutback mode, for example, a soak phase, allowing the field to be irrigated to the desired depth. The intermittent application of water with SURGE increases furrow advance time, reduces deep-percolation losses, decreases total irrigation water applied, and improves irrigation application efficiency (Bishop et al, 1981;Izuno et al, 1985;Goldhamer et al, 1987b;Musick et al, 1987;Testezlaf et al, 1987;Israeli, 1988;Eid et al, 1999).…”

Withdrawal for agricultural uses has decreased water levels in the Mississippi Alluvial River Valley aquifer (MARVA), and Mississippi state regulators have responded by requiring withdrawal permits, establishing permitted withdrawal limits, and instituting required minimum levels of irrigation water use efficiency (IWUE) practices. The objective of this research was to determine the effect of integrating irrigation water management (IWM) practices-including computerized hole selection (CHS), surge flow irrigation (SURGE), and sensor-based irrigation scheduling-on irrigation water use, soybean grain yield, IWUE, and net returns above irrigation costs at the production scale. The experiment was conducted in the Prairie region of Arkansas and the Delta region of Arkansas and Mississippi from 2013 through 2015. The research consisted of 20 paired fields, with the same cultivar, soil type, planting date, and management practices. One field was randomly assigned as the control (conventional, CONV) and the other was instrumented with CHS, SURGE, and soil moisture sensors, that is, IWM. Flowmeters were installed in the inlets to both fields, and the farmers provided yield data. Soybean grain yield averaged 69.0 bu/acre and did not differ between CONV and IWM (P = 0.6703). Relative to CONV, IWM reduced water use 21% (P = 0.0198) and increased IWUE 36% (P = 0.0.0194). Net returns for soybean production above irrigation costs were not different between CONV and IWM, even when pumping depth ranged from 18 ft to 400 ft and diesel costs ranged from $1.60/gal to $3.70/gal (P ³ 0.5376). These results demonstrate that implementation of integrated IWM at the production scale reduces the demand on depleted groundwater resources without adversely affecting soybean grain yield or on-farm profitability.

Furrow‐irrigation application efficiency in mid‐southern U.S. conservation tillage systems

et al. 2020

Approximately 80% of mid‐southern U.S. irrigation requirements are supplied through gravity flow delivery systems with inherently low application efficiency. This research was conducted to determine whether the efficiency of furrow‐irrigation systems could be manipulated through conservation tillage systems. Three experiments were conducted near Stoneville, MS, on a Dubbs silt loam to determine the effects of reducing tillage and increasing ground cover residues on irrigation application efficiency and irrigation water use efficiency. In Exp. 1, transitioning from conventional tillage to a conservation tillage system had no adverse effect on irrigation application efficiency and irrigation water use efficiency when subsoiling was included. For Exp. 2, replacing subsoiling with a cereal rye (Secale cereale L.) or tillage radish (Raphanus sativus L.) cover crop in a conservation tillage system either had no effect or reduced irrigation application efficiency and irrigation water use efficiency up to 10%. In Exp. 3, independent of cover crop, reducing tillage to only furrow creation had no adverse effect on irrigation application efficiency or irrigation water use efficiency relative to a conservation tillage system with subsoiling. Conservation tillage systems that include subsoiling maximize irrigation application efficiency and irrigation water use efficiency while minimizing adverse effects on yield and net returns relative to conservation tillage systems that further reduce tillage and/or increase ground coverage with cover crops. Our data indicate that soybean [Glycine max (L.) Merr.] producers in the mid‐southern United States maximize furrow‐irrigation functionality, yield, and profitability while minimizing risk by transitioning from a conventional tillage system to a conservation tillage system with subsoiling.
