| Abstract/Contents: | "The use of soil surfactants has become an established practice in turfgrass management. A reduction in irrigation water inputs, however, has seldom been quantified. The purpose of this one-season field study was to apply soil surfactants to mature 12 mm fairway height creeping bentgrass (Agrostis stolonifera 'L-93') on a clay loam rootzone and measure the amount and frequency of irrigation water needed to maintain a daily volumetric water content (VWC) threshold of 35% during an imposed dry-down period. Treatments of soil surfactants and untreated controls were arranged as a RCBD with three replications, and individual plot size was 0.9m Œ 1.5m. OARS HS (15.9 L product·ha-1) and PBS150 (15.9 L product·ha-1) were applied twice (27 Apr, 26 May 2016) or three times (30 Mar, 27 Apr, 26 May 2016) prior to an imposed dry-down period (8 Jun - 8 Aug 2016). During dry-down, VWC was measured daily at 0900 am in each plot using a 7.6cm TDR (Spectrum FieldScout 300). If VWC measured ≤ 25%, the plot was irrigated until it reached 35%. Compared to maintaining the untreated plots at 35% VWC daily, plots treated with two applications of PBS150 or OARS HS resulted in a mean of 25.0 or 26.5% reduction in water applied, and plots treated with three applications of PBS 150 or OARS HS resulted in a mean of 36.3 or 39.4% reduction in water applied. Furthermore, untreated plots at 35% VWC had to be watered 41 days while plots treated with OARS HS or PBS150 required water on only 14 and 13 days of the dry-down period, respectively. Use of soil surfactants in this field trial resulted in a statistically significant (P < 0.05) savings in both amount and frequency of irrigation water inputs while maintaining acceptable turfgrass quality." |
