| Abstract/Contents: | "In the arid southwestern states of the US, many sources of irrigation water contain high levels of bicarbonates. As a result, soil pH can increase and soil permeability can be reduced. Injection of acid into the irrigation water is one possibility of neutralizing excess bicarbonates in irrigation water. A greenhouse study was conducted at New Mexico State University in Las Cruces to evaluate the effect of irrigation water mixed either with sulfuric acid or with CurativeTM on bicarbonate level in the drainage water and on the performance of perennial ryegrass (Lolium perenne (L.). Forty-eight containers measuring 12 cm in diameter and 12 cm in depth were filled with a loamy sand, seeded with perennial ryegrass, and irrigated with one of 12 different water qualities. The irrigation water contained about 250ppm bicarbonates levels and received one of two acidifying treatments applied at 4 rates. The highest rate was applied to adjust the pH to 6.5 (100% rate). The three other rates were 75, 50, and 25% of the highest rate. Treatments were replicated four times. Irrigation water was applied three times a week to maintain a constant container weight. Drainage water was collected from drip pans monthly and analyzed for bicarbonates, EC, pH, and SAR. Turfgrass quality, photographic images, and Normalized Difference Vegetation indices were collected bi-monthly. After three months, the level of bicarbonates in the drainage water was lower for sulfuric acid and for the two higher levels of Curative. At the end of the study, perennial ryegrass irrigated with potable water (control), with sodium bicarbonate alone, and with Curative at 50% and at 25% exhibited the higher visual quality, higher NDVI, and higher DGCI than all other treatments. Perennial ryegrass irrigated with potassium bicarbonate alone, potassium bicarbonate with sulfuric acid, and Curative at 75% performed poorest." |
