چکیده
Wetting agents can be used to increase infiltration rates into hydrophobic (water repellent) soils. A field test was conducted on a soil classified as Tujunga stony sandy loam, which was found to be extremely hydrophobic to learn more about the effectiveness of wetting agents. The area is located near Fontana. The land had been farmed in small grain crops years ago and then was used as a hog ranch, but it has been idle for about eight years. The test plots were l0-foot-square basins with soil borders. Two wetting agents (designated as products A and P) were used in the study at dilutions of 1 part wetting agent to 650, 1300, 2000, and 4000 parts of water. Water was pumped from a water truck into each basin to a depth of four inches. As the water was being applied to the basin, enough wetting agent was added to the flow stream to produce the desired dilution. Each treatment was replicated three times and six basins were used as checks and received only water.

California is suffering from a serious drought and the future of turfgrass and other landscape plants has never been more uncertain. Use of drought tolerant plant species should be at the forefront of water conservation management plans for golf courses and other landscapes. Warm-season or C4 grasses are better adapted to warmer, drier climates and use at least 20% less water compared to cool-s...

متن کاملThe Microbiology of Turfgrass Soils
Most turfgrass managers do not have a strong understanding of turfgrass soils, particularly the biological aspects. Certainly most know that living things, such as worms and insects can reside in soil, but they’re not sure where in the soil they live or what they live on. In fact, it might be safe to assume that most turfgrass managers consider soil to be a mysterious world below the turfgrass ...
