Turfgrass Establishment and “Grow-in”
Published in L.B. (Bert) McCarty, Golf Turf Management, 2018
Low spots and poor drainage areas—Low spots that drain poorly invariably happen as settling occurs in fairways, tees, and collars. In most cases, low spots can be corrected by additional sand topdressing. If it is too severe, sod in these areas should be removed, the areas brought up to grade with soil or sand, and then resodded. Also, despite the best drawings, additional drainage will be needed in certain areas as settling occurs or wet springs surface. Sand, gravel pipe, and outlets will be needed to correct this. Other needed items are a backhoe and trencher and hand labor to install this equipment. Equipment rental may be an option for this equipment.

The results suggested that the chosen treatments, Bermuda grass sod, tall fescue seed, and white clover seed, would be able to grow in contaminated soil. Sod may be a useful way to establish vegetation rapidly using mature plants rather than seedlings. However, it is important to monitor rooting from the sod into the contaminated soil during the field study period.

Recently, some studies have been carried out on the effects of stress on antioxidant enzyme activity and lipid peroxidation in the plant. However, few studies are focusing on lipid peroxidation and antioxidant responses of Microcoleus vaginatus with the aid of attapulgite-based nanocomposites to wind stress. Thus, this study tried to elucidate the effectiveness and anti-wind erosion ability of Microcoleus vaginatus with the aid of attapulgite-based nanocomposites, the changes in ROS, MDA, SOD, CAT, POD, GSH and the surface character of the soil were analysed. This study aims to find a method that can act as bioindicators for investigating wind erosion in arid and semiarid areas in the future, for offering a method to prevent desertification and provide a valuable measure for sustainable development of the environment.

Depending on the condition of the affected site, burned areas require urgent and long-term restoration strategies to prevent secondary damage such as landslides and sediment runoff in burned areas. Urgent restoration methods such as hillside sod and seed‐spraying treatments in burned areas have been determined to be useful for preventing soil erosion (Ryu et al. 2017). Much of the 137Cs inventory is in the top layers of the soil due to the litter recycling described, and burning of the surface duff layers will affect radionuclide cycling, as well as altering the forest ecosystem. The effects of fire depend on burn severity, with light surface burns at cooler temperatures being much different from severe crown fires. Enhanced leaching of 137Cs will likely occur following a fire, but this leaching may only be to the rooting zone where surviving trees or new plants will access it (Ryu et al. 2017). Planting of trees or shrubs is a long-term option to help fix the contaminants on the site.

The amount of soil removal by cutting of sod show variability depending on the cutting depth of sod strips and soil type management applications such as using plastic netting material and rooting intensity of crops and soil amendments [1]. Results presented in Figure 6 show that compost incorporation to the soil (PASC or PASC + BC) more significantly (unpaired t test: p < .0001) reduced the soil removal at the sod harvest compared to the BC and soil control. Soil removal rates were also improved by BC application, but the difference was insignificant (unpaired t test: p = .5558 ≥ α = 0.05) compared to the unamended soil treatment.
