Abstract/Contents:The objectives of this experiment is to compare the stability of several root zone modification materials for sports turf to weathering and traffic. "There are many important factors in a desirable turfgrass root zone material namely: minimum compaction tendency, good water infiltration and percolation rates, adequate aeration for deep rooting, high cation exchange capacity (CEC) and adequate moisture retention. However, due to the heavy traffic that putting greens/tees and athletic fields receive, sand is the major component of root zone mix because it provides for good drainage, resists compaction and has good aeration. Soil and organic matter, thus, are used to a lesser degree in root zones primarily for the purpose of water and nutrient retention. Typically, sand root zones are amended with some form of organic matter. Peat is by far the most widely used organic amendment. In some situations locally available organic matter sources are used such as rice hulls, sewage sludge and lumber waste materials. Thought not routinely used, there are inorganic amendments: fired clay, colloidal phosphate, sintered fly ash, vermiculite, perlite, calcined clay/ diatomite and natural zeolites. The advantages of an organic amendment of sand such as peat are: increased water retention, increased nutrient retention (cations) and some pesticide binding (reduced pesticide leaching). On the down side, organic amendments will decompose in time and do not help retain much nitrate from leaching. Inorganic amendments can increase moisture retention to a limited degree, some will improve nutrient retention and some believed that they will breakdown over time as a result of weathering or traffic. Thus, there is a need for better understanding of the stability of inorganic amendments."
