Physical Properties of Three Sand Size Classes Amended with Inorganic Materials or Sphagnum Peat Moss for Putting Green Rootzones

Abstract

ABSTRACTpared with unamended sand (McCoy, 1992 (Davis et al., 1970;Waddington et al., 1974). By contrast, h Ϫ1 , probably because of the very uniform sands. On the basis of Van Bavel et al. (1978) data interpretation difficult. Therefore, the overall objective of this study was to evaluate several commercially available IAs for potential use in newly constructed putting green rootzones.

Zeolite Farming: A Sustainable Agricultural Prospective

“…The zeolite is found in Saline, Alkaline lakes; deep sea sediments; low temperature open hydrologic systems; burial digenesis and geothermalhydrothermal system (Hay-Geologic occurrence of zeolites and some associated minerals, 1986). Zeolites have good water holding capacity and soil drainage (Bigelow et al, 2004;Colombani et al, 2015;Huang and Petrovic 1994). Some of the important applications of zeolites are in agriculture, water treatment, gas adsorption, industrial gas separation, aquaculture, animal husbandry, ion exchange and also for order control.…”

Water Storage in Putting Greens Constructed with United States Golf Association and Airfield Systems Designs

“…Since the matric and gravitational potentials of the root zone water are in equilibrium after drainage ( Jury and Horton, 2004), the total water stored in the profi le, volume per area (D, in meters), can be calculated as [1] in which h (in meters) is water tension, θ(h) (in cubic meters per cubic meter) is a function generating volumetric water content from water tension, h b is the water tension at the bottom of the root zone profi le, and z rz is the depth of the root zone. Because of the shapes of the θ(h) relationships for root zone mixtures commonly used in construction of putting greens (e.g., Chong et al, 2002;Bigelow et al, 2004) . It is common knowledge that inclusion of a gravel drainage layer in a putting green infl uences the amount of water stored in the root zone during and after drainage, but the manner in which capillary and hydraulic properties of gravel interact to infl uence water tension along with the associated retention is diffi cult to predict.…”

Evaluation of the physical properties of water treatment residue for use as a soil substitute compared with decomposed granite soil

“…The water retention curve for the WTR was similar to that of porous inorganic amendments such as diatomaceous earth and calcined clay (Bigelow et al 2004). The WTR has many internal pores created during the flocculation process (Moodley and Hughes 2006), resulting in a water retention curve similar to that of porous inorganic amendments.…”

“…The total porosity was calculated from the Bd and particle density (Dane and Topp 2002). The amount of water retained at )4 kPa indicated the capillary porosity (Bigelow et al 2004). Macro porosity was calculated by subtracting the water content at )4 kPa from the total porosity.…”
