properties ( Vietor et al., 2007 ). Yet, additional research is needed to relate variation of soil physical properties to variation of turfgrass contributions to SOC during sod growth with and without CMB. Previous CENTURY model simulations of turfgrass
the experiment under the same watering regime as the substrates in the Horhizotrons. Physical properties (waterholding capacity, air space, bulk density) of organic matter substrates were determined using the NCSU Porometer™ ( Fontento et al., 1981
, hydrolyzable nitrogen, rapidly available phosphorus, rapidly available potassium, and organic matter) and soil physical properties (clay content and soil density) for the 0- to 25-cm soil layer were analyzed by the Tianjin Institute of Resource and
treatment effects. Soil health Cornell Soil Health Test. The Cornell Soil Health Test is a comprehensive analysis incorporating 12 different indicators that is designed to monitor changes in soil chemical, biological, and physical properties over the long
types suggests that VWC did influence the physical properties of the containers. We do not believe that fewer differences observed among containers used to produce geranium were a function of the difference in taxon, rather that it may be a result of the
Several studies have demonstrated the importance of physical, chemical and microbiological properties of compost on Agaricus bisporus growth and yield. However, to our knowledge, no experimentation has been conducted to determine the effect of storage on the properties of spawned compost. For this study, our objective was to compare the properties of spawned compost stored under different temperature regimes. The microflora and, the chemical and physical properties of prespawned compost pressed in shrink wrapped blocks were first determined and mushroom yield evaluated. Subsequently, composts that had been stored at 4°C, 15°C, 24°C for 10 and 14 days were analysed for the same variables. Our results showed that storage temperature affected some properties of compost but these changes did not affect mushroom yield.
. The dry weight of the roots was not recorded because part of the rooting system had penetrated into the layers used to simulate a green roof system at the bottom of each container. Substrate characteristics. The physical and chemical properties of the
6 mm in diameter) were found to be the most promising substitutes for rockwool thanks to their low cost and availability in addition to their excellent growth performance. However, the study concluded that, despite adequate soil physical properties
The present study was carried out during 1984/85 and 1985/86 to investigate the effect of four gibberellin acid concentrations (0.0, 25, 50, and 75 ppm) and five micronutrients treatments (no micro nutrients, copper, zinc, manganese and the three nutrients together) as well as the combination between them on the yield of Mindy banana plants and fruit physical and chemical properties. Under the conditions of this experiment the results indicated that the treatments contained gibberellin acid at 50 or 75 ppm and mixture of copper, zinc, and manganese significantly increased the yield of Mindy banana plants and improved fruit physical properties; however, fruit chemical constituents were somewhat inferior.
. Despite these measured differences, there were relatively few and minor differences in the nutrient concentration of the substrate. Furthermore, there were no measurable differences in sunflower growth or physical appearance (SPAD foliar chlorophyll), and
