Nutrient Leaching When Soil Is Part of Plant Growth Media
Soils can serve as sorbents for phosphorus (P), negating the need for artificial sorbents. The purpose of this study was to compare soils with different properties for their effect on nutrient levels in effluent. Four soils were mixed with sand and packed into columns 0.5 m long, with or without compost on the surface. Infiltration and effluent concentrations were measured before and after grow...
متن کاملA Targeted Management of the Nutrient Solution in a Soilless Tomato Crop According to Plant Needs
The adoption of closed soilless systems is useful in minimizing the environmental impact of the greenhouse crops. Instead, a significant problem in closed soilless systems is represented by the accumulation of ions in the recycled nutrient solution (NS), in particular the unabsorbed or poorly absorbed ones. To overcome such problem, we: (1) studied the effect of several values of the electrical...
متن کاملIncorporating Evaluation into Media Campaign Design
Research indicates that one in five women will be the victim of sexual violence in her lifetime (Tjaden & Thoennes 1998). Throughout the United States there exists an infrastructure of prevention programs and support networks for victims of sexual violence; however, funding and utilization are a constant struggle. Organizations have tried to maximize these scarce resources by using media campai...
متن کاملElectrical Conductivity of Nutrient Solution, Plant Growth and Fruit Quality of Soilless Grown Tomato
Tomato plants (cv. Naomi) were grown until the 8 cluster in a greenhouse during Aug. 1998 – Jan. 1999 using a closed sub-irrigated soilless system. Plants were raised in pots (10 L) filled with peat and pomice (1:2 v:v) substrate. Forty days after transplanting 3 nutrient solutions (NS) with electrical conductivity (EC) of 2, 4, and 6 dS/m were applied to the plants. The ECs were achieved by pr...
متن کاملInfluences of clinoptilolite and surfactant-modified clinoptilolite zeolite on nitrate leaching and plant growth.
The increasing demands for environmental protection and sustainable food production require an increase in the use of natural and non-toxic materials for agriculture. In this study, the feasibility of using surfactant-modified zeolite (SMZ) in comparison with zeolite clinoptilolite (Cp) application to reduce nitrate leaching and enhance crop growth was investigated. The effects of size (millime...
