Phosphorus retention capacity in red ferralitic soil.
In this study the main physical-chemical characteristics of red ferralitic soil to use as substrate in subsurface wetlands was determined. The P-removal was evaluated in a short-term isotherm batch experiment and in a column percolation experiment. The acid characteristic and high content of iron minerals in the red ferralitic soil facilitated the phosphorus removal. Also the sorption isotherms...
متن کاملPhosphorus Retention in Sediments
Phosphate is usually the most important growth limiting nutrient in aquatic environments-The availability of P is the result of external load and retention in the sediments. This latter is the result of a number of transport, microbial and chemical processes. 'The role of P in the productivity in systems and in the eutrophication process has initiated a large number of studies to the behaviour ...
متن کاملDissolved Phosphorus Retention in Buffer Strips: Influence of Slope and Soil Type.
Phosphorus (P) contributes to eutrophication of surface waters and buffer strips may be implemented to reduce its transfer from agricultural sources to watercourses. This study was conducted to test the hypothesis that soil type and slope influence the retention of dissolved organic P and inorganic orthophosphate in agricultural runoff in 2-m-wide buffer strip soils. A solution, comprised of di...
متن کاملAn Assessment of the Phosphorus Retention Capacity of Wetlands in the Painter Creek Watershed, Minnesota, Usa
Lake Minnetonka, located in southeastern Minnesota, U.S.A., is currently experiencing increased eutrophication due to excessive phosphorus (P) loading in runoff from agriculture and urban areas. This phenomenon has been exacerbated by the isolation of wetlands in the surrounding watershed from the surface water drainage network. In order to determine if rerouting surface water through these wet...
متن کاملStudy on the Effect of Different Modified Zeolite to Phosphorus Activation in Red Soil
The activation of soil-fixed phosphorus is a long-term concern in soil science. In order to enhance the activation effect to soil-fixed phosphorus in red soil, different modified zeolite, through physical, chemical method and the associated both physics and chemistry, was used in this paper. The results showed as following: 1) the activated ability to soil-fixed phosphorus in red soil for modif...
