PHOSPHORUS MANAGEMENT Reduction of High Soil Test Phosphorus by Corn and Soybean Varieties
a significant relationship was found between soluble P loss in runoff and soil test P. Eghball and Gilley (2001) Soils with high levels of P can contribute to excess P in runoff and found that erosion was the most important factor in subsequently pollute the surface water. Excess P in the soil can be removed from the system by harvesting crops. The objectives of this loss of total and particula...
متن کاملPhosphorus 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 کاملIron Reduction and Phosphorus Release from Lake Sediments and Bt Horizon Soil: Incubation Studies to Explore Phosphorus Cycling
Sediment from two Georgia Piedmont impoundments and soil from the Georgia Piedmont Bt horizon were incubated with an easily consumable organic carbon substrate in an anaerobic environment to observe iron reduction and phosphorus release. 97% of porewater iron in the Bt horizon soil, 96% of porewater iron in Lake Lanier sediments, and 93% of porewater iron in Lake Oglethorpe sediments was reduce...

متن کاملUpdate on Phosphorus Uptake Phosphorus Uptake by Plants: From Soil to Cell
P is an important plant macronutrient, making up about 0.2% of a plant’s dry weight. It is a component of key molecules such as nucleic acids, phospholipids, and ATP, and, consequently, plants cannot grow without a reliable supply of this nutrient. Pi is also involved in controlling key enzyme reactions and in the regulation of metabolic pathways (Theodorou and Plaxton, 1993). After N, P is the...
