Improving Phosphorus Efficiency in Crops with Focus on Purple Acid Phosphatase: Potentials and Perspective
Low-phosphorus (P) stress as a key factor limiting plant growth and production is common in most agricultural soils. Most of the soil-applied phosphate will be rapidly immobilized and most of annually applied phosphate fertilizers are fixed in the soil in organic forms by adsorption, sedimentation and transformation. However, excess P application may lead to contamination of water sources by en...
متن کاملVariable-rate Phosphorus Fertilization: On-farm Research Methods and Evaluation for Corn and Soybean
This study adapted precision agriculture technologies to commonly used field-scale strip trials and compared fixed and variable phosphorus (P) fertilization for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.]. Differential global positioning receivers, yield monitors, and grid soil sampling were used. Variablerate fertilization reduced considerably the total amount of P fertilizer appli...
متن کاملOverexpressing AtPAP15 enhances phosphorus efficiency in soybean.
Low phosphorus (P) availability is a major constraint to crop growth and production, including soybean (Glycine max), on a global scale. However, 50% to 80% of the total P in agricultural soils exists as organic phosphate, which is unavailable to plants unless hydrolyzed to release inorganic phosphate. One strategy for improving crop P nutrition is the enhanced activity of acid phosphatases (AP...
متن کاملPHOSPHORUS 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 کاملResponse of Seed and Oil Yields and Phosphorus Agronomic Efficiency of Soybean to Simultaneous Placement of Nitrogen with Phosphorus under Drought Stress
In order to study yield, yield components and agronomic efficiency of phosphorus in soybean affected by simultaneous placement of nitrogen with phosphorus, an experiment was carried out under moisture stress conditions, at Agricultural Research Station of Bu Ali Sina University, Hamedan, Iran in 2017 in a factorial split plot based on randomized complete block design with three replications. Th...
