1. Soil Phosphorus Fractions and Legacy after Long-term Fertilizer Placement in a Corn-Soybean RotationPhosphorus (P) fertilizer placement can affect plant P uptake during the growing season, however, the long-term interaction of placement and plant root P uptake can also affect soil P pools. The objective of this study was to evaluate the influence of long-term P fertilizer placement on soil P pools (labile, moderately labile and non-labile) and legacy soil P accumulation under a corn (Zea mays) -soybean (Glycine max (L.) Merr.) rotation. A field study was conducted for ten years from 2006-... M. Coelho, D. Ruiz diaz, G. Hettiarachchi, F. Hansel |
2. Root Growth and Phosphorus Uptake Affected by Fertilizer Management in Soybean and WheatPlant root growth patterns can be affected by nutrient and water availability. The objective of this study was to assess the effect of phosphorus (P) fertilizer management on soybean (Glycine max. L) and winter wheat (Triticum aestivum L.) root system growth and macro and micronutrients uptake. Two greenhouse studies were carried out at Kansas State University, Manhattan, Kansas under controlled environment. The experimental design... F. Hansel, D. Diaz |
3. Soybean Yield Response to P Fertilizer Placement as Affected by Soil Parameters: A ReviewIn the last decades, several studies were conducted to evaluate more efficient P fertilizer management with emphasis on placement. Many of these studies report contrasting results, suggesting that a general recommendation may not be appropriate and specific factors of soils, crops, and weather should be considered. A literature search was completed using Google Scholar, and published papers that met our selection criteria included 62 experiments, with 95 site-years. Approximately 9.8% of the studies... F.
