1. Fertilizer management and cover crop effects on phosphorus use efficiency, environmental efficiency and crop yieldPhosphorus loss from agricultural production is a significant contributor to the degradation and contamination of surface and ground waters. To help protect these waters, it is vital to maximize agronomic and environmental efficiency of phosphorus in the cropping system. The objective of this study was to quantify the effects of cover crops and different phosphorus fertilizer management practices on nutrient use efficiency, environmental efficiency and yield in a no-tillage corn-soybean rotation....

2. Water Use Efficiency and Soil Changes After Long-term Crop Rotation Under Limited IrrigationLong-term crop rotation intensity and diversity can affect key soil properties. In semi-arid regions, the combined factors of rotation and soil properties may also affect the overall water use efficiency from either limited irrigation or rainfall. The objective of this study was to evaluate changes in soil properties, and water use efficiency of corn grown under different rotation intensity and diversity and limited/supplemental irrigation. A field experiment was conducted over seven years in... P. Garcia, D. Ruiz diaz, B. Olson, A. Tonon rosa, K. Roozeboom |
