Summer Cover Crops

There is growing interest in the use of shortseason summer annual legumes or grasses as cover crops and green manures in vegetable production systems. Cover crops can provide a significant source of nitrogen (N) for subsequent crops; reduce erosion, runoff, and potential pollution of surface...

Application of Bicarbonate to High-Phosphorus Soils to Increase Plant-Available Phosphorus

Vegetable growers in the northeastern United States often have soils with P levels so high that fertilizer applications have environmentally detrimental effects. However, growers raise crops that require P fertilizer in cool soils regardless of soil P levels. A method to increase bioavailable P to...
