Here’s another field. A well-maintained pasture with healthy grasses is a nutritious and relatively inexpensive feed source for horses. Adding lime encourages the activity of soil bacteria, so valuable nutrients such as nitrogen, phosphorus, and sulfur can be released. ...
Economic and social pressures toward measures that may load forest soils with phosphorus are increasing, however. Although forest fertilization is in its infancy in the western United States, and nitrogen is presently used almost exclusively, our studies suggest that trees on certain forest soils ...
Tomatoes remain one of the most popular and widely grown vegetable crops. However, their growth requires a high supplement of nitrogen-phosphorus-potassium (NPK) fertilizer. The effectiveness...doi:10.1080/00103624.2018.1427256Hai-tao, ZhaoYu-Feng, Wu...
