The University of Delaware (UD) has rated soils in terms of the likelihood of profitable responses to additions of phosphorus (P) and potassium (K) from fertilizers, manures, and other soil amendments ...

A soil test for phosphorus represents an index of phosphorus availability to crops. A soil test needs to correlate to crop response in order to provide a useful index of crop response and any ...

Agricultural soil testing is critical to determining soil’s nutrient concentration and variability across your fields. It is ideal to test your fields’ soil at least every two to three years to inform ...

Long-term use of fertilizer and manure nutrients on the Delmarva Peninsula has led to an enrichment of agricultural soils with phosphorus (P). Consequently, many soils in Delaware are now considered ...

Soil contains an array of micronutrients and these form the building blocks for crops destined to be eaten, processed, or fed to livestock. It is vital for both consumers and industry that ...

Permafrost thaw can stimulate the release of soil carbon, triggering a positive carbon-climate feedback that may be mediated by changes in soil phosphorus (P) availability. A research team led by Prof ...

Innovative hydrochar technology led by Dr. Wei Guo at Beijing University of Technology and Dr. Xiaohui Liu at Ocean University of China transforms sewage sludge into smart phosphorus ...
