Researchers have demonstrated that phosphorus compounds appear to provide a chemical fire extinguishment mechanism, and in fact some appear to be highly effective flame extinguishants. Much reported work has been performed on dimethyl methyl phosphonate (DMMP) and related compounds …

Soils - Part 6: Phosphorus and Potassium in the Soil

At high soil pH, most phosphorus is in the form of calcium compounds. At low or acid pH, phosphorus is combined with iron and aluminum compounds. Maximum phosphorus availability occurs at a soil pH between 6.5 to 7.0. This is why one of the most important benefits of acid soils is improving phosphorus availability.
