Soil Test Phosphorus Recovery from Livestock Manures Compared with Inorganic Fertilizer in Soil Incubations

Table 4

Soil Test P (ppm) values for the control, as well as the fertilizer, the dairy manure, and the hen manure sources and their application rates at the five incubation times. The shown values are averages of three replications.
