Soil Test Phosphorus Recovery from Livestock Manures Compared with Inorganic Fertilizer in Soil Incubations
Figure 1
% P Recovery Ratio (%PRR) for the two sources of manure (low-STP soil) and the five combination of source of manure and application rate (medium-STP soil) at the five incubation periods. Within each soil, means sharing the same letter are not significantly different.
