Manure Injection versus Broadcasting:
Effects on Phosphorus and Soil Loss
Melissa Miller, Former Research Assistant, Penn State University
Research conducted at a plot scale at Rock Springs PA looking at Phosphorus losses from Injecting Manure vs Broadcasting Manure.
There was a statistically significant reduction of Total Phosphorus loss and Dissolved Phosphorus loss in overland runoff resulting from Broadcast vs Injection application of manure. Particulate Phosphorus losses were not changed either way.
There were similar trends for Total Phosphorus and Dissolved Phosphorus losses through subsurface transport processes, but differences were not statistically significant due to subsurface flow variability.
