Spreading Manure

Caption

The method of animal manure application can influence the availability of nutrients and estrogens to runoff water. Several Penn State studies have shown the potential benefits of shallow disk injection (shown here) for reducing phosphorus and nitrate transport in surface runoff compared to surface broadcasting. Just published research demonstrated significantly reduced estrogen transport in runoff from shallow disk injection plots relative to surface broadcast plots. The inset photo shows injectors.
