Fryers are fed a higher protein diet which results in a higher nitrogen content in the litter including the added benefit of mulch. Raw, pure chicken manure products come from laying operations which feed a much lower protein food resulting in a lower nitrogen analysis. It is true, pure chicken manure will burn young and tender plants.
Raw manure releases nitrogen into the soil too rapidly, causing burning.
In SUP'R Green, the elements are suspended in the sawdust compost providing a slow release quality that promotes lush and hearty growth in vegetable gardens, lawns, flowers and shrubs. Because of SUP'R Green's slow release quality, one application yearly is all that is needed. SUP'R Green is available at many farm and feed stores.
