Effect of chicken manure surveyed

These studies suggest that both spreading in the late winter or in connection with spring farming operations is early enough for the nitrogen to be available for spring crops. Research also shows that one cannot base fertilizer recommendations on the ammonia content as one does with many other manure types. The nitrogen effect must be calculated on the total content of nitrogen.

The research project "Nitrogen mineralization patterns and impact on the crop after fertilization with poultry manure" is funded by the Swedish Farmers’ Foundation for Agricultural Research.
