As a result, the nitrogen and phosphorus should be more plant available, but also may be more susceptible to loss to the environment.<\/p>\n<h2>Agronomic Approach<\/h2>\n<p>Two forms of manure were compared to urea as sources of nitrogen for grass growth. Raw dairy manure and anaerobically digested dairy manure (co-digested with pre-consumer food waste) were applied at equal amounts of total nitrogen.
