Abstract: The average manure recycling ratio in China is lower than 40 %, implying that over half of the nutrients in manure is lost to the environment. To reduce environmental pollution caused by nitrogen (N) and phosphorus (P) losses, it is crucial to enhance manure recycling and reduce N and P fertilizer inputs. Manure provides nutrients and reduces soil acidification due to high levels of potassium (K), calcium (Ca) and magnesium (Mg).
