Fig. 4. Effects of lowered protein content (comparison of Manures B and A), adding acidifying salt (Manures B and D), increasing total nonstarch carbohydrate contents (Manures I and B), and fermentable nonstarch carbohydrate content (Manures E and G) on potential NH3 and CH4 emission during anaerobic storage, denitrification potential (DNP) after soil application, potential N2O emission after application to a sandy and clayey soil, the content of mineral N in the manure, and the content of stable organic matter (OM) in the manure (i.e., the residual organic matter after incubation of manure in soil at 20°C during 44 d).
