This is the first I've heard of the studies done on N20 emissions caused by cover crop and manure usage. Thank you Dr. Bhowmik for opening this topic. Mentioned was the practice of spreading when it is under 50 deg F, Are there any other conditions under which the N20 Is high? And conversely a low or no emission experienced? Possibly is there a link to a full article on this topic? Would be excellent to know as I do know farmers who spread manure in early spring before chance of frost is past. Thank you!
