Three types of chicken,swine and cattle manure from were composted under aerobic conditions.Physicochemical properties of composted products were determined,and the effects of these products on two leaf vegetable production were further evaluated via field trials.Study results showed that: the majority of N in these products were in the form of organic N,which accounted for 50% of total N,and the majority of K in these products were in the form of inorganic K,which accounted for more than 90% of total K.the concentrations of heavy metals such as Pb,Cd,Cr,As,and Hg in these products were lower than the threshold standard concentrations of these heavy metals for the commercial biologically organic fertilizers in our country.applications of these composted products resulted in lower leaf vegetable yields(Chinese flowering cabbage and Ca-bbage) compared to equivalent N applications from chemical inorganic fertilizers,but no yield differences were observed among applications of the three composted products.Basal applications of these composted products at sufficient N rates improved quality of leaf vegetables with higher concentrations of ascorbic acid(Vc) contents,and lower nitrate(NO3-) concentrations.
