Abstract:
Nitrification in the presence of 0 to 3000 pg of each of Al, Fe and Mn as chlorides in peat (g ) has been studied. About up to 40 days the added elements could not produce any appreciable change in the processes of N mineralization and transformation. However, thereafter the salts suppressed nitrification and encouraged ammonification. The interalia transformation of N increased with concentration having the threshold value of 2000 \xg peat. The divergence of two trend (ammonification and nitrification) in the presence of metals attained the maximum at about 80 days. Addition of elements in freshly prepared peat was found to be more responsive than the aged one.
