Utilization of decomposed water peanuts us basal manure for wheat and rice

Comparative experiments for utilizing decomposed water peanuts as basal manure was conducted on fluvo quic soil. It was found that the water peanut did not have weed problem when they were decomposed with 2 to 4% ammonium carbonate until stems fell off. The decomposed water peanuts could be used as basal manure for rice and wheat, and the humification rate was 0.18. The K efficiency of the water peanuts manure was higher than chemical K fertilizers. Consecutive use of the manure increased the yields of rice and wheat by 4 to 5%.
