Abstract:
Nitrogen releasing of fertilizers was studied1The results showed that nitrogen releasing of stable organic-inorganic compound fert ilizer（LF3-3) was slower at early stage af ter the fertilizer applied to soil, this would be beneficial to crop growth in seedling stage1Ammonia volatilization amount from ground surface was apparently low er than the other similar compound fert ilizers; as compared with urea, ammonia volatilizat ion-inhibit ion rate was 57%.When LF3-3 was applieclone time, the wheat y ield was the highest, nitrogen ut ilizat ion rate of the fertilizer was 40.8%, and it was 5.3% hig her than the other similar compound fertilizers.
Key words:
Nitrogen releasing,
Nitrogen utilization rate,
Ammonia volatilizat ion-inhibition rate
