Effect of Tillage on Soil Nitrogen; A Review

Bariot Hafif

Abstract

Most farmers think that soil tillage activity is still one important part of efforts to increase crop production. But some of them have understood that reduced or no tillage (NT), in addition to saving money and time, not reducing crop yields even can also conserve and improve soil productivity. Several experiments have proven the advantages of NT compared with conventional tillage (CT). Without tillage practices in the long run have a good contribution to the total nitrogen content in the top soil. N mineralization levels were also higher in NT than under conventional tillage. Meanwhile to reduce emissions of N which indicated higher under NT than in CT is to avoid the practice of monoculture cropping systems, and the inclusion of legumes into cropping systems.
