Conservation agriculture (CA) draws an attention towards maintaining sustainability with productivity enhancement and by applying principal of zero/minimum tillage. It plays a key role on the availability of potassium (K) contents in soil. It was observed that the release pattern of different forms of potassium is regulated by different tillage practices and cropping system. Keeping in these views, the present study has been designed targeting long-term CA experiment on "Resource conservation technologies for stabilizing yield under different cropping system" which was started in the year...
