Management of low-K soil through integrated nutrient supply system

, : Management of low-K soil through integrated nutrient supply system. Proceedings of the Seminar on Problems and Prospects of Agricultural Research and Development in North East India, Assam Agricultural University, Jorhat, India, 27-28 November 1995: 227-232

A long term experiment conducted to study the effect of integrated nutrient supply in a rice-rice sequence in an Inceptisol with low potassium status showed that continuous application of graded levels of NPK for 7 years significantly increased all forms of K in soil. Integrated treatments replacing 25 and 50% chemical N through organic sources registered significantly higher values of all forms of K over chemical fertilizer treatments.
