Management of iron toxic soils with FYM and K for growing rice under submergence


, : Management of iron toxic soils with FYM and K for growing rice under submergence. 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: 237-246

In a pot culture experiment conducted to evaluate the effects of farmyard manure (FYM) and K on rice grown in Fe toxic soils under submergence revealed that symptoms of Fe toxicity appeared in rice plants grown in soils treated with as low as 300 mg Fe/kg but no FYM and/or K. In FYM treated soils proportionate increase of soluble non-toxic org-Fe along with increase in inorganic Fe might have reduced its toxicity.
