Abstract
A pot experiment was conducted where a sandy clay loam saline-sodic soil (pHs 8.6, EC. 21 dS mol, SAR 183.7 and OR 5.6 me 100 g-I) was treated with phosphogypsum @ 50 and 100% OR and FYM @ 10 and 20 tons acrel, A synthetic irrigation water (EC 2 dS mol, SAR 12, RSC 3 me VI) was applied to wheat andrice crops. The soil improvement was more with phosphogypsum followed by FYM. There was some adverse effects of high Mg in irrigation water but because of soil salinityjsodicity, overall tendency remained towards improvement.
