Cite article:- G.Arunachalam* Saraswathyand R. (2024). CHANGES IN PHYSICO-CHEMICAL PROPERTIES AND NITROGEN TRANSFORMATION IN THE ROOT-ZONE SOIL OF DIFFERENT RICE CULTIVARS IN PROBLEM SOILS. Indian Journal of Agricultural Research. 36(4): 282 - 285. doi: .
A pot culture experiment was conducted to study physico-chemical and chemical properties of soils as influenced by root system of two rice varieties in acid and alkali soils and also nutrient uptake by rice varieties. It was observed that the submergence increased the pH considerably in acid soils and marginally in alkali soils while EC increased in both the soils. But in root-zone soil, the pH increased in acid soil and decreased in alkali soil. Root-zone soils recorded high NH 4-N, low organie-N, available-N and total-No The increase in NH 4-N content was more pronounced in alkali soil than in acid soil. But the uptake of rice varieties under acid soil was more than the varieties under alkali soil.
