Abstract:r availability in soils and Cr uptake and accumulation by rice were studied. Theamounts of Cr extracted with various extractants followed the order :.1mol/L HCl>0.05mol/L EDTA>0.005mol/LDTPA, 1mol/L NH_4 Ac, Under the condition of simulatedpot culture, Cr content in rice grain was positively correlated to be the amount of Cr extract-ed with 0.05mol/LEDTA, but was not correlated to the amounts of Cr extracted with otherthree extractants.0.05mol/LEDTA was proposed to the best extractant for available Cr, The...
