dc.description.abstract	A laboratory evaluation and an uptake study using Neubauer seedling technique was carried out for evolving a single common extractant suitable for extracting available P and available Kso as to simplify the process of extracting these available plant nutrients in soil testing work. The study was conducted in three phases, viz., an initial study, preliminary screening and a final selection using different extractants. The triacid (0.06 N H2S04 + 0.05 N HCI + 0.05 A/ oxalic acid) with a soil solution ratio of 1 :1 0 and equilibration period of 30 min was found to give very good correlation with Bray No. 1 P and NH4OAc (std) K and this extractant can be recommended for different soils of the state.	en_US
