Neubauer seedling experiment was carried out for determining the potassium supplying capacity of different representative soil series of order Entisols, Inceptisols and Vertisols collected from agriculture college Kolhapur and different research stations of Sub-montane zone of Maharashtra. In this experiment, 50 seedlings of wheat were made to feed exhaustively on 100 grams of soil mixed with 100 grams of quartz sand for 17 days in plastic dishes. The total K uptake by wheat seedlings from different soil series was calculated from which the control value was deducted to obtain the “root-soluble” K in soil. These values are designated as the Neubauer numbers, expressed as mg per 100 g of air-dry soil. The Neubauer limit value for wheat is 20 mg K per 100 g of dry soil and the soils which are having less value than the above is being considered to have poor potassium supplying capacity. Among the different soil series, the highest potassium supplying capacity was observed in Koregaon series (Vertisol) of A.R.S., Karad with neubauer number 38 and the lowest potassium supplying capacity was noticed in Sathesai series (Entisol) of N.A.R.P., Shendapark with neubauer number 7.90. The highest potassium supplying capacity was noticed in Vertisols followed by Inceptisols and Entisols.
