Twenty soil samples with the background of different management practices, soil type and depth were collected representing different villages in Nalgonda district of Telangana state, India, in the year 2016. The purpose was to assess the potassium supplying capacity of these variable soils through Neubauer technique with maize as test crop. Standard methods were adopted to assess different potassium forms in the samples. In this study the Neubauer value of 297 mg 100g-1 soil, was recorded in the soil of Kondamadugu (Bibinagar mandal) indicating the highest amount of potassium uptake while, the lowest uptake of 59 mg 100g-1 soil was recorded in the soils belonging to Kacharam village. Neubauer values showed positive correlation with all the fractions of potassium. However, maximum positive correlation is shown with available and exchangeable K (r = 0.21), indicating that the available and exchangeable potassium had pronounced effect on the uptake of potassium by the crop plants over other fractions.

Key words:   K supplying capacity, Neubauer technique, K fractions, Correlation
