Forms and Distribution of Potassium and Their Relationships to Different Characteristics of the Soil in the Soils of Pipari Village, District Khargone of Western Madhya Pradesh, India

Abstract

Forms and distribution of potassium were examined in 150 soil samples taken from Pipari village, Khalgone (MP) district. Surface (0-15 cm) soil samples were collected from 150 parcels of land in Pipari village. The concentration range of water soluble potassium, exchangeable potassium, available potassium, non-exchangeable potassium, lattice potassium and total potassium in soil is 3.82-35.8, 95.1-371.92, 108.35-379.20, 164.0-388.8, 8599.8-15865.32, 9066.2-16249.12 mg kg -1. For all potassium forms, EC showed negative correlation. The pH showed highly negative correlation with water soluble potassium (r= -0.111**), exchangeable potassium (r= -0.45**), available potassium (r= -0.060**) and positive correlation with lattice potassium (r= 0.034*) and total potassium (r= 0.033*). Organic carbon was positively correlated with all potassium forms except water-soluble and non-exchangeable potassium (r = -0.034 *). CaCO3 has a positive correlation with water soluble potassium (r = 0.046**), lattice potassium (r = 0.090**) and total potassium (r = 0.084**) and total potassium (r= 0.084**) and highly negative correlation with exchangeable potassium (r= -0.147**), available potassium (r= -0.130**) and non-exchangeable potassium (r= -0.060**). Available nitrogen showed highly positive correlation with lattice potassium (r= 0.063**) and total potassium (r=0.062**). Available phosphorus showed negative correlation with exchangeable potassium (r= -0.046**) and available potassium (r= -0.046**) and positive correlation with lattice potassium (r= 0.090**) and total potassium (r= 0.087**). Highly positive correlation noticed between different forms of potassium except lattice potassium (r= - 0.113**) and total potassium (r= - 0.095**).
