The study looked at different forms of potassium in maize-growing soils in Haveri district, Karnataka, India. They found that the available potassium in the red soils varied from medium to high levels, influenced by farming practices and inputs like fertilizers and manure. Water-soluble potassium levels were higher in areas where potash fertilizers were used. Exchangeable potassium was high due to fertilization and organic matter. Non-exchangeable potassium increased from leaching and adsorption. Lattice potassium levels varied, and total potassium content in the soils ranged from 0.97 to 1.35 percent.
