The study looked at different forms of potassium in soils in Kashmir's Ganderbal district. They found that rice fields had more water-soluble, exchangeable, and available potassium, while apple and maize fields had more fixed, non-exchangeable, and total potassium. Organic carbon and clay content were positively related to potassium levels, while calcium carbonate and sand content were negatively related. Soils under maize had higher organic carbon, while apple soils had more calcium carbonate. Overall, the order of potassium forms was total > lattice > fixed > non-exchangeable > available > exchangeable > water-soluble.
