Abstract:

Potassium (K) is vital to many plant processes and the knowledge about different forms and availability of potassium is must while studying the response of crops to K. Because Potassium supply to crop plants is a complex phenomenon involving relationships among various K fractions in soil. Potassium is available in the soil in different forms and amount viz., water soluble K, exchangeable K, fixed K and mineral K. Plants utilize not only the readily available K but also the non-exchangeable and mineral K during the crop growth. The potassium availability to plants is determined by the rate of change in the dynamic equilibrium between different forms of K in the soil which in turn is controlled by the mineral make up, rate of weathering and exchange properties of the soil. The distribution of different forms of K in soils is related to a number of soil properties such as soil minerals, particle size distribution, organic matter and pH. The relationship between K forms and soil properties can be used to predict K availability in soil.
