How does potassium move in the soil
The hydrosphere is the largest reservoir for potassium, holding an estimated 552.7 x 10 tonnes (552.7x10 Tg). Leaching and erosion carry 1.4 x 10 tonnes (1400 Tg) yr of potassium in soil solution into groundwater, rivers, and oceans. Some potassium in the atmosphere also enters the hydrosphere through precipitation. Potassium in sediment pore fluids is removed from solution by the authigenic formation of clay, which is then subducted, along with potassium deposits and oc… WebThe total amount of potassium in soil ranges from 5 to 25 tons per acre. While this seems like a lot of potassium, only a small amount is plant-available at a particular point in time. Most potassium is in the structural component of the soil. Sandy-textured soils have much less potassium than fine-textured, clay soils.
