Liming Acid Soils Boosts Phosphate Absorption, Revolutionizing Crop Growth.
Liming acid soils changes their pH levels, affecting how they absorb phosphorus. Three different soils were studied, with one rich in kaolinite clay and the others in illite. The amount of phosphorus absorbed varied depending on the soil's clay content and other factors. Uchagaon soil absorbed the most phosphorus due to its high kaolinite content. Phosphorus absorption increased slowly with lime until a certain point, then sharply increased. All soils absorbed the most phosphorus in a solution with calcium chloride, followed by potassium chloride and water. Aluminum ions released from clay layers and forming polymers at higher pH levels played a key role in phosphorus absorption in limed soils.
