The study looked at different types of phosphates in agricultural soils in Northern Greece and how they are affected by soil type and farming practices. Acidic phosphates were more active in Entisol and Vertisol soils, while alkaline phosphates were more prevalent in Alfisol. Soil pH and farming practices influenced phosphate activity. Acidic phosphates were linked to plant growth, phosphate absorption, and activation in the soil. Alkaline phosphates were related to microorganism growth, phosphate absorption, and activation in the soil. Acidic phosphates were higher in cultivated soils, while alkaline phosphates were higher in uncultivated soils. Adsorbed phosphates in soil colloids were lower than free phosphates and depended on the activity of acidic and alkaline phosphates.
