The physical-chemical properties of soil play a crucial role in determining its fertility. The pH level indicates soil acidity or alkalinity, typically ranging from 4.0 to 8.5. The amount of organic matter affects soil fertility, usually ranging from 1% to 5%. Cation exchange capacity (CEC) reflects the soil's ability to retain nutrients, usually measured in sm/kg. Soil color is usually determined by organic matter and minerals
