WebSoil formation takes place by the process of weathering when the rocks break down to form soil particles. This rock degradation takes millions of years to complete. Physical, chemical, and biological weathering are the responsible factors for the creation of soil. The influences of heat, cold, water, wind, and rain cause the bedrock to crumble. WebKey processes and reasons for changes in soil pH in agricultural systems are described below. Fertilizer use Use of mineral or organic fertilizers in agriculture increases inputs of nutrients to soils, and the form in which the nutrients are applied and their fate in the soil-plant system determine the overall effects on soil pH.
