What factors affect soil fertility?
Soil fertility refers to the soil’s ability to provide essential nutrients to plants for healthy growth. It is influenced by several physical, chemical, and biological factors.
The presence of essential nutrients like nitrogen, phosphorus, and potassium directly affects soil fertility.
Well-structured soil allows proper air circulation, water movement, and root penetration.
Decomposed plant and animal material (humus) improves nutrient availability and soil texture.
The acidity or alkalinity of soil affects how easily plants can absorb nutrients. Most crops grow best in neutral pH.
Beneficial microbes help decompose organic matter and make nutrients available to plants.
Proper moisture levels are necessary for nutrient absorption and plant growth.
Temperature and rainfall influence soil formation, nutrient cycling, and overall fertility.
Soil fertility is not determined by a single factor but by the combined effect of nutrients, structure, biological activity, and environmental conditions.
