Explanation

Important soil properties: texture (sand/silt/clay ratio), structure (how particles clump), porosity (pore spaces), water-holding capacity, pH (acidity/alkalinity), and nutrient content.

These properties affect: root penetration, water availability, aeration, nutrient supply, and workability. Different crops need different soil conditions.

Farmers can modify some properties: adding organic matter improves structure, liming corrects acidity, irrigation addresses water issues. Texture cannot be changed economically.
