I think that the

• Soil type variations affect nutrient availability and water retention.
• Different zones support different crops based on soil characteristics.
• Soil fertility varies with organic matter and mineral content.
• Climate-soil interaction influences overall crop productivity.
• Understanding soil diversity helps in better land use and crop planning.

Sand ,Silt and Clay play a important role in the determination of physical properties of soil and cultivation.Our soil is old and fragile, it can be damaged by farming techniques,poisoned by rising salts and lost by water and wind erosion.

Biotic factors i-e microbes, pest and natural enemies and abiotic temperature, humidity, soil types including soil structure and texture and rainfall can influence crop productivity.
