Soil Types - JSON

Soil types are primarily classified by particle size and composition. Sandy soil has excellent drainage and aeration but low water and nutrient retention. Clay soil has excellent water and nutrient retention but poor drainage and aeration. Humus soil is rich in organic matter and fertile but has low strength and high compressibility. Understanding these soil characteristics and implementing appropriate soil improvement can create an environment suitable for crop growth.
