Loamy soil is considered the ideal soil texture for plant growth because it contains a well-balanced mixture of sand (approx. 40%), silt (approx. 40%), and clay (approx. 20%).
It combines the good aeration and drainage properties of sand with the high nutrient retention, cation exchange capacity, and moisture-holding capacity of clay and silt.
Pure sandy soils suffer from rapid leaching and low water retention, while heavy clay soils suffer from poor aeration, high bulk density, and waterlogging.
