Soil structure has an important influence on plant growth as it affect moisture relationships, aeration, heat transfer, and mechanical impedance of root growth. Good seedbed preparation is related to moisture and heat transfer which are important in seed germination. A good porous structure is needed for water infiltration and air exchanges between atmosphere and the soil, and microorganism activity for nutrient generation.
Water carries nutrients to the plant roots by capillary action.
It is necessary to maintain conditions for proper aeration for microbial and other plant and animal life in soil.
