Why is soil porosity influence to plant growth and development?

Answer 1

A sandy soil is quick draining, but may be poor in nutrients. A clay soil is poor draining, and may be waterlogged for long periods. Though clay soils may be richer than sandy soils in nutrients, having waterlogged roots may rot off a plant's roots. A well draining, nutrient rich, loamy soil will hold water, yet drain enough to avoid root rot, so allowing the plants to thrive.

Answer 2

Soil porosity influences plant growth and development by affecting the movement of water, air, and nutrients in the soil. A well-structured, porous soil allows for good root aeration, water infiltration, and nutrient availability, which are essential for plant growth. In contrast, compacted or poorly structured soils with low porosity can restrict root growth, oxygen availability, and nutrient uptake, leading to stunted growth and poor development of plants.
