WebJun 24, 2024 · This empty space in soil enables root growth, water retention, atmospheric gas exchange, and water drainage. A soil ideal for plant growth will have approximately 50% of its total volume as pore space. Sands contain less pore space than any of the other textures and clay usually has the most. WebSoil porosity is also dependent on, and inversely related to, soil density. If a soil is compacted, the soil solids are packed into a smaller volume, and the particles get packed closer together. ... One method for determining bulk density is the “core” method. A (relatively) undisturbed, cylindrical soil core is collected using a device ...
