Low soil porosity
WebThe low-value porosity zone refers to the zone where porosity is lower than the lower limit of the effective reservoir on the depth-porosity plot (Fig. 5.7 B, Zone A). The high … WebIf a soil is compacted, the soil solids are packed into a smaller volume, and the particles get packed closer together. This results in less total pore volume. Thus as soil density increases, soil porosity decreases. Soil density is relatively simple and cheap to measure.
