Soil structure & why it's important Rolawn. Massive—There is no apparent structure. Soil particles cling together in large uniform masses. Platy—The units are flat and plate-like. They are generally oriented horizontally. Plates overlap, usually causing slow permeability. E-unit: Understanding Soil Texture and Structure Page 5 AgEdLibrary.com, Soil texture and structure determine physical (air porosity, available water, hydraulic conductivity, relative gas diffusivity), chemical (ion exchange capacity, redox conditions, pH), and biological (activity of microorganisms) properties of the soil which then affect the water and mineral uptake by the plant. Consequently, the main effects of.

Soil Texture and Structure SpringerLink. Soil structure describes the arrangement of the solid parts of the soil and of the pore space located between them. It is determined by how individual soil granules clump, bind together, and aggregate, resulting in the arrangement of soil pores between them. Soil structure has a major influence on water and air movement, biological activity, root growth and seedling emergence., the texture is determined from the Soil Texture Triangle. While soil texture is generally considered a fixed property that cannot be changed, soil structure can be modified, for better or worse, in a relatively short period of time.
