Soils & Soil Physical Properties Unit 2.1 | Part 2 – 5 Introduction Introduction: Soils & Soil Physical Properties UNIT OVERVIEW This unit introduces students to the components of soil and soil physical properties, and how each affects soil use and management in farms and gardens. Physical Properties of Soils: Physical properties of the soil can be discussed under the following heads: (1) Soil separates and texture, (2) Structure of soil, (3) Weight and soil density, (4) Porosity of soil, (5) Permeability of soil, (6) Soil colour, (7) Temperature of soil, and (8) Soil Plasticity, Compressibility and Erodibility. Soil consists of rock and sediment that has been modified by physical and chemical interaction with organic material and rainwater, over time, to produce a substrate that can support the growth of plants.” Soils are an important natural resource.
