Soil is an essential natural resource that needs to be used properly and protected. Soil compaction, which increases the density of the soil, is done as part of the building process. The soil ⦠It is vital for our survival on the earth. It is the medium of plant growth and supports different types of living organisms on the earth. As a core component of land resources, agricultural development and ecological sustainability, it is the basis for food, feed, fuel and fibre production and for many critical ecosystem services. Discuss human dependence on the soil. If not done, structural failure can result.
