Soil is the upper layer of Earth’s lithosphere, located between the stone foundation and the surface. Soil is comprised of particles of minerals, organic matter, water, air and living organisms. Soil is a non-renewable asset and must be used in a sustainable manner with its functions preserved. Adverse impacts on the soil must be avoided to the greatest possible extent. Soil is, besides air, water, sea, landscape, flora and fauna and Earth’s lithosphere, a constituent part of the environment. Soil protection includes the preservation of the health and functions of the soil, prevention of soil damage, monitoring the status of the soil and changes in its quality as well as remediation and restoration of damaged soil and sites. Pollution or damage to soil is considered to be an adverse impact on the environment, while determining acceptable limit values of soil quality is carried out on the basis of special regulations.
