Why is soil so important?
The soil is essential for our well-being. It is responsible for 95% of the global food production, is home to 25% of all terrestrial species and plays a vital role in storing water and carbon, helping to mitigate climate change and reduce flooding. But soils are degrading around the globe.
Structure is directly related to the ability of soils to provide benefits. There is a growing awareness that good soil structure should be promoted in agricultural and environmental policy.
The uppermost layer on the Earth is the soil. Mineral soil is a mixture that includes organic matter, minerals and gases. As the weathering of bedrock and decaying organic material combine, soil gradually develops over time. The soil is usually formed in layers, also known as horizons. These layers are different in texture and colour.
Why is soil so important?
The soil performs a wide range of functions, without which life on earth would be impossible. By anchoring roots, it provides a growing environment for plants. It cleans and filters our water, and helps to prevent natural hazards like flooding. It is a biodiverse area. It is also the largest carbon store on earth, which helps regulate climate.

What does a good soil composition mean?
The soil structure is the arrangement of solids within soil. Aggregates are formed when organic compounds and mineral ions combine to form solids. Pore spaces are the gaps between these aggregates. A ‘well-structured’ soil for agricultural use will have a network of pore space to allow air flow, drainage and root growth. A ‘good’ soil for agriculture is typically thought to contain around 50% solids and 25% air, but the percentages will vary depending on soil type.
