These soil components fall into two categories. While there are some plants that can live in water or air, most plants . stems etc.) A look at how our Soils help to combat climate change in their role of sequestering CO2, and how our collective habits can damage this benefit with potentially devastating consequences. Soils are home to earthworms, termites and a myriad of micro-organisms that fix nitrogen and decompose organic matter. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. Soil filters the water we drink, grows the food we eat, and captures the carbon dioxide that causes climate change. 1. Text on this page is printable and can be used according to our Terms of Service. We build on soil as well as with it. Healthy soils produce healthy crops that in turn nourish people and animals. On the root crops such as carrots and sugar-beets and influence is most noticeable. Responsible companies, including Unilever, are making serious commitments to minimize the damage done to the soil, while actively working to regenerate degraded land. Since soil is made of particles Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Within recent times, however, the breathing of soil has accelerated: land-use change and agricultural intensification have added pressure on soils and have caused greenhouse gas emissions from soil to increase3.

Gases diffuse from the atmosphere into the soil and back out again, like breathing. Aeration promotes root growth and absorption of water and nutrients by plants. Under poor aeration condition (this condition may arise when water-logged), plants exhibit water and nutrient deficiency. Soil is the largest carbon sink after the ocean and holds more carbon than all terrestrial plant life on the planet. Abnormally shaped roots of these plants are common on compact, poorly aerated soils. Sustainability: Recycling helps to create a sustainable society by reducing the need to rely on non-renewable resources. The supply of oxygen to roots in adequate quantities and the removal of CO2 hampers the growth of plant roots. Composed of minerals, water, air and organic matter, soil provides primary nutrient cycling for plant and animal life and acts as a basis for feed, fuel, fibre and medical products as well as for many critical .
