Plants absorb many of these pesticides, and when they decompose, they cause soil pollution since they become a part of the land. 2 Scheffer & Schachtschabel (2010). IV. A deficiency of oxygen has been found to check the nutrient and water absorption by plants. Methane emissions originate from wet, oxygen-poor soils in peat lands or swamps, and from rice fields. For most land plants, the supply of oxygen in the soil air must be kept above 10%. Soil porosity is the term used to describe the amount of open space or pore space that can be found between particles of soil. Other chemicals damage the composition of the soil and make it more erodible by water and air. Similarly, promoting soil fungi helps plants extract nutrients from the soil while increasing resistance to disease and building healthy soil structure. Air is a third critical resource for humans, plants, animals and all other organisms within a natural area. When the soil air gets heated during the day, it expand and move out of the soil porespace into the atmosphere. Some bacteria thrive in low oxygen environments, But the chemical processes they use are different and generally slower and less complete.

Soil organisms are important for sustainable food systems and mitigating climate change. Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil. Fertile soils are the foundation for agriculture because it provides a hospitable place for plants to live and grow by providing dissolved minerals, and moderating temperature fluctuations optimal for plant growth. Soil air differs from atmospheric air by having a higher carbon dioxide and lower oxygen content. The role of soil air in relation to fertility of soil and plant growth are given below: Soil aeration is an important factor in the normal growth of plants. Breaks up compacted soil. Here are five reasons to treasure our often overlooked natural resource. To avoid con fusion let us use the following figures as representing the average composition of the soil air; the percentages are by volume: N2=79.2, O2=20.6 and CO2=0.25; for at Soil is composed of both bioticliving and once-living things, like plants and insectsand abiotic materialsnonliving factors, like minerals, water, and air. As soil quality decreases, so does the nutritional value of the crops that are produced. The presence of oxygen in the soil promotes easy germination of seed this is because oxygen constitutes 23% of the atmospheric air. Thus, a well-aerated soil is one in which gases are available to growing aerobic organism (including higher plants) in sufficient quantities and in the proper proportion to encourage optimum rates of the essential metabolic processes of these organisms. Soil is teeming with life, but life in soil has somewhat remained the deep ocean of the land: Little is known about the myriad organisms below ground that interact with soil and the wider environment.
