Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1] Lack of oxygen in the soil can impact plant growth.
Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals.
Lime can improve crop yield and the root system of plants and grass where soils are acidic. It does this by making the soil more basic, allowing the plants to absorb more nutrients. Lime is not a fertilizer but can be used in combination with fertilizers. [3] [4] Soils become acidic in several ways.
Plants and animals utilize soil for food and shelter, disturbing the upper soil layers and transporting chemically weathered rock called saprolite from the lower soil depths to the surface. [3] Terrestrial bioturbation is important in soil production, burial, organic matter content, and downslope transport.
Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...
Soil is composed of organic matter (decomposing plants, animals, and microbes), biomass (living plants, animals, and microbes), water, air, minerals (sand, silt, and clay), and nutrients (nitrogen, carbon, phosphorus). [4] For optimal plant growth, a proper carbon to nitrogen ratio of 20–30:1 must be maintained. [3]
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. [11] Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.
