Soil microbiology: It provides support for the survival of many bacteria, algae, fungi, etc..These bacteria and microbes present in soil help in environmental balance like retaining of moisture, the decay of dead bodies of animals, plants, etc., scavenging of waste and other toxic chemicals including plastic.

Plants have evolved to have a symbiotic relationship with certain soil organisms in which the plants … There are following functions of water and important for plant growth and crop production. Chemical fertilizers can lead to salt buildup in the soil, and in the long term, they can alter the pH level of the soil, increase pests, and alter microbial ecosystems. Humus is an important nutrient source for plants, and it is important in aggregating soil particles. All parts of soil are essential to plant development, and each is necessary for plants to survive. This includes compost, manure, bone, blood, and feather meal, and kelp. - principle source for soil, needed for plants to grow, animals eat plants, building block of RNA, DNA, & proteins - found in poor alkaline soils (basic), convert nitrogen found in the soil … Much of water remains in the soil as a thin film.

Another important aspect of soil porosity concerns the oxygen found within these pore spaces. Water serves as the solvent and carrier of food nutrients for the growth of plants. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants … O) Organic matter: Litter layer of plant residues in relatively undecomposed form. A primary reason is that soil pores contain the groundwater that many of us drink. Water itself acts as a … 2. Not all the water, held in soil, is available to plants. The composition of the components inside soil varies to create different soil types. All plants need oxygen for respiration, so a well-aerated soil is important for growing crops. OM is always in the process of decomposing, until it becomes humus. Functions. Why do plants exude carbohydrates out of their roots to feed soil organisms? Most soil organisms function best at the same temperatures people are comfortable at, or more specifically, in the 70s or low 80s F. 7.
