Soil biota plays an integral role in soil ecosystems by decomposing leaves, downed logs, and animals, and also providing the primary nutrient source for vegetation. Factor of Time. This refers to the breakdown and decomposition of rocks and minerals by factors including air, water, sun and frost. Key words: Ecology, diversity, Hygrocybe spp., Biodiversity Action Plan. The soil biota (and hence soils as a whole) are responsive to human-induced disturbance like agricultural practices, deforestation, pollution and global environmental change, with many negative consequences including loss of primary productivity, loss of cleansing potential for wastes and pollutants, disruption of global elemental cycles, and feedbacks on greenhouse gas fluxes and erosion. Various soil biota facilitate soil formation (e.g., 25 fungi, bacteria, termites, earthworms) Soil formation Various saprophytic and litter feeding invertebrates 760 (detritivores), fungi, bacteria, actinomycetes and other microorganisms Waste recycling Global economic benefits (USD x 109 yr-1) Ecosystem service Soil organisms involved root.

Encountering soil biota is an engaging and exciting activity for undergraduate students, most of whom have little or no experience with this topic. Soil erosion is removal of soil due to movement of water and/or air. Biofertilizers are more cost-effective as compared to chemical fertilizers. Pedologists (scientists who study the origin and composition of soils as a component of natural systems) continue to learn more about soil morphology, chemistry, mineralogy, and biota, thus tighter limits on groupings of soils are being defined. This helps you give your presentation on Soil Biology in a conference, a school lecture, a business proposal, in a webinar and business and professional representations.

Impact of Soil Pollutants on Soil Biota/Microbes: Soil pollutants like metals, pesticides, organic sub­stances showed detrimental impacts on soil fauna, flora and other microbes. The catena concept nature of soil varies with position on a slope. The soil is the part of the earth’s surface, which includes disintegrated rock, humus, inorganic and organic materials. Soil biota can be grouped according to size in micro-, meso- and macrobiota. The soil contains a vast array of life forms ranging from submicroscopic (the viruses), to earthworms, to large burrowing animals such as gophers and ground squirrels.

Key soil character parameters used to evaluate general activity of the biopile included total Kjeldahl nitrogen (TKN, a measure of both ammonia and organic nitrogen), ammonia nitrogen (NH3-N), nitrate plus nitrite nitrogen (NOx-N) compounds, and total organic carbon. Soil Porosity and Permeability • Porosity is the total amount of pore space in the soil (30 to 60%) – Affects the storage of air and water – Affects the rate of movement of air and water • Permeability is the ease in which water, air, and plant roots move through the soil – Ease of air, water and root movement – Affects rate of water intake and drainage • Porosity and permeability are affected by soil texture, … Brown Earth Gley Podzolization This is an intense form of leaching.
