"Soil biology" is the study of microbial and faunal activity and ecology in soil. "Soil life", "soil biota", "soil fauna", or "edaphon" is a collective term that encompasses all the organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. These organisms include earthworms, nematodes, protozoa, fungi, bacteria and different arthropods. Soil biology plays a vital role in determining many soil characteristics. The decomposition of organic matter by soil organisms has an immense influence on soil fertility, plant growth, soil structure, and carbon storage. As a relatively new science, much remains unknown about soil biology and their effects on soil ecosystems. The soil is home to a large proportion of the world's biodiversity. The links between soil organisms and soil functions are observed to be incredibly complex. The interconnectedness and complexity of this soil ‘food web’ means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil. We know that soil organisms break down organic matter, making nutrients available for uptake by plants and other organisms. The nutrients stored in the bodies of soil organisms prevent nutrient loss by leaching. Microbial exudates act to maintain soil structure, and earthworms are important in bioturbation. However, we find that we don't understand critical aspects about how these populations function and interact. The discovery of glomalin in 1995 indicates that we lack the knowledge to correctly answer some of the most basic questions about the biogeochemical cycle in soils. We have much work ahead to gain a better understanding of how soil biological components affect us and the biosphere Wiz Science™ is "the" learning channel for children and all ages.

Todays episode we are going to continue the exploration of our garden soil series. If you have missed any episodes in this series click here to view the playlist. In order to get a complete understanding of the relationship between our garden soil and plants we need to step back in time. It is important to understand what is forming earths soils. Horizon shot with little or no detail of the land itself Lets step back 400 million years in Earths History. Soil formation or paedogenesis is driven by physical, chemical, biological and anthropogenic or in other words human cause interactions with organic and inorganic mediums. Soil formation began some 400 million years ago in the Devonian period. Before that time there was very little oxygen in the atmosphere and no organic material on land. Around that time oxygen began to appear in significant quantities as a result of the development of Photosynthetic processes in organisms. Around the same time there is evidence to suggest land was being colonized by its first organisms. Fast forward 400 million years and we have an amazingly complex terrestrial ecosystems including our gardens. As far back as there are human records people have been studying soil science. This is because for the most part our civilizations depend heavily on food from farming or foraging. For the last 400 million years soils have been formed largely by the Parent Material, Climate -- Temperature and water changes, Topography, and Time The Parent Material is the unconsolidated material that forms the base for soils. Typically weathered from solid types of rock by either physical or chemical processes. This material is either the material that the soil sits on or has been transported in by wind, water glaciers or gravity. Interestingly because of the diversity of parent materials that are transported in they are commonly more fertile then there in place counterparts. Climate is usually the biggest factor in soil formation. Changes in temperature and water regimes drive both physical and chemical weathering of parent materials and soils. Temperature influences soils by the change caused by daily and seasonal fluctuations. Large shifts in temperature change the soils water regime either stimulating biological activity or inhibiting it. Water is involved in most reactions in soil and as it moves through, interacts with and leaves the soil it has lasting effects. Most notably leaching minerals water in solution away from the soil. Topography is the shape of the land itself and plays a key role. It influences not only the location of soil formation but the radiant energy and water regimes that shape and change the soil. Organisms or the biota play an important role in soil formation and are made up of vegetation, animals, bacteria and fungi. Plants for instance make up most of the organic material found in the soil and can influence the weathering process. Finally we get to time which ultimately allows all of the earlier mentioned factors time to work. All of these factors combine to form the basics that plant life needs to grow. The soils holds organic material, water and gasses allowing the plants to have a medium to grow in that provides water, minerals and nutrients to allow for the photosynthetic growth. Next time we are going to talk about the Nitrogen Cycle and how much of a key role it takes. I would like to send a special thanks to COAL Photography. Click here to subscribe to his channel.

"Weathering" is the breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters. Weathering occurs "in situ", roughly translated to: "with no movement" , and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations. Two important classifications of weathering processes exist – physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. The second classification, chemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals also known as biological weathering in the breakdown of rocks, soils and minerals. While physical weathering is accentuated in very cold or very dry environments, chemical reactions are most intense where the climate is wet and hot. However, both types of weathering occur together, and each tends to accelerate the other. For example, physical abrasion decreases the size of particles and therefore increases their surface area, making them more susceptible to rapid chemical reactions. The various agents act in concert to convert primary minerals to secondary minerals and release plant nutrient elements in soluble forms.

Presented by Kristine Nichols, Ph.D., Soil Microbiologist, USDA Agricultural Research Service Soil as the heart of the farming ecosystem is driven by biological activities to increase soil organic matter, which represents a small percentage of the soil by weight, but controls over 90% of the soil functions. This presentation introduces viewers to the concepts of 1) rhizosphere biology, the area immediately surrounding the plant root with the highest concentration of microbiological activity; 2) soil "livestock" consisting of bacteria, fungi, nematodes, protozoa and microarthropods and representing the greatest concentration of biomass anywhere on the planet; 3) glomalin, a biological glue that holds soil together and improves soil aggregation; and 4) building soil biota to improve soil quality, increase nutrient cycling, and long term sustainability using cover crops, no-till, and other sustainable farming practices. The opinions expressed in this video are those of the presenter(s) and do not necessarily reflect the opinion of USDA.

Weathering involves the physical breakdown (disintegration) and chemical alteration (decomposition) of rock at or near Earth’s surface. Weathering goes on all around us, but it seems like such a slow and subtle process that it is easy to underestimate its importance. Yet weathering is a basic part of the rock cycle and thus a key process in the Earth system. Weathering is also important to humans— even to those of us who are not studying geology. For example, many of the life-sustaining minerals and elements found in soil, and ultimately in the food we eat, were freed from solid rock by weathering processes. There are three types of weathering process: Mechanical, Chemical and biological weathering When a rock undergoes mechanical weathering, it is broken into smaller and smaller pieces, each retaining the characteristics of the original material. The end result is many small pieces from a single large one. The picture below shows breaking a rock into smaller pieces increases the surface area available for chemical attack. An analogous situation occurs when sugar is added to a liquid. In this situation, a cube of sugar will dissolve much more slowly than an equal volume of sugar granules because the cube has much less surface area available for dissolution. Hence, by breaking rocks into smaller pieces, mechanical weathering increases the amount of surface area available for chemical weathering. Weathering can be accomplished by the activities of organisms, including plants, burrowing animals, and humans. Plant roots in search of nutrients and water grow into fractures, and as the roots grow, they wedge the rock apart. Burrowing animals further break down rock by moving fresh material to the surface, where physical and chemical processes can more effectively attack it. Decaying organisms also produce acids that contribute to chemical weathering. Where rock has been blasted in search of minerals or for road construction, the impact of humans is particularly noticeable.

Watch this one video and never forget what Hydrosere is. NEET Botany XII Ecosystem Biotic Succession in a Newly Formed Pond/ Lake (Hydrosere) Series of biotic communities that develop one after the other in a newly formed pond or lake is called hydrosere. Succession of plants in water habitat/ very wet habitat is called hydrarch. It starts as soon as the muddy water becomes clear. The various successional or seral stages of hydrosere are: 1. Phytoplankton Stage: It is the pioneer stage of hydrosere. Spores of this stage reach the water body through wind or animals. The first to appear are minute autotrophic organism called phytoplankton, e.g., diatoms, green flagellates, single-celled colonial or filamentous green algae as well as blue-green algae. They multiply rapidly. Soon a balance is created by the appearance of zooplankton which feed on phytoplankton. Death and decomposition of plankton produce organic matter. The latter mixes up with clay and silt at the bottom to form soft mud favourable for growth of next seral stage. 2. Submerged Plant Stage: The bottom lined by soft mud having organic matter is favourable for growth of submerged plants like Hydrilla, Potamogeton and Najas. They are rooted in the mud and form dense growth. As a result, sand and silt get deposited around the plants. This enriches the newly built up bottom and makes it favourable for growth of next stage. 3. Submerged Floating Plant Stage: Floating leaved, anchored plants (e.g., Nymphaea, Nelumbo and Nuphar) appear where water becomes shallow. These plants have subterranean stems like rhizome and tuber. The plants make the water rich in mineral and organic matter. It becomes suitable for growth of free floating plants like Lemna, Spirodela, Wolffia, Azolla, Eichhornia, etc. Rapid growth of floating stage further builds up bottom so that water becomes shallow on the periphery. 4. Reed-Swamp Stage: Amphibious plants grow where the water body becomes shallow (0.3-1.0 m), e.g., Phragmites, Typha, Scirpus, Sagittaria. The plants of swamp stage transpire huge quantities of water. They also produce abundant organic matter. 5. Sedge or Marsh-Meadow Stage: The shores built up by reed swamp stage are invaded by Carex (Sedge), Cyperus, Juncus, Grasses, Polygonum. The plants transpire rapidly and add abundant humus. Therefore, soil is build up to invite next stage. 6. Shrub Stage: The periphery of sedge meadow stage is invaded by some rhizome bearing shrubby plants which can tolerate bright sunlight as well as water logged conditions, e.g., Camus (Bogwood), Cephalanthus (Button Brush), Populus (Cottonwood) and Alnus (Alder). The plants of woodland stage lower the water table by their transpiration. They also built up more soil. 7. Climax Forest: New trees invade the area. They have shade loving seedlings. These trees grow to greater heights. The trees and shrubs of woodland stage disappear. The climax forest depends upon the climate – rain forest in moist tropical area and mixed coniferous or deciduous forest in temperate area. The species composition at the climax stage is determined by the regional climate, as well as local condition of soil, topography and water availability. The climax stage reflects the highest level of vegetation and associated fauna that can be supported under the given environmental condition. With time, both xerophytic habitat and hydrophytic habitat get converted into mesophytic one. Hydrarch and xerarch lead to medium water conditions (Mesic habitat).

Bioturbation is the mixing of (plant) residues into soils and sediments by biotic activity. It is one of the fundamental processes in ecology, as it stimulates decomposition, creates habitats for other (micro)fauna and increases gas- and water flow through the soil. Here you can see a system without (left) and with (right) soil fauna such as earthworms, potworms, collembola, mites and isopods over a 15 weeks period. The content of the left compartment was heated in an oven, removing the fauna but fungal spores survived. During this period, whereas only small fungal activity can be seen on the left side, the layer of leaves on the right side is almost completely incorporated in the soil due to the interaction between microbes, microfauna and mesofauna.

It is widely accepted that the occurrence of methane (CH4) in the Martian atmosphere may imply the presence of active geological sources, i.e. gas emission structures in the Martian soil and subsoil. In other words, gas seepage, a process well known on Earth, should exist on Mars. The concept of gas seepage,although obvious for many geologists, especially those working in gas geochemistry and petroleum geology, is ignored or poorly known by Mars methane science community. The seminar will offer a discussion on the fundamentals of seepage, its potential occurrence on Mars (via microseepage, mud volcanoes, faults, degassing from serpentinized rocks) and possible detection techniques. Basic concepts on potential methane origin on Mars (biotic vs abiotic) will be discussed and clarified, considering some confusion and misinterpretations in present literature. Giuseppe Etiopeis a senior researcher, geologist, at the Istituto Nazionale di Geofisica e Vulcanologia in Rome, Italy. He works on the origin, occurrence, and migration of gas in the geosphere, with particular reference to biotic hydrocarbons in sedimentary basins and abiotic gas in serpentinized ultramafic rocks. He studies the origin of methane, gas seepage phenomena and their implications for the environment, energy resource exploration and planetary geology (methane on Mars). He published 164 articles and a Springer’s book on “Natural Gas Seepage”. H index: 27 (Web of Science); 32 (Google Scholar).

What is BIOTIC MATERIAL? What does BIOTIC MATERIAL mean? BIOTIC MATERIAL meaning - BIOTIC MATERIAL definition - BIOTIC MATERIAL explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Biotic material or biological derived material is any material that originates from living organisms. Most such materials contain carbon and are capable of decay. The earliest life on Earth arose at least 3.5 billion years ago. Earlier physical evidences of life include graphite, a biogenic substance, in 3.7 billion-year-old metasedimentary rocks discovered in southwestern Greenland, as well as, "remains of biotic life" found in 4.1 billion-year-old rocks in Western Australia. Earth's biodiversity has expanded continually except when interrupted by mass extinctions. Although scholars estimate that over 99 percent of all species of life (over five billion) that ever lived on Earth are extinct, there are still an estimated 10–14 million extant species, of which about 1.2 million have been documented and over 86% have not yet been described. Examples of biotic materials are wood, linoleum, straw, humus, manure, bark, crude oil, cotton, spider silk, chitin, fibrin, and bone. The use of biotic materials, and processed biotic materials (bio-based material) as alternative natural materials, over synthetics is popular with those who are environmentally conscious because such materials are usually biodegradable, renewable, and the processing is commonly understood and has minimal environmental impact. However, not all biotic materials are used in an environmentally friendly way, such as those that require high levels of processing, are harvested unsustainably, or are used to produce carbon emissions. When the source of the recently living material has little importance to the product produced, such as in the production of biofuels, biotic material is simply called biomass. Many fuel sources may have biological sources, and may be divided roughly into fossil fuels, and biofuel. In soil science, biotic material is often referred to as organic matter. Biotic materials in soil include glomalin, Dopplerite and humic acid. Some biotic material may not be considered to be organic matter if it is low in organic compounds, such as a clam's shell, which is an essential component of the living organism, but contains little organic carbon.

The phosphorus cycle is the slowest one of the matter cycles that are described here. Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts that are released from rocks through weathering usually dissolve in soil water and will be absorbed by plants.

Decomposition Of Organic Matter | For Kids LINK THE GAME: http://pbskids.org/plumlanding/games/break_it_down/ The breakdown of organic matter is an important process that relates the dynamics of the vegetation with the dynamics of the soil. Regulating this process involved Biotic and abiotic factors. Some authors mention that temperature is the most important climatic factor, especially in very humid conditions; While other authors ensure that moisture is the most important climatic factor. However, it is clear that in temperate zones, the decay rate is lower than in tropical areas. Models have also been developed that They predict the content of organic matter and nitrogen in surface soils, based on information on average annual temperature and a "moisture factor ". Also others have developed models that predict the rate of decomposition based on the percentage of lignin contained in the foliage. The current annual Evotranspiración, without However, it presents regression curves more adjusted to the prediction model, being the most important factor.

011 - Biogeochemical Cycles In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water cycle, carbon cycle, nitrogen cycle, phosphorus cycle, and sulfur cycle. Do you speak another language?
