soil | Definition, Importance, Profile, Composition compost description composition process britannica

Soil, the biologically active, porous medium that has developed in the uppermost layer of Earths crust. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of wastes, and as a participant in the cycling of elements.soil - Students | Britannica Kids | Homework HelpComposition of Soil Soils are composed of mineral matter and organic matter and contain pore spaces filled with water or air and soluble nutrients. Organic matter serves as a binder for mineral particles, contributing to good soil structure and tilth, which refers to the behavior of soil under cultivation.soil - Kids | Britannica Kids | Homework HelpDifferent types of soil contain different mixtures of clay, silt, and sand. The organic part of soil forms when plants and animals die. Their bodies decay, or break down, and mix with the rock particles. The organic material, called humus, helps to form the pores in the soil.

peat | Description, Formation, & Uses | Britannica

Peat, an organic fuel consisting of spongy material formed by the partial decomposition of organic matter, primarily plant material, in wetlands. The formation of peat is the first step in the formation of coal. Peat is only a minor contributor to the world energy supply.humus | National Geographic SocietyJan 31, 2011 · Humus is dark, organic material that forms in soil when plant and animal matter decays.. When plants drop leaves, twigs, and other material to the ground, it piles up. This material is called leaf litter.When animals die, their remains add to the litter. Over time, all this litter decomposes. This means it decays, or breaks down, into its most basic chemical elements.composting toilet | Description, Uses, & Process | BritannicaComposting toilet, also called biological toilet or dry toilet, waterless sewage-treatment system that decomposes human excreta into an inert nitrogen-rich material similar to humus. Because they eliminate the water use associated with typical toilets, composting toilets circumvent the costs associated with traditional sewage treatment.

compost | Description, Composition, & Process | Britannica

Composts commonly contain about 2 percent nitrogen, 0.51 percent phosphorus, and about 2 percent potassium. Nitrogen fertilizers and manure may be added to speed decomposition. The nitrogen of compost becomes available slowly and in small amounts, which reduces leaching and extends availability over the whole growing season.chemistry - Students | Britannica Kids | Homework HelpEncyclopædia Britannica, Inc. Word description: Two molecules of ammonia react with each other to form one molecule of nitrogen and three molecules of hydrogen. Chemical equation: 2NH 3 N 2 + 3H 2.

Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Learn more about cement in this article.

antibiotic | Description, Uses compost description composition process britannica - Britannica

Antibiotic, chemical substance produced by a living organism, generally a microorganism, that is detrimental to other microorganisms. Antibiotics came into worldwide prominence with the introduction of penicillin in 1941. Since then they have revolutionized the treatment of bacterial infections.Windrow Composting Process, Composting Organic Wastes Outdoor composting in piles that rely on mechanical aeration, typically with a compost windrow turner, to optimize the composting process. Allance compost turner machines are very efficient, which makes the whole composting process fast, high-rate, and capable of rapid degradation and stabilization of almost all organic materials.Why is windrow composting important? Windrow turning is important for speeding up the composting process because it breaks preferential air pathways, and brings the material from the outside to the center for pathogen kill. Windrow composting is a suitable option for manure management, reducing risks of odor, soil and water pollution.See all results for this question

Why is compost so important?

Why Compost? Compost helps the soil retain moisture and adds nutrients, which means you can use less fertilizer and water. It also encourages beneficial bacteria and fungi to breed and do their job breaking down organic matter. Basically, it contributes to the soil food environment so plants can more efficiently take up nutrients.See all results for this questionWhat is Topsoil? - Definition, Composition & Uses - Video compost description composition process britannicaTopsoil, classified as the A or the O horizon of soil, is the part of the soil where all of the biological activity happens.

Vermicomposting - an overview | ScienceDirect Topics

Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like material known as vermin-compost. The goal is to process the material as quickly and efficiently as possible. Vermicompost appears to be generally superior to conventionally produced compost in a number of important ways:Types Of Soil - Sandy Soil, Clay Soil, Silt Soil, And compost description composition process britannicaSoil can be classified into three primary types based on its texture sand, silt and clay. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc. 2. State the characteristics of sandy soil. Sandy soil essentially consists of small particles formed by weathering rocks.The Composting Process - uidaho.eduTHE COMPOSTING PROCESS 3 WHAT IS THE NUTRITIOUS MICROBIAL FOOD? During composting, microbes break down organic compounds to obtain energy to carry on their life processes and acquire nutrients (N, phosphorous, potassium) to sustain their populations. Of the many elements required for microbial decomposition, C and N are the most critical. No trace
