DEWT/FT/1A/01 Aim: To determine the concentration of organic contaminants in soils by using the Loss in ignition method. Introduction: The quantity of organic matter in soil is determine by either direct or indirect methods. Direct method target the destruction of all organic matter‚ after which the loss in weight of soil is taken as the organic content. Two methods are commonly used to achieve destruction of organic matter: Oxidation of organic matter with hydrogen peroxide (H2O2). Ignition of

degradation of food scraps. The result of turning food scraps and organic garden waste into compost can help improve soil quality and garden vitality by releasing the rich nutrients and recycle valuable nutrients and therefore reduce the use of artificial fertilizers. Composting converts kitchen and garden waste or the food scraps into dark colored soil that is high in nutrients. Composting is the controlled decomposition of organic materials. Home composting is the natural degradation of yard trimmings

Tobacco Composting: An Alternative to Burning or Landfill Composting is the purposeful biodegradation of organic matter‚ such as yard‚ food and agro-industrial waste. The decomposition is performed by micro-organisms‚ mostly bacteria‚ but also yeasts and fungi. A biodegradable material is capable of being completely broken down under the action of microorganisms into carbon dioxide‚ water and biomass. A compostable material biodegrades substantially under specific composting conditions.

which is environment friendly. Essentially‚ a no-dig garden comprises layers of varying organic matter piled up. This allows the entire area to be accessed without walking on the garden‚ thus preventing soil compaction‚ which is detrimental to worm activity and healthy plant growth. The layers of a no-dig garden are similar to those of an efficient‚ fast-working compost heap. Using such a varied range of organic materials creates high nutrient levels and there should be very few weed seeds. Whereas

Leaves that fall into a stream create a significant impact on the energy flow and nutrient cycling of the stream’s ecosystem. Leaves provide an abundant amount of organic material for many of the organisms within the stream. Decomposed leaves are a particularly important carbon source for

Before I go on about the use of fertilizers in organic farming‚ you must first understand what organic farming is. The simplest way to describe organic agriculture is agricultural production without the use of synthetic chemicals (fertilizers‚ pesticides‚ antibiotics‚ etc). For crop production‚ organic materials such as compost and manure are used to maintain soil organic matter and as sources of nutrients. Nitrogen-fixing as well as pest resistant plant varieties are utilized. The incorporation

Organic food is defined as produce (animal and plant) that is grown without the aid of any chemicals or pesticides‚ this means the animals are fed organic feed and the plants are grown in a very different way to most foods we see at the supermarket. Many people purchase organic food because they think that the nutritional benefits will make up for the extra money that you spend. Lots of people say that the manufacturers of organic food lie to us when selling these products‚ they say that there aren’t
