Due to the Earth’s population rapid growth and modern lifestyle, urban waste creation rate constantly increases.Organic waste, which forms a significant part of municipal solid has caused increasing environmental concerns. Recycling is only way make sustainable environment. According estimations from United States Environmental Protection Agency, around 24 percent total can be composted. Instea...

little information is available on the effects of applying compost tea to species in dry regions. compost from agricultural waste can promote drought resistance in plants and increase their growth by improving soil structure and providing nutrients and enhancing the capacity of the soil to store moisture. in order to examine these effects, compost tea was tested on two species growing in dry re...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated wi...

Pathogen contamination of waterways is a serious concern in dairy farming areas where livestock waste is applied to agricultural fields. As an alternative, a biodrying composting system dries collected livestock waste, reduces the strong odors, and has been proposed as a means of reducing, and even eliminating pathogens present in the waste. Therefore, the survival of pathogens in a biodrying c...

Home composting systems (HC) are known to facilitate municipal solid waste management, but little is known about their environmental impact including their greenhouse gas emissions (GGE). The present research focused on selecting HC configuration producing the least CH(4) and N(2)O. Thus, 4 HC types were used to compost food and yard waste for 150 days and monitored for CO(2), CH(4) and N(2)O a...

Recently problems relating to environmental pollution and the need to protect and preserve the environment from further deterioration has drawn increasing research attention. The goal of any remediation based on soil amendments is to achieve maximum reduction in the bioavailability of heavy metals by immobilization in soils. Modern remediation approaches increasingly focus on in situ environmen...

Landfilling is one of the most common ways of municipal solid waste disposal. Degradation of organic waste produces CH(4) and other landfill gases that significantly contribute to global warming. However, before entering the atmosphere, part of the produced CH(4) can be oxidised while passing through the landfill cover. In the present study, the oxidation rate of CH(4) was studied with various ...

casing material or soil (casing) is used in mushroom (agaricus bisporus) culture to cover a nutritional composted substrate colonised with mycelium, and has an essential function in stimulating and promoting the development of sporophores (fruit bodies). in order to use the agricultural by products (different wastes) to reduce peat consumption of casing soil in button mushroom production, an ex...
