  • Use of vermicomposting biotechnology for recycling organic wastes in agriculture

    Recent trend of declining sustainability in agricultural production is appearing as a major threat to most of the Asian countries. To combat the situation, increasing importance is now being paid on incorporation of organic materials for rejuvenating the health condition and, hence, the productivity of these soils. Large scale availability of conventional organic manures being a big problem ...

  • A systematic overview of urban agriculture in developing countries from an environmental point of view

    Urban agriculture can contribute to food security and poverty alleviation in developing countries. It can also help to improve public health and resource management by reusing excreta, wastewater and organic solid waste.

  • Database “organic and mineral residues”

    In the spirit of the material recycling concept in Germany (KrW-/AbfG, 1994), wastes are to be recycled as completely as possible, avoiding any impairment for mankind and the environment. In this connection, avoidance of material burdens by excessive nutrient and pollutant discharge is particularly important in the treatment, recycling and bringing into circulation of waste materials for re-use ...

  • Introduction of composted digestates in agriculture

    Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

  • Performance analysis of a co-gasifier for organic waste in agriculture

    Background:Agricultural waste has been proposed as an alternative energy resource to meet fossil fuel crisis, green house emission, and other environmental impacts worldwide. In Iran, rice husk and bagasse are main resources of biomass which can be used to produce syngas. This paper deals with a simplified model of combined gasification of coal and biomass processes considering chemical ...

  • Value of composted organic wastes as an alternative to synthetic fertilizers for soil quality improvement and increased yield

    One of the major problems with agricultural soils in the tropical region of the western Pacific islands is their low organic matter content, which results from rapid decomposition due to the hot and humid environment. Composted organic material is frequently applied on agricultural fields as an amendment to provide nutrients and also to increase the organic matter content and to improve the ...

  • Uncertainties in current knowledge of atmospheric trace gases associated with US agriculture

    Approximately 80 different crop species are grown in the United States in widely differing geographic areas, climatic and edaphic conditions, and management practices. Although the majority of cultivated acreage in the United States is planted with only about 10 primary crops, uncertainties associated with trace gas emissions arise from: (1) limited data availability, (2) inaccurate estimates ...

  • Organic amendment of an ultisol: effects on soil properties, growth, and yield of maize in Southern Guinea savanna zone of Nigeria

    Background:The Southern Guinea savanna zone of Nigeria is characterized by inherently low soil fertility status and rapid nutrient depletion especially soil organic matter. However, this zone is characterized by abundant agricultural land and is a potential for crop production. Field experiments were conducted in order to evaluate the effects of integrated use of agricultural waste materials and ...

  • Earthworms helping economy, improving ecology and protecting health

    Earthworms can treat organic garbage, livestock manure and poultry droppings and turn them into premium organic fertilisers, because humus only exists in earthworm feces and castings, compared with other fertilisers. Earthworms can also supply quality animal protein as feed, and offer the best raw materials for the biochemical and pharmaceutical industries. Vermiculture should be put into a whole ...

  • Microbial biomass c and ninhydrin-reactive n as Parameters to characterize composting process

    The use of compost in agriculture is increasing as a source of organic matter to counteract the decrease of organic matter level in soils and as a means of disposal of agricultural and domestic waste. Despite many researches on the subject, there is still the need to improve our knowledge on the compost process and on the methods to evaluate compost maturity. The composting of organic waste has ...

  • Building state’s compost markets

    Several research projects now under way have the potential to significantly expand the compost market in California. Californians generate 93 million tons of solid waste annually. The Integrated Waste Management Act of 1989 (AB 939) established the CIWMB and gave it the responsibility to oversee, manage and track all of this material. Expanding the opportunities for composting organic materials ...

  • Model-based investigations into long-term compost application effects on nitrate leaching at different agricultural sites

    Organic waste materials may beneficially be used for fertilisation as well as for soil improvement on agricultural sites after composting and subsequent application. If compost is continuously applied at an annual scale of app. 10 Mg dry matter/ha, the content of organic matter in the soil will increase in the long-term, as shown in a field trial in Neu-Eichenberg, conducted 1985-97 by Univ. of ...

  • The CAMBI process and agriculture, a sustainable solution?

    Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...
