Introduction Vermicomposting could increase nutrients availability including phosphorus. During vermicomposting, a decomposition of organic substrates leads to the production of several organic acids, such as malonic, fumaric, succinic acids. Microorganisms both in the intestinal organ of the worms and the organic waste have the ability to convert insoluble P into soluble forms. Little information exists […]
Background Recycling of crop residues is essential to sustain soil fertility and crop production. Therefore, it is of crucial importance to study the decomposition of crop residues particularly in the arid tropics. The decomposition and nutrient release pattern from crop residues incorporated in the soil have rarely been investigated under semiarid climatic conditions in Sudan. […]
Background Restaurant waste (RW) can be considered as a valuable feedstuff for animal nutrition due to its high nutritional value and low price. The aim of this study was to determine nutritional value and the microbial load of the waste in order to incorporate it in the poultry feedstuff. To our knowledge the current study […]
Background Water hyacinth (Eichhorniacrassipes) is one of the most uncompromising weeds in the whole world. Its adverse effects due to fast growth rate are main physical interference with fishing and navigation. Water hyacinth also causes eutrophication due to the large release of organic nutrients after its degradation, consequentially deterioration of water quality and also adversely […]
Background The disposal of sugar mill effluent has become a major problem in India due to generation of huge volume of effluent. The value of wastewater for crop production has been recognized in many countries, including India. The effluents not only contain nutrients that stimulate growth of many crops, but also may have various toxic […]
Introduction The Lusaka Water and Sewerage Company (LWSC) produces *800–1,000 kg of treated sewage sludge per day at its Manchinchi wastewater treatment plant (WWTP). The biosolids are used for land application purposes although the contaminant and pathogen composition and quality of the biosolids have been unknown until this study. Zambia does not have legal standards […]
There is a widespread interest in converting organic waste into compost fertilizer to extend the life of landfills, create economic and environmental benefits, and ultimately reduce the pressure on local governments in managing the ever-increasing complexity of municipal solid waste. However, composting is still seldom considered as a strategic element. There is also very little […]
Background This experiment was conducted to study the effect of diet contained mushroom spent wheat straw (MSWS) remained from Agaricus bisporus mushroom as well as the physical form of the diet on the performance of the feedlot calves. At the end of mushroom harvesting period, MSWS was collected from production room and the casing soil […]
Introduction In Europe, because of the high production levels of livestock farming in general and pig farming in particular, animal waste management has become increasingly important to comply with the required lowering of livestock farming environmental pressure. Usually manures undergo solid/liquid separation, which generates one clarified liquid fraction and one nutrient-rich solid fraction suitable for […]
Background The utilization of organic fertilizer is an effective method in organic culture of medicinal plants because of its beneficial effects on soil structure, reduction of environmental problem and improvement in plant growth. The experiments were conducted in a research field at the University of Guilan at the Rasht and Torbat-e-Jam Razavi Khorasan Province, Iran. […]
