Composting is a natural process that turns organic material into a dark rich substance called compost. Aerobic Composting is the creation of compost that depends on bacteria that thrive in an oxygen rich environment. Aerobic bacteria manage the chemical process by converting the inputs (i.e. air, water and carbon and nitrogen rich materials) into heat, carbon dioxide and ammonium. The ammonium ...

The effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. Experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). The study was performed in a randomized complete block design with 3 replicates. Results indicated that application of organic substances enha...

to evaluate the effect of different levels of nitrogen fertilizer and municipal compost on the essential yeild of savory pot experiment in 2009 was carried out in the darab region. different doses of compost was in four levels, including: zero c0:, 10c1:, 20c2: and 30c3: tons per hectare and nitrogen fertilizer include: zero n0:, 30n1:, 60 n2: and 90n3: kg of pure nitrogen from urea per hectare...

introduction during the last decades interest in organic production of seed specially for medicinal plants take into consideration because of higher quality of organic products (hermes, 2010). seed germination is one of the principal stages in the plant life cycle and seeds with higher quality and vigour resulted in more pronounced seedlings growth and development. therefore, investigation of a...

to investigate the effects of supplementary irrigation and application of different compost levels on morphological traits, yield and yield components of two chickpea cultivars under dry land conditions, a field experiment was conducted at the research field in khoramabad, iran in 2009-2010. the experiment was split split plot based on randomized complete block design with four levels of irriga...

The utilization of compost vineyard wastes as suppressive growing media against Fusarium wilt is a good alternative for the disposal and recycling of these organic wastes. Inoculation of biological control agents (BCAs) enhances the biocontrol activity of compost. In this experiment, vineyard compost was sampled at different stages during the composting process, rating the values of acceptabili...

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two compost on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasifi...

To Select an appropriate medium for the growth of plant is one of the problems of most greenhouse owners in production of pot ornamentals. So, current research was conducted to evaluate effect of some available media in mixtured by perlite on the growth of pothos. Study was based on a completely randomized design with 5 treatments, 8 measuring times and 6 replications in a fiberglass greenhouse...

Peat replacement is an increasing demand in containerized and transplant production, due to the environmental constraints associated to peat use. However, despite the wide information concerning the use of alternative materials as substrates, it is very complex to establish the best materials and mixtures. This work evaluates the use of mixture design and surface response methodology in a peat ...

Two experiments were conducted to evaluate different compost mixtures as peat substitutes, and the effect of Trichoderma and mycorrhiza fungi application on transplants quality. Seeds of commercial lettuce (Lactim sativa L.) and cabbage (Brassica oleracea), a nonmycotrophic plant were sown in 'Speedling' trays. Plant growth response was determined in four weeks old seedlings (commercial transpl...
