Organic waste materials are being used in huge amounts (tons ha) for improving soil health and crop yields. Recycling of organic wastes enriched with nitrogen and L-tryptophan (L-TRP) could convert organic waste material into a useful soil amendment, which may be effective even when added in substantially small amounts (kg ha). Organic waste material of fruits and vegetables was collected and s...

Construction in urban areas usually results in compacted soil, which restricts plant growth and infiltration. Nutrients may be lost in storm runoff water and sediment. The purpose of this study was to determine if existing lawns benefit from aeration and surface compost additions without the negative impact of nutrient loss in runoff. Four sets of lawns were compared, with or without compost pl...

HE TREND toward composting reached its peak in Switzerland in 1975 when approximately 10 percent-or over 200,000 tons-of garbage were composted. However, as garbage production per capita and per year increased ;gin 1960 to 430 kg in 1987, cheminination also accelerated. This led to concern about excessive pollutants in compost and their impact on human health and the environment. Switzerland's...

Two greenhouse experiments were conducted to examine the effect of Crotalaria juncea amendment on Meloidogyne incognita population levels and growth of yellow squash (Cucurbita pepo). In the first experiment, four soils with a long history of receiving yard waste compost (YWC+), no-yard-waste compost (YWC-), conventional tillage, or no-tillage treatments were used; in the second experiment, onl...

compost is one of the strategies of house hold solid wastes management that is used to decrease the volume and weight of wastes, odor and leach ate dispersion, resource recycles and decreasing disposal expenses. in order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of environmental impact of composting plants has be...

Araucaria excelsa L. of Araucariaceae family is a beautiful conifer which has a high economic importance in the flower industry. A factorial experiment based on randomized completely block design with two factors: 1. Irrigation intervals in 2, 4 and 6 days (I1, I2 and I3) and 2. The growth bed in pots 3 L included M1 (100 % v/v cocopeat), M2 (100%  municipal waste compost), M3 (100 % vermicompo...

municipal solid waste compost (mswc) has been reported to improve soil fertility, plant development, yield and quality. polycyclic aromatic hydrocarbon (pah) is produced during the composting process which may cause cancer if introduced in human diet. an experiment was conducted at the experimental field of the agronomy faculty, university of guilan, rasht, iran, in 2008, to determine the effec...

This study aims to assess the effect of EM application on the composting process of rice straw with goat manure and green waste and to evaluate the quality of both compost treatments. There are two treatment piles in this study, in which one pile was applied with EM and another pile without EM. Each treatment was replicated three times with 90 days of composting duration. The parameters for the...

Introduction During this research project, we attempted to identify and overcome barriers and resistance to the establishment of organic waste (leaf and yard waste and food waste) collection and diversion programs within public and private institutions in the region that generate large amounts of organic wastes. As only 2.4% of food waste (EPA 1997) is recovered or recycled, there is 97.6% of f...
