A study was carried out on the sorption of the sparingly water-soluble pesticide linuron in various types of soil with different levels of organic matter. The sorption isotherms of the pesticide were obtained in bathequilibrium experiments and the data were fit to Freundlich and Dual Reactive Domain Models. In general, the sorption was the highest for the soil with greatest content of soil orga...

Five treatments were compared using two half-highbush blueberry cultivars (cv Chippewa and Polaris) transplanted and grown for their first three growing seasons at a site in Boutiliers Point, N.S., a Gibraltar brown sandy loam (Ferro-Humic Podzol). The five treatments were as follows: Alfalfa meal + rock P + wood ash; NPK fertilizer; Municipal Solid Waste (MSWC) compost; Ruminant compost; food ...

Composting is a reliable technology for production of stabilized organic matter that is suitable for agriculture, but this process should be carefully monitored with appropriate indices. Quality of compost is important from maturity and stability viewpoint, but in most compost factories proper attention is not paid to it. This study was designed to evaluate the stability indices in municipal so...

Fresh mushroom compost is a byproduct of the edible mushroom (Agaricus bisporus) industry and represents the composted growing substrate that remains after a crop has been harvested to completion. Thirty samples were obtained from commercial mushroom farms in southeastern Pennsylvania and sent to a laboratory for analysis to determine plant nutrient content, bulk density, and particle size dist...

Composting of Palm Oil Mill Sludge (POMS) with sawdust was conducted in natural aerated reactor. Composting using natural aerated reactor is cheap and simple. The goal of this study is to observe the potential of composting process and utilizing compost as media for growing Cymbopogun citratus, one of Malaysia herbal plant. The highest maximum temperature achieved is about 40 degrees C and to i...

Changes in physical and chemical characteristics of an organic waste (tomato crop waste) throughout composting (COM), vermicomposting (VER) and the combination of both processes (C+V) were assessed at five selected stages. COM consisted of a combination of the static Rutgers system with forced aeration and pile turning. For VER Eisenia worms were fed with the raw material. For C+V pre-composted...

Introduction: In Tehran with a population of 9 million currently, about 2.5 million tons municipal solid waste have been producing annually. Materials and Models: In this study by using Life Cycle Assessment (LCA) model an optimal system of waste management of Tehran was recommended. Based on the quantity and quality of waste in Tehran in 2013 and facilities, three scenarios were selected. Fir...

BACKGROUND Compost habitats sustain a vast ensemble of microbes specializing in the degradation of lignocellulosic plant materials and are thus important both for their roles in the global carbon cycle and as potential sources of biochemical catalysts for advanced biofuels production. Studies have revealed substantial diversity in compost microbiomes, yet how this diversity relates to functions...
