Thermal properties of compost bulking materials affect temperature and biodegradation during the composting process. Well determined thermal properties of compost feedstocks will therefore contribute to practical thermodynamic approaches. Thermal conductivity, thermal diffusivity, and volumetric heat capacity of 12 compost bulking materials were determined in this study. Thermal properties were...

COMPOST is the result of our first reflections on the computing requirements for synthetic speech generation. It combines the basic facilities of a rule-oriented software with object-oriented design. COMPOST is a tree compiler : it manipulates and transforms not only lists of atoms but also trees and subtrees. Basic atoms involved into the tree inherit of properties of user defined classes Feat...

We measured Escherichia coli, Enterococcus spp. and fecal coliform numbers in soil and on fresh potato skins after addition of solid dairy manure and dairy compost with and without alum (Al(2)(SO(4))(3)) treatment 1, 7, 14, 28, 179 and 297 days after application. The addition of dairy compost or solid dairy manure at rates to meet crop phosphorus uptake did not consistently increase E. coli and...

BACKGROUND In Iran, re-refinery industry has been developed many years ago based on the acid-clay treatment. Acidic sludge with high concentration of total petroleum hydrocarbon (TPH) is the final products of some facilities. In this study removal of TPH by aerated in-vessel composting was investigated. METHODS In order to microorganisms seeding and nutrient providing, urban immature compost ...

The objective of this series of studies was to investigate the use of compost and mulch materials in erosion control and stabilization projects. The first phase of the study primarily looked at the impacts of surface blankets of twelve different compost and mulch materials on total solids (TS) loss and water quality and found that mulch blankets produced runoff with the lowest TS and nutrient c...

We evaluated the abundance of microbial functional groups involved in compost fertility, and the chemical parameters of maturity and quality most commonly analyzed in compost products. We employed compost produced using the same hydrolytic stage and two maturation processes (with and without earthworms) and with different organic wastes. Our aim was to propose a valid tool for measuring the qua...

Improper use of urea may cause environmental pollution through NH3 volatilization and NO3 (-) leaching from urea. Clinoptilolite zeolite and compost could be used to control N loss from urea by controlling NH4 (+) and NO3 (-) release from urea. Soil incubation and leaching experiments were conducted to determine the effects of clinoptilolite zeolite and compost on controlling NH4 (+) and NO3 (-...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

Fertilization plays an important role in crop growth and soil improvement. This study was conducted to determine the best fertilization system for wheat production. Experiments were arranged in a complete block design with three replications in two years. Main plots consisted of six methods of fertilization including (N1): farmyard manure; (N2): compost; (N3): chemical fertilizers; (N4): farmya...
