Evolution of Biochemical Parameters During Composting of Urban Wastes
|
An experiment was performed for evaluating the most suitable biochemical parameters to measure dynamics of substrate transformation during composting of the organic fraction derived from preselected urban wastes and wood bark mixture. Changes of chemical (organic C, hydrosoluble sugars, total and mineral N, humified fraction, volatile acids and phenolic compounds) and biochemical (microbial respiration, biomass C, qCO^sub 2^, dehydrogenase, catalase, urease activities, FDA, and BIF) parameter...

Stabilization of Organic Matter During Composting: Influence of Process and Feedstocks
Compost Science & Utilization
; Information on compost organic matter stability is necessary to anticipate the effects of compost application on soil properties. Such information will soon be required by French legislation. The main objectives of the present work were: (1) to study the influence of the composting process and the

Organic Matter Fractions Involved in Degradation and Humification Processes During Composting
Compost Science & Utilization
; The changes in the different organic matter (OM) fractions of lignocellulosic wastes during composting were studied and related to OM humification parameters and compost maturation degree. For this purpose, four mixtures of lignocellulosic materials (lemon tree prunings, cotton waste, brewery

Organic Matter and Nitrogen Conservation in Manure Compost for Organic Agriculture
Compost Science & Utilization
; Compost is a main source of organic matter (OM) and of nitrogen for organic farming in arid and semiarid regions. An effort has been made to reduce nitrogen loss during composting of separated cow manure (SCM) using high C / N additives - wheat straw, (WS), grape marc (GM) and slightly acidic

Composting Olive Mill Waste and Sheep Manure For Orchard Use
Compost Science & Utilization
; An industrial-scale composting plant has been designed for producing organic fertilizers from olive mill waste using the windrow pile system. Materials to be composted, two phase olive mill waste (TPOMW) and sheep litter (SL), were characterized and made into three piles consisting of different

Conserving nitrogen during composting
BioCycle
; IMPROVING MANURE COMPOST Adding carbonaceous materials to cow manure under moderate composting temperatures can produce higher N and organic matter content. DURING the course of aerobic composting, much of the initial nitrogen content in feedstocks may be lost. According to the research literature,

Saving the life of farmland soils: aware of a remorseless decline in the vital organic matter of Australian farmland soils because of land clearing and agricultural production, researchers, land managers and now, commercial players, are seeking ways to reverse the trend. It's an important quest:without organic matter, soil is essentially sterile, reducing the viability of both agricultural and surrounding natural systems.(SOIL CARBON: Focus)
