The effects of compost based substrates on growth and nutrition of geranium (Pelargonium zonale cv Lucky Break F2) were investigated. Substrates of manure compost, cotton gin trash compost, municipal solid waste compost and pine bark utilized as potting media for domestic use, produced an underdevelopment of geranium plants with respect to the control. This behaviour is related to the inferior ...
Background and purpose: In spite of many studies on composting from municipal solid wastes, rural solid wastes have not been studied. A high percentages of rural solid wastes containing domestic, animal and agricultural solid waste is biodegradable. The objective of this research was to study the chemical and microbial quality of compost produced by mixed rural solid wastes and other composts...
The effect of successive applications of urban compost (up te 150 and 400 t ha-1 during eight years) en the status ef phosphorus in a calcareous soíl (20%) was testad in a greenhouse experimento An 6-15-15 complex fertiliser was also applied for comparison. Five years of ryegrass and three of horticultural plants (tomate and eggplant) were successively cropped during the experimento Increases o...
We studied the effects of applying different composts (urban organic waste, green waste, manure and sewage sludge), mineral fertilizer and compost plus mineral fertilizer on chemical, biological and soil microbiological parameters over a 12-year period. The organic C and total N levels in soils were increased by all compost and compost + N treatments. Microbial biomass C was significantly (P £ ...
Background and Objectives: The quantitative and qualitative data on urban solid waste is one of the essential steps in the scientific management of solid waste. The purpose of this study was to survey the qualitative and quantitative production of solid waste in Mashhad. Materials and Methods: In this descriptive study, in order to examine the quality of the samples, the separated materials we...
UNLABELLED Poor solid waste management is among the major challenges facing urban slums in developing countries including Uganda. Understanding community concerns and willingness towards involvement in solid waste management improvement initiatives is critical for informing interventions in slums. METHODS We used a cross-sectional study to collect quantitative data from 435 residents in two u...
Application of bio-fertilizers and organic compounds is a way to reduce the use of chemical fertilizers. In order to study the effects of organic compounds and phosphate bio-fertilizer on some quantitative and qualitative attributes of ivy geranium (Pelargonium peltatum), a factorial experiment based on randomized complete blocks design (RCBD) was carried out using two factors including phospha...
the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...
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...
