A cellulolytic, thermophilic actinomycete (previously isolated from municipal refuse compost samples) was identified as Thermomonospora curvata. A determination was made of the optimal conditions for cellulase production by T. curvata when grown at 55 C in a medium containing mineral salts, cellulose, and yeast extract. The pH and temperature optima (pH 6.0 and 65 C) for the cellulase produced ...

A two-year field experiment was carried out to investigate the effects of nitrogen, composted manure, municipal waste compost, and weeds on yield and photosynthetic characteristics of corn. Experimental design was split split plot factorial with 3 replications. Main plots were weedy and weed-free, sub plots were nitrogen fertilizer levels [0 (N0) and 200 (N200) kg N ha -1 as urea], and sub sub ...

in order to study the influence of municipal waste compost and chemical fertilizer on yield and yield components in maize (zea mays l.) an experiment was conducted at research farm of sari agricultural sciences and natural resources university during 2007. the experiment was arranged in split plots based on complete randomized block design with two factors and three replications. main plot incl...

A stable compost is needed in plant growth media. However, when compost is land applied, its effect is through the initiation and acceleration of microbial processes leading to the production of soil stabilizing agents. It was proposed that there is an optimum degree of maturity of compost used for land application, a degree characterized by the reduction of the labile organic matter to a point...

abstract incorporation of plant residues in soils is an important agricultural practice for maintaining soil fertility under organic management systems. plant residues quality, soil physical and chemical properties, and the microbial population diversity of soils are the most important factors influencing the decomposition of added organic matter to soils. decomposition rate of municipal wastes...

in order to studying the effect of conventional fertilization and organic fertilizeron growth, yield and nitrate accumulation of spinach, a greenhouse experiment was carried out in factorial based on random complete design with three replications in a commercial greenhouse located at lahijan. treatments were three levels of municipal soil waste compost (0, 50 and 100 t ha-1), five chemical fert...

in order to study the effects of drought stress and municipal compost on quantitive characteristics in peppermint , a green house experiment in a factorial based on a randomized complete block design with four replications was conducted in 2009 at university of zabol. treatments included: three irrigation levels %100 field capacity(control),%80 field capacity(mild stress) and %60 field capacity...

An experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. The treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. The results revealed that the ...

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...
