Full-scale anaerobic digestion of pig manure often resulted in liquid effluents with considerably high organic matter, ammonia and phosphates content. If not enough agricultural land is available, the disposal of this effluent requires additional treatment. Different process scheme for reduction of the organic matter and nutrients from thermofilically digested pig manure were tested in full-sca...

In this study, poultry manure compost and organic fertilizer were added to soils derived from basalt, granite, and river alluvial deposits for use as soil parent materials. Following incubation periods of 30 or 60 days at 25 °C, the physical and chemical properties and adsorption characteristics of the soils were studied. The results indicated that the application of poultry manure compost or o...

abstract cumin is one the most important medicinal plant in iran. a field experiment was conducted in order to evaluate the effect of compost (30t/ha), vermicompost (10t/ha), cow manure (30t/ha) and sheep manure (20t/ha) and control (no fertilizer) on yield and yield components of cumin. the experiment was performed in the research farm of faculty of agriculture, ferdowsi university of mashhad ...

in order to study impacts of organic manure levels and inoculation with mycorrhiza fungi on growth, quantitative and qualitative yield of hyssop (hyssopus officinalis l.), a field experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2009-2010 a...

this study was conducted during 2008-2009 to investigate the influence of different organic nutrient combinations on yields and quality of strawberry cv. kurdistan in iran. the experiment comprised of five organic nutrient treatment combinations including the recommended dose of n, p and k through chemical fertilizer as control. treatment n2 (manure+azotobacter+ woodash+phosphorus solubilizing ...

the use of organic fertilizer brings about an increase in the organic matter of soil and the microbiological activities. generally as the soil in many parts of iranis poor, the use of manure is suggested for improvement of soil structure and physical and chemical properties to increase yield and to reach a sustainable agriculture. this investigation was conducted during 2001-2004 in karaj at th...

Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...
