The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (Borago officinalis L.). To evaluat...

The Brazilian poultry industry generates large amounts of organic waste, such as chicken litter, which is often used in agriculture. Among the bacteria present in organic fertilizer are members of the Enterobacteriaceae family. The objective of this study was to detect the presence of diarrheagenic Escherichia coli (DEC) strains in avian organic fertilizer, and assess the potential damage they ...

regard to increasing demand for organic agricultural products, awareness of costs and profitability of organic products can help to decision planners of agricultural sector, and particularly farmers. this study has tried to calculate cost and profitability of cotton product in two different conventional and organic ways (procedure) of production using 253 cross-sectional data from khorasan raza...

Anaerobic digestion is a process in which microorganisms degrade organic material, such as dairy manure, in the absence of oxygen to produce biogas and digestate. Biogas is composed mostly of methane, which is the main constituent of natural gas (Table 1). Digestate is the degraded organic material that exits the digester after the digestion process. Digestate contains nutrients that can be use...

Different organic materials possessing antimicrobial properties have the ability to retard nitrification. Nitrification retarders could be successfully used to improve fertilizer efficiency if the retarders do not increase ammonia volatilization as well. The main objective of this study was to find whether any locally available organic materials namely cow dung, seed crush of Syzygium cumini, L...

in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and seed oil content of sesame an experiment was conducted in a split plot layout based on randomized complete block design with four replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2006. four types of fertilizer, including chemical fertilize...

this research was carried out for the purpose of urea fertilizer, organic matter and pgpr bacteria effects on yield and some growth indices on winter wheat (triticum aestivum c.v alvand). this research was carried out with factorial experiment on completely randomized design with 4 replication in greenhouse. treatments included bacteria 4 levels, without bacteri, a. brasilense, a. chroococum, i...

value of the current global soil P resource is appreciating the range of complexed P forms in soil and their specific issues for crop P accessibility. Soil organic P is especially poorly considered in terms of amounts and future utility. Learning to better utilize all of the different residual P forms in soil is essential to providing a sustainable cycle between agricultural inputs and plant up...
