this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...

Methane emission f rom l ivestock and agricultural wastes contribute globally more than 3 0 % to the anthropogenic atmospheric methane source. Estimates of this number have been derived f rom respiration chamber experiments. W e determined methane emission rates f rom a tracer experiment in a modern cow shed hosting 43 dairy cows in their accustomed environment. During a 24-hour period the conc...

• Gentamicin initially decreased microbial activity comparative to penicillin higher. Recovery was comparatively high in oxytetracycline treated soils. Organic amendments improved the resilience indices. Unexpectedly qCO2 antibiotic The static effects of applied antibiotics were higher than their cidal effects. This study aimed describe and adverse on soil resulting from manure application. So,...

Inadequate organic waste management can contribute to the spread of diseases and have negative impacts on the environment. Vermicomposting organic waste could have dual beneficial effects by generating an economically viable animal feed protein in the form of worm biomass, while alleviating the negative effects of poor organic waste management. In this study, a low-maintenance vermicomposting s...

so far, different methods have been applied to clean up soils contaminated with oil. bioremediation is one of the clean up technologies which uses microorganisms or microbial processes to degrade oil contaminations in soils. this study evaluates the applicability of cow manure as bioremediation alternative for soils spiked with petroleum hydrocarbons. target contaminant of this research was die...

The growing number of biogas plants in Europe has resulted in increased production of nutrient-rich digestate, which has potential as fertiliser on arable land. Many different organic materials can be degraded in the anaerobic digestion process, with most macronutrients and micronutrients retained in the digestate. Depending on the ingoing organic substrate and management of the biogas process,...

introduction: today, production of organic farming and gardening is rising. the use of organic fertilizers such as animal manure has a long history. in recent years, the use of fertilizers and manure for providing the nutritional needs of plants, improve soil physical and chemical structure and reduce the environmental issues have been observed. animal manures can increase soil organic matter a...

The use of swine manure as a source plant nutrients is one alternative to synthetic fertilizers. However, conventional application with >90% water and low C:N ratio results in soil C loss the atmosphere. Our hypothesis was biochar nutrient stabilizer that would slowly release plants upon biochar-swine mixture soil. objectives were evaluate impact biochar-treated on total C, N, plant-availabl...
