Purpose Biogas residues, digestates, contain valuable nutrients and are therefore suitable as agricultural fertilizers. However, the application of fertilizers, including digestates, can enhance greenhouse gas (GHG) emissions. In this study different processes and post-treatments of digestates were analyzed with respect to triggered GHG emissions in soil. Methods In an incubation experiment, GHG emissions from two […]
Purpose Soil salinization is one of the most severe abiotic stresses which threaten sustainable agriculture in arid and semi-arid regions including Morocco. The application of organic amendments like composts to saline soils has been confirmed to alleviate soil salinity stress. The present work aims to study the effect of humic acids (HA), as one of […]
Purpose Food waste can be referred to as edible food materials that can create problems to the environment if it is not disposed properly. Therefore, the purpose of this study is to produce chicken feed from food waste via two-stage fermentation. Methods Food waste was converted with combination of fungi A (isolated from degraded onion) and yeast […]
Purpose The effect of using compost and vermicompost or their teas on the growth and biochemical profile of Salvia officinalis cultivated in sand soil were assessed. Methods Plants were subjected to different treatments of compost, vermicompost and their teas. The growth of common sage, Salvia officinalis was monitored as shoot fresh and dry weights (g/plant) and […]
Purpose The uncontrolled discharge of phosphorus into aquatic environment leads to the deterioration of the water bodies. Additionally, the agricultural crops present inside the La Albufera de Valencia Natural Park, rice fields mainly, have a high social and environmental value. However, there is a conflict between private interests (farmers) and public interest in the management of […]
Purpose The research was focused on evaluating phytotoxicity of sewage sludge from two selected wastewater treatment plants in Czech Republic. Methods Laboratory experiments were carried out with samples of sewage sludge, which were focused on the evaluation of their phytotoxicity by using the PhytotoxkitTM testing set. Specifically, the inhibitory/stimulating effect was established on the growth […]
Purpose To evaluate the feasibility of using biosolids and fly ash, processed through the Bokashi fermentation process, as growth promoters of maize. These two components were included because they are generated in large amounts and represent an environmental problem all over the world. Additionally, these materials have high concentrations of nutrients, but they have not […]
Purpose The objective was to evaluate the effect of the application of composted and non-composted poultry litter, as fertilizer in agricultural areas, on the survival and reproduction of the springtails (Folsomia candida) through standardized ecotoxicological tests. Methods The treatments included in the application of composted and non-composted poultry litter on Entisol were in the following […]
