Organic agriculture is an ecological production management system aimed at sustainableproduction of safe food, environmental protection and maintenance of soil health. The objectiveof this study was to evaluate, in a period of organic transition, the effects of different organicfertilizers on wheat yield, grain quality and soil characteristics. The research was performedin an experimental farm ...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

One of the most effective ways of recycling the organic and mineral fractions of sludge from the treatment of domestic wastewater is to compost the sludge with the organic fraction of domestic refuse. In the present study, a compost on a semi-industrial scale was obtained from a mixture of domestic refuse and sewage sludge. The evolution of the different parameters throughout the process was no...
