Influence of Ash Applied to Oat Crop (Avena sativa L.) Grown under Organic Fertilization with Manure
Keywords:
manure, oat biomass, power plant ashAbstract
The power plant ash is an inorganic residue with a variable chemical buildup according to the type of charcoal used and quality. Depositing, stabilizing and eventually reintegrating the ash in the natural circuit raises a series of problems due to its disastrous effect on biodiversity. Even with these problems, at a moderate micro and macro mineral content, power plant ash could present interesting agro technical and ecological alternatives. For this reason, the controlled integration of ash could put a stop to pollution with ash by reintegrating the material in the agricultural ecosystems.
For this purpose, in the field of research of Ecological and Forage Crops from Faculty of Animal Science and Biotechnologies Timisoara, research was conducted over the influence of the reintegration of 40 t of ash per ha, produced by C.E.T. Timisoara, on the biomass production of oatmeal (Avena sativa L), fertilized by levels of 25 and 50 t per ha of manure. After harvesting, the analysis of the total biomass quantity, both above and underground, revealed similar results in all trials. In conditions that include heavy metal concentrations beneath normal geological values, conclude that the application of 40t per ha may be an agro technical solution for the integration of power plant ash in the agricultural ecosystem.
