CARMEN OTILIA RUSANESCU, EROL MURAD, COSMIN JINESCU, MARIN RUSANESCU THE IMPACT OF BIOCHAR ON THE SOIL In the present paper are presented the experimental results of biomass gasification, the biochair was produced from vineyards by controlled pyrolysis at 750 °C, in order to increase the fertility of soils, it was found the increase of the fertility produced by the development of the vegetables in the soil to which was added biochar. Soil was added to soil 4 g/dm3 biochar, 8 g/dm3 biochar, the soil had no high humidity, was taken at a time when it had not rained for at least one week, the soil pH was 8, in the soil with 8 g/dm3 biochar the plants increased compared to the soil with 4 g/dm3 and the soil without biochar. The biochar resulting from pyrolysis and gasification processes is a valuable amendment to agricultural soils and an efficient and economical way to seize carbon. Using biochar it is possible to increase the diversity of agricultural land in an environmentally sound way in areas with depleted soils, limited organic resources and insufficient water for development. Helps to soil carbon sequestration with negative CO2 balance, increases the productive potential of agricultural ecosystems.
