Characterization of Biochar Obtained from Olive and Hazelnut Prunings and Comparison with the Standards of European Biochar Certificate (E.B.C.)

Concerns about climate change and food productivity have spurred interest in biochar, a form of charred organic material, typically applied in agriculture to improve soil productivity and as mean of carbon sequestration. An innovative approach in agriculture is the use of agro-industrial waste for the production of soil fertilizers for agricultural purposes and as a source of energy. A common agricultural practice is to burn crop residues in the field to produce ashes that can be used as soil fertilizers. This approach is able to supply plants with certain nutrients such as Ca, Na, K, Mg, B, S and Mo. However the lack of N and P in the ashes, together with the occasional presence of heavy metals (Ni, Pb, Cd, Se, Al, etc.), has a negative effect on soil and therefore crop productivity. This work describes the opportunity to create an innovative supply chain from agricultural waste biomass. Olive (Olea europaea L.) and hazelnut (Corylus avellana L.) pruning residues represent a major component of biomass waste in the area of Viterbo (Italy). In this study, we evaluated the production of biochar from these residues. Furthermore, a physico-chemical characterization of the produced biochar was performed to assess the quality of the two biochars according to the standards of the European Biochar Certificate (EBC). The results of this study indicate the cost-effective production of high- quality biochars from olive and hazelnuts biomass residues.

Comparison between different protective devices for agricultural wheeled narrow track tractors and a risk index in orchard work

Contemporary Engineering Sciences (2015)

Danilo Monarca Massimo Cecchini Simone Di Giacinto Roberto Bedini Alessio Ghignoli

Since occupational accidents often occur in farm tractor drivers, it is extremely important to focus the attention on specific devices in order to avoid risks from tractor overturning. This phenomenon is actually considered as the leading cause of deaths or injuries related to agricultural work. The system adopted to reduce the above-mentioned risk consists of passive protection devices aimed at preventing the hazardous event which may affect workers’ health. More precisely, the tractor chassis (i.e. ROPS) and the proper seat belt define a “safety volume” around the worker. The aim of the present research is to carry out tests on narrow-track wheeled tractors with fixed roll over protective structures in those areas – such as hazel and olive groves and vineyards - where problems related to under–tree activities occur. This is to implement planting layout and/or cultivation techniques which can be considered suitable for tractors with roll over protective structures. According to that, their project parameters – i.e. safety volume, seat position and typology, test methods - can be successfully modified and improved. The results show that nowadays only a few agricultural vehicles are provided with specific fixed devices able to work under tree without damaging orchards.
