Prototype for the harvesting of cultivated herbaceous energy crops, an economic and technical evaluation

Considering the hectares that can be covered by the biotriturator (170 ha of sorghum and 270 of switchgrass, with an average annual use of 200 h) and the total harvest cost (9.9-12.1 € Mg−1 dry biomass), the harvesting system represents an effective solution for situations like that in Italy, where average farm sizes are small.
