Using of digestate of agricultural biogas stations

This work deals with problems of agricultural biogas stations with the focus on using of final product of anaerobic fermentation, digestate, on agricultural soil. It evaluates its fertilizing effect in comparison to industrial fertilizers. The results showed that the fertilizing effect can improve economy of growing plants, however it depends on quality of digestate, constitution of base input material and technology of processing. It is not possible to use digestate anytime, it depends on growing crops and its technology. Nevertheless digestate as a final product of anaerobic fermentation is an interesting fertilizer
