Closing the nutrient cycle by using bio-digestion waste derivatives as synthetic fertilizer substitutes: A field experiment

► We study the reuse of bio-digestion waste as synthetic fertilizer substitutes. ► Through a field-trial we evaluate their impact on soil and crop production. ► Application of these products slightly increased the soil quality and crop yield. ► The use of bio-digestion waste stimulated the soil nutrient use efficiency. ► Synthetic fertilizer substitution results in important economic & ecological benefits.
