      abstract     = {During biogas production anaerobic digestion of plant
                      material produces a nutrient-rich residue called digestate.
                      The application of the nutrients present in the digestate
                      should improve soil fertility, particularly in nutrient poor
                      soils, and thus crop yield, promoting the closure of the
                      nutrient cycle. This study evaluated the effect of digestate
                      application on the germination and early stages of plant
                      development since these are the first steps to be considered
                      when studying the benefits on plant growth in low fertility
                      substrates. A greenhouse experiment was conducted to
                      evaluate the effects of three substrates of different
                      texture and fertility (field loam, field sand, sand), as
                      well as type and amount of fertilizer (pure maize digestate
                      vs. inorganic nitrogen/phosphorus/potassium (NPK)
                      fertilizer) on both germination and early plant performance
                      of maize (Zea mays L. subsp. mays). While digestate and NPK
                      fertilizer applications had no significant effect on
                      germination in the two field soils, digestate applications
                      significantly decreased the germination rate in sand
                      $(36–82\%$ reduction) due to an increase of surface water
                      repellency. In contrast, for aboveground biomass yield, the
                      most positive fertilization effects of digestate application
                      were found on sand (up to 3.5 times the biomass of the
                      unamended control) followed by field sand (1.5 times),
                      compared to no effect for field loam. Our findings suggest
                      that digestate application have positive fertilization
                      effects in low-fertility substrates, similar to NPK, even
                      though digestate application may have a negative impact on
                      the permeability in sandy substrates that could interfere
                      with germination},
