      abstract     = {Algae are capable of accumulating nutrients from aqueous
                      waste, which makes them a potential fertilizer. The ability
                      of the fast growing Chlorella vulgaris strain IPPAS C1 to
                      accumulate phosphorus (P) was probed in V-shaped plastic
                      foil photobioreactors. The P uptake was 0.13–0.53
                      g(P)·m−2·day−1 when the algal culture densities were
                      kept between 0.1 and 1.0 g(DW)·L−1 in a typical summer
                      irradiance of Central Europe. The algal biomass can be
                      effectively utilized for soil fertilization only if the
                      algal cells release nutrients into the soil in a form that
                      would be available to roots and at a rate sufficient to
                      support plant growth. To examine this, we compared the
                      growth of wheat, Triticum aestivum L., in two
                      nutrient-deficient substrates: “Null Erde” and sand,
                      with and without fertilization by wet and spray-dried algae.
                      Plants grown in the two nutrient-deficient substrates
                      supplemented by mineral fertilizer served as a control
                      representing optimal nutrient supply. Plants grown in a
                      high-nutrient substrate (SoMi 513) were used as an
                      additional reference representing the maximum growth
                      potential of wheat. Wheat growth was monitored for 8 weeks
                      and measured, including the increase of the leaf area as
                      well as shoot and root dry weight in 10 randomized
                      replicates for each substrate and fertilization variant.
                      After harvest, the biomass and N, P, and C contents of the
                      plant shoots and roots were recorded. Algae fertilization of
                      “Null Erde” led to wheat growth, including root hair
                      production, which was similar to mineral-fertilized “Null
                      Erde” and only slightly less vigorous than in the
                      nutrient-rich SoMi 513 substrate. The plants grown in sand
                      were smaller than the plants in “Null Erde” but
                      fertilization by algae nevertheless led to growth that was
                      comparable to mineral fertilizer. These results
                      unambiguously demonstrate that algal biomass is a viable
                      option for delivering nutrients to support agriculture on
                      marginal soils.},
