abstract = {Intensive agriculture and horticulture heavily rely on the
input of fertilizers to sustain food (and feed) production.
However, high carbon footprint and pollution are associated
with the mining processes of P and K, and the artificial
nitrogen fixation for the production of synthetic
fertilizers. Organic fertilizers or recovered nutrients from
different waste sources can be used to reduce the
environmental impact of fertilizers. We tested two recovered
nutrients with slow-release patterns as promising
alternatives for synthetic fertilizers: struvite and a
commercially available organic fertilizer. Using these
fertilizers as a nitrogen source, we conducted a rhizotron
experiment to test their effect on plant performance and
nutrient recovery in lupine plants. Plant performance was
not affected by the fertilizer applied; however, N recovery
was higher from the organic fertilizer than from struvite.
As root architecture is fundamental for plant productivity,
variations in root structure and length as a result of soil
nutrient availability driven by plant–bacteria
interactions were compared showing also no differences
between fertilizers. However, fertilized plants were
considerably different in the root length and morphology
compared with the no fertilized plants. Since the microbial
community influences plant nitrogen availability, we
characterized the root-associated microbial community
structure and functionality. Analyses revealed that the
fertilizer applied had a significant impact on the
associations and functionality of the bacteria inhabiting
the growing medium used. The type of fertilizer
significantly influenced the interindividual dissimilarities
in the most abundant genera between treatments. This means
that different plant species have a distinct effect on
modulating the associated microbial community, but in the
case of lupine, the fertilizer had a bigger effect than the
plant itself. These novel insights on interactions between
recovered fertilizers, plant, and associated microbes can
contribute to developing sustainable crop production
systems.},
