      abstract     = {Cassava is a root storage crop that is important to the
                      starch industry and food security. In this study, the
                      sustainable fertilization of cassava using local placement
                      of struvite, a fertilizer recovered from wastewater, rich in
                      nitrogen, phosphorus, and magnesium, was investigated. It
                      was asked if struvite is a suitable fertilizer for cassava,
                      if it is likely to spread through the substrate (leach), and
                      if roots can proliferate and utilize a concentrated
                      placement of struvite. Cassava was grown in rhizoboxes under
                      different fertilizer placement strategies: unfertilized
                      control, homogeneous fertilizer distribution in the top 20
                      cm (‘homogenized’), a strip placement (‘layer’) at
                      20 cm depth, and a localized ‘depot’ at the same depth.
                      Shoot and root growth responses were monitored over 8 weeks.
                      Cassava growth was significantly improved with struvite
                      fertilization. The fertilizer remained localized, with
                      minimcnal spread during the 8 weeks of experimentation. Both
                      the ‘layer’ and ‘homogenized’ struvite placements
                      resulted in comparable biomass production, significantly
                      greater than the unfertilized treatment. Plants in the
                      ‘depot’ placement initially grew similar to the
                      unfertilized treatment as roots took time to locate and
                      proliferate into the fertilizer depot. Afterward, plants in
                      the ‘depot’ treatment grew quickly, resulting in an
                      intermediate biomass at harvest. Notably, cassava exhibited
                      strong root proliferation in response to concentrated
                      struvite, which did not compromise deep rooting but instead
                      appeared to enhance it, increasing specific root length.
                      These findings suggest that strip fertilization with
                      struvite may offer a sustainable fertilization strategy for
                      cassava, warranting further investigation in field trials.},
