      abstract     = {Agricultural output needs significant increases to feed the
                      growing population. Fertilizers are essential for plant
                      production systems, with nitrogen (N) being the most
                      limiting nutrient for plant growth. It is commonly supplied
                      to crops as urea. Still, due to volatilization, up to 50
                      $\%$ of the total N application is lost. Slow or controlled
                      release fertilizers are being developed to reduce these
                      losses. The co-application of zinc (Zn) as a micronutrient
                      can increase N absorption. Thus, we hypothesize that the
                      controlled delivery of both nutrients (N and Zn) in an
                      integrated system can improve uptake efficiency. Here we
                      demonstrate an optimized fertilizer nanocomposite based on
                      urea:urea-formaldehyde matrix loaded with ZnSO4 or ZnO. This
                      nanocomposite effectively stimulates maize development, with
                      consequent adequate N uptake, in an extreme condition – a
                      very nutrient-poor sand substrate. Our results indicate that
                      the Zn co-application is beneficial for plant development.
                      However, there were advantages for ZnO due to its high Zn
                      content. We discuss that the dispersion favors the Zn
                      delivery as the nanoparticulated oxide in the matrix.
                      Concerning maize development, we found that root morphology
                      is altered in the presence of the fertilizer nanocomposite.
                      Increased root length and surface area may improve soil
                      nutrient uptake, potentially accompanied by increased root
                      exudation of essential compounds for N release from the
                      composite structure.},
