abstract = {Intensive fertilization has been required to provide
nutrients for plant growth under the current agricultural
practices being applied to meet the global food demands.
Micronutrients such as zinc, manganese, and copper are
required in small quantities when compared to macronutrients
(such as nitrogen, phosphorus and potassium), but they are
essential for the plant growth cycle and consequently for
increasing productivity. Mineral oxides such as ZnO, MnO,
and CuO are used in agriculture as micronutrient sources,
but their low solubility limits practical applications in
plant nutrition. Similarly, elemental sulfur (S0) can
provide a high-concentration source of sulfate, but its
availability is limited by the ability of the soil to
promote S0 oxidation. We propose here the integration of
these nutrients in a composite based on a biodegradable
starch matrix containing mineral oxides and S0 in a
dispersion that allowed encapsulation of the acidifying
agent Aspergillus niger, a native soil fungus. This strategy
effectively improved the final nutrient solubility, with the
composite starch/S0/oxidemixture multi-nutrient fertilizer
showing remarkable results for solubilization of the oxides,
hence confirming a synergic effect of S0 oxidation and
microbial solubilization. This composite exhibited an
extended shelf life and soil–plant experiments with
Italian ryegrass (Lolium multiflorum Lam.) confirmed high
efficiencies for dry matter production, nutrient uptake, and
recovery. These findings can contribute to the development
of environmentally friendly fertilizers towards a more
sustainable agriculture and could open up new applications
for formulations containing poorly soluble oxide sources.},
