Biofortification of maize with micronutrients by Spirulina

摘要

The aim of the present work was to examine the effect of the application of Spirulina platensis post-extraction residues enriched with Zn(II), Mn(II), Cu(II) via biosorption as micronutrient fertilizer for the biofortification of maize grains with micronutrients in field tests. As a nominal dose 2.5 kg ha(-1) of zinc, 1.0 kg ha(-1) of manganese and 0.5 kg ha(-1) of copper were applied. The preparation was applied also in higher doses (150%, 200%) to investigate agronomic biofortification of maize grains.
