摘要

The transition from mineral to OMFs in agriculture is driven by the need to address climate change, resource limitations, and stable crop production. This study focuses on developing and testing organo-mineral micronutrient fertilizers for maize (Zea mays L.), using biomass as a carrier for micronutrients. Fertilizers containing zinc (1 kg/ha), manganese (0.4 kg/ha) and copper (0.2 kg/ha) were tested at 100, 150 and 200% doses for two years. Crop yield, quality, and multi-elemental composition (ICP-OES) were assessed and compared to traditional inorganic fertilizers to assess micronutrient bioavailability. Maize treated with OMFs showed a 10% increase in micronutrient content compared to commercial fertilizers. The best results were observed at 100% and 150% doses, with higher doses reducing micronutrient transfer. Biofortified maize grains, enriched with zinc, manganese, and copper, offer a potential solution to address micronutrient deficiencies in food and feed. The fertilizers are cost-effective and environmentally sustainable, providing an effective way to recycle biomass and improve crop nutrition. They contribute to addressing global micronutrient deficiencies and support more sustainable agricultural practices.
