Research Evaluates Diversity in Chemical Composition of Biofertilizers

Researchers from University of Brasilia assessed the chemical characteristics of agro-industrial residues used in the manufacture of an aerobic liquid biofertilizer

Increasing adoption of sustainable agricultural systems has propelled the use of biofertilizers. Biofertilizers can increase crop productivity According to ‘Biofertilizers Market Size, Share & Trends Analysis Report By Product (Nitrogen Fixing, Phosphate Solubilizing), By Application (Seed Treatment, Soil Treatment), And Segment Forecasts, 2012 – 2022’ published by Grand View Research Inc., in 2016, the biofertilizers market was value at US$ 787 million. According to ‘Improving Crop Yield and Nutrient Use Efficiency via Biofertilization—A Global Meta-analysis’ study published in Frontiers in Plant Science in 2018, although biofertilizers may differ considerably in response to the formulation used, the productivity of cereals, vegetables, legumes, and root crops may increase by 20%.

Now, a team of researchers from University of Brasilia and Brazilian Agricultural Research Corporation chemically distinguished agro-industrial residues used in the production of an aerobic biofertilizer. The team also assessed the agronomic potential of the residues. According to the researchers, the Brazil agriculture sector accounts for around 30% of the GDP. However, the country also imports almost all NPK fertilizer. This in turn restrains the growth of sustainable production systems in which the number of fertilizer options are limited. Therefore, the team stressed the need for development of other sustainable alternatives.

Recycled agro-industrial byproducts can lead to development of biofertilizers as alternatives and can aid in decreasing the dependency on fertilizers. The chemical composition of biofertilizers is uncertain. This can be attributed to extensive differences in the sources and nutrient contents of the raw materials. Moreover, the presence of heavy metals in biofertilizers is an environmental concern. The team found that no standard measures are available that monitor the nutrient content of different biofertilizers. The team compared the raw materials of its fertilizer with others counterparts and classified into two key sets: One set accounts for manure from different animals, whereas the other considers agro-industrial or household wastewater. agro-industrial or household wastewater-based biofertilizers demonstrated higher amounts of NPK and calcium compared to manure-based counterpart. The research was published in the journal MDPI Sustainability on April 3, 2019.
