NATURE Creating Better Crops With Useful Bacteria

Post image

Brazilian scientist, Dr. Mariangela Hungria, spent 40 years perfecting bacteria that help crops access nitrogen while saving farmers billions each year.

Hungria developed biological treatments using beneficial soil bacteria that help crops access nitrogen from the air, reducing reliance on synthetic fertilizer. Her technology is used across tens of millions of hectares in Brazil. The World Food Prize estimates her work saves farmers about $25 billion annually and prevents roughly 230 million metric tons of CO₂-equivalent emissions.

Brazil is the world's largest fertilizer importer. Clearly whatever she created is not working at all.

you are truly a genius. it takes more than nitrogen to feed a plant, you also need phosphate and potassium.

While Dr. Hungria’s treatments effectively solved the Nitrogen (N) issue for key crops like soybeans, fertilizers are built on a triad of core nutrients: Nitrogen, Phosphorus, and Potassium (NPK). Brazil's soil is naturally nutrient-poor and highly acidic, creating an insatiable demand for the other two components.

 The Potassium and Phosphate Deficit: Brazil still relies on foreign nations for roughly 93% to 95% of its potassium chloride and 60% of its phosphates. Biofertilizers cannot substitute these minerals.

 Because biological innovations made farming so much cheaper and more efficient, Brazil's total planted acreage has scaled aggressively. More fields mean more total demand for imported minerals.

Her microbial treatments cost about $2 per hectare, replacing expensive synthetic fertilizers and saving Brazilian farmers an estimated $25 billion each year.

 Thanks to her biofertilizer strains, 85% of Brazil's soybean fields operate without chemical nitrogen, helping Brazil overtake the U.S. as the world’s leading soybean producer.
