Sucking up CO2
HQ: Somerville, MA
Low-runoff biofertilizer as cheap and effective as synthetic.
Synthetic fertilizers enabled massive strides in agricultural productivity. Yet, production and over-application of these chemicals also account for 7% of global GHG emissions, largely in the form of N2O, which has 265x the warming potential of CO2. The challenge for alternatives is to achieve cost-competitiveness while preserving the versatility of synthetic fertilizers in adapting to a range of soils and species.
How it Works
Kula Bio engineers microbes that fix nitrogen directly from the air. A barrier for other enzyme-based fertilizers is identifying energy sources to keep microbes alive long enough to fix significant quantities of nitrogen. Kula supercharges microbes so that they store energy within their cells giving their microbes a weeks-long energy source, allowing them to replace up to 100% of synthetic nitrogen.
The result is an non-GMO biofertilizer that can fully replace synthetic nitrogen fertilizer across a broad range of crops, soils, and climates. Relative to synthetics, Kula will be both cost-competitive and more efficient at scale. Relative to organic fertilizers, the case for switching is even stronger. It will cost a fraction to produce and can be applied on-demand, rather than 9-12 months ahead.
