Agriculture is responsible for about one quarter of all greenhouse gas emissions. So, to stop the planet from getting substantially warmer, we need breakthroughs in many sectors of our economy, including how we grow food.
Pivot Bio has a clean alternative to chemical fertilizer that could help transform farming and reduce climate change. It takes four things to grow a plant: sun, water, carbon dioxide, and nitrogen.
A plant is really good at getting the first three of those. But it can't make its own nitrogen.
Fertilizer is primarily nitrogen. And it's really what fuels and makes our food system possible.
It's because nitrogen is ultimately a building block of life. Fertilizer's done all these great things, but it also has a lot of negative side effects.
Making fertilizer creates a lot of pollution and using fertilizer creates a lot of pollution as well. One of those forms of pollution is nitrous oxide, a gas that's 300 times more potent as a greenhouse gas than carbon dioxide.
If we stopped using fertilizer tomorrow, we wouldn't be able to produce half of the world's food supply. But there's a possible replacement and it lies in the soil beneath our feet.
Microbes in the soil can also produce nitrogen for the crop. Before we had fertilizer, microbes played that role.
So, when we started breeding plants so that every harvest would produce more yield, we needed more nitrogen than the microbe in the soil could provide. And so, we invented fertilizer and we've caused those microbes in the soil to go into hibernation.
We founded Pivot Bio with one mission in mind: how do we reinvent what it means to provide nitrogen to our crops? So, if you pull a seedling out of the ground, attached to the roots are thousands and thousands of microbes.
