Feeding the world sustainably
The cHALLENGE
Fertilizer hasn’t changed in over a century—it’s costly, limits productivity, pollutes, and poses a growing national security risk. Without it, we don’t have enough food. It’s critical, not optional.
A CRITICAL NEED
Fertilizer is the bedrock of crop production, supporting food security worldwide.
national security
Supply chain disruptions and geopolitical tensions are driving price volatility for fertilizer-importing countries, threatening food security and highlighting the need for localized solutions.
Affordability
Fertilizer is expensive, accounting for about ⅓ of farmers’ crop input costs. Rising prices make affordable and reliable food production impossible.
Energy Demand
Fertilizer production is highly energy-intensive—nitrogen fertilizer alone uses as much energy each year as all U.S. homes combined.
Stewardship
Almost 50% of applied nitrogen fertilizer runs off fields—polluting water, degrading soil, and harming natural resources around the world.
The solution
We engineer naturally occurring microbes that produce fertilizer directly on plant roots—reducing costs, runoff, and supply chain risks by making fertilizer on the farm, where it's needed.
produce
We produce microbes and formulate them into a powder. Each ounce of powder contains billions of sleeping microbes.
Apply
Farmers rehydrate microbes to awaken them and apply at crop sowing.
Grow
Microbes first proliferate alongside germinating plants. More microbes, more nitrogen!
feed
Through a proprietary mechanism, microbes then switch on nitrogen fertilizer production.
Led by Tim Schnabel, the Switch Bioworks team is made up of almost exclusively scientists and bioengineers, all focused on the engineering grand challenge of creating a sustainable fertilizer.
