Introducing U-Grow: The #1 Fertilizer!

Posted by Julia Cavicchi on July 8, 2025

Our urine fertilizer–permitted for land application in Vermont since 2012 by the Vermont’s Department of Environmental Conservation–is now registered as an official fertilizer! “U-Grow” is made from urine collected through Rich Earth’s community-scale urine nutrient reclamation program and processed using pasteurization technology developed by Rich Earth’s spin-off company, Brightwater Tools. U-Grow is certified in both Vermont and Massachusetts. We’re particularly excited about the precedent that this certification sets in MA, as the first legal authorization of land application of urine-derived fertilizers. This milestone is especially significant for coastal communities like Cape Cod, where urine diversion offers a practical tool for addressing an urgent wastewater crisis, and for Western Massachusetts, a hub of interest in sustainable farming. Local farmers and gardeners interested in accessing U-Grow should complete this form.
