What Good Shall I Do Conference | Compost Workshop

Starting a composting practice can feel intimidating, this workshop is meant to breakdown the barriers that may be preventing you from gaining momentum. Composting does not have to be complicated, and when done in a way that fits into the context of your life, it’s a rewarding practice that can bring us closer to our food and land!


This workshop is for registered attendees of the What Good Shall I Do Conference

Force of Nature's annual "WHAT GOOD SHALL I DO" conference brings together ranchers, farmers, researchers, nutritionists, and conscious consumers for 2-3 days of education, networking, planning, and ACTION focused on regenerating ourselves and our landscapes. You don't want to miss this outdoor experience on the Pedernales River at ROAM Ranch!

Regenerative Grazing for Soil Health: Managing the Livestock Above & Below Ground

During this two-day workshop, we will concentrate on how we can manage the livestock above ground to help manage the livestock below ground, and create healthier pastures, livestock, and soil. This typically leads to reduced inputs and increased profits, together with increased carrying capacity leading to more production!

December 10, 2023 | Next Level Composting: How to Create a Johnson-Su Bioreactor

Learn how to make an excellent soil amendment in your own backyard by joining us in this hands-on workshop where we will learn about Johnson-Su Bioreactors together! A Johnson-Su Bioreactor is a low-maintenance, passive composting system that yields highly fungal compost!


This design was created by husband-wife duo, Dr. David Johnson and Hui Chun Su, during Johnson's PhD research at New Mexico State University. The method has since been modified to become very easy for backyard compost making.

 In this workshop we’ll observe a bioreactor created for Circle Acres Nature Preserve and discuss why and how the bioreactor works, as well as how to successfully build, maintain, and use the compost in a yard or garden.

Led by Andie Marsh, Rhizos LLC, and Eric Paulus, Ecology Action of Texas.
