Joel focuses on various aspects related to sustainable farming practices in dry areas including vegetation growth with limited water resources, and increasing organic matter in soil for better moisture retention. He explains concepts like controlled grazing and pulsing, using forests for adding carbon material, capturing rainwater through ponds, and understanding grass as nature’s solar panels converting sunlight into edible biomass. Joel is passionate about mutual interdependence over independence when it comes to land ownership; recommended books/resources for learning about sustainable agriculture practices.
