Agriculture from the Ground Up
Agriculture from the Ground Up is a practical podcast that helps farmers, advisors, students, agronomists and anyone in agriculture build on to the knowledge they already have; from soils and nutrition to cropping, livestock, economics and decision-making, so that you can fuse it all together into even better, more confident and more profitable farming.
As an agriculture educator and perennial student, I want to help you fill those hidden gaps so you can make better decisions and grow a more resilient, profitable business.
