About the Webinar

In this webinar, John will focus on helping farmers understand simplified root media and fertility management options for high quality transplants.  Topics covered include: 1) growing container options, 2) selecting and blending root media components and amendments, 3)  water soluble and mid-crop nutrient sources, 4) compost as a primary, on-farm or locally available root media and nutrient management tool, and 5) how irrigation methods impact root media and nutrient management.
