Water, nutrients, and substrates are core components of the root zone, and their management is critical to root health and overall plant performance. In “Water, Nutrients, and Substrates,” a four-part series, Root Alliance will present its latest research findings on water treatment design, ozone and cold plasma systems, recirculating hydroponic solutions, and stratified substrates.
Designed for: Industry professionals and researchers working in food, medicinal, and ornamental crop production who want to improve root health, reduce crop losses, and increase productivity. The program is designed for an intermediate experience level.
Learn about:
- Assessing risks associated with low-quality water
- Designing water treatment systems
- Customizing hydroponic solutions to prevent nutrient drift
- Water sanitation with cold plasma and ozone
- Selecting stratified substrates for water and cost savings
