This workshop will focus on fertilizers and their use in nursery operations.  The first half of this program will describe fertilizer types such as granular fertilizers, Controlled Release Fertilizers (CRFs) and liquid fertilizers.  We will describe the pros and cons of each fertilizer type and how to optimize fertilizer performance.  The second half of the program will be dedicated to monitoring and measuring the quality of irrigation water and media.  We will identify and demonstrate methods of conducting on-site tests for measuring media quality and water quality.  We will then review protocols for proper sampling for off-site sample analyses.

Workshop “Key” Learnings:

  • Have a working knowledge of fertilizer types.
  • Choose the proper fertilizer(s) to optimize plant growth and have a sustainable operation
  • Use fertilizers properly to optimize nutrient uptake into plants
  • Monitor media and water quality
  • Develop a record keeping program to track production with fertilizer usage.
