Step 5: Additional Questions
The greenhouse manager was asked the following questions:
- What are you fertilizing with?
Answer – We fertilize with our brand name water-soluble fertilizer. It is rated 20-20-20, and has added micronutrients.
- How much iron is in the fertilizer?
- How do you apply the fertilizer?
Answer: With a fertigator. We put about one cup of fertilizer into a 5-gallon bucket and fill it with water. Then the machine dilutes it into the irrigation water.
- Do you know by how much it dilutes the concentrate to?
Answer: Not sure, but it might say on the machine. (it was all faded and unreadable)
