PPM Fertilizer Calculations

_Jack's Nutrients 12-4-16 RO

mg of fertilizer = target ppm (mg L) / % of desire element in compound

= mg of fertilizer in 1 liter of water to supply target ppm

50 ppm N .47 L of distilled water
50 ppm / .12 % N * .47 L
0.196 g of nutrient in .47 L
100 ppm N 1.7 L of distilled water
100 ppm / .12 % N * 1.7 L
1.417 g of nutrient in 1.7 L
125 ppm N 1.7 L of distilled water
125 ppm / .12 % N * 1.7 L
1.771 g of nutrient in 1.7 L

Task List

Dr. Alec Wehmeier
  • Secondary chemical storage in 372C?
    • I can store chemicals in any place others are storing chemicals.
  • Wasn't clear, can I use DI water?
    • Yes, I can use DI water from the labs.
  • For food safety, I can measure and mix the water in the lab correct?
    • Yes, I can measure and mix the fertilizer water inside the lab.
  • Transfer of materials between labs? Better to move the chemical or the pc/ec meter?
    • It's okay!

Frequently Asked Questions

What is this white, mineral build-up on my clay pebbles?

Accumulating on the surface of clay pebbles, white buildup primarily results from salt residues left behind as water evaporates.
