Mixing fertilizers
Hey guys.
This is my first post. Yesterday I wrote a program that figures out the best way to combine seperate fertilizers to get a nutrient profile that better matches one you want. So, for example, if I wanted a fertilizer that was, say, 13-1-13 but I didn't have one, but I did have 3 other fertilizers, it would tell me how many grams of each I need to add to a litre of water to get my desired 13-1-13. Also works with just 2 other fertilizers. Anyway, I have an ideal nutrient profile I've put together from information I found online all day yesterday. And I want you guys to take a look and tell me if you think anything stands out as wrong. This will be a fertilizer for tomatoes: Nitrogen: 125 ppm Phosphorus: 9 ppm Potassium: 125 ppm Calcium: 140ppm Magnesium: 48 ppm Boron: 1.5 ppm Mo: 0.12 ppm Sulphur: ? (As an NPK rating: 12.5-0.9-12.5) Also, if the above profile is correct, then I can tell you that if you have Miracle Gro and Phostrogen, you can get a better profile with 0.3g of Miracle Gro and 0.38g of Phostrogen than with either alone. (Obviously you'd make more than one litre. I don't expect any of you to mix micrograms of ferts.) So, I'm probably completely wrong and I need someone here to point it out. Thanks. |
