I'm sure its out there, but I cant find it. Is there some kind of equation to see how much of a product needed to add. Lets say I am low on copper. My soil test reads 0.2 ppm how much product on 1000 square feet will raise it to 0.3 or 1 or any other number. Or is it not that simple?

the equation I have is: 1ppm =2grams/100sq ft=20 grams/1000square ft. That's for pure mineral which is always in a salt form. So divide by ratio of weight. Ex manganese sulfate is 32% by weight manganese.So you would divide by .32 to figure out weight of mnsulfate to get the desired weight of Manganese

send me an email: [email protected] I've created a spreadsheet that takes your soil data, patch size, and recommends how much product to reach your desired goal.
