Ppm dry ammendments

Hi, Unfortunately with the soil, you would need a soil test to get a true number for the ppm of the soil because there will be nutrients originally in the soil and then those you add on also. There are some at home soil tests but I'm not sure how well they work, there is one called the soil savvy test but you mail them a sample and then they send you the results and recommendations for what to add. This is most helpful if you're building a living soil. I don't believe Dry amendments have a ppm until they're being broken down in the soil, so I think the best way to gauge it would be through the runoff water. Checking, rechecking , and adding small increments. Or follow a specific recipe and then check several days after adding. I hope that helps some...good luck.👍

check dat even.. bookmark een periodiek systeem voor molaire massa eenheid of hoe het ook heet. (bijv. O is 15.9994 of 15.994? enz.) en ga daarvandaan... Maak een spreadsheet zodat je eenvoudig de grammen van componenten kunt veranderen en de resulterende ppm's onmiddellijk worden herberekend.
