What nutrients do biosolids contain?
Biosolids deliver a full suite of macro- and micronutrients, making it a superior source of plant food over synthetic fertilizers. Specifically they contain large amounts of nitrogen and phosphorus along with low amounts of potassium. Biosolids also have organic matter which provides food for soil microbes, builds soil tilth, and improves overall soil health. The micro-nutrients or significance are zinc, magnesium, manganese, copper, Iron, and molybdenum, which are just as important in maintaining healthy soil to meet your high yield goals.
