Michigan - Saginaw County | uuuuh, because it IS 0-0-60 (not 50)
University research trials are done in pounds of K2O applied (and that is calculated by using the 0-0-% concentration the supplier says in the product sheet times the number of total pounds of product applied) They do not then convert the K2O weight to the weight to the element.
You can't get elemental K to put down because it will oxidize (burn) the instant it hits the air/soil and becomes K20 before your very eyes.
Metallic potassium is kept in a jug of kerosene in the lab to keep moisture and 02 away from it.
Don't get hung up on minutiae. 6-18-6 has 6 pounds of available K2O per hundred pounds, etc. |
