Rolla, ND | A unit of fertilizer is the amount necessary to give one lb. of the desired nutrient.
100 lbs of potash gives you 60 units of K2O. It is all potash (potassium chloride) except for a few impurities.
People kind of mess up the whole potash-potassium-potassium oxide equivalent thing.
If you take potash and take the equivalent K2O number and the amount of Cl in it you actually end up with over 100% plant food. It is 60% (actually more like 62%) K2O and 45% chloride. The thing is, it actually contains no K2O we are talking equivalents.
Whenever talking fertilizer and the word actual comes up there always seems to be conflict because everyone seems to use it differently. | |
