Yes you're speaking of the element, in agriculture it's about the compound. No element is delivered pure: potassium to an agricultural producer means potassium chloride, potassium sulfate, etc. For example: ammonium sulfate is far superior to urea as a form of nitrogen, and even then you're really talking nitrates or ammonia. The Biochar is superior because of the carbon - anything containing carbon is superior - however, due to the low bulk density and low nutrient density, it is hard for it to compete with concentrated fertilizers - such as murate of potash - because of the significant increase in shipping and handling, application, fuel, and labor costs associated with it.
