I've been thinking, (I know, that could cause trouble). A person may be able to use Nitrogen in a liquid form; but that means carrying it in some carrier like a tank from the supplier to your plot. But then, if I understand this, you have to transport the P and K in ganular form and spreading this dry. This would create a lot of extra steps to get fertilizer on a plot or plots. A farmer working with large fields may be able to operate this way OK, but for plots would create a lot of extra work. An I thinking straight?
