ABSTRACT:
A method of fertilizing soil comprising the steps of treating soapstock with an acid containing phosphorus compounds, separating the acid oil from the acid water, and using the resulting acid water as fertilizer, or fertilizer component. Such use is particularly effective in precision fertilizer delivery systems having small passages which would be adversely affected by insolubles.
