Incompatibles in fertilizer mixtures (U. S. Dept. Agric). 



The danger of indiscriminate mixing of fertilizing materials should 

 be understood, and a diagram (Fig. 4) is given to indicate what com- 

 binations may be safely made of some of the more common materials.

In this diagram the heavy lines unite materials which should never be 

 mixed, the double lines those which should be applied immediately 

 after mixing, and the single lines those which may be mixed at any time.
