MIXED OR COMPLETE FERTILIZERS 
SOILTONE fertilizer is a combination of chemical 
ammonia nitrate and organic humus from sewage 
disposal containing twenty-four known minerals. 
While Soiltone shows only 6% available nitrogen 
it is assured that it will all be used by plant life 
because it is completely surrounded by organic 
humus which has an affinity for rainfall and 
moisture and prevents leaching by wind or water. 
Soiltone is the ideal combination of micro-organisms 
or bacteria which break down the organic ma- 
terial and minerals in the soil while drawing 
nitrogen from the air. Soiltone has humus of manure 
plus minerals which manure does not have. One 
ton of dehydrated Soiltone contains the humus 
value of many tons of barnyard manure.
