First Choice Among 
Experienced Gardeners 
for BEST RESULTS 
COMPARATIVE tests reveal two or three times the root growth in plants 
fertilized with Tol-e-Gro, as compared with plants otherwise fertilized and 
grown under identical conditions. Hills of potatoes on good loam soil, fertilized 
with Tol-e-Gro showed 200% increase in yield over hills next to them, on which 
Tol-e-Gro was not used. Lawns fertilized with Tol-e-Gro showed steady consist- 
ent improvement. Shrubs, trees and flowers reveal similar favorable results. 
Here Is The Reason! 
In Tol-e-Gro you obtain the ideal combina- 
tion of micro-organisms or bacteria which 
break down the organic material and min- 
erals in the soil, while drawing the essential 
nitrogen from the air, thus making them 
available continuously to plant life, as 
needed. Tol-e-Gro serves “regular meals” 
of plant food as contrasted with the over- 
doses and temporary benefits of many 
chemical or inorganic fertilizers. 
The micro-organisms in Tol-e-Gro are harm- 
less to human beings, but extremely bene- 
ficial to plant life because they are carriers 
of nitrogen taken from the air, transform- 
ing it into ammonia, then into nitrites, and 
finally into nitrates which are supplied in 
abundance AS THE PLANTS NEED THEM. 
Tol-e-Gro holds many times its volume and 
weight in moisture, thus keeping the dis- 
solved nutrients in contact with the roots 
much longer than with nitrate salts of in- 
organic chemical fertilizers, which are 
easily leached out by rains and partially 
wasted. 
Superior, Yet Inexpensive 
Although Tol-e-Gro is comparatively inex- 
pensive, it offers an unusual supply of 
many elements essential to plant growth 
other than Nitrogen, Phosphorus and Potas- 
sium, the basic elements found in all 
fertilizers. 
For instance, manganese is a constituent of 
nearly all field and garden crops, and is 
now considered essential to normal growth. 
Reference to the table elsewhere in this 
folder shows an average of 12 pounds of 
manganese in each ton of Tol-e-Gro. 
Arsenic, when present in small quantities 
stimulates the growth of plant life. Sandy 
soils are often deficient in aluminum, and 
calcium is especially essential to non-legume 
crops. These and many other minerals of 
known value contribute to the balanced 
efficiency of ‘Tol-e-Gro. 
In fact its only equal is well-rotted barnyard 
manure, which is often unobtainable, and 
much more disagreeable to handle, especi- 
ally on city lawns, shrubs and small gardens. 
Tol-e-Gro, like barnyard manure, supplies 
plant food in normal proportions, and con- 
tinuously returns to the soil all elements 
which plant life is taking from it.
