If the farmer continues to remove crops from the soil without replacing the phosphate 
removed in the crop, it is only a question of time before the phosphate will be exhausted. 
POTATOES 
What plant foods do potatoes require? 
CLOVER and ALFALFA SEED 
Clover and other Legumes need 
Phosphate. 
Clover and all other legume crops are usually 
very responsive to phosphate fertilization, espe¬ 
cially in western soils which are highly defi¬ 
cient in phosphate. 
The same methods as those employed in ap¬ 
plying phosphate to alfalfa can be used for all 
legume crops. 
To meet the annual needs of the crop, top- 
dress every other year with Anaconda Treble 
Superphosphate. 
A few of the many profitable results from 
the use of Anaconda Treble Superphosphate on 
alfalfa and red clover seed crops:

Potatoes, like all crops, require nitrogen, 
phosphate and potash, but the grade of fertil¬ 
izer to use depends entirely upon the condition 
of your soil. 
With rare exceptions there is a great suffi¬ 
ciency of potash in most western soils—a sup¬ 
ply much greater than the actual needs of the 
soil for years to come. 
The potato crop is a heavy feeder of phos¬ 
phate. An application of from 200 to 250 lbs. 
per acre of Anaconda Treble Superphosphate is 
recommended. 
Phosphate is the Master Key to a Permanent 
and Successful Agriculture 
The average increase in yield of potatoes, 
from the use of Anaconda Treble Superphos¬ 
phate, on a large number of tests was 34 100-lb. 
sacks per acre. Increases of 75 to 100 sacks per 
acre are not uncommon. 
Test No. 1. 684 lbs. 603 lbs. 
Test No. 2 . 760 lbs. 660 lbs. 
Use it for ALFALFA 
A plant of special soil requirements, 
among which are: 
1. Lime enough to prevent or neutralize excessive 
soil acidity and meet the very large needs of the 
plant with respect to the plant food element— 
calcium. 
2. A liberal supply of all the other mineral ele¬ 
ments of plant food. 
Alfalfa is one of the heaviest feeders on phosphate 
and surely the expression “Alfalfa is a hog for 
phosphate” is very true when we consider that it 
takes about 100 pounds of Anaconda Phosphate to 
replace phosphate lost in one season when four tons 
of alfalfa hay are harvested. 
Probably the most serious problem confronting 
the alfalfa grower of the West is the known fact 
that alfalfa does not hold its stand as formerly. 
Alfalfa has been known to stand for 20 to 25 years 
without reseeding while it is now difficult to keep 
the crop more than four or five years. Continual 
cropping, year after year, without replacing the 
plant food taken out is the direct cause of lower 
yields and shorter life of stands. 
Well-Fed Alfalfa Thrives 
Phosphate fertilizer gives marked increase in 
yield. The increases vary from 1 to 4 tons per acre, 
depending on climate, water and degree of phos¬ 
phate deficiency in the soil. 
Of almost equal importance with the increase in 
yield is the improved feeding value of phosphated 
alfalfa. Phosphated alfalfa contains a larger per¬ 
centage of leaf, often 2 5% more. This means a 
material increase in protein as well as the mineral 
content of the hay. Mineral deficiency in livestock 
can usually be corrected by feeding alfalfa that has 
been liberally fertilized with phosphate. Sufficient 
phosphate also helps nodule formation and result¬ 
ing in greater nitrogen fixation. There is also less 
winter killing when alfalfa is treated with phos¬ 
phate, due to greater strength.
