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. 
Use it for ALFALFA 
A plant of special soil requirements , 
among tvhich 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. 
GRAINS 
Fertilizers Make Better Grains 
There are many different ways in which phos¬ 
phate helps out the small grain crops and some of 
these are: 
1. It aids the young plant in stooling out, thus 
making extra stems, which increases the yield. “Ev¬ 
ery added stolon means an extra head of grain.” 
2. Applied to late sown grains, it enables the 
plant to “make up for lost time” an especially im¬ 
portant point in territories of short growing seasons. 
3. By producing a good winter covering, it pro¬ 
tects the soil from alternate freezing and thawing 
and thus makes the winter wheat less subject to 
winter injury. 
4. By producing a strong root growth, injury 
from heaving is decreased and an earlier and 
stronger growth results in the spring. 
5. It hastens the maturity and pushes the crop 
ahead of rust injury and drouth damage. 
6. It stiffens the straw and prevents lodging. 
7. It produces quality grain. 
8. It helps succeeding crops that follow grain. 
Grains respond to fertilizer so well that this crop is 
now generally fertilized by middle-west farmers. On 
the newer soils of the western states, too, fertilizers 
(phosphate) are giving profitable returns. 
Increases in yield of wheat of from 7 to 3 0 bush¬ 
els per acre from the use of Anaconda Treble Super¬ 
phosphate are quite common. The average increase 
in yield in the Twin Falls, Idaho, districts from a 
large number of tests was 2 7 bushels per acre. 
Where tried and proven, the use of phosphate is 
now recognized by all as a sound and profitable 
farm practice. The only remaining question for the 
farmer who has not formerly used phosphate is 
“Will it pay on my farm?” A trial will tell. 
POTATOES 
W hat Plant Foods Do Potatoes Require? 
Potatoes, like all crops, require nitrogen, phos¬ 
phate and potash, but the grade of fertilizer to use 
depends entirely upon the condition of your soil. 
With rare exceptions there is a great sufficiency 
of potash in most western soils—a supply much 
greater than the actual needs of the soil for years 
to come. 
The potato crop is a heavy feeder of phosphate. 
An application of from 20 0 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 Superphosphate, on a 
large number, of tests was 3 4 100-lb. sacks per acre. 
Increases of 75 to 100 sacks per acre are not un¬ 
common. 
CLOVER AND ALFALFA SEED 
Clover and Other Legumes Need Phosphate 
Clover and all other legume crops are usually 
very responsive to phosphate fertilization, especially 
in western soils which are highly deficient in phos¬ 
phate. 
The same methods as those employed in applying 
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 Superphos¬ 
phate.
