Ground Rock Phos 



That Pays 



THESE are times when every farmer must 

 lower his cost of production. The yield per 

 acre is the most important factor in per bushel or 

 per ton costs. The quality of the grain, whether 

 or not it matures before frost, may make the 

 difference between profit and loss. Perhaps phos- 

 phorus is all your soil needs to greatly increase 

 its yielding capacity. 



No investment pays such a large return as 

 ground rock phosphate (also called lime phos- 

 phate) correctly applied on soil which needs it. 

 Even at current low prices rock phosphate has 

 paid a return of more than 300 per cent in one 

 crop rotation period. 



Increased Yield 20-30 Bu. 



HH. BISSELL, Iroquois county, Illinois, 

 . says: "Rock phosphate has increased our 

 crops 20 to 30 bushels per acre." 



Sam Stadler, Ford county, Illinois, says: "Have

used about 150 tons of your phosphate with good 

 results. Matures corn 10 days earlier than where 

 we did not use it. It makes two stalks of clover 

 grow where one grew before." 



Shuman Farms, Moultrie county, Illinois, re- 

 ports: "The corn on the phosphated land yielded 

 46.1 bushels per acre, while that in the same field, 

 but without phosphate, yielded only 34.9 bushels 

 per acre. These results were better than we antici- 

 pated considering the dry season." 



More For Your Money 



NO PHOSPHATIC fertilizer gives so much 

 usable phosphorus per dollar of cost as 

 ground rock phosphate. Organized buying power 

 enables Farm Bureau members in Illinois to buy 

 ground rock phosphate at less cost than others. 

 The I. A. A. analyses on each carload guarantees 

 reliable quality and equitable price.
