some of the strips. The following outline will 

 show how to make such an experiment on about 

 half an acre : 



Plat 1.— Nothing* 



2. — ^200 pounds nitrate of soda per acre in 



two or three applications. 

 3. — 600 pounds acid phosphate. 

 4. — Nothing. 



5. — 100 pounds muriate of potash. 

 6. — 100 pounds muriate of potash and 200 

 pounds nitrate of soda in two or three 

 198 feet. ; applications. 



7.— Nothing.* 

 8. — 100 pounds muriate of potash and 600 



pounds acid phosphate. 

 9. — 100 pounds muriate of potash. 

 600 pounds acid phosphate. 

 200 pounds nitrate of soda. 

 10.— Nothing. 



144 feet. 



One hundred pounds per acre is one pound 

 for 48 square yards, a strip, say, one yard 

 wide and 48 yards long. 



It may be necessary to repeat the experiment 

 several years, before we can be sure what will 

 give the best results; but we shall learn much 

 that wUl help even during the first year. 



* Note. — If the yields of plats 1 and 7 do not agree closely, the 

 effect of the fertilizer can be closely estimated by comparing the 

 yield of each with the check plat nearest to it. Another interesting 

 experiment is to lime one-half of each plat.
