These being the chief objects of the investigation, it will be neces- 

 sary to speak but briefly of the manured and fertilized plots. 



The manured plot received the first year two tons and in all subse- 

 quent years one and one-half tons of mixed horse, cow and sheep 

 manure, which had been kept in a covered yard during the winter and 

 until the last of May, when it was removed to a rotting pit in the open 

 field, from whence it was taken in September to the plots and spread on 

 the surface of the plowed ground. The manure contained a high per 

 cent of nitrogen owing to the liberal use of cotton-seed meal in feed- 

 ing the animals. After the first year the wheat had a tendency to 

 lodge, which tendency became so bad in the last year of the experi- 

 ments that in the fall of 1892 no manure was used. On plot 3, 60 lbs. 

 of Bradley's superphosphate were drilled in with the seed in the first 

 three years, in the fourth, 60 lbs. of Small's superphosphate, and in the 

 fifth, 15 lbs. of double superphosphate, 15 lbs. of sulphate of potash 

 and 10 lbs. of sodium nitrate. Briefly stated, it may be said that the 

 plot received annually 45 lbs. of phosphoric acid, 15 lbs. of potash, 

 and 15 lbs. of nitrogen per acre. 



Plot 4, which was in wheat without any " rest " by means of a sum- 

 mer fallow was plowed, as were all the plots immediately after harvests, 

 harrowed, rolled and cultivated several times, making indeed a short 

 summer fallow. 



All plots contained one-tenth of an acre each. Two plots were used 

 in the TuU or summer fallow system, so a crop was harvested on each 

 every other year, while in all other cases a crop was harvested every 

 year.
