Fertilizers applied each year from 1888 to 

 1898 or 1899. No fertilizers used from 

 that time to 1905. Clover sown in 1899 

 and each year since with the grain and 

 ploughed under in the autumn. In 1905 

 fertilizers again applied as at first, clover 

 discontinued. 



acre 



Barn-yard manure (mixed horse and cow 

 manure) well rotted 12 tons per acre in 

 1888 ; 15 tons per acre each year after to 



1898 inclusive. No manure used from 



1899 to 1905. In 1905 15 tons per 

 again used 



Barn-yard manare (mixed horse and cow 

 manure) fresh, 12 tons per acre in 1888 

 15 tons per acre each year after to 1898 

 inclusive. No manure used from 1899 to 

 1905. In 1905 15 tons per acre again used. 



Unmanured from the beginning 



Mineral phosphate, untreated, finely ground, 

 500 lbs. per acre, used each year from 1888 

 to 1897 inclusive. In 1898 and 1899 a 

 similar weight of the Thomas' phosphate 

 was used. No fertilizer used from 1900 

 to 1905. In 1905 Thomas' phosphate again 

 usad as in 1899 



Mineral phosphate, untreated, finely ground, 

 500 lbs., nitrate of soda, 200 lbs., per acre 

 used each year from 1888 to 1897 inclusive. 

 In 1898 and 1899, 500 lbs. of the Thomas' 

 phosphate was used in place of the mineral 

 phosphate. No fertilizers used from 1900 

 to 1905. In 1905 fertilizers again used as 

 in 1899 



Barn-yard manure, partly rotted and ac- 

 tively fermenting, six tons per acre ; 

 mineral phosphate, untreated, finely 

 ground, 500 lbs. per acre, composted 

 together, intimately mixed and allowed 

 to heat for several days before using, 

 applied each year from 1888 to 1897 in- 

 clusive. In 1898, 500 lbs. of Thomas' 

 phosphate was used in place of the mineral 

 phosphate. No fertilizers used from 1899 

 to 1905. In 1905 fertilizers again used as 

 in 1898 



Mineral phosphate, untreated, finely ground, 

 500 lbs. ; nitrate of soda, 200 lbs. ; wood 

 ashes, unleached, 1,000 lbs. per acre, used 

 each year from 1888 to 1897 inclusive. In 

 1898 "and 1899, 500_ lbs. of the Thomas' 

 phosphate was used in place of the mineral 

 phosphate. No fertilizers used from 1900 

 to 1905. In 1905 fertilizers again used as

 500 lbs. of the Thomas' phosphate was 

 used in place of the mineral phosphate. 

 No fertilizers used from 1900 to 1905. In 

 1905 fertilizers again used as in 1899. ....
