Barn-yard manure, well rotted, 15 tons per

 per acre were again used. 



XJnmanured 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' phos- 

 phate was used. No fertilizer used from 



1900 to 1905. In 1905 fertilizer again 

 used as in 1899 



Mineral phosphate, untreated, finely ground, 

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

 used each year from 1888 to 1897, in- 

 clusive. 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. lu 1905 fertiliz- 

 ers again used as in 1899 , 



Barn-yard manure, partly rotted and ac- 

 tively fermenting, 6 tons per acre ; min 

 eral phosphate, untreated, finely ground 

 500 lbs. per acre, composted together, in 

 timately mixed and allowed to heat for 

 several days before using, applied each 

 year from 1S88 to 1897, inclusive. 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 sf>da, 200 lbs.; wood 

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

 eawh year from 1888 to 1897, inclusive. In 

 189S and 1899, 500 lbs. of the Thomas' 

 phosphate was used in place of the min- 

 eral phosphate. No fertilizers used from 

 1900 to 1905. In 1905 fertilizers again 



used as in 1899 . 



8 Mineral phosphate, untreated, finely ground, 

 500 lbs.; wood ashes, unleached, 1,500 

 lbs. per acre used each year from 1888 to 

 1897, inclusive. In 1898 and 1899, 500 

 lbs. of Thomas' phosphate was used in 

 place of the mineral phosphate. No fer- 

 tilizers used from 1900 to 1905. In 1905 

 fertilizers again used as in 1899 



Mineral superphosphate, No. 1, 500 lbs. per 

 acre, used each year from 1888 to 1899, 

 inclusive. No fertilizer used from 1900 

 to 1905. In 1905 fertilizer again used as
