Fertilizers applied each year from 

 1889 to 1898 or 1899. No fertilizers 

 used from that time to 1905. Clover 

 sown in 1900 in place of the roots 

 and ploughed under in May, 1901, 

 before the roots were sown. In 1903 

 clover was again sown and plough- 

 ed under in May, 1904. In 1905 

 fertilizers again applied as in 1899.' 

 Clover discontinued. 



Mineral phosphate, untreated, finely 

 ground, 1,000 lbs., nitrate of soda, 

 250 lbs., wood ashes, unleached, 

 1,000 lbs. psr acre, used each year 

 from 1889 to 1897 inclusive. In 



1898 and 1899 500 lbs. of the Tho- 

 mas' phosphate was used in place 

 of the mineral phosphate. No ferti 

 lizers used from 1900 to 1905. In 

 1905 fertilizers again used as in 1899. 



Barn-yard manure, partly rotted and 

 actively fermenting, 6 tons per 

 acre ; mineral phosphate, untreated, 

 finely ground, 1,000 lbs. per acre, 

 composted together, intimately 

 mixed and allowed to heat for 

 several days before using, applied 

 each year from 1889 to 1897 inclu- 

 sive. In 1898 1,000 lbs. of Thomas' 

 phosphate was used in place of 

 the mineral phosphate. No fertili- 

 zers used from 1899 to 1905. In 

 1905 fertilizers again used as in 

 1898 



Mineral phosphate, untreated, finely 

 ground, 1,000 lbs. ; sulphate of 

 potash, 200 lbs. in 1889 and 1890 

 (substituted by muriate of potash, 

 250 lbs. in 1891 and subsequent 

 years); nitrate of soda, 200 lbs. per 

 acre, used each year from 1889 to 

 1897 inclusive. In 1898 and 1899 

 1,000 lbs. of the Thomas' phosphate 

 was used in place of the mineral 

 phosphate. No fertilizers used 

 from 1900 to 1905. In 1905 fertili- 

 zers again used as in 1899 



Mineral superphosphate, No. 1, 500 

 lbs. ; sulphate of potash, 200 lbs. in 

 1889 and 1890 (substituted by mur- 

 iate of potash, 250 lbs. in 1891 and 

 subsequent years) ; nitrate of soda, 

 200 lbs. per acre, used each year 

 from 1889 to 1899 inclusive. No 

 fertilizers 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 

 1889 to 1899 inchisive. No fertili- 

 zer used from 1900 to 190.5. In 

 1905 fertilizer again used as in 1899| 



Nitrate of soda, 300 lbs. per acre, 

 used each year from 1889 to 1899, 

 inclusive. No fertilizer use from 

 1900 to 1905. In 1905 fertilizer used 

 again as in 1899. 



Sulphate of ammonia, 300 lbs. per 

 acre, used each year from 1889 to 



1899 inclusive. No fertilizer used 

 from 1900 to 1905. In 1905 fertili- 

 zer used again as in 1899
