Fertilizers applied each Year from 

 188!) to 1898 or 1899. No fertili- 

 zers used since. Clover sown in 

 1900 in place of the roots and 

 ploughed under in May, 1901, be- 

 fore the roots were sown.

Barn-yard manure (mixed horse and

 1S98 inclusive. No manure has 

 been applied since then 



Barn-yard manure (mixed horse and 

 cow manure) fresh, 20 tons per 

 acre each year from 1889 to 1898 

 inclusive. No manure has been 

 applied- since then 



Unmanured from the beginning 



Mineral phosphate, untreated, finely 

 ground, 1,000 lbs. per acre, used 

 each year from 1889 to 1897, in 

 elusive. In 1898 and 1899 a similar 

 weight of the Thomas' Phosphate 

 was used. No fertilizers have been 

 applied since then , 



Mineral phosphate, untreated, finely 

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

 250 lbs. wood ashes, unleached, 

 1,000 lbs. per acre, used each year 

 from 1889 to 1S97 inclusive. In 

 1898 and 1899, 500 lbs. of theTho 

 mas Phosphate was used in place 

 of the mineral phosphate. No fer- 

 ti 1 izers have been applied since then. 



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 ferti- 

 zers have been applied since then.. 



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 189S and 1899 

 1,000 lbs. of the Thomas' Phosphate 

 was used in place of the mineral 

 phosphate. No fertilizers have 



been applied since then 



8 Mineral superphosphate, No. 1, 500 

 lbs.; sulphate of potash, 200 lbs. in 

 1889 and 1S90 (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 have been applied since 

 then
