EXPERIMENTS WITH FERTILIZERS ON PLOTS OF MANGELS AND TURNIPS. 



Fertilizers .ipplied each vear from 

 188i) to 1898 or 1899. No' fertilizers 

 used since. Clover sown in 1900 

 in place of the roots and ploug^hed 

 under in May, 1901, before the 

 roots were sown. In 1903 clover 

 was again sown and ploughed 

 under in Maj', 1904. 



Barn-yard manure (mixed horse and 

 cow manure) well rotted, 20 tons 

 per acre each year from 1889 to 

 1898 inclusive. No mani;re has 

 been applied since then 



Barn-yard manure (mixed horse and 

 cow maniire) fre.sh, 20 tons per 

 acre each year from 1889 to 1898 

 inclusive. No manure has been 

 ai)plied 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., nitr.ate of soda, 

 250 lbs. wood ashes, unleached, 

 1,000 lbs. per 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 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 daj'^s before using, applied 

 each year from 1889 to 18CI7 inclu 

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

 phosphate was used in place of 

 the mineral phospliate. No fertili- 

 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 muiiate 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 

 1,00C lbs. of the Thomas' phosphate 

 was used in place of the mineral 

 phosphate. No fertilizers have 

 been applied since then 



Mineral superphospliate. No. 1, 500 

 lbs.; sulphate of potash, 200 lbs. in 

 1889 and 1890 (substituted by mur- 

 iate of potash, 2.50 lbs. in 1891 and 

 subsequent years) ; nitrate of soda,| 

 200 lbs. per acre, used earh j'earl 

 from 1889 to 1899 inclusive. No 

 fertilizers have been applied since| 

 then
