EXPERIMENTAL FARMS 



2-3 EDWARD VII., A. 1903 



In 1900 no crop of Indian corn was grown on these plots, but clover was sown in 

 its place on May 5 in the proportion of twelve pounds per acre. This made a strong 

 growth was cut twice during the season and left on the ground to decay so that when 

 ploughed under the land might get the full benefit of the clover crop. The clover was 

 allowed to remain growing until May 20, 1901, by which time it had made a very heavy 

 growth. It was then ploughed under about six inches deep, and harrowed well before 

 the corn was planted. The corn in both series of plots was planted in 1902, on May 26, 

 and cut for ensilage on September 25.

Fertilizers applied each year from 1888 to 

 1898 or 1899. No fertilizers used since, 

 Clover sown in 1900 in place of the com 

 and ploughed under in May, 1901, before 

 the corn was planted. 



Barn-yard manure (mixed horse and cow 

 manure) well rotted, 12 tons per acre, 

 each year from 1888 to 1898 inclusive. 

 No manure has been applied since then. . 



Barn-yard manure (mixed horse and cow 

 manure) fresh, 12 tons per acre each year 

 from 1888 to 1898 inclusive. No manure 

 has been applied since then 



Unmanured from the beginning 



Mineral phospliate,untreated, finely ground 

 800 lbs. per acre, used each year from 

 1888 to 189r inclusive. In 1898 and 1899 

 a similar weight of the Thomas' phos- 

 phate was used. No fertilizers have been 

 applied since then 



Mineral phosphate,untreated,finely ground, 

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

 used each year from 1888 to 1897 inclusive. 

 In 1898 and 1899, 8C0 lbs. of the Thomas' 

 phosphate was used in place of the mineral 

 phosphate. No fertilizers have been 

 applied since then 



Barn-yard manure, partly rotted and ac 

 ti vely fermenting, G tons per acre ; mineral 

 phosphate, untreated, finely ground, 500 

 lbs. per acre, composted together, intim 

 ately mixed and allowed to heat for 

 Bcveral days before using, applied each 

 year from 1888 to 1897 inclusive. In 1898 

 500 lbs. of Thomas' phosphate was used 

 in place of the mineral phosphate. No 

 fertilizers have been applied since then. . 



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' phos- 

 phate was used in place of the mineral 

 phosphate. No fertilizers have been ap- 

 plied since then
