EXPERIMENTAL FIRMS 



1-2 EDWARD VI!., A. 1902 



using about 24 pounds of seed to the acre and thinning the plants, when up, to 6 or 8 

 inches, and the No. 2 in hills 3 feet apart each way and 4 or 5 kernels in a hill. During 

 the past seven years both sorts have been grown in hills. 



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

 their 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 1901, on May 25, 

 and cut for ensilage on September 12.

 Clover sown in 1!)00 in place of the corn

 the corn was planted.

Mineral phosphate, untreated, finely ground, 

 800 lbs. per acre, used each year from 

 188S to 1897 inclusive. In 1898 and 1899 

 a similar weight of the Thomas' Phos- 

 phate was used. No fertilizers have been

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, 800 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- 

 tively fermenting, 6 tons per acre ; mineral 

 phosphate, untreated, finely ground, 500 

 lbs. per acre, composted together, intim 

 ately mixed and allowed to heat for 

 several 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 

 18!)8 and 1899 500 lbs. of the Thomas' 

 Phosphate was used in place of the 

 mineral phosphate. No fertilizers have 

 been applied since then
