FIELD EXPERIMENTS WITH FERTILIZERS. -I131 
of fertility. The land is not quickly affected by drought, and 
appears to retain fertilizers readily. The natural drainage is 
good. 
A crop of mixed meadow grasses was grown on the field in 
1893 before the Hungarian experiment was started. This was 
cut and harvested June 8th—rith, and the field was plowed a few 
days later preparatory to the experiment. The crop of hay con- 
sisted mostly of fine grasses, except there was in addition some 
clover on plots 64, 13, 14 and 15. The yield was about one ton 
per acre. 
Owing to the severe drought at this period, it was thought 
advisable not to sow the seed at once. Hence the soil was simply 
kept free of weeds by harrowing several times, till July 8th, at 
which time the experiment was started. 
NOTES DURING GROWTH. 
The field was sown with Hungarian grass July 8th, at the rate of one bushel 
per acre. The fertilizer was applied after sowing the seed, and the land was 
then rolled. Light rains July 9th and 12th caused the seed to germinate fairly 
well. July 31st the field was found to be fairly well stocked, and the Hungarian 
was two to three inches high. At this date very little difference could be 
observed in the growth on the different plots. 
August 8th the crop was 7 to Io inches high on all of the fertilized plots, and 
appeared heavier and darker colored on the plots having had the larger quantities 
of nitrogen. The growth on the nothing plots was small, thin and pale-colored, 
and on the mixed mineral plots was slender and pale-colored. The growth on 
plots 8 and 9 was somewhat uneven. 
August 28th the crop was nearly grown and beginning to blossom. The 
growth on the fertilized plots seemed to be about twice as heavy as on the mixed 
mineral plots. ‘The growth seemed heavier and darker green where the most 
nitrogen was used. The heaviest growth appeared to be on the sulphate of 
ammonia plots. The crop on the nothing plots was small, pale and thin, while 
that on the mineral plots was pale in color, but somewhat heavier than on the 
nothing plots. Plot 6d showed a much heavier growth than 6a. 
The crop on the strips between the plots was cut and removed 
August 31st-Sept. 2d. The crop on the plots was cut Sept. 4th. 
At this time it was noticed that the growth on plots 8 and g was 
quite uneven, and that plot 64 showed a heavier crop than 6a. 
The Hungarian was a little past full bloom when cut. 
RESULTS OF THE EXPERIMENTS. 
In the diagram which follows, the comparative yields per acre 
are shown. The field weights for each plot are calculated to a 
uniform water basis of 11 per cent. moisture (89 per cent. dry 
matter).
