On a plot of ground which in 1891 received a liberal dressing of barnyard manture, a trial was made with the following three forms of phosphates, Dissolved South Carolina Bone, Dissolved Boneblack and Double Superphosphate. It was also sought to determine the effect of air-slacked lime with each form of phosphate and alone upon the soil not treated with phosphate. This

necessitated using four plots for each phosphate tested, one receiving lime only, one nothing, one the phosphate alone, and one both lime and phosphate. The table of this experiment gives the quantity of fertilizer applied and the result of the two year's experiment in full.

Taking the average of the total values of the three nothing plots (2, 6 and 10 = $46.46) and of the three plots which received lime only (1, 5 and 9 = $46.69) we have as a result of the addition of lime a gain of only 23 cents per acre.

The increase of yield over the average of the nothing plots as a result of the addition of the phosphates is for the dissolved boneblack $8.87; for the dissolved S. C. Bone, $6.51, and for the double superphosphate, $7.36.

As a result of applying lime with the various phosphates, to dissolved boneblack it increased the yield $1.69; to dissolved S. C. bone, 12 cents, and to double superphosphate, $3.02.

Though the lime has shown no decided benefit in the above experiments, its action upon the oats and clover to follow will be watched with much interest.

FERTILIZER EXPERIMENT WITH CORN, SECOND YEAR.

The experiment described in our annual report of 1891, pages 31-34, was continued the past season, using air-slacked lime and double superphosphate, as will be seen in the following table:

Comparing the yields of the nothing plots this year with the yields of last year it is found that with no addition of fertilizer the second year, the yield has increased in every case except where commercial fertilizer was applied. This is doubtless due to the more thorough decomposition of the sod and the better physical condition of the soil this year than last.

It is interesting to note the product of the nothing plots with a view of determining the lasting effects of the materials applied the previous year. Plots 2, 14 and 18 received in 1891 the same money value respectively of barnyard manure, mixed chemicals and commercial fertilizer, and nothing to either in 1892. The yield of hard corn per acre was as follows in bushels: No. 2, 50.51; No. 14, 60.47; No. 18, 58.28, the greatest yield being upon the mixed minerals, plot No. 14, group D, 2.19 bushels more than produced by the commercial fertilizer and 9.96 bushels more than from the barnyard manure. Comparing the soft corn and the stover we find in regard to the latter a difference in favor of the commercial fertilizer, the weights of stover being in the order named. No. 18, 4156 pounds; No. 2, 3017 pounds, and No. 14, 1693 pounds. In attaching a money value to the total crop the larger yield of stover on the nothing plot in group E gives the crop grown on the commercial fertilizer the greatest value, $59.21; that upon mixed chemicals second, $52.26, and barnyard manure third, $48.84. The small yield of stover on plot 14 was undoubtedly due to the fact that the nitrogen was wholly in the form of nitrate. of soda. One half the large amount of nitrogen in the form of dried blood or tankage would probably have given a larger crop -certainly more stover-and been more economical in so heavy an application.

Comparing in each group the plot receiving lime with the nothing plot, we find a gain in the yield of hard corn in all but one group-varying from 1.70 bushels in group D to 5.10 bushels in group A. The loss in group B was 2.98 bushels.

Comparing in each group the plot receiving double superphos
