Lime With A Complete Fertilizer, N P K L (Plats 93, 73 and 63). When lime was used in combination with the fertilizer constituents there was less corn produced on the plat in "Old" Field than where the three fertilizer constituents were used without lime, but on the plats on Fields A and B there was a decided gain for the use of lime all three jears. For the average of two years on "Old" Field lime and complete fertilizer gave an annual loss of $8.89, but on both A and B it was applied with a decidedly greater profit than a complete fertilizer alone. The reduced yield in "Old" Field is due largely to the lack of uniformity of the land. From an average of all the results the following is evident: (1) That nitrogen and phosphoric acid gave an average increase of 3.6 bushels of corn in each of the three fields. This increase in grain was not enough to pay for the fertilizer but when the increase in stover is also considered the application gave the small profit of 60 cents. (2) That nitrogen and potash gave even a smaller average increase than did nitrogen and phosphoric acid; this increase being only 2.1 bushels. Considering the grain alone this represents a loss of 84 cents and a profit of 23 cents when stover also is included. (3) That phosphoric acid and potash fail to give an increase on any of the fields and consequently was in all cases applied at a financial loss.

(5) That...show more
