Experiments with corn, M. A. Scovell, M. S. — These include 

 (1) experiments on the station farm in continuation of a series begun 

 in 1888, and reported in Bulletin No. 17 of this station (See Experiment 

 Station Record, Vol. I, p. 61); and (2) co-operative experiments with 

 fertilizers for soil tests on farms in other parts of the State and on dif- 

 ferent geological formations. 



Experiments on the station farm. — " The soil of the experiment station 

 farm is what is termed a 'blue-grass' soil. It is derived from the 

 lower Silurian limestone, rich in phosphoric acid. The subsoil is a 

 light-colored clay, so retentive as to make the soil deficient in natural 

 drainage. The land is worn, having been in cultivation for many 

 years. It is believed that no stable manure or other fertilizers were ap- 

 plied before the farm was purchased by the station." The season was 

 favorable for corn in respect to both temperature and rain-fall. 



Effects of fertilizers containing nitrogen, phosphoric acid, and potash. 

 Experiment ]:so. 1. — Nitrate of soda, 100 pounds per acre, dissolved bone- 

 black (acid black), 320 pounds per acre, and muriate of potash, 160 

 pounds per acre, singly, two by two, and all three together, and land 

 plaster, 160 pounds per acre, were applied on parallel plats of one tenth 

 acre each, two plats being left unmanured. The experiment was a 

 repetition of the one in 1888, with the same fertilizers on the same plats, 

 except that the quantities were adjusted to the schedule proposed in
