2 For Plots 0, 1, 20, 21, and 22, the averages are for only 19, 18, 17, 13, and 13 years 
respectively. 
3 On Plots 17 and 18 the manures have alternated during the last 12 years; that is, ammonia- 
salts on Plots 17, and the mixed mineral manure on Plots 18, in one year; mineral manure on 
Plots 17, and ammonia-salts on Plots 18, in the next year, and so on.
