FIELD EXPERIMENTS WITH FERTILIZERS. 201 
Experiments of r899.—Potatoes were grown in the soil tests 
of 1899. This is the third time this crop has been grown in 
this series of experiments. Two early varieties of potatoes 
were planted: ‘‘ Fortune’’ on the set of plots on the north side 
of the field, and ‘‘ Queen”’ on the set on the south side. In 
the early part of the season all the plants made a “‘ full stand ’”’ 
and a fairly even growth; but, as the season advanced, quite 
striking differences were noticed in the growth on the different 
plots. Throughout the latter half of the season there was a 
healthier and more vigorous growth of plants on the plots upon 
which potash was applied. The beneficial effect of the potash 
upon this crop in this experiment is indicated by a comparison 
of the results from plots A, B, and C with each other, and also 
those from plots D, E, and F, as given in Table 49 below.
