POTATOES 
Potatoes are rapidly becoming an important garden crop, not 
only on the farm, but also in the city and town gardens, and more 
space should be devoted to them. They yield more food for a 
given space than almost any other vegetable grown, and have the 
additional advantage of long keeping qualities. 
Soil 
In general, the best soil for potatoes is a deep,' sandy loam, 
underlaid by a porous sub-soil. The character of the sub-soil is 
important. Even the heavier soils are often productive when the 
sub-soil is gravelly or open. Heavy soils which easily become 
puddled are not suitable for potatoes unless large quantities of 
well-rotted manure are applied, and the soil is plowed deeply or 
spaded in the fall. 
Preparation of Soil 
The preparation of the soil for potatoes should be thorough 
and deep, in order that the plant may have a large feeding area. 
Potatoes should never he grown more than once in succession on 
the same soil, and this is difficult to avoid on small areas. On the 
farms where a regular system of crop rotation is practiced, this 
difficulty is easily overcome. In garden practice, where farm ro¬ 
tation is not possible, rotation of vegetables from one piece of the 
garden to another is advisable. In order to supply the needed 
vegetable matter and fertility, the land should be given a heavy 
top dressing of stable manure. The older and more decomposed 
this manure, the better it is. On heavy soil, the manure should 
be applied in the fall and plowed or spaded into the land. The 
plowing or spading for potatoes should be 10 to 12 inches deep^ 
to permit the root system to penetrate as deeply as possible. The 
land should be cross-plowed or spaded again in the spring a few 
days before planting. On lighter soil, the manure and the plowing 
may be deferred until spring, but the application of the manure 
and the plowing should be done sometime before planting. The 
land should not be plowed or worked while wet. 
Planting 
For garden purposes, the planting may be done by hand. A 
line is stretched across the lot, and a furrow or trench is opened
