POTATO 215 



applied to the ground before planting the crop. Some 

 growers apply the fertilizer broadcast before sowing, 

 and harrow it in; many cast it directly in the row and 

 cover it with earth before dropping the seed-pieces. In 

 any case it should not be allowed to touch the seed- 

 pieces. 



The mixture may contain nitrogen three per cent, 

 preferably as nitrate of soda; phosphoric acid six percent, 

 preferably as dissolved boneblack or superphosphate; 

 and potash ten per cent, preferably as sulphate of 

 potash. 



Or, using a different formula, an application of 

 1,300 pounds per acre may be given by a mixture of 

 100 pounds nitrate of soda, 300 pounds cotton-seed 

 meal, 200 pounds ground bone, 400 pounds acid 

 phosphate, 300 pounds sulphate or muriate of potash; 

 the formula being nitrogen 3 per cent, phosphoric acid 

 3 per cent, potash 12 per cent. It should be remarked 

 that the sulphate of potash gives a better-looking Potato 

 than the muriate. 



Voorhees remarks that for late Potatoes, having a 

 longer period of growth and usually grown on heavier 

 soils, applications of 600 to 800 pounds per acre may 

 prove enough, the formula to be nitrogen 2J per cent, 

 phosphoric acid 6 per cent, potash 8 per cent. 



Harvesting. The early crop may be dug when the 

 Potatoes are of marketable size. Very early Potatoes 

 may be got for the home table by carefully digging a
