CORN TILLAGE 181 



bunching for tassel. Lay by early . . . (Fig. 91). No hoeing 

 should be necessary. 



"On sandy soils I would use for a 25-40 bushel yield, 100 

 pounds acid phosphate, 100 pounds cotton-seed meal and 200 

 pounds kainit per acre, mixed, and 75 pounds nitrate of soda at 

 last plowing, leaving corn 16-20 inches in drill, rows 6 feet apart.

 ING TO THE WILLIAMSON PLAN. 

 (Redrawn after Mr. Williamson's diagram.) 



For 40-60 bushel yield, I would double the amount of mixed 

 fertilizer, and also use 125 pounds of nitrate of soda, leaving corn 

 14-16 inches in drill, rows 6 feet apart. Clay land is said to 

 require more phosphoric acid and less potash." 



In the majority of experiments published prior to 1910, 

 and made at the South Carolina, Alabama, and Georgia 

 Experiment Stations, the yield of corn was less under the 

 Williamson method than with the best of the methods with 

 which it was compared and in which equal amounts of 

 similar fertilizers were employed. However, when various 

 modifications of the Williamson method have been applied 

 by farmers, frequently without notably stunting the corn, 

 large yields have often resulted, as has likewise been 

 the case when farmers have employed any other system
