be applied in the spring on both sides of the rows just 

 before the dirt is thrown back to the cane. 



A series of fertilizer experiments with sugar-cane con- 

 ducted on poor, sandy pine land in southern Georgia by 

 the United States Department of Agriculture gave results 

 which justified the recommendation of 1,100 pounds of 

 fertihzer to the acre composed of 



600 pounds high-grade acid phosphate 



100 pounds cotton-seed meal 



300 pounds nitrate of soda 



100 pounds sulfate or muriate of potash. 



Where a crop of velvet beans had been plowed under 

 the following combination of fertilizers gave best results: 



1,100 pounds high-grade acid phosphate 

 100 pounds nitrate of soda 

 100 pounds muriate of potash 



1,300 pounds, total to the acre. 



The recommendations of the Florida Station with referr 

 ence to fertihzing sugar-cane are given in the following 

 quotation:^ "On high pine land a fertilizer analyzing 

 5 per cent of ammonia, 4 per cent of phosphoric acid, and 

 8 per cent of potash, should be applied at the rate of 600 

 to 1,000 pounds per acre, ten days before planting. The 

 ammonia should come from an organic source, beqause 

 of the long season required by the crop for growing. If 

 the crop appears uneven and yellow, and shows an un- 

 thrifty appearance, it will be advisable to give a second 

 application of ammonia not later than August 1st. This 

 ammonia should be applied in the form of nitrate of soda 

 at the rate of 200 pounds per acre and broadcasted. It 

 matters little in what form the potash or phosphoric acid
