loams it is best to use 50 to 100 pounds in the drill at time of planting, 

 to give the crop a good start, and the balance of the fertilizer as a side 

 dressing when the corn has begun to grow well. 



Fertilizers for Corn Following Peas and Other Legumes. 



The best and most profitable yields of corn in our experimental work 

 were where the corn followed velvet beans, bur clover, cowpeas, crimson 

 clover and other leguminous crops. These crops, with acid phosphate 

 and kainit, or some other potash salt, are the best previous treatment 

 and fertilization for corn. Where light crops of peas have been grown 

 in corn, or cut from the land and the stubble left, it would be safest to 

 add some nitrogenous material in the fertilizer mixture. In cases of 

 this kind it is suggested that the nitrogen-furnishing material in any 

 of the preceding formulas be reduced one-half. Where corn is to fol- 

 low good crops of velvet beans, peas, bur and crimson clover or soja 

 beans, especially where the entire crops have been left on the soil, no 

 further application of nitrogen need be made, but it is advised that 200 

 to 300 pounds per acre of the following mixture, in the drill, be used 

 just before planting: 



Acid phosphate 200 pounds 



Kainit 100 pounds 



COTTON. 



Culture. — The remarks regarding the preparation and cultivation of 

 corn also apply with equal force to cotton, unless it be the part regard- 

 ing breaking the land well before planting. Some doubt the necessity 

 of this for cotton. Cotton is generally grown on ridges. This is nec- 

 essary on wet soils, but on all fairly well-drained upland and sandy 

 soils we are convinced that level and frequent shallow cultivation, as 

 was indicated for corn, is the best and most economical method to fol- 

 low in growing cotton. Eidge culture may give better results in very 

 wet years, but, taking the seasons as they come, the advantage will lie, 

 we think, with flat culture. 



Fertilizers for Cotton. — The preliminary remarks regarding fertil- 

 izers for corn also apply to cotton, the following formulas being offered 

 tentatively and as the result of our best judgment, after studying the 

 best obtainable data on this subject : 



For Cotton on Land in Fair Condition. 

 No. 1— 



Acid phosphate, 14 per cent phosphoric acid 895 pounds 



Cotton-seed meal. 6.59 per cent nitrogen, 2.5 per cent phos- 

 phoric acid and 1.5 per cent potash 790 pounds 



Kainit, 12.5 per cent potash 315 pounds 



2,000 pounds 



This mixture will contain : available phosphoric acid, 7.2 per cent ; 

 potash, 2.6 per cent; nitrogen, 2.6 per cent (equal to ammonia, 3.2 

 per cent).
