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, cow-peas, 

 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 ma- 

 terial in any of the preceding formulas be reduced one-half. Where 

 corn is to follow 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 

 regarding breaking-the land well before planting. Some doubt the 

 necessity of this for cotton. Cotton is generally grown on ridges. 

 This is necessary on wet soils, but on all fairly well drained upland 

 and sandy soils we are convinced that level and frequent shallow cul- 

 tivation, as was indicated for corn, is the best and most economical 

 method to follow, 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 fer- 

 tilizers for corn also apply to cotton, the following formulas being 

 offered tentatively and as the result of our best judgment, after study- 

 ing 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).
