certainly not to the extent that it docs on li^ht soils. A small amount 

 of nitrate of soda in the mixture will give the crop a ([uick start and 

 make its cultivation easier and more economical. Formula No. '6 

 has been arranged with this idea in view, and in No. 2 one-half the 

 nitrogen comes from nitrate of soda. On light lands it would likely 

 be better to omit the nitrate from the mixture and apply it as a top 

 dressing between the tenth and last of June on early corn. Nitrate 

 of soda may take the place of a portion of the other nitrogen-furnish- 

 ing materials in any of the formulas, one pound of nitrate being- 

 equal in its content of nitrogen to 2.2 pounds of cotton-seed meal, 

 2 pounds of fish scrap, 1.2 pounds of dried blood. Nitrate of soda 

 is frequently used as a top dressing for corn and is a very valuable 

 material for use in this way. A good application is 50 to 75 pounds 

 per acre, distributed along the side of the row or dropped beside the 

 plants and three or four inches from them, or else where there is a 

 ridge in the center it may be distributed on this, and when it is thrown 

 out the nitrate will be thrown to the two sides of the row. 



Application of Fertilizers to Corn. — On clay lands and loams hav- 

 ing good subsoil the fertilizer should be applied in the drill, at or 

 just before planting, at the rate of 200 to 400 pounds per acre. On 

 light sandy lands 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 begiin to grow well. 



Fertilizers for Cor7i Following Peas and Other Legumes. 



The best and most profitable yields of corn in our experimental 

 work were where the corn follow^ed velvet beans, bur clover, cow-peas 

 and crimson clover and other leguminous crops. These crops, with 

 acid phosphate and kainit, or some other potash salt, are the best pre- 

 vious treatment and fertilization for corn. Where light crops of peas 

 have been gTown in corn, or cut from the land and the stubble left, it 

 would be safest to add some nitrogenous material in the fertilizer mix- 

 ture. 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 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 mix- 

 ture, in the drill, be used just before planting : 



Acid phosphate 200 pounds 



Kainit 100 pounds

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
