 nitrogen. Use a ton of this on land that is considered 

 fertile enough for an ordinary crop ; two tons may be ap- 

 plied on land that has been cropped several years.

If your soil is stiff, heavy or a red clay, use one con- 

 taining 8 per cent, available phosphoric acidj 5 per cent, 

 potash, and 5 per cent, nitrogen. If you want to make a 

 full crop you should use from 1,000 to 2,000 pounds of 

 high-grade fertilizer per acre. A word of caution, how- 

 ever, about commercial fertilizers. They should always 

 be put in the ground two or three weeks before the seed is 

 sown. As soon as these fertilizers go in the ground and 

 come in contact with moisture a chemical change begins. 

 While that change is taking place heat is generated which 

 usually continues for some two weeks. If seed comes in 

 contact with the fertilizer while this chemical change is 

 taking place the vitality is "burned out" of the seed and 

 it will not germinate. This is especially true here in the 

 South where cottonseed-meal is so largely used as a source 

 of nitrogen in the fertilizers. Thousands of pounds of 

 seed are "burned up" in this way every year and the
