to some extent, on the nearness to the source. In the eastern part of 

 North Carolina and Virginia, agricultural lime, made by burning oyster 

 shells, is used, and has been found to be one of the best forms for agri- 

 cultural purposes. 



Lime may be applied in the drill and incorporated with the soil before 

 the fertilizers are distributed, or drilled on top of the row behind the 

 planter, where it will be mixed with soil in cultivation. On uplands, 

 from 400 to 700 pounds per acre is sufficient, and should be drilled. On 

 new or lowlands, 1,000 or 1,500 pounds per acre may be used with im- 

 punity, and should be broadcasted. 



It is the custom in many sections of the country to distribute land 

 plaster or calcium sulphate on the rows in late July or during August, 

 at the rate of 300 to 500 pounds per acre. Good results come from this 

 practice. 



As peanuts obtain nitrogen from the air, it is not necessary to use so 

 much of this constituent in fertilizers for this crop. The main office 

 of nitrogen, or ammonia, in a fertilizer is to produce vine, without a 

 good growth of which a large crop of peanuts cannot be obtained. Too 

 much nitrogen or ammonia in fertilizer produces vines at the expense 

 of fruit, and it is necessary to use nitrogen only in such quantities as 

 are necessary to produce a good proportion of vines to nuts. Where the 

 land will already produce sufficient vines for a good crop, all that is 

 needed, in addition to lime and plaster, are phosphoric acid and potash- 

 supplying materials, and it is suggested that 400 to 500 pounds of the 

 following mixture be employed : 



No. 1 — Acid phosphate. 14 per cent 200 pounds 



Kainit 100 pounds 



This mixture would contain, available phosphoric acid, 9.3 per cent; 

 potash, 4 per cent. Where the land needs only a small amount of nitro- 

 gen to produce an increased growth of vines, formula No. 2 is recom- 

 mended, and where a still larger growth of vines is required, formula 

 No. 3 ; and where the land is quite poor and needs a great deal of help 

 to produce sufficient growth of vines, formula No. 4 is recommended. 

 These should be applied in the drill at the rate of 300 to 600 pounds 

 per acre. 



No. 2— Acid phosphate. 14 per cent 1,100 pounds 



Cotton-seed meal 300 pounds 



Kainit 600 pounds 



2,000 pounds 



This mixture would contain, available phosphoric acid, 8 per cent : 

 ammonia, 1.10 per cent; potash, 3.8 per cent.
