66 - The Bulletin. 



Our best results were obtained from 300 to 500 pounds of acid phos- 

 phate. We would therefore suggest the following fertilization for 

 piedmont red clay, red-clay loam, and valley soils and mountain, 

 valley and main upland soils: 



FOR LAND IN FAIR TO GOOD CONDITION. 



Acid phosphate, 14 per cent 300 to 500 pounds. 



Three hundred pounds would contain 42 pounds phosphoric acid 

 and 500 pounds 70 pounds phosphoric acid. Acid phosphate of 

 other grades can be used to supply these amounts of phosphoric acid. 



FOR POOR LAND. 



Acid phosphate, 14 per cent 300 to 500 pounds. 



Dried blood 30 to 50 pounds. 



In case acid phosphate has been used and it is found that the 

 peas are not making a satisfactory start, a side dressing of 50 to 75 

 pounds nitrate of soda may be applied to advantage. 



FOR SANDY AND SANDY-LOAM SOILS OF THE COASTAL PLAIN AND 



PIEDMONT. 



The sandy and loam soils of the eastern or coastal plain section 

 of the State, and of the piedmont, as a rule, contain much less 

 potash than the soils referred to above, though they are richer in 

 potash than in phosphoric acid. Our experiments have not gone 

 far enough to enable us to advise regarding these soils in the definite 

 way that we can regarding the red-clay loam and similar soils of 

 the piedmont and mountains, as regards fertilizer for peas. We 

 have, therefore, to use our best judgment and our own and the 

 observations of farmers in suggesting fertilizers for this crop on 

 these soils. 



FOR LAND IN FAIR TO GOOD CONDITION. 



Acid phosphate, 14 per cent 300 to 500 pounds. 



Kainit 150 to 250 pounds. 



This mixture would contain available phosphoric acid, 9.3 per 

 cent ; potash, 4 per cent. Other potash salts can take the place of 

 kainit, the muriate especially being cheaper. One pound of muriate 

 potash is equal in fertilizing value to four pounds of kainit. 



FOR POOR LAND. 



Acid phosphate, 14 per cent 300 to 500 pounds. 



Kainit - 150 to 250 })0unds. 



Dried blood 30 to 50 pounds.
