10. Taking all the experiments into consideration, they show 

 that this soil does not need potash for the most profitable production 

 of peas, and that large amomits decrease the yields. 



11. Phosphoric acid is the most needed constituent on this soil. 

 The analysis of the soil shows that it is very low in phosphoric acid. 

 Field tests and chemical analysis of the soil are therefore in entire 

 harmony in showing the need of this soil for growing peas. 



12. The most prolitable yields have been obtained from the use 

 of 300 to 500 pounds of 14 per cent acid phosphate per acre, or -42 

 pounds to 70 pounds phosphoric acid. 



13. In growdng peas on the above land we advise the use of 

 phosphoric acid alone as stated above, 300 pounds acid phosphate 

 being a good application and 500 pounds not too much. No potash- 

 supplying material should be employed. In case the land is very 

 poor, so that the peas do not start well at first, an amount of cotton- 

 seed meal, dried blood, or some other material may be added which 

 will supply sufficient nitrogen to make 1 per cent nitrogen in the 

 fertilizer mixture. Where'oOO pounds and 500 pounds of 14 per 

 cent acid phosphate respectively are used 25 pounds and 42 pounds 

 of blood will supply the necessary nitrogen. 



14. Our soil analyses of the various type soils of the State and 

 experiments on the Buncombe Test Farm indicate that these results 

 will apply to the red (cecir) clay loams, red (cecil) clays and valley 

 soils of the piedmont and valley and main upland soils of the 

 mountain sections of the State.
