9. Increasing the amount of the normal fertilizer application 

 increased the yields and the profits, the best yields, on the whole, 

 coming from the applications of 300 to GOO pounds. 



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 amounts decrease the yields. 



11. Nitrogen has added but slightly to the yields, and there is 

 no advantage in using it on this soil, when in fair to good condition. 



12. 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. 



13. The most profitable 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. 



14. In growing 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 need 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 other nitrogen-furnishing material may 

 be added which will supply sufficient nitrogen to make 1 per cent 

 nitrogen in the fertilizer mixture. Where 300 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. 

 If it is discovered after the peas are planted and up that there is 

 a need of nitrogen, as indicated by small, slow growth and pale^ 

 sickly appearance, a top dressing of 50 to 75 pounds of nitrate soda 

 can be applied with profit. 



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

 experiments on the Buncombe Test Farm indicate that these re- 

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

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

 the mountain sections of the State. These soils constitute the main 

 farming soils of the piedmont and mountain districts, and an ap- 

 plication of the results will mean no small saving in the fertilizer 

 bills of the farmers operating on these soils.
