loams from other parts of the piedmont, red (cecil) clays, and 

 valley lands prove them to be as rich or richer in potash than the 

 soils on which we experimented. We therefore feel safe in conclud- 

 ing that these piedmont soils, which make up the main farming area 

 of the piedmont section of the State proper, do not need potash for 

 growing peas. In like manner, analyses of the valley and main upland 

 soils of the mountains show them to be high in potash; and experi- 

 ments with other crops on the Buncombe Farm on high potash soils 

 do not respond, to any considerable extent, at least, to applications of 

 potash. For the present, at least, and until contradictory evidence is

obtained, we feel that we are safe in advising that potash is not neces- 

 sary in the growth of peas on the soils referred to above in the pied- 

 mont and mountain districts of the State. This is likely true, also, 

 of the clovers and other leguminous crops. This should mean no 

 small saving to the farmers growing this crop on these soils. The 

 yield of hay on the Iredell Farm varies from less than a ton to 

 more than three tons per acre, according to season and variety. 

 Three tons of hay would remove 30 pounds phosphoric acid, which 

 would be almost returned by 200 pounds 14 per cent acid phosphate.
