greatly prefer them to others containing less potash. It takes con- 

 siderable observation and experimentation to determine the best practice 

 in matters of this kind. 



Formula No. 7, in 1905, in some tobacco experiments conducted on 

 the bright-leaf soils of Granville County, gave very promising results. 

 Three hundred and eighty-eight pounds per acre of this mixture were 

 used, which was equal to an application of 600 pounds of a mixture 

 analyzing 4 per cent available phosphoric acid, 6 per cent potash and 

 4 per cent ammonia. 



A limited quantity of stable manure is very beneficial to tobacco, and 

 it succeeds well after peanuts. These materials add ammonia to the 

 soil, and where heavy applications of fertilizers are to be made in con- 

 nection with manure, and on peanut land, it would be well not to have 

 so much ammonia in the fertilizers as is used in the ones employed on 

 land not having other ammoniated materials put on them. Formula 

 ISTo. 5 is destined to meet cases of this kind. A good many eastern to- 

 bacco growers plant tobacco after peanuts, and some of them grow peas 

 between the hills of tobacco, planting them with hoes and putting six 

 to ten peas in a place, the latter part of June or early in July. This 

 improves the soil for after-crops, but tobacco grown after tobacco and 

 peas is said not to be of good quality, though, as would be expected, 

 the growth is very large. 



Good results will come from the use of high-grade fertilizers, such 

 as are suggested above, or similar ones, and we believe that when once 

 tried there will be no inclination to go back to the lower-grade ones, 

 now so largely used.
