I am interested in learning about the special content of North Carolina soil. For example- why does tobacco grow so well, what would have to be done to the soil to make it good for other crops, etc?
(from S. Buol) – First, there are over 400 different soils in North Carolina and only a few are good for tobacco. Even tobacco requirements differ between flue cured tobacco and burley tobacco. The requirements for flue cured are the most specific. To obtain high yields of the best quality flue cured tobacco a grower needs to grow a big plant that becomes nitrogen deficient near maturity. This is best done in the well drained Kandiudults of the middle and upper coastal plain areas of the state. The soil conditions best suited are a sandy surface about 10 to 15 inches thick over a sandy clay loam subsoil. The sand surface should have a low organic matter content so the little nitrogen is available through organic matter decomposition late in the summer. There growers provide abundant nitrogen early in the growing season as a soluble inorganic nitrate that is easily taken up by the plant but only enough nitrogen for early growth is provided and the “golden leaf” of maturity is in part ye
