Abstract

There are chestnut forests having a marked variation in growth rate in the Yangju and Tangjin districts. Soil samples and chestnut foliage collected from the two districts were analyzed for several elements. The soil nutrients have no relation with the height growth of the chestnut trees in the two districts, however, the levels of foliar nitrogen and phosphorus were significantly correlated with the height growth of the chestnut trees. Foliar nitrogen and phoshporus displayed an inverse correlation with the soil calcium level. So it can be said that the level of soil calcium indirectly governs the height growth of the chestnut trees.
