| Abstract:
A survey was carried out on the productivity of ash-tree manna in relation to the following basic parameters: a) levels of fertility elements in the leaves; b) soil-plant fertility element relationship. Results obtained by comparing the yields from four different test areas are given. The most important aspect which emerged was that whatever the amount of nutrients in the soils, including "poor" conditions, the coresponding level of the same elements in the leaves doesn't seem to be influenced. | |
