Abstract
Seedlings of five different conifer species (Cedrus deodara, Cupressocyparis leylandii, Cupressus glabra, Pinus pinea and Thuja occidentalis), interesting as ornamental plants or as reforestation plants, were grown during a vegetative period in plastic containers filled with siliceous sand and irrigated with a nutrient solution which had been previously optimized for Cupressus glabra (reference species in this assay).
The aim of this was to obtain data on nutrient levels for the four species not previously assayed and on plant nutrient requirements which could allow changing nutrient solution composition to fit the requirements of each species.
Results showed significant differences between total annual nutrient uptake levels and also in the annual time nutrient uptake distribution.
Foliar and sap analysis showed differences in nutrient contents for different species.
These results may be of interest to later fertilizer assays and mineral nutrition diagnosis for the four species tested.
