The Effect of «Acid Rains» and Mineral Fertilization on the Development of Biometrical Features of Fagus sylvatica L. Seedlings

Stanisław Małek , Jan Greszta


The purpose of the present experiment was to describe the influence of various methods of mineral fertilization: NK into leaves (Florovit), NPK onto soil (Fruktus 2) and liming (dolomite magnesium) on the development of Fagus sylvatica L. seedlings subject to the influence ofsimulated acid rains of pH 2.5, 3.0, 3.5,4.0, 4.5. As a result of the carried out analysis of the correlation coefficient a reciprocal high correlation was found between particular parameters of growth of Fagus sylvatica L. seedlings i.e. of the diameter of root nect, root mass, total mass of: seedlings, leaves, main shoots, lateral shoots, ligneous parts, overground parts, as well as of total length of lateral shoots. Whereas no high correlation was observed between the above mentioned parameters and a total heigth of the seedling. The obtained results of the analysis of changes in biometric characteristics of Fagus sylvatica L. seedlings showed, that the best development was achieved at pH 4.5, whereas their weakest development was observed at 2.5. The analysis showed the decrease in values of analysed characteristic together with the increase in acidity of aqueous solutions. The first and second and third year of the experiment for Fagus sylvatica L. showed that kind of fertilization did not effect positively the increase in values of the analyzed biometrical feature - total height of seedling comparing with those of control plots. The significant improvement of total height of seedling was noticed on control plot with pH 3.5 in relation to pH 2.5 on control plot in first year. The best increment oftotal height ofseedling was noticed for pH 3.5 for each year. The third year ofthe experiment showed that using fertilization: Ca + Mg onto soil, NK into leaves and NPK onto soil it is possible to restrict the unfavourable influence of «acid rains» on total mass of Fagus sylvatica L. seedling. The best significant increment of this biometrical feature was observed on pH 4.0. When one wants to restrict the unfavourable influence of «acid rains» on analyzed total mass ofseedlings within pH 2.5-4.5 it is possible to choose optimaly one from three applied fertilizing variants.
