Counteracing the negative effects of simulated acid rain on the development of Larix decidua MILL. seedlings by means of mineral fertilization (NPK)
AbstractThe experiment was aimed at estimating the effect of mineral fertilization with ternary mineral fertilizers (NPK) on the development of Larix decidua Mill. seedlings remaining under the influence of simulated acid rain. The soils with a mechanical composition of poor loamy sands were treated with water solutions of H2SO4 of pH: 2.5, 3.0, 3.5, 4.0, 4.5, 7.8. and selected biometric features were measured. The experiment was carried over a period of 2 yr. The analysis of changes in the biometric features demonstrated that the poor alkaline reaction of water solutions (7.8), and strong acid (2.5) has a negative effect on the development of the Larix decidua Mill. seedlings, resulting in the limitation of the length increment, decrease in the mass of seedlings, mass of needles etc. Optimal development of the seedlings was at pH 4.0. A decrease in the biometric features analyzed together with an increase in the acidity of water solution was observed.
