Effect of logging residues processing and mechanical soil preparation on the content of selected elements in a forest soil as measured by X-ray fluorescence spectrometry

Popis výsledku v původním jazyce

Elementary composition of soil is an important factor of the behaviour of forest ecosystem and sustainability of forest production. It can be influenced by forest management. This contribution presents a comparison of different logging residues processing on the content of selected elements in a forest soil determined by X ray fluorescence (XRF) spectrometry. A field experiment was established on natural pine stands with sandy Podzol (Spodosol) soils in Central Bohemia. Four types of logging residues processing were applied after final harvest (1) burning of logging residues in the terrain, (2) removal of logging residues, (3) bunching of logging residues into heaps, and (4) chipping of wood residues in the terrain. Large scale soil preparation with forest plough was performed. A half of the plots were additionally fertilized with wood ash. Soil samples were collected three years after the treatment and planting new trees from the uppermost soil layer (0 to 5 cm), they were air dried and measured with a portable XRF spectrometer Delta Premium. Bunching of residues into heaps led to a decrease of As, K, Fe, Mn, Pb and Zn in soil. Burning of logging residues increased the content of As, Fe, Zn and Pb. Surprisingly, residues removal did not cause a significant decrease of most elements in the soil. Chipping of wood residues in the terrain did not led to a significant decrease or increase of the content of most elements. Additional fertilization with wood ash increased the content of most elements, except Si and Mo. Management of logging residues was shown to be a crucial factor of soil element composition. XRF spectrometry proved to be a fast method for the determination of element content in soils. However, numerous elements were mostly under the detection limit of the instrument (including Ca and Mg).
