Study of the dynamics of the organic matter content of soil samples of two different forests, in different plots, under three different uses of the soil

Abstract

[EN] Presented thesis focuses on the dynamics of soil organic matter on sites with different silvicultural management systems. Coppice, coppice-with-standard and high forest plots were compared in terms of soil organic matter. The study was conducted between the winter of 2016/17 and the winter of 2018/19 at the university Masaryk forest training ground Krtiny on pre-existing TARMAG research sites near Brno, Czech Republic. The samples were collected during four different calendar seasons over a full two-year period, which allowed for the evaluation of the seasonal and year-to-year dynamics of soil organic matter content. The evaluation detected a significant effect of the type of management on the soil organic matter stock fluxes and shows that coppiced plots are the most capable of soil organic matter accumulation. However, its soil organic matter gains in topsoil are compensated by losses in deeper layers.

[CA] Vaig a investigar el contingut de la matèria orgànica en moltes mostres de sòl. Prendré les mostres de 3 diferents parcel·les de 2 boscos diferents i també de 3 usos diferents a cada parcel·la. Amb aquestes dades comprovarem si el contingut de la matèria orgànica està relacionat amb la quantitat de microorganismes, incloent les dades en gràfics.
