Název v původním jazyce

Comparison of soil carbon transformation under turf and in arable soil

Popis výsledku v původním jazyce

As far as the soil richness and the creation of humus acids as well as from the point of view of sufficient energy supply to soil microorganisms, decomposable carbon Cdec is of great importance. This carbon has about 15 times higher value than "active" carbon Chws determined in soils leached with hot water. We have suggested to amend the datum on Chws by assigning a speed constant k1 of mineralisation of the decomposable part of organic matter and calculated from the data obtained by measuring biochemical oxygen demand (BOD) of soil suspensions using the system Oxi Top Control produced by WTW Merck. This work presents the results obtained from the equally fertilized sand-clay cambisoil in the variant with natural turf and in the variant arable soil with repeated circulation of winter wheat. The turf variant contains less organic matter than the arable soil, it contains more Chws though. The instability of decomposable part of soil organic matter is higher in the turf variant.
