Soil organic matter of Chernozem in the part of Central Europe

Abstract

In this study, we have tried to evaluate the current contents of Soil Organic Matter (SOM) in the Soil Type Chernozem for Central Europe and to determine the site specific level for the Czech Republic. In the past, the observed effect of SOM on the Agronomic characteristics in particular yields. Nowadays it means a very important influence on the Environment, particularly in the terms of ecological functions of soil (the influence of the filter function, sanitation function, protection against degradation etc.). The statistical analysis included data for all the Chernozems (N = 141) regardless of subtype derived from measurements from 2003 to 2006. Measurements were carried out at selected locations in the Czech Republic.Profiles at each site were divided into topsoil and subsoil and these were separately statistically processed. When evaluating the frequency distribution, we suppose that the anthropic un-affected Soils would be approximately equal to distribution Gauss normal distribution, and both frequency distribution (in topsoil and subsoil) will be similar (mollic horizon in this Soil Type on non-eroded land is relatively deep and homogeneous).Next from of the observed properties is relation between Content of Soil organic Matter and the texture, namely the content of particles smaller than 0.01 mm. The average SOM content is higher in clayey soil, clay-loam soil than in sandy soil. Differences between soil sandy-loam and clayey-loam are statistically significant. The paper also outlined the possible future development of SOM on Chernozem soils.
