Biochemical properties of soils of acidified mountain ecosystems
Šantrůčková, Hana ; Kopáček, Jiří ; Šimek, Miloslav ; Picek, T. ; Grund, M. ; Šetlík, J.
Results on the evaluation of chemical and biological properties of soil affected by long-term acidification are summarized. It is shown that mountain ecosystems differ in their ability to adsorb nutrients and in the rate of nutrient leaching.
Degradation of soil by cattle on so-called winter pasture and its influence on nitrous oxide emissions
Šimek, Miloslav ; Brůček, Petr ; Uhlířová, Eva ; Šantrůčková, Hana ; Elhottová, Dana ; Kamír, V.
Results on the measurements of nitrous oxide emissions from cattle overwintering area located in South Bohemia are summarized. It is shown that the site investigated represents an important source of greenhouse gases including nitrous oxide and carbon dioxide. Long-term presence of animals led to changes in soil microbial community too.
Are the characteristics of microbial community proper indicators of soil quality?
Šimek, Miloslav ; Šantrůčková, Hana
Soil is a dynamic, living, natural body that is vital for terrestrial ecosystems. It has many ecological and human-linked functions. Definitions of important soil attributes - soil quality and health - is reviewed. Several aspects concerning soil quality assessment that are analysed in detail include requirements on indicators of soil quality and health and use of characteristics of soil microbial community for soil quality and health estimations. Possibilities for using microbial biomass as one of soil quality and health indicators are discussed.
