ABIOTIC FACTORS OF SOIL’S RESPIRATION

The problem of interpretation the soil’s respiration data as quantitative characteristic of its biological activity and ecological gaseous function is investigated in laboratory and field experiments. Physical hydrotermical factors influence biogenic component of soil respiration as well as its abiotic compounds  (phased interaction, gaseous transport). Thus wide-spread pure biological interpretation of carbon dioxide emission from the soil is not correct and it often leads to wrong results and conclusions. Abiotic factors contribution to soil’s respiration is investigated at quantitative level with using original experiments connected with the problem of ecological evaluation gaseous function of soil as source, sink and reservoir of organic carbon in terms to atmosphere.

The concentration level of different heavy metals is analyzed at the distance of 0-5 and 5-20 cm in ordinary chernozem. Thus in soil samples from: 1) ploughed field after winter wheat harvesting; 2) woodland park at the beginning of leaf fall; 3) fallow land after ripening of Bermuda grass seeds. It has been shown that heavy metals and manganese behave differently in various agrolandscape compartments, according to the way of their utilization.

YAK GRAZING IN THE NORTH-WEST CAUCASUS: ECOLOGICAL CONSEQUENCES

V.G.Onipchenko, Z.S.Ezhelev

Открыть реферат статьи
 

Yak was introduced to alpine areas of the North Caucasus more than 30 years ago. Recent yak pastures were studied in Kendellesu valley, Karachai-Cherkessian Republik. Floristic richness of main alpine communities do not differ from correspondent communities in protected areas. Yaks disturb and destruct upper soil horizons on siltstones due to the low erosion persistence of the soils. We recommend forbidding yak grazing on alpine siltstone soils.
