Relationship between chemistry of surface water and geological environment in the forest catchment LIZ in the Šumava Mts
Škoda, S. ; Váchal, J. ; Dumbrovský, M. ; Tesař, Miroslav ; Váchalová, R.
More then 20 years the chemistry of surface water has been observed within GEOMON project in the Zdíkov region in the Šumava Mts. The knowledge of composition and chemistry of geological environment is very important for assessment of input and output of matter to/from this catchment. The geological underground has been make up of migmatitize biotitic and sillimanit-biotitic paragneises of Šumava Moldanubicum. Soils, represented by oligotrophic and oligomezotrophic cambisoils, are very acid, sorption unsaturated. Their silicate buffering system significantly contributes to decrease leaching of calcium, manganese, chlorine and total aluminum, and so to reduction of intensity weathering of rocks.

The Possibilities regional development of the marginal area Bohemia forest
Váchal, J. ; Pártlová, P. ; Váchalová, R. ; Koupilová, M. ; Moravcová, J. ; Krejča, M. ; Šír, Miloslav
Within the region of South Bohemia, 49.3 % of the total area is farmland utilized by agriculture; 60 % of this area belong to LFA category. The basic target of regional development is defined as sustainable development of the production and non-production functions of agriculture in compliance with social-economic aspects and the regional policy of the Czech Republic. The necessity to maintain agriculture in these areas is based on the principles of current European agricultural policy whose priorities are production methods aimed at preserving the environment and the landscape. Both foreign and our own experience indicates that the retreat of farming from the landscape means its gradual devastation affecting the natural, production, economic, architectural as well as social and cultural spheres, and, last but not least, the ecological situation.

Multifunctional agriculture – means to development of the non-production function in the landscape
Váchal, J. ; Pártlová, P. ; Váchalová, R. ; Koupilová, M. ; Moravcová, J. ; Krejča, M. ; Šír, Miloslav
The current position of the agricultural sector in the national-economic system does not correspond with the real needs of the modern society in the 21st century. This situation is felt in the most intensive way in the marginal fields, where further existence of agriculture is based on its coexistence with nature protection subject to economic interests, which are more important than the nature protection. Reasonable agricultural use of landscape on the basis of the multifunctional agriculture with parallel harmonisation of production and non-production functions can be very favourable for the landscape in many aspects. Economic effectiveness of this kind of system is negative and therefore it is necessary to support it by the State. Approaches of the society to this solution are primary and invincibly positive.
