Historical land use in Scandinavia and its influence on carbon storage in soil and peat in the boreal landscapeHahnwald, Sandra January 2015 (has links)
The history of land utilization in Scandinavia is characterized by two major periods of open landscape. The first one temporal ranged from cal. AD 0-500 and the second one ranged from cal. AD 1200-1900 including the medieval crisis in Scandinavia. Both periods were characterized by animal husbandry and intensive grazing as well as cultivation. However, slash-and-burn-cultivation and hay production on mires and meadows were prevailing during the medieval crisis. These activities significantly altered the concentration of transported organic carbon (OC) from the terrestrial ecosystem to inland waters. Burning and grazing decreased the terrestrial OC and water table, due to reduction of biomass, whereby burning has a greater effect. Biennial scything of mires for hay production reduced the biomass as well, hence resulting in a decreasing water table and peat accumulation. Even though two periods of open landscape has been present in the historical land utilization of Scandinavia, only the latest one resulted in a decreasing OC concentration in surface water in boreal lake. This indicates that especially the slash-and-burn cultivation and hay production on mires are very important components of altering the carbon storage in soils and peat due to lowering the terrestrial OC pool.

Analýza krmivové základny v Agro-B s.r.o., Kardašova Řečice a návrhy na její zlepšení / Analysis of fodder crop production in Agro B s.r.o., Kardašova Řečice and projects to it´s improvementPÍCHOVÁ, Ivana January 2007 (has links)
In the years 2005-2006 it was practised the analysis of plant production and the evaluation of typological structure of selected grasslands in selected farming business. It were evaluated the gualitative indices of produced roughage. It were evaluated the area sof annual crops, multi-annual fodder crops and of permanent grasslands and the produce of fodder of fodder crops and the sort and categories of stock cattle.
