Abstract
Grassland as a part of farmland is important for agrobiodiversity, soil protection and agricultural production (grazing, hay production). In the Czech Republic, grassland area increases with increasing altitude. In this study we evaluated the period 1966–2021 and the change in grassland area in different locations in South Bohemia region: fertile lowlands (PĂsek, ÄeskĂŠ BudÄjovice, TĂĄbor districts) and marginal uplands (ÄeskĂ˝ Krumlov, Prachatice districts). Data on land use including the share of grassland were obtained from the Czech Cadastral and Surveying Office and Czech Statistical Office. In the upland districts, there is the largest share of grassland areas in the whole region. The prevalence of grasslands is probably due to the geographic and climatic conditions, which are challenging here. Our research shows the results of changes in grassland areas between 1967 and 2021, with regard to the assessed districts. The difference in the percent area of grassland in 2021 compared to 1967 is –0.04 to –1.77 for lowlands, and +1.45 to +5.99 for uplands. Despite this, uplands farmers practice relatively extensive farming methods and extensive grazing due to low ruminant numbers. Although farmers maintain relevant carbon sinks, it is unlikely to increase the carbon stocks per hectare of extensive grasslands on an annual basis, which would be a barrier to participation in a carbon farming system.

An international peer-reviewed journal published under the auspices of the Czech Academy of Agricultural Sciences and financed by the Ministry of Agriculture of the Czech Republic. Published since 2006.
Thematic: original papers, short communications and critical reviews from all fields of science and engineering related to soil and water and their interactions in natural and man-modified landscapes, with a particular focus on agricultural land use. The fields encompassed include, but are not limited to, the basic and applied soil science, soil hydrology, irrigation and drainage of lands, hydrology, management and revitalisation of small water streams and small water reservoirs, including fishponds, soil erosion research and control, drought and flood control, wetland restoration and protection, surface and ground water protection in therms of their quantity and quality.
