Soil-water practice is essential for farm sustainability, thereby establishing the reference level for agricultural policy of the European Union (EU). This paper focuses on the critical gap in the knowledge surrounding comparison of soil-water effects of Good Agricultural and Environmental Conditions (GAEC) and carbon farming. We aim to interrogate...

The paper proposes a new soil evaluation system using the principle of the Saaty method. The Saaty method has been modified and named Soil Assessment System (SAS). Significance weights are assigned to individual soil characteristics (indicators). This provides a more detailed differentiation of the significance of the indicator on soil quality and...

Building on the agri-environment framework in Central and Eastern Europe, the article emphasizes the role and the use of the agri-environment in provision of different ecosystem services. It shows that relevant conservation measures with regard to ameliorating soil degradation contribute to the existence of sustainable land systems. In our study, w...

More than 50% of agricultural land is threatened by water erosion in the Czech Republic. With respect to soil erosion, maize (Zea mays L.) belongs to the most problematic crops; one of the possibilities to increase protection against erosion is intercropping. In this study, we attempted to find out the effects of individual intercrops and their mix...

The environment is changing quickly and it is ever more burdened in connection with the greater needs of human society. This fact has increased efforts to improve the management of land and natural resources and the necessity to evaluate them. Land valuations become more important as the land consumption increases. Soil needs to be evaluated in the...

The project dealt with an evaluation of the soil quality in the Central Bohemian Region in the Czech Republic. The relevant attributes and characteristics were found regarding the soils in this selected area. Based on the data from soil probes, climate characteristics, soil production function and data on the land use, the characteristics, known as...

Currently, due to the calamity of unplanned harvesting, the amount of biomass from wood products has increased. Forests occupy 33.7% of the total area of the Czech Republic; therefore, wood and non-wood forest products are important renewables for the country. Wood biomass consists mainly of branches and bark that are not used in the wood or furnit...

This study aims to evaluate the water balance of the crop mix of the Czech Republic and the tendencies of its development during the period 1961–2019. For calculating water deficits, methodology from ČSN 750434 (Czech technical standards) was used and on its basis, the deficits of the ten most frequently represented crops of the Czech Republic were...

Tile drainage belongs to the most important meliorative measures in the Czech Republic. It is hypothesized it may improve some properties of soils which are influenced by groundwater and their water regime. In the case of meadows, the used management method may also influence soil properties. In this study, different physical soil properties (parti...

Afforestation of less productive, risk and degraded agricultural land is one of the methods which are recommended for practical agriculture to increase carbon sequestration. In this study, we have attempted to determine the effect of afforestation of agricultural land (warm, mildly dry climatic region of the Czech Republic) on soil organic carbon (...

Currently, we can see a rapid decline of agricultural land with new uses, especially for construction purposes. This negative trend is evident across Europe, the Czech Republic has the fastest loss of land in the EU. One reason for the significant loss of agricultural land is building industrial zones, which utilises of greenfield areas, and their...

This paper sets out to clarify the factors in soil erosion and soil conservation. The Czech Republic struggles with soil conservation. Shifts in the rural economy, the loss of good-quality agricultural soil to urbanisation, and sub-optimal land management leading to erosion are at issue. Here, we apply quantitative and qualitative methods to assess...

The study presents an estimate of how many hectares of soil will be removed from the farmland fund in the coming years around the biggest towns for non-agricultural use, such as for residential purposes and industrial zones. To estimate suburban area spreading, so called "buffers", i.e. packing zones around towns, were established. For the capital...

The agricultural land acreage in Central Europe, including the Czech Republic, rapidly decreases. This study presents the trends of agricultural land acreage reduction in the period 1966-2013, with respect to the 1990 milestone (political changes triggering a rapid loss of agricultural land for construction purposes). The analysis is based on the c...

The land degraded by industrial activity or natural elements is uninteresting for investors; consequently, there have been no studies on the economic value of such land, in spite of its increasing amount. Methodologies exist assessing construction and agricultural lands but these methods are not adequate for the assessment of the degraded land. Thi...

Industrial activities in the Czech Republic have brought into existence many degraded and contaminated sites. Such areas are not suitable for farming, building or recreation purposes. The necessary reclamation is typically very expansive. In this study, the contingent valuation method (CVM) was used to estimate the public's willingness to pay for s...

Soil can be considered as a very important “ecological crossroad” in the landscape. From this point of view adequate attention has not been paid to it in our country during the last 40 years. Soil was mainly considered as a source for yields of agricultural crops and as a sink for placing different wastes. On the other hand, we meet many very biase...
