“…Databases of economic, energy and environmental relations of crop production were used to evaluate the relations between tillage, climatic conditions, fertilization and chemical protection. The basis was a description of soil-climatic properties according to ESEU and monitoring of technological parameters in relation to the soil fertility in a comprehensive concept according to the crops production functions [31][32][33][34][35]. Basic information to the system ESEU was described in fundamental databases [36][37][38][39][40][41][42].…”

Fertilizer inputs, crop yields, the composition of technological operations and intensity of treatment with different types of pesticides in both basic approaches were evaluated. A comprehensive comparison of impacts showed that all crops, except sugar beet, achieved better economic and emission parameters of production based on the evaluation of GHG production by using reduced tillage compared to ploughing. The total reduction of GHG emissions based on CO2eq on average of all crops per ton as a result of the technological processes was 6% using reduced tillage. The most significant CO2eq reductions were achieved for rye and oat (13%), and spring barley (8%). The reduction of crop yields ranges from about 1% (spring barley) to 4% (grain maize). Cost reduction per tone was in the range of 14% (rye) to 2% (silage maize). The energy gain was at reduced tillage improved at poppy (8%), rape (4%), oat (3%), rye (3%) and spring and winter barley (2%). From the evaluation of the number of chemical protections, a lower number of total protections was found at the no-till system for most crops. In most cases, there was no difference between ploughing and reduced tillage. There was an increase in specific nitrogen consumption per tonne of production in marginal areas, reduced tillage led to an increase in soil compaction.

To analyse the potential changes in soil characteristics and associated impacts on the land price, the region of South Moravia was selected, strongly threatened by erosion and by claiming the most valuable land in suburban territories due to industrial and housing expansion. For the detailed analysis of the impacts of erosion and land appropriation in the region of South Moravia, the model territories of Brno surroundings with the municipality of Dolní Heršpice and Hustopeče surroundings with the municipality of Starovice were selected. The price of land degraded by potential erosion in the South Moravian region fluctuates between 88 and 2 400 EUR/ha. In the past 180 years, 148 ha of agricultural land in the total value of 822 815 EUR have been used for construction in the location under study in Dolní Heršpice. Further growth of the municipality should involve additional appropriation of agricultural land in the value of 411 000 EUR. In the studied land block of 100.5 ha, located in the Starovice municipality area, water erosion caused degradation in the total value of 92 000 EUR in the period 1978–2013. Extensive losses of fertile agricultural land are to be expected in the future. Their main causes are continuing land appropriation and degradation processes – soil erosion.

Agricultural Land Degradation in the Czech Republic

Soil degradation has been identified as a major threat to the productivity of agricultural land. In the Czech Republic, soils are threatened primarily by water and wind erosion, but compaction, loss of organic matter, loss of soil structure stability, pollution and over-fertilization, loss of biodiversity, and soil sealing are also major concerns. Poor soil health results in many off-site effects such as surface water siltation, groundwater pollution, loss of biodiversity in the countryside, and decreasing crop yields. The Czech agricultural landscape is characterized by large fields with a very small number of interrupting elements such as furrows, paths, or balks and the crop structure is rather uniform. The state has a history of land collectivization which first took place during the twentieth century. The ongoing intensive and unsustainable industrial farming, which is often focused more on high yields of certain economically valuable crops rather than the environment, speeds up soil degradation. These problems are fortunately recognized by the stakeholders, legal authorities, and the public. There has been significant debate on sustainable landscape management and agricultural practices, and many positive examples already exist in the Czech Republic.
