Title: Economic assessment of degraded land
Abstract: 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. This paper introduces a new methodology to assess the land contaminated by heavy metals and regularly inundated. Simultaneously, this paper offers solutions of the best use of such degraded land.

Title: Optimisation of soil conservation systems within integrated territorial protection
Abstract: The objective of this contribution is to provide information on a generally applicable optimisation procedure intended for designing a system of terraces and retention reservoirs within integrated territory protection from the harmful effects of soil erosion. The formulated procedure is a universal tool which can be used for any territory. An optimisation mathematical model was used to find the most suitable combination of various elaborated pre-optimisation variants of the soil conservation and flood prevention measures under the given conditions of each particular habitat. This model was created on the basis of a mixed discrete programming. The model compilation and its analysis on a high performance computer was performed using the model and calculation system GAMS. The model solution was controlled by one or more simultaneously operating optimisation criteria. A system of terraces as an important part of the soil erosion and flood control was chosen to verify the possibilities of the described optimisation procedure utilisation. The system was proposed within the land consolidation in the case study areas of Hustopeče and Starovice cadastral areas. First, the model function and performance were verified. Then the possibilities of experimentation on the model of the solved system of complex conservation measures were tested. The main results of the real and some experimental solutions are summarised. The results of practical applications of the integrated territory protection model validate its functionality and universal applicability.

Title: An analysis of the Rendzina issue in the valid Czech soil classification system
Abstract: The article deals with the soil classification system valid in the Czech Republic. Using the soil type Rendzina from the former genetic-agronomic soil classification as an example, it analyses and revises the class definitions (soil types and subtypes), particularly their clarity, solidity, and mutual exclusivity based on the real state of diagnostic characteristics. The article advocates that the valid national soil classification system should be adequately detailed to satisfy practical needs and to preserve its convertibility into the international classification WRB system. At the same time, it should not be inconsistent with the methodology of the international project SOTER.
Keywords: soil classification, genetic-agronomic classification, TKSP CR, soil conversions, Rendzina

Title: Soil-terrain modelling and erosion analysis at field scale level, a case study
Abstract: Pedometrical methods and digital soil mapping represent a progressive approach to the evaluation of various terrain-related soil processes. A detailed digital terrain model was used for the analysis of erosion - sedimentation situation and description of specific soil properties at meso-relief scale. A study plot in Central Bohemia (area 4 ha) with highly diversified geological conditions was chosen for the study combining digital modelling with a detailed terrain survey and laboratory analysis. The curvature and topographic wetness index values were the main features for the accumulation and soil loss areas evaluation. The terrain survey and DTM results corresponded in the case of the soil cover structure and soil depth, showing a vast impact of accelerated water erosion and direct tillage erosion on the soil redistribution. In the concave and base slope positions, colluvial soils were identified, while Regosols with A-C profile stratigraphy form in the upper convex parts of the study plot. Particular soil properties distribution (pH, organic carbon content, texture) is, besides erosion, significantly influenced by parent rock variation and the relation to the terrain characteristics is less distinctive. The study showed a significant impact of the terrain properties on the general material redistribution and the possibility of soil cover structure prediction in areas with complicated geological conditions.
