The article presents the results of a research on the occurrence and concentration of pesticides in the groundwater of the Dravsko polje aquifer in the period from 2013 to 2015. Based on the results, the evaluation of spatial distribution of pesticides in groundwater and the relation to land use was performed. In different hydrogeological periods, 76 groundwater samples were collected at 19 different locations. 15 pesticides with their metabolites in groundwater were identified. Despite the prohibition of use, atrazine and its degradation product desethylatrazine still remain the most commonly detected pesticides in groundwater. They are followed by metolachlor, desethylterbutylazine and terbutylazine. The pesticides alachlor, dimetamide, metazachlor and terbutrin were not detected. The analysis of detected pesticides by land use indicates higher values in areas with intensive agricultural activity. In the northern part of the Dravsko polje, where the city of Maribor is located, pesticide concentrations are lower. Increased pesticide values occur in the southern part of the Dravsko polje, which coincides with more intensive agricultural land use of the area. The coefficient of degradation product / primary pesticide ratio (DAR and DTA/ TBA) was used to estimate the "age" of contamination from atrazine and terbutilazine. Surprising is the high incidence of atrazine, which may result from old burdens, slow decomposition and hydrogeological conditions, or the use of atrazine after the enactment of the ban.

This article discusses the field of agricultural land protection against soil sealing in Slovenia from the perspective of the land development tax applied to land-use changes. In Slovenia, the land development tax for agricultural land use change was introduced in 1970s with the aim to slow-down the then huge interventions in agricultural land and at the same time to get financial resources for investments in agriculture, in particular for the purpose of agrarian operations. In the research, the methodology for calculating the land development tax for conversion of agricultural land to built-up land and the amount of the tax in Slovenia during reference intervals in the study period 1979-2012 is analysed. The results of the research are presented together with the legal framework, which regulated the discussed field in individual time periods. For the study period, an analysis of methodology for calculating the agricultural land development tax was done for three cadastral districts (Novo mesto, Kranjska Gora and Murska Sobota), and an in-depth analysis of actual payments was done in the area of administrative unit of Lendava in the cadastral district of Murska Sobota. It has been shown that the amount of the agricultural land development tax was changing in the study period and that its value in the past had significantly exceeded the amount, which was determined with the change of legislation in 2011, and has been even decreased in 2012.

The article presents the results of suitability analysis of land use records of agricultural and forest land from the Slovenian ministry responsible for agriculture, for the purpose of land use change monitoring in Slovenia. To date, these data are the only systematically gathered data concerning land use in the country. For qualitative land use change detection, the metadata of land use datasets are of crucial importance. In the article, the changing criteria for land use data acquisition of agricultural and forest land are exposed. For the case of the Pomurska Statistical Region, the analysis of land use change has been conducted based on land use data of the agricultural ministry in the period 2002-2011. The main objective has been to provide the basic information on the quality of used datasets in order to assist the critical and correct interpretation and use of land use data of the agricultural sector.

For the purpose of water management, the Water Act envisages the defining of water and waterside land data. The register of water and waterside land has not yet been established. Land use data is the first step to the final establishment of the register, as defined by the Water Act. In Slovenia, there are few registers containing data that can be interpreted as part of the water and waterside land in accordance with the act. A comparison of data from the land cadastre, the register of land use of agricultural and forest land and data obtained from tests of water and waterside land was made. We compared the definitions, methods of data capture, data quality and maintenance procedures, and performed visual and spatial comparisons of captured objects. The comparison included a general overview of the ownership of the areas where data from different registers overlap. In conclusion, the essential differences between the registers are presented together with proposals for harmonization of spatially dependent data from different registers. The focus is on proposals to create a single, uniform register of land use. [ABSTRACT FROM AUTHOR]

In the paper we present some illustrative examples from the Prekmurje region that are related to the issue of registration of water infrastructure in the land cadastre. The Prekmurje region is known among surveyors for the fact that it has a much higher geolocation quality of land cadastre in comparison with the rest of Slovenia. Surveyors are usually able to take this fact into account correctly in their work, but unfortunately this does not apply to other public services, which are responsible for specific areas of environmental management, such as water management and transport infrastructure management, records of agricultural actual use, etc. With the presented examples, we first show the damaging consequences of breaching the rules and facts of land cadastre in the management of water infrastructure facilities. Next, we present the beneficial consequences of compliance with land cadastre rules and facts in the case of extensive flow reconstruction of Kučnica stream on the state border with Austria and its recording in land cadastre. The main purpose of the presented cases is to help the competent managers of water infrastructure in Slovenia to understand better and adhere strictly to the fundamental role of land cadastre in the spatial management.
