  Concerning the nutrient supply, it was found that the highest crop was produced with the N80K0 treatment (81.38 g m^-2). The K application resulted in a decrease in crop yield. The highest crop yield per plant was found in plots with 48 cm row space. The best germination was reached in the plots with 48 cm row space (73%).
  If the level of K was elevated, the essential oil content increased. The maximum essential oil content was reached by treatment N0K80 (2.6284 ml 100 g sza.^-1). The composition of essential oil was influenced both by the nutrient supply and by the growing area. Increasing the row space the ratio of d-carvone decreased. The amount of d-carvone was uniquely increased by use of K. The highest carvone level (66.25%) was identified at the N80+70K80 treatment as an average of row spaces.

  Red oak (Quercus rubra L.) is our most important exotic oak species, that possesses growing culture with almost one hundred years in our country. Plantation character of red oak growing predominates principally by applied regeneration method (mostly artificial), regular planting space, applying defined method and planting space regulation system. Forest tending model for red oak, that considered stopgap in the native literature is intended to serving the latter. Especially important equation in the viewpoint of stand growing, that describes relationship of stem number (N, in hectare) and diameter at breast height (D1.3 in cm) is: N=e9.80220-1.12607lnD1.3.

  The hinge of the lupine crop cultivation technology is the sowing time and the determination of the breeding area. According to the literature the early sowing (as soon as possible to go to the soil) and larger growing area is recommended for seed production. Based on the results of our 2 years experiment, the effect of sowing time and different spacing is important on yield of white lupine, and the effect of the sowing time is more significant. A decrease in the yield was observed after later sowings. The yield and the rate of its decreasing was varied in one year and among different years depending on wheather condition and sowing time.

  The role of sowing time is significant for protein content of seeds. The average protein content decreased due to the later sowings in 2014, while 2015 the protein content of seeds in early sowing time and of plants sowed 4 weeks later was similar. We measured less protein content in the 2. sowing time sowed 2 weeks later than the first one. In the studied years the average protein content of seeds from different row spaces were not different.

  We can get information about water conditions of plane areas by analyzing their relief. By using the Digital Elevation Model, we can get proper information about runoff conditions in the terrain surface, which is the basis for ponding analysis. In our study, a Digital Elevation Model of the sample plot in Hajdúsági-löszhát (loess ridge) was created that makes possible the determination of runoff conditions of the surface. Convergence and divergence of runoff direction showed the rate of ponding and the location of possible inland-water spots. By using this model, concrete location of those areas that tend to be overmoistured could be determined. Knowledge of this phenomenon can be an effective instrument for farmers in optimizing crop growing, and additionally in performing water management interventions in proper time and space.

  The main reason to analyzing the space structure in the Lublin area is to determine the direction and pace of suburbanization in municipalities adjacent to Lublin, distinction factors and motives of population movements to the suburbs, complain rural-urban interaction and multifunctionality of land use. Housing development over the years was accompanied by confusion in planning documents and the law. Changes in regulations on land use in 1994 and 2003 in Poland additionally deepened the negative situation. Local authorities failed to control the spontaneous process of suburbanization, which adversely affected not only the spatial structure of municipalities, but also on local relationship, landscape, land use and the former urban systems. The result are long-term problems associated with incompatibility rural areas to support a growing number of residents, such as failure of the social and technical infrastructure.

  Recent years have seen an increasing emphasis on child-friendly concepts in landscape architecture and urban planning, as well as a growing emphasis on school grounds and environmental education, both in terms of pedagogy and landscape design. School grounds provide places for active engagement with the environment, for experiencing what is taught in class, and, are therefore of particular importance for education and for building children's connection with nature. The aim of this research is to develop a set of landscape architecture tools that can be used to promote child-friendly and education-centered design of school grounds. The research collects and organises the different school ground features, drawing on literature research, and the analysis of the Framework Curriculum. The toolkit presented in this paper lists and evaluates each feature according to its function, its relevance to school subjects and the specific knowledge or skills it can help to acquire, its space requirements and feasibility. To conclude, school grounds offer opportunities for teaching almost any subject and can therefore be linked to educational activities in multiple ways. The results of this research are to be developed into design guidelines in order to be used by designers and teachers alike, to help develop school grounds contributing to the well-being and environmental awareness of new generations.
