The objective of this task is the assessment of carbon exchange in grassland areas using in-situ and remote sensing data. Grasslands are very sensitive ecosystem where significant changes of the carbon balance occur under different climate change, where grasslands either sequestrate or become the sources of carbon. The study was conducted in the years 2014\u20132015 at Wielkopolska Region, Biebrza River Valley, and Pieniny Mountains test sites, that cover three following grassland types: lowland non\u2013valley, lowland valley, and mountainous. The paper presents in-situ and microwave and optical satellite observations to quantify relationships between soil-vegetation parameters that influence spatial and temporal variability of carbon fluxes over these areas. The next step of the study is the application of satellite data acquired in optical and microwave spectrum to develop method for the assessment of carbon fluxes.<\/span><\/td>\r\n

These communities are of varied nature value and form valuable ecosystems of high landscape value. Their development, floristic diversity, nature and agricultural value are connected primarily with their moisture content, resulting from the habitat mosaic and land use intensity. The calculated floristic diversity index (H\u2019) ranged from 1.2 to 2.7, while valuation results provided by the method proposed by O\u015bwit showed that communities with moderately high and high nature value predominate in the area. Most examined communities are of poor and mediocre economic and utility value, as evidenced by the calculated fodder value score FVS=1.7\u20134.1.<\/span><\/td>\r\n

Funkcje trwa\u0142ych u\u017cytk\u00f3w zielonych na obszarach g\u00f3rskich w\u00a0kontek\u015bcie zmian prawno-gospodarczych
<\/strong><\/span>The role of permanent grasslands in mountain areas in terms of legal and economic changes<\/span><\/span><\/p>\r\nAbstract.<\/strong> Permanent grasslands in addition to the production role are also of ecological and aesthetic importance. After 1989, the socio-economic transformations that began in Poland have significantly affected the changes in agricultural use. There was a limitation of agricultural production and transformation of agriculture in the mountains into more ecological and sustainable one. The area of arable land decreased for the sodded areas. Some of the grasslands began to transform into areas used for non-agricultural purposes, and even for development. These changes also arise from legal and financial conditions. Pre-accession funds (PHARE, SAPARD), the Code of Good Agricultural Practice, as well as PROW 2004-2006 and 2007-2013 had already the impact on the permanent grassland changes. The current PROW 2014-2020 and the principle of \u201ccross-compliance\u201d also draw attention to the need to maintain and enlarge the area of the grasslands. These conditions meant that many sward areas are used only for the purpose of obtaining direct payments, but it\u2019s often forced farmers to change the way of grassland use. Many of them now have recreational functions. They are used to form golf courses, ski lifts, slopes for roller skis or horse-riding. The disadvantage of these changes is disorder of phenological phases of vegetation, or even destroying the sward. However, alternative use of green areas with proper care and preservation of the principles of sustainable development gives a chance for economic development of the region and indirectly reduces the total degradation of the grassland by e.g. self-forestation.<\/span><\/td>\r\n

The xerothermic grasslands under study are threatened by the lack of grazing, biocenotic evolution and accumulation of dead organic matter, which leads to succession changes in the natural habitat (secondary succession). The cutting of shrubs improved the shrub and tree-understory expansion index but brought only short-term results. The pasturage led to the improvement of parameters such as native expansive species of herbaceous plants, shrub and tree-understory expansion, and dead organic matter, which creates good conditions for the generative reproduction of xerothermic plants such as <\/span>Carlina onopordifolia<\/span><\/em>.<\/span><\/span><\/span><\/td>\r\n

<\/strong><\/span>The influence of pastoral activities in the Carpathian Mountains on floristic composition of pastures<\/span><\/p>\r\nAbstract.<\/strong> Since the 70s of 20th century the IT-P Research Station at Jaworki carried out works aimed at environmentally friendly utilisation of mountain pastures used for grazing large herds of livestock, especially sheep. Tasks were implemented under conditions of strict production research, taking into account various organizational and economical aspects. One of them was progressively restrictive use of expensive mineral fertilizers, and instead a careful spreading of manure on the surface of pastures. Depending on the floristic composition of sward, there was determined sheep population in the pen, where animals spent their nights. The enclosure was systematically transferred. At the same time the stocking density also gradually increased. Yielding changes of pasture sward were expressed as mean of individual, so called, penning rotations, which varied from 6 to 3 grazing seasons. The floristic composition of sward in selected years are presented, taking into account two altitude zones of pastures above sea level and the division into groups of vegetation. The variability of sward quality is rated by means of Utility Value Number (UVN). Basing on years of research it can be concluded that low cost pasture management in mountain areas can be both economically and ecologically proved.<\/span><\/td>\r\n

<\/strong><\/span>The effect of different doses of Soleflor soil improver and mineral fertilizers on botanical composition and yielding of grass-legume sward<\/span><\/p>\r\n Abstract.<\/strong> The aim of this study was to determine the effect of soil improver Soleflor used in sowing mixture of grass-legumes Country 2006 DSV on botanical composition of the sward, leaf greenness index of white clover and yields. Research on the effects of different doses and frequency of application Soleflor soil conditioner and phosphorus-potassium fertilizers was conducted in 2012\u20132014 at the Experimental Station of Department of Grassland Natural Landscape Sciences in Brody University of Life Sciences in Pozna\u0144. The use of soil conditioner Soleflor increased on the share in the sward of perennial ryegrass and tall fescue. A soil improver influenced on the higher percentage and durability of timothy grass and white clover in the sward. The highest SPAD index values in white clover leaf blades were found after the application along with a standard NPK fertilizer and soil conditioner Soleflor in doses of 400 and 600 kg ha\u20131<\/span><\/sup>.<\/span><\/span><\/td>\r\n
