    So far, Phragmites australis was omitted in exploration of chlorophyll dyes content in grasses. Elimination of this gap was the aim of this research. Works was carried out during growing season in 2013. Object of the research was reed from 8 reservoirs, in different sizes, located in western part of Poland. Plants were overgrown periphery of water basins, along the shoreline, and communities can be classified as Phragmitetum australis. Studies consisted of systematic, during the growing season – monthly, analysis of chlorophyll dyes presence in leaf blades. Obtained results bring significant value in biological characteristics of this species

    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 2012–2014 at the Experimental Station of Department of Grassland Natural Landscape Sciences in Brody University of Life Sciences in Poznań. 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–1
