Ekologická charakteristika organozemí a možnosti využití rašelin v oblasti vybraných ložisek Třeboňské pánve a Krušných hor
Janoušek, Josef
In the introduction part the dissertation is concerned with the state of peat harvesting in The Czech Republic and ecological characteristics of representative peat bogs in the Trebon area and Krusne Hory. The part methodology is based on selection of areas of research, description of initial and final state and establishing research areas in devastate areas of Krusne Hory. An important component of methodology was definition and development of substrate for re cultivation and monitoring of influence of applied substrate on the soil and seedlings. Experimental substrates were developed and manufactured in Raselina a.s. company. These substrates were applied together with experimental seedlings of Picea abies (L.) Karsten in research locations. Data were gain continuously for formulation of results, which were evaluated in graphs and statistics. From results follow that addition of well chosen organic matter on the base of peat or compost in the area of planting hole within planting of Picea abies (L.) Karsten and following application of substrate near to the trunk, in next years, can significantly optimized nutrition in the stand and ensure higher growth in first years, which are key for successful growth. The best results from the point of optimal nutrition in period of three years were achieved in the substrate EXPM2, which was formulated by compost and peat. The best growth between 2012 and 2014 occurred in substrate EXPM 1, which was made from peat and fertilizer Silvamix R with stimulator. Finally we can state that for complete dealing with this topic, and statements with more general validity, we would need more data from longer period, which exceeded possibilities of these theses.
