Možnosti využití hnojení při zalesňování nelesních půd v PLO 31 Českomoravské mezihoří
 Dujka, Petr
An afforestation of agricultural lands in the Czech Republic has a long tradition. In the future, a few thousands of hectares of agricultural lands is considered to be afforested. The aim of this thesis is to research possibilities of fertilisation usage in process of agricultural lands afforestation within Natural forest area (NFA) 31 Českomoravské mezihoří. The research part of the thesis contains results of soil and nutrition analyses applied in Letovice-Kochov research area. The main goal of analyses was to find the impact of fertilisation on chemical soil characteristics, on nutrition of Norway spruce's needles (Picea abies (L.) Karsten), on the development of morphological quantity, and on the health of specimen. All of the characteristics are assessed in the context of climate in 2016. The positive effects of fertilisers were researched despite a low-humid year. The best effects were spotted at fertiliser SilvamixR30. To the results, SilvamixR30 fertilizer could be used in praxis, especially for agricultural lands afforested in named NFA.

Hodnocení ekologických limitů a zdravotního stavu jedle bělokoré (Abies alba) v oblasti Šumavy
 Kopa, Václav
White fir trees used to be the most abundant conifer of our forests. Today, however there is a minority of them. That is why I decided to elaborate the work that will deal with the white fir tree in different vegetation zones (VZ) of natural forest areas (NFA) of the Šumava mountains, Přehoří Šumavy and Novohradské hory. The lowest-lying mapped area was the locality close to Címice near Címický Lake at an altitude of 553 m in the 4th VZ. The highest location was the area near Horská Kvilda on the edge of Zhůřské peatbog in the 8th VZ at an altitude of 1144 m. The current health status of the white fir trees and the influence of biotic and abiotic factors on its life manifestations were evaluated. The most significant limiting factor is game.
