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. |
