Porovnání vlivu aplikace biologického odpadu ze zpracování Jatropha curcas L. a kompostu na vybrané půdní ukazatele a pěstovanou rostlinu
Foltýnová, Anna
This Master's thesis is focused on problems of modern agriculture. Current agriculture is facing many problems that already exceed the production area. Among these belong soil degradation caused by inappropriate agricultural practices, erosion phenomena, etc. Both developed and developing countries have experienced these problems. This soil degradation is mainly caused due to lack of soil organic matter content. Current agriculture therefore faces the issue of how to solve this problem. A simple solution is based on increasing the content of the soil organic matter in arable land. In the first part, this thesis describes various problems of modern agriculture and also suggests possible solutions. Regarding to content of soil organic matter, the thesis proposes solutions in the form of compost application into the soil. Besides compost, thesis presents an alternative organic fertilizer Jatropha seed cake. Jatropha seed cake is produced as waste after oil extraction from seeds of Jatropha curcas L. In the first part both of these substrates are further described, along with characterization of Jatropha curcas L. The aim of this thesis was to compare the fertilizing effects of Jatropha seed cake with compost. For this purpose, a pot experiment was conducted under controlled laboratory conditions. Application effect of Jatropha seed cake and compost on soil and plants was monitored at selected soil indicators. The results describe the impact of Jatropha seed cake and compost application on production of plant biomass, soil hydrophobicity rate, mineral nitrogen mobility and soil microbial activity.
