Vliv hnojení na mikrobiální a chemické parametry půd vyvijejících se na Krušnohorských výsypkách. / Th effect of fertilization oan microbial and chemical soil properties in post mining sites.

Hermová, Markéta January 2013 (has links)
The effects of fertiliser application, recultivation type and site age on chemical and microbiological soil properties were examined on a short-term (1year) experimental trial situated on spoil heaps in Sokolov mining district, Czech Republic. Treatments at the site included fertilisation by inorganic form of nitrogen, concretely calcic saltpetre (N) and fertilisation by inorganic form of phosphorus, namely superphosphate (P). Plots were either fertilised in the beginning of growing season or unfertilised. Microbial biomass-C increased as a consequence of both N and P addition while comparing with control. There was a significant effect of fertilisation on non-fumigated C representing labile source of carbon. With N,P application non-fumigated C significantly decreased. Specific respiration rate calculated as basal microbial respiration to microbial biomass-C was significantly increased by fertiliser application. In contrary, no significant treatment effect on the other parameters include water extractable carbon, total C, total N, available P, soil pH and basal respiration was recorded. The results indicate that short-term fertilisation is not able maintain soil condition. Therefore, site age or recultivation treatment had significant effect on mostly investigated parameters (WEC, total C) rather...

Ochrana dřevin proti štítenkám v ekologické a integrované produkci

Jégrová, Kateřina January 2014 (has links)
The research was realized during the growing season in 2013 in an apple orchard of the cultivar Golden Delicious near the village Nosislav (district Břeclav, elevation 170m). The efficiency of four products against San José Scale (Quadraspidiotus perniciosus) was investigated. The first adult San José Scale males were found in pheromone traps on the 28th of May. Occurrences of the first and second generation of the first instar nymphs (crawlers) were calculated according to effective temperatures sum to be on the 20th of June and 6th of August. The highest efficiency against San José Scale (59.6 to 60.9%) was found in a product based on Beauveria bassiana. The efficiency of a product based on the oil of Pongamia pinnata was between 41.8 and 56.9%. The efficiency of a product based on orange oil was lower, between 32.8 and 39.6%. The lowest efficiency, only 17%, was detected in a product with the active substance spinosad.
