Název v původním jazyce
The species composition of an alluvial meadow after 40 years of applying nitrogen, phospohorus and potassium fertilizer
Popis výsledku v původním jazyce
In 1966, the Černíkovice experiment was started when an alluvial meadow dominated by Alopecurus pratensis was subjected to the following fertilizer treatments: non-fertilized control, PK, N50PK, N100PK, N150PK, and N200PK. The experimental plots were cutthree times per year in the initial phase of the experiment and twice per year since the late 1980s. In mid May 2005, plant cover was visually estimated, biomass yield and sward height measured in order to detect changes in the grassland ecosystem caused by this long-term fertilizer treatment. After 40 years treatment was a significant predictor of sward structure, explaining 32% of the variability in plant cover data in RDA. Legumes were not detected in the N200PK treatment and achieved the highest cover in the control and PK treatment. Grasses had the lowest cover in the PK treatment and control, which significantly differed from all treatments with N. Alopecurus pratensis prevailed in all NxPK treatments.
