“…For the LT2 grassland we have to register a high AGB yield to be attributed to the presence of tall species like Dactylis glomerata L., Festuca arundinacea Schreb., Avenula pubescens Huds., Festuca rubra L. and Arrhenatherum elatius L. All these species prove that this grassland was more anthropized than the less productive grasslands. Similarly, an increase in the cover of tall species like Festuca rubra L. in abandoned mountain grasslands has been found by several authors (Pavlů et al 2012;Pavlů et al 2013;Pavlů et al 2016). Mašková et al (2009) also reported higher AGB yield in unmanaged fallow treatment compared to a mown mountain meadow.…”

This paper aimed to monitory the dry matter biomass production and carbon stocks of above-and below-ground biomass in five types of grasslands in Slovakia: i) lowland oversowed pasture ii) lowland hay meadows, iii) mesophilous pasture, iv) mountain hay meadows, v) abandoned grassland. Averaged over two cropping seasons the total above-and below-ground biomass differed significantly across the monitored grasslands. It ranged respectively from 2.18 to 7.86 t/ha and from 9.64 to 22.67 t/ha dry matter depending on the pedoclimatic condition and the botanical composition of each grassland type. Consequently, this resulted also in the carbon stocks in above-and below-ground biomass. Generally, the mean carbon stocks were 1.56 t/ha for above-ground biomass (24%) and 4.83 t/ha for below-ground biomass (76%). The botanical composition for all the grassland types was also described. The highest number of plant species (55) was observed in lowland hay meadow located in Slovak Karst, the lowest one (23) for the oversowed grassland located in Eastern Slovak Upland. This monitoring paper showed that semi-natural grassland habitats and improved grasslands as well are an important carbon sink, and they can play a key role in global climate change mitigation.

“…The issue of changes in grassland soils has been widely studied, particularly regarding the impact of grazing intensity and fertilisation on nutrient cycling [ 20 ], as well as the effect of different mowing regimes on soil physico-chemical properties [ 2 ]. Long-term mowing is often expected to decrease the availability of nutrients in the soil, particularly potassium [ 21 ], nitrogen and phosphorus [ 22 , 23 ], owing to the export of nutrients with the harvested biomass. On the other hand, nutrient impoverishment in grassland soils due to biomass extraction has not been found by other researchers [ 24 ].…”

The effect of abandonment on vegetation composition and soil properties in Molinion meadows (SW Poland)

Intermittently wet meadows of the Molinion alliance, as with many other grasslands of high-nature value, have become increasingly exposed to abandonment due to their low economic value. The potential consequences of land abandonment are the decrease in species diversity and environmental alterations. The issue of land-use induced changes in plant species composition and soil physico-chemical parameters have been rarely studied in species-rich intermittently wet grasslands. In this study we attempt to i) to identify determinants of plant species composition patterns and ii) to investigate the effect of cessation of mowing on vegetation composition and soil properties. The study was conducted in an area of 36 ha covered with Molinion meadows, comprising of mown sites and sites that were left unmown for 10 years. In total, 120 and 80 vegetation plots were sampled from mown and unmown sites, respectively. In these plots we measured plant community composition and soil physico-chemical parameters. The results have shown that the two groups of variables (soil properties and management) differ considerably in their ability to explain variation in plant species data. Soil variables explained four-fold more variation in plant species composition than management did. The content of soil organic matter, moisture, total nitrogen and exchangeable forms of potassium, calcium and magnesium were significantly higher in mown than in unmown grassland systems. The results revealed that soil organic matter was the component of the soil most strongly affected by management, followed by moisture, magnesium, calcium and potassium in that order. Each of these soil parameters was negatively correlated with the abundances of woody plants and invasive species. We concluded that low-intensity, late time of mowing is suitable grassland management practice to ensure high plant species diversity and sustainability of the grassland ecological system while cessation of mowing not only lead to reduced plant species richness and diversity, but also to reduced nutrient levels in grassland soils.

“…Honsová et al (2007) obtained similar grassland yield in a fertilized two-cut alluvial meadow (6.5 t/ha for N treatment, 4.5 t/ha for PK and control treatment per year 2005) as in this study, but they obtained significantly lower values of CH (also measured by RPM), which ranged from 5 to 21 cm. Pavlů et al (2013) measured the average range of CH from 10 to 30 cm with DMY 1.5 to 4 t/ha on the extensive mountain meadows. The differences between our results and the results of Honsová et al (2007) were caused mainly by the date of measuring CH and DMY characteristics; on the other hand the differences of Pavlů et al (2013) were caused by different dominant functional plant groups.…”

“…Hejcman et al (2007) described CH and plant composition in six fertilized and unfertilized treatments in low mesophilic meadows. Only Pavlů et al (2013) compared CH and the DMY in cut and unmanaged mountain hay meadows. They found a significant correlation (r = 0.53) between DMY and CH over seven years in a cutting treatment (one cut per year in mid-July) and an unmanaged treatment (unmanaged grassland) in a mountain hay meadow (Polygono-Trisetion alliance).…”

Monitoring of grassland dry matter yield (DMY) is important for the economy and ecosystem management, but it is a time-consuming process. Calculating the correlation between compressed height (CH) and DMY is a faster way to estimate DMY. The aim of our study was to use CH in order to predict DMY for a meadow with different fertilization management and plant species composition. Four fertilization treatments and one unfertilized control were established in a mesophilic meadow in the Czech Republic. Using a rising plate meter (RPM), CH was measured before the first and second cuts. In addition, the cover of individual vascular plant species was estimated. Significant correlations between CH and DMY were ranging from 0.41 to 0.79 for treatments without nitrogen fertilization in the first and second cuts; for treatments with nitrogen fertilization there was a significant correlation only in the second cut. According to our results, the RPM method seems to be suitable for a rough DMY estimate for meadows with coverage of about 60% grasses, 10% legumes and 30% forbs. However, considerable changes in the cover of tall forbs (e.g. Urtica dioica L.) or tall grasses (e.g. Dactylis glomerata L.) could be the main sources of DMY estimation inaccuracy.
