What Is the Effect of Long-Term Cutting versus Abandonment on the Vegetation and Chemical Properties in the Soil and the Herbage of a Mountain Hay Meadow (\u3cem\u3ePolygono-Trisetion\u3c/em\u3e)?

Polygono-Trisetion meadow communities are endangered in Europe. These meadows are common in the Alps, but in the past, such meadows were also common in the western alpine regions of Central Europe. The aim of our experiment was to find a suitable management regime for the maintenance of these Polygono-Trisetion grasslands and its effect on the vegetation and chemical properties of the soil and in the herbage

Extensive management of permanent grasslands by mulching in upland areas

This methodology includes the newest knowledge about impact of extensive management by mulching on structure and biodiversity of grasslands, management influence on the rate of aboveground plant biomass decomposition and biomass accumulation. This work summarises the results of long-term experiments with the different management treatments

Restoration management of cattle resting place in mountain grassland.

This study investigated the effect of restoration management of a weed-infested area, previously used as cattle resting place, on herbage production and nutrient concentrations in the soil and herbage. The experiment was undertaken from 2004 to 2011 at the National Park of Nízké Tatry, Slovakia. Three treatments were applied: (i) cutting twice per year, (ii) herbicide application, followed after three weeks by reseeding with a mixture of vascular plant species and then cut twice per year, and (iii) unmanaged. Treatments had significant effect on biomass production and concentration of nutrients in the soil and in herbage. Nutrient concentrations in herbage and in soil declined progressively under the cutting treatments and reached optimum ranges for dairy cattle at the end of the experiment when herbage N was less than 15 g kg-1 and herbage P was 3.4 g kg-1. There was also a strong positive relationship under the cutting treatments between soil nutrient concentrations and herbage nutrient concentrations for N, P, K, Mg and Ca. Although the cutting management as well as the combination of herbicide application with cutting management reduced nutrient concentrations in the soil and in herbage, the nutrient concentrations remained relatively high. We can conclude that restoration of grassland covered with weedy species like Urtica dioica and Rumex obtusifolius, with excessive levels of soil nutrients, cannot be achieved just by cutting and herbicide application

The effects of first defoliation and previous management intensity on forage quality of a semi-natural species-rich grassland.

Semi-natural grasslands occupy large parts of the European landscape but little information exists about seasonal variations in their nutritive value during the growing season. This paper presents results of novel data showing the effect of 13 years of previous contrasting management intensities on herbage nutritional value in relation to different dates of first defoliation (by grazing or haymaking). The treatments were: extensive management and intensive management from previous years (1998-2011). Both treatments were cut in June followed by intensive/extensive grazing for the rest of the grazing season (July-October). To evaluate forage quality in the first defoliation date, biomass sampling was performed in the year 2012 for 23 weeks from May to mid-October, and in 2013 for seven weeks from May to mid-June. Sampling was performed from plots that were not under management during the sampling year. Previous extensive management was associated with significantly reduced forage quality for in vitro organic matter digestibility (IVOMD), crude protein, neutral detergent fibre, acid detergent fibre and reduced divalent cations (Ca, Mg) and Na during the first seven weeks of the grazing season and the forage was suitable only for beef cattle. Due to low forage IVOMD, the forage is suitable only for cattle maintenance or for low quality hay when the start of grazing was postponed from seven weeks of vegetative growth to 13 weeks, regardless of the previous intensity. Herbage harvested after 13 weeks of the grazing season was of very low quality and was unsuitable as a forage for cattle when it was the only source of feed. Agri-environmental payments are necessary to help agricultural utilisation to maintain semi-natural grasslands by compensating for deterioration of forage quality, not only for the postponement of the first defoliation (either as cutting or grazing) after mid-June, but also when extensive management is required

Management of permanent grasslands in relation to agri-environmental measures:Questions and answers

This methodology simplified results from research project “Functional plant traits and their diversity as indicators of various permanent grassland management” for nature conservation authority. It is based on long term grassland experiments. There are important data for preparing of some agro-environmental provision in the practical part. This work summarises the results of long-term experiments with the different management treatments. It is intended especially for employers of administration of nature conservation, and also it can be used for students and pedagogues of secondary schools and universities concerning nature conservation
