“…On average, the pig slurry is twice as rich in the content of phosphorous as the cattle slurry (Regulation No. 274/1998 of the Ministry of Agriculture), whereas phosphorus has a positive influence on legumes dominance in grasslands as it was proved by studies such as Skládanka and Hrabě (2008), Veselá et al (2009) or Raus et al (2012).…”

The aim of this study was to assess the effects of organicfertilizers (cow manure + dung water; cattle slurry) applied in different annual doses of nitrogen (54, 84 and 120 kg/ha) by different intensities of grassland utilization (extensive – two cuts per year, medium intensive – three cuts per year, intensive – four cuts per year) on percentage of plant functional groups, dry matter yield, and forage quality. The study was performed on small-plot trial over 7 years on moderately moist grassland in the Czech Republic. The proportion of legumes was significantly higher in the treatments fertilized with cow manure + dung-water combined with medium intensive utilization and intensive utilization (10.2% and 10.3%, respectively). Fertilization significantly increased dry matter yields by 51.9% (cow manure + dung water) and 56% (cattle slurry) compared with unfertilized controls (4.81 t/ha). Grasslands fertilized with cattle slurry showed significantly higher concentration of crude protein (142.9 g/kg) compared with unfertilized (126.4 g/kg). Extensive grassland utilization significantly affected the increase of crude fibre concentration (up to 282.1 g/kg), and decrease of the energy value (up to 4.68 MJ g/kg of NEL). Organic matter digestibility was also negatively influenced by extensive grassland utilization (61.0%, 65.42% and 67.44% for the extensive, medium intensive and intensive utilization, respectively). Our findings suggested that medium intensive and intensive grassland utilization by the organic fertilization, which corresponded to annual doses of nitrogen of 84 and 120 kg/ha were the most suitable from the viewpoint of animal nutrition.

“…Extensive harvest pattern supports the dominance of valuable species, yet at the same time the herbage is harvested too late in its inappropriate phenological phase. Raus et al (2012) reported that higher number of mowings per year caused expansion of grasses at the expense of non-leguminous forbs which are generally found less valuable. There were also detected some shi s within the group of grasses.…”

Abstract) were combined with four treatments of exploitation intensity (4 cuts per year, fi rst cut on 15 th May, every next a er 45 days; 3 cuts per year, fi rst cut on 30 th May, every next a er 60 days; 2 cuts per year, fi rst cut on 15 th June, next a er 90 days; 2 cuts per year, fi rst cut on 30 th June, next a er 90 days). Numbers of species, Simpson's diversity index and evaluation of grassland quality according to Novák (2004) were evaluated. Numbers of species and Simpson's diversity index were signifi cantly aff ected by both fertilization level and cutting pattern. Species richness decreased along with increasing fertilization rates from 29.4 (no fertilization) to 27.8 (N180PK). When comparing cutting pattern treatments the highest species richness was found in four-cut swards (29.6 in average of fertilization levels) and it declines towards late double-cut regime (27.2). The Simpson's index generally increased from two-cut swards to four-cut and from fertilized treatments to control. Grassland quality was signifi cantly aff ected by cutting pattern. Values increased from four-cut swards (38.1) to two-cut ones (43.8 and 44.0 in early and late harvest respectively).

“…In contrast, [19] found that the percentage of legumes in grassland increased with greater application rate of swine slurry. The reason for this finding could be that pig slurry supplies more phosphorus has a positive effect on legume dominance in grasslands as has been reported by [20,21,22].…”

The aim of this study was to assess the effects of organic fertilisers (cow manure + dung water; cattle slurry) applied in different annual doses of nitrogen (54 kg ha-1; 84 kg ha-1; 120 kg ha-1) according to 3 different intensities of grassland utilisation (extensive – 2 cuts per year, medium intensive – 3 cuts per year, intensive – 4 cuts per year) on percentage of plant functional groups (grasses, legumes, forbs), dry matter yield, and forage quality. The study was performed as a small-plot trial over 7 years on moderately moist grassland in the Czech Republic. The proportion of legumes was significantly higher in the fertilisation treatments with cow manure + dung-water combined with medium intensive utilisation and intensive utilisation (10.2% and 10.3%, respectively). Fertilisation significantly increased dry matter yields by 51.9 % (cow manure + dung water) and 56% (cattle slurry) compared to unfertilised controls (4.81 t ha-1). Grasslands fertilised with cattle slurry showed significantly higher concentration of crude protein (142.9 g kg-1) than unfertilised (126.4 g kg-1). Extensive grassland utilisation significantly increased crude fibre concentration (up to 282.1 g kg-1), and decreased the energy value (up to 4.68 MJ kg-1 of NEL). Organic matter digestibility was negatively influenced by extensive grassland utilisation (61.0%, 65.42 % and 67.44% for the extensive, medium intensive and intensive utilisation, respectively). Our findings suggest that medium intensive and intensive grassland utilisation using organic fertilisation which correspond to annual doses of nitrogen of 84 kg ha-1 and 120 kg ha-1, are the most suitable for animal nutrition.
