“…The mineral value of forage in a meadow depends not only on the mineral content of each species, as conditioned by environmental and management factors [73], but also on the animal's needs for these elements and their real absorption capacity [4]. Taking as reference the nutrient requirements of beef cattle [42], and knowing that requirements vary according to the animal categories, the optimal and toxic values of the concentrations of the different elements (g kg −1 ) in the forage are: P (3.5; >10), K (11.5; >30), Mg (1.4; >4), Ca (6.5; >20), and Na (1.0; no toxic data).…”

“…P deficiency reduces growth and milk production and impairs reproduction [42]. P deficiency values in forage have been described in lowland semi-natural species-rich grasslands [23], in meadows from the order Arrhenatheretalia [73], in unfertilized mountain pastures [70], and in Pyrenean summer pastures [61]. In meadows with agricultural management that includes fertilization, P deficiency does not exist [59,74,75].…”

Nutritional Quality of Plant Species in Pyrenean Hay Meadows of High Diversity

2020

The feed quality of 34 species (27 dicotyledonous and 7 grasses) present in the vegetation of the Pyrenean mountain hay meadows rich in species subject to extensive management is analyzed in this paper. For this, just before mowing, samples were taken in the field and their organic and mineral components were determined in the laboratory. The results indicate that some species, such as Taraxacum officinale, Sanguisorba minor, Chaerophyllum aureum, and Lotus corniculatus, are outstanding in their forage feed value and, in the cases of T. officinale and C. aureum, also for their mineral content. The non-leguminous forbs studied presented quality comparable to legumes and higher than grasses, which provide worse nutritional values in this type of late-cut meadow. The forbs are shown to have higher content than grasses and legumes in Mg, K, and Na, as well as intermediate Ca content. All species present suitable mineral content for animal nutrition, except in the case of P, which is low. The Ca:P ratio is higher than adequate in half of the species analyzed, while the K:(Ca + Mg) ratio is appropriate for all species. The ratios between the elements N, P, and K indicate that most of the species studied grow under N-limited conditions, which are adequate for their conservation in the meadows.

“…By contrast, in extensively used meadows with a high nature conservation value and herb cover, the FUV is 6.8 with 60% of grass cover (Kryszak et al, 2010). A positive correlation between biomass production and the FUV has been found in Arrhenatheretum elatioris meadows, where semi‐natural grasslands with a grass cover of 50% could produce 300 g‐DM m −2 of biomass with an FUV of 5.7, whereas those with a grass cover of 80% could produce 500 g‐DM m −2 of biomass with an FUV of 7.0 (Wyłupek et al, 2014). The biomass productivity and the FUV can be increased easily through the application of fertilizer (Trąba & Wolański, 2001), which in turn boosts the cover of highly productive grasses with a high fodder value.…”

Restoration of ecologically valuable grassland on sites degraded by invasive Solidago: lessons from a 6‐year experiment

2022

Most semi‐natural grasslands are threatened by invasive alien plants, which have also overgrown abandoned fields. We conducted a 6‐year experiment testing different methods of eliminating invasive Solidago species and adding seed to restore valuable species‐rich grassland. Three removal treatments (herbicide spraying, rototilling, turf stripping) and two seed addition methods (direct sowing of a fast‐growing grass species mixture, spreading of fresh hay collected from a semi‐natural meadow) were examined alongside control treatments (no removal, no seed addition). The experimental plots were mowed twice a year, and the vegetation composition, biomass production, hay chemical composition, and fodder quality were assessed. Mowing twice a year significantly reduced Solidago cover. Although significant differences were observed in the invaders' cover between the removal treatments and between the seed addition methods early in the study, the differences lessened over time, especially for the removal treatments. By the end of the 6‐year study period, the Solidago cover was reduced to 25% of the initial complete coverage. Spreading fresh hay greatly reduced Solidago biomass and yielded the highest characteristic species cover. Herbicide treatment was no more efficient than the more environmentally friendly methods over the study period. The results suggest that fresh hay is good method of seed addition for restoring old fields overgrown by invasive Solidago. With mowing of the restored area twice a year for several years, Solidago removal by turf striping (scalping) followed by the spreading of fresh hay is recommended for grassland restoration given its environmental impact, cost, and hay quality.

Abstract. The aim of the study was to assess the influence of different fertilizer doses on the content of macroelements (nitrogen, phosphorus and potassium) in dry biomass and grain of maize during the 2016 – 2018 period. A field experiment with fertilization of maize was carried out on Alluvial-meadow soil (Fluvisol) in the region of Tsalapitsa village, near Plovdiv. Three variants of mineral fertilization were studied V2 (N15P10K0), V3 (N20P15K0) and V4 (N25P20K0), and a control variant V1 (N0P0K0) – without fertilization. It was established that N% content in maize dry biomass was affected significantly by the variants of fertilization (18% of the variance). Significant differences (P≤0.05) between the control variant and all the variants of fertilization were established. Increasing the fertilizer dose, nitrogen content in dry biomass increased, too. The highest was the average content of nitrogen in maize leaves (0.94%), followed by the cobs (0.71%) and the lowest was the content in the stems (0.58%). Phosphorus and potassium content of dry biomass were affected significantly by the year of the study (10% and 9% of the variance, respectively). At the 7-8th leaf growth stage of maize, the highest nutrients content (N, P, K) in dry biomass were reported. With aging of plants the nutrient content in their biomass decreased. Nitrogen, phosphorus and potassium content in maize grain was significantly affected by the year of the experiment. Mineral fertilization had impact mostly on the nitrogen content of the grain, which was the highest in V3 variant, accepted as optimal – 0.66% on average.
