Content of selected macroelements in the aerial and underground biomass of plants from old stands of the genus Miscanthus

Content and Uptake of Ash and Selected Nutrients (K, Ca, S) with Biomass of Miscanthus × giganteus Depending on Nitrogen Fertilization

“…In a 12-year study by Helios (2018) [46], the calcium content ranged from 3.1 g kg −1 DM while calcium uptake amounted to 0.45 g m −2 in the first year of experiment to 0.5 g kg −1 DM, while the calcium uptake was 1.2 g m −2 in the tenth year of cultivation. In studies by Baxter et al (2014) [15] and Stypczyńska et al (2017) [21], leaves of miscanthus were characterised by higher calcium content compared to the stems, which is confirmed by our research. In conducted experiments by Lewandowski and Kicherer [42], the calcium concentrations in the leaves ranged from 2.3 to 3.7 g kg DM while that in the stems ranged from 0.5 to 1.1 g kg DM.…”

“…Aerial parts of grasses accumulated mostly calcium, potassium and magnesium. The issue of calcium content in the rhizomes was undertaken by Stypczyńska et al (2017) [21]. The concentration of this element in their study in the rhizomes was 1.5 g kg −1 DM.…”

“…The content of elements in the biomass is significantly influenced by genetic properties [14,18] which can be modified by environmental conditions, such as soil properties, pH, weather conditions (precipitation, temperature), as well as agrotechnical treatments-mainly fertilisation [19][20][21][22][23]. Date of harvest (late winter or spring) can also contribute to the Agriculture 2021, 11, 76 2 of 16 reduced content of nutrients that results from their translocation from aboveground part of plant to rhizomes or natural leaching of components from leaves and stems [23][24][25].…”

Possibilities of Using Fodder Galega in the Energy Sector and Agriculture

“…In examining subsequent years of research, the highest percentage share of calcium, potassium, phosphorus and magnesium was found in the fourth year of research, and the highest share of sulphur and sodium was found in the fifth year. The results obtained were lower than those obtained in the research with other energy crops -miscanthus sinensis, virginia mallow, basket willow (Stolarski, 2008;Stypczyńska et al, 2017). The harvesting date of energy crops significantly affects the content of macroelements (in particular, of potassium) in biomass and ash.…”

“…The ash obtained from the combustion of fodder galega biomass, containing large amounts of alkaline elements, can be used for deacidification of medium and heavy soils (Regulation Commission UE, 2013). The possibility of using ashes to increase soil alkalinity, to improve the properties of heavy soils and to increase the content of macroelement in soils was indicated in the research by other authors (Kowalczyk, 2017; Stypczyńska et al, 2017;Symanowicz et al, 2018).…”
