Cropping of Miscanthus in Central Europe: biomass production and influence on nutrients and soil organic matter

Abstract

The objective of the present study was to investigate the impact of biomass development of Miscanthus x giganteus (Greef et Deu.) on the concentration of plant nutrients and the accumulation in soil as well as quality of soil organic matter (SOM). Field trials with 4-9 year-old Miscanthus stands were investigated and sampled at four experimental sites in Germany in the years 1994-1999. From 1994 to 1996 the above-ground standing biomass at the end of the vegetation periods ranged from 14.8 to 33.5 t ha(-1) dry matter (DM). The below-ground growing biomass (rhizomes, roots) reached 15 to 25 t DM ha(-1) (before sprouting in spring). Mean pre-harvest losses (harvesting date: February/March of the following year) of 4.5 t DM ha(-1) originated from senescent leaves and shoot-tips fallen to the ground during winter. This amount corresponds to about 26% of the whole above-ground biomass (harvested biomass + pre-harvest losses + harvested residues). Direct harvested residues (stubble mass) varied between 0.7 and 3.1 t DM ha(-1). Therefore 23-51% of the biomass grown could not be harvested. The mean harvested biomass was 11.7 t DM ha(-1). The largest concentrations of N, P, K and Mg in plant materials were observed in the pre-harvest losses, whereas the harvested biomass had the lowest concentrations. The concentration of nutrients in the harvested biomass was 61% (N), 64% (P), 55% (K) and 50% (Mg) of the concentration in the biomass at the end of the vegetation period. These differences are explained by nutrient losses due to fallen leaves and shoot-tips and nutrient translocation into below-ground plant parts. The higher concentrations of plant available K in soil indicate that Miscanthus cropping enhances the cycling of nutrients in the plant-soil system. As a result of the high input of leaves, rhizomes and roots, the sandy soils were characterized by increased concentration of organic carbon (C(org); mean: + 2.0 g kg(-1) and total nitrogen (N(t); mean: + 0.2 g kg(-1)). The storage of SOM in topsoils was increased by 11.7 t ha(-1). Moreover, the Miscanthus residues affected the quality of SOM. In a plot with Miscanthus, increased proportions of alkanes, alkenes, sterols and free fatty acids were observed by pyrolysis-field ionization mass spectrometry.

  • Miscanthus has the potential to sequester soil C.

    “Miscanthus has the potential to sequester soil C, and prior studies have reported that a considerable amount of miscanthus plant C was allocated to and accumulated in soil (Anderson- Teixeira etal.,2009; Hansen etal.,2004; Kahle et al., 2001; Mishra et al., 2013).”
  • Prior studies have reported that a considerable amount of miscanthus plant C was allocated to and accumulated in soil.

  • The tendency for land conversion loss followed by SOC accumulation under Miscanthus was not statistically significant because of one site where SOC was lost following establishment.

    “The tendency for there to be a land conversion loss followed by SOC accumulation was not statistically significant because of the effects of one site where SOC was lost following the establishment of Miscanthus (Kahle et al., 2001).”

  • SOC sequestration by the temperate perennial grasses (Miscanthus, switchgrass, and North American native mixtures) would augment the benefits of fossil fuel displacement.

    “SOC sequestration by the temperate perennial grasses (i.e., Miscanthus, switchgrass, and North American native mixtures), as observed here and else-where (e.g., Potter et al., 1999;Ma et al., 2000;Kahle et al., 2001;Lemus & Lal, 2005;Liebig et al., 2005Liebig et al., , 2008)), would augment the benefits of fossil fuel displacement.”

  • The increase in fine root biomass, at least for herbaceous perennial energy crops, is similar to that reported for a younger plantation by Kibet et al. (2015), but higher than that reported for plantations of a similar age.

    “The increase in the FRB, at least for herbaceous PECs, is similar to that reported for a younger plantation by Kibet et al. (2015), but higher than that reported for plantations of asimilar age (Christensen et al., 2016; Kahle et al., 2001; Richter et al., 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
