Abstract

fetched live from OpenAlex

Paludiculture, in the form of Sphagnum farming, is a renewable and cyclical way to produce Sphagnum moss fibres. The duration and frequency of water deficit due to the positioning of the water table level in the peat profile is a key driver for biomass accumulation rates in Sphagnum farming. For optimal outcomes, it is necessary to establish the threshold water table depth beyond which Sphagnum productivity decreases. In this article the daily water deficit (WD), the sum of daily water deficit (SWD) and the seasonal average water table ( ħ ) are examined to quantify water deficit. The compilation of data from five years of experimental Sphagnum farming, in both managed peatlands and greenhouse mesocosms, was used to build a dataset covering a wide variation of water table levels. This study strengthens the idea that the higher the water deficit, the lower the productivity of the Sphagnum species. Among the water deficit indicators analysed, WD and SWD have stronger correlation with Sphagnum productivity than ħ . The threshold water table depth determined for each subgenus is as follows: Acutifolia at 13.8 ± 1.9 cm, Sphagnum at 12.5 ± 1.4 cm, and Cuspidata at 3.1 ± 1.8 cm. These values correspond to a water table closer to the surface than reported in the literature for Sphagnum peatland recolonisation, which is 40 cm, and this is because the aim in Sphagnum farming is to maximise productivity.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
