Abstract

fetched live from OpenAlex

A developing bioeconomy and the need for alternate sources of energy are promoting a more intensive procurement and use of forest biomass. While it is a fact that increased biomass harvesting generates greater nutrient losses from forest ecosystems relative to stem-only harvesting, the use of nutrient budget approaches as a decision support tool in managing forests under intensive biomass removal is uncommon. This lack of use can be explained by several factors including: large uncertainties in predicting certain fluxes, the poor representation of nutrient dynamics following harvest in nutrient cycling models, the lack of representation of biological feedback, the lack of appropriate validation, and finally the lack of maps of specific soil properties that would be required to predict nutrient budgets over forest landscapes. This review documents the impact of intensive biomass extraction on nutrient cycling and discusses the gaps in knowledge and the uncertainties associated with nutrient budgets. It identifies research and development issues that need to be resolved for making forest nutrient budgets more reliable and more useful to address the questions regarding the environmental sustainability of intensive biomass harvesting.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
