GREENHOUSE GAS DYNAMICS IN A TREE-BASED INTERCROPPING SYSTEM COMPARED TO AN ORGANIC CONVENTIONAL SYSTEM
Bibliographic record
Abstract
Tree-based intercropping (TBI) system has been suggested as an alternative to conventional monocropping (CM) for decreasing overall greenhouse gas (GHG) emissions. However, little is known about the advantages of TBI compared with organic CM system with low fertilizer inputs. This project compared CO2 and N2O dynamics in replicated TBI and CM in Saint-Paulin (QC, Canada), established about 12 yr prior to this study under organic production, with horse manure and pruning residues as soil amendments. An experimental field, using a complete randomized block design, was instrumented in both systems. A five-point sampling transect was established between tree rows in each of the six plots. Surface CO2 and N2O fluxes, CO2 and N2O soil concentrations, and other physicochemical properties were analyzed at 0.125 and 0.25 m depths over two growing seasons. CO2 and N2O concentrations in TBI soil were similar to or lower than in CM soil. Lower CO2 and N2O emissions suggest that TBI would decrease overall GHG mitigation, even when compared with organic production with low fertilizer inputs, in addition to its potential for carbon sequestration in wood and other advantages that are not discussed in this study.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
