Nitrogen Supply from Green Manure Enhanced with Increased Tillage Frequency: A Note
Bibliographic record
Abstract
Core Ideas Ion exchange membranes were tested for in situ evaluation of soil mineral N. More tillage passes increased green manure decomposition and soil mineral N. Ion exchange membrane were a good indicator of arugula N uptake. Pea–oat green manure supplied up to 20% of the N required by arugula. Tillage practices influence the decomposition of green manure and could be adjusted to synchronize the N supply from residues with crop N demand. This note evaluated ion exchange membranes (IEM) as an in situ tool for monitoring ammonium (NH 4 + ) and nitrate (NO 3 − ) dynamics after pea ( Pisum sativum L.)–oat ( Avena sativa L.) green manure was incorporated by one, two, or four passes of a rototiller. Mineral N from IEM and in 2 M KCl soil extracts was related to the cumulative N assimilated by arugula ( Eruca sativa L.) during a 6‐wk period. Greater tillage intensity increased the IEM‐NO 3 − −N concentration on ion exchange membranes significantly, from 1.94 to 18.7 µg cm −2 wk −1 , and the N supplied from green manure increased arugula N uptake significantly. The IEM‐N were as reliable as the soil chemical extractant in evaluating the mineral N released from green manure under field conditions.

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.
