Papers reporting a negative result or no effect 1

Wood gasification biochar enhances soil carbon sequestration without affecting greenhouse gas fluxes or wheat yield in sub-alkaline soil · 2025
- no effect
  Biochar left soil greenhouse gas fluxes unchanged.
  compared with unamended wheat (control)

A paper is on the positive side when any of its claims here is positive. Claims are grouped by organism, treatment and what was measured or targeted. Claims that compare genotypes are left out; a claim about lacking a nutrient counts the other way round in that nutrient’s question. “Results differ” marks a question where two model reviewers, reading both claims, accepted at least one pair of papers whose results differ.
