Description
Quanquan Wei and ten colleagues tested whether biochar plus green manure can sustain maize yields with less nitrogen fertilizer. Excess nitrogen harms soil health and the environment. Either amendment alone is known to help, but their combined effect in yellow soils was underexplored. The twenty twenty-six two-year field study compared six treatments, from no fertilizer to full nitrogen with both amendments. A reduced-nitrogen treatment with both amendments was also included.
Full nitrogen plus biochar and green manure gave the strongest results. Yield, soil nutrients, carbon fractions, and enzyme activity all rose significantly over the control. That combination also produced the most water-stable soil aggregates. The findings support pairing the two amendments to protect soil while easing dependence on synthetic nitrogen.
