Biochar is widely used to remediate heavy metal-contaminated soils; however, it can increase carbon (C) limitation in soil microorganisms, potentially compromising soil ecological sustainability. Effective strategies are, therefore, needed to reduce heavy metal bioavailability while maintaining microbial activity and...

Alpine wetland conservation and restoration are reshaping wetland use and soil conditions on the Zoige Plateau, but how these changes influence phosphorus (P) cycling remains poorly understood, even though cold, waterlogged soils can constrain P availability and make P cycling critical for ecosystem functioning. Here,...

This study evaluated how wheat-straw input modifies the effects of 2% (w/w) wheat straw-derived biochar on Cd availability, soil physicochemical properties, enzyme activities, N transformation and microbial communities during a 49-day incubation. Combining 2% biochar with 6% straw reduced soil-available Cd by 7.14–14.2...

Soil acidification in apple orchards disrupts nitrogen (N) transformation and raises the risk of N loss. Using in situ 15N-urea microcosms in an acidified orchard (pH 4.46) in North China, we tested four treatments: N, phosphorus (P), and potassium (K) (CK, control); N, P, K plus organic fertilizer (NPKM); N, P, K plus...
