• Soil health in the vineyards of North-Western Italy (2026) · Frontiers in Soil Science · doi

  The study was limited by the availability of data in regional databases. Many physical, hydrological, and biological properties were lacking. The improvement of soil structure thanks to organic matter was not fully considered.

• Decrease of soil total and organic phosphorus with ectomycorrhizal tree dominance in a subtropical mountainous forest (2026) · Journal of Soils and Sediments · doi

  The paper identifies a gap in the understanding of the relationships between soil phosphorus fractions and environmental variables. It also identifies a gap in the understanding of the effects of ectomycorrhizal tree dominance on soil phosphorus content.

• Differential Responses of Community Biomass Stability to Short-Term Nitrogen and Phosphorus Inputs in Two Dominant Plant Communities of the Songnen Grassland, Northeast China (2026) · Plants · doi

  The effects of nitrogen and phosphorus additions on biomass stability in different plant communities are unclear. There is a lack of understanding of how biomass stability responds to different nutrient addition treatments. This paper aims to fill this knowledge gap.

• Contrasting impacts of long-term nitrogen and phosphorus additions on the quantity and quality of soil dissolved organic matter (2026) · Soil Ecology Letters · cited 1× · doi

  Further research is needed to examine the effects of nitrogen and phosphorus additions on soil organic matter and dissolved organic matter in different ecosystems. The study highlights the need for long-term experiments to examine the effects of nitrogen and phosphorus additions on soil organic matter dynamics.
