A global meta-analysis on the effects of organic and inorganic fertilization on grasslands and croplands

T. Shi, S. L. Collins, et al.

This meta-analysis reveals how organic and inorganic fertilization impact grasslands and croplands worldwide. The research conducted by Ting-Shuai Shi and colleagues shows that while both fertilizer types boost aboveground biomass, inorganic choices reduce plant diversity. Notably, organic fertilization enhances soil organic carbon, particularly in conducive climates. Discover how organic practices can bolster ecosystem services without sacrificing biodiversity.

Abstract
This meta-analysis examines the effects of organic and inorganic fertilization on grasslands and croplands globally. Data from 537 experiments show that both fertilizer types increase aboveground biomass, but only inorganic fertilization decreases plant diversity. Organic fertilization increases soil organic carbon (SOC) more than inorganic fertilization, particularly in grasslands with higher soil water content and warmer temperatures. The study highlights organic fertilization as a potential nature-based solution for enhancing grassland ecosystem services without compromising biodiversity.
