Data supporting meta‐analysis of multiple ecosystem outcomes from organic amendment additions to rangelands (https://doi.org/10.1111/gcb.14535)

Data extracted from 92 field studies of organic amendment (= carbon‐based amendment to which synthetic nutrients had not been added, including biosolids, composts, manures, green wastes, municipal solid wastes) addition to rangeland (= non-forested ecosystem with sufficient plant biomass to support livestock grazing). Data were extracted for 20 response variables: soil organic carbon, soil water holding capacity, soil lead (Pb), soil carbon dioxide emission (field), aboveground net primary production, plant species diversity, plant tissue nitrogen, plant tissue Pb, runoff quantity, runoff nitrate, runoff phosphorus, soil moisture, soil respiration (laboratory), soil microbial biomass or abundance, soil total nitrogen, soil ammonium, soil nitrate, soil extractable phosphorus, percent cover of annual plants, and percent cover of grass plants. Data about each study site and properties of the amendment applied were also recorded. See methods section of https://doi.org/10.1111/gcb.14535 for more details.
