# Dryland Soil Restoration Meta-Analysis Data

Data extracted from published literature on soil-based restoration experiments in dryland environments.

## Description

Study_ID: random ID assigned to each unique study
Aridity_Index: aridity index of the study site (0-0.65)
Perc_Sand: percent soil sand of the study site or substrate used (0-100%)
Trt_Type: type of treatment used (Abiotic or Biotic)
Revegetation: whether or not seeding or revegetation was done in tandem with the soil treatment (Yes or No)
Time: time since the treatment was applied (in years)

LRR: log response ratio (measure of effect size)
Var: within-in study variance (used to conduct meta-analysis)

Stab: aggregate stability (1-6 rating)
Bulk_Dens: bulk density (g/cm^3)
VWC: volumetric water content (%)
SOC: soil organic carbon (g/kg)
SoilN: total soil nitrogen (g/kg)
MyC: mycorrhizal colonization (% of root length colonized)
Resp: basal respiration (mg CO2/kg/day)

For example, "Stab_LRR" = the log response ratio for aggregate stability
