North American Project to Evaluate Soil Health Measurements Dataset

These data were collected as part of the Assessing and Expanding Soil Health for Production, Economic, & Environmental Benefits grant to the Soil Health Institute. Because the primary objective was to evaluate, identify, and recommend effective widely-applicable measurements for evaluating soil health across North America, the project is often referenced as the North American Project to Evaluate Soil Health Measurements. The data available are a compilation of data collected and curated by Soil Health Institute from 94 long-term agricultural research sites across the United States and Mexico. Metadata includes location (lat/long) for each site, name, year it became a research site, 10-year summary weather variables based on the Daymet daily surface weather data set, year each treatment began, the categorical management attributes and detailed management data, and other metadata. 508 treatments are represented. Data is provided for 1453 experimental units (plots) that were sampled. 110 analyses (data columns) are reported for each experimental unit. Five more data columns are provided on nutrient analytes (ammonium acetate extraction, DTPA extraction, Olsen P) that were performed conditional on pH. Phospholipid Fatty Acid (PLFA) reports are provided on 109 biomarkers.

The NAPESHM project is part of a broader effort titled, “Assessing and Expanding Soil Health for Production, Economic, and Environmental Benefits”. The project is funded by the Foundation for Food and Agricultural Research (grant ID 523926), General Mills, and The Samuel Roberts Noble Foundation.
