The National Soil Survey Center (NSSC) – Kellogg Soil Survey Laboratory (KSSL) requires the acquisition of three particle size distribution analyzers (PSDA) to expand laboratory capacity for soil texture analysis. This increase in analytical capability is necessary to support the expected surge of several thousand soil samples associated with the Regenerative Pilot Program, which will require timely and accurate particle size data to meet project objectives.
