Featured PhD studies
Carmen Magro, PhD
Soil moisture & turfgrass science
Carmen Magro's doctoral work at the University of Padua examines soil moisture monitoring in amenity turfgrass ecosystems. His published research with collaborators explores root-zone sampling, measurement depth and the interpretation of soil moisture and salinity on golf course putting greens.
Considerations with determining optimum soil depth for soil moisture and salinity measurement on golf course putting greens
Carmen Magro, Stefano Macolino, Cristina Pornaro & Michael A. Fidanza
International Turfgrass Society Research Journal
Examines soil moisture and salinity by depth in sand-based putting-green root zones. The study considers how vertical differences influence the choice of measurement depth.
Why it matters
Measurement depth matters: one reading at one depth cannot automatically describe the entire root zone. Findings concern the sampled putting greens, not every soil or plant type.
Considerations with Determining the Minimum Number of Volumetric Water Content Measurements for Turfgrass Root Zones

Agronomy · Volume 12, Issue 6, Article 1402
Explores the number of volumetric water content measurements needed to characterize turfgrass root zones, addressing the challenge of representative soil moisture sampling.
Why it matters
Spatial variability makes sampling design important. A single spot measurement may miss differences across a managed turf area.

Partnership · Validation in progress
Checking water-treatment claims against the soil.
GroundWorx is partnering with RainMaker.earth to use our sensors to independently evaluate the soil response to their irrigation water-treatment system. Validation is in progress; no partnership results or savings figures have been published.
A fair evaluation establishes a baseline, compares treated and untreated areas where practical, and accounts for soil, weather, irrigation and maintenance differences. This is a proposed evaluation framework, not a published trial protocol or completed study.
No partnership savings figures or completed results are published. Soil readings do not directly measure plant uptake or gallons conserved; water-use records and agronomic checks are needed. Existing GroundWorx case studies are separate.
Figures are general agronomic guidance and typical ranges. Actual targets vary by site, soil, climate and season — GAIN learns each location's own baseline.
Direct publications and their scope appear on each individual profile. Species references are not evidence of cultivar-specific performance, universal irrigation targets or GroundWorx product outcomes.
