And helped Percy Skaling commercialize new measurement instruments in the field of soil physics, soil hydrology, and agronomy sciences. All these instruments are now considered necessary equipment for soil physics labs around the world.

The list of famous products introduced by SoilMoisture over the years include Tensiometers, Soil Moisture Retention Curve Systems, SoilMoisture Porous Ceramics, the Guelph Permeameter, the Trase TDR moisture sensor technology, Suction Cup Lysimeters, Plant Water Potential Consoles, and G-Blocks. Many of these products and instruments are now in soil hydrology and soil physics textbooks, and in regulatory documents, scientific publications, and professional standards all over the world. 

The official soil water retention coefficients published by the US Department of Agriculture in the 1980s were developed using SoilMoisture’s precision ceramics and instruments. To this day, the USDA’s National Soil Labs heavily rely on  SoilMoisture’s products for the development of the US National Soil Survey, a critical tool for nationwide crop production.  

In 1980, Dr. G.C. Topp from the University of Toronto published the Topp Equation, the first general-purpose soil moisture calibration for time domain reflectometry (TDR) which is widely used today in soil moisture probes. In the early 1980s, Dr. Topp’s collaboration with SoilMoisture  led to the first commercial portable soil moisture sensor  known as the Trase™ TDR technology.  

Building upon decades of legacy, SoilMoisture is a respected brand among educators, researchers, and experts in the fields of soil sciences, construction research, agronomy, environmental sciences, geology, mining, and oil industry. SoilMoisture is for many people the first option for their projects and is referenced in hundreds of scientific publications and articles. In other words, SoilMoisture is THE gold standard in soil physics and soil hydrology markets around the worldSoilMoisture’s products have become vital tools for society to assess challenges to agriculture, food security, and climate change. 

In October 2022, SoilMoisture Equipment Corp. was acquired from the Whitney Skaling family by Stevens Water Monitoring Systems, Inc. (Stevens Water) and Mr. Alan Farsad, PhD Soil Physics. Stevens Water brings their knowledge and technologies in environmental data acquisition, water resource and soil science monitoring, and turf, to SoilMoisture’s expertise in agronomy, TDR technology and scientific research instruments.

SoilMoisture and Stevens’ product offerings and services cover a broad range of soil monitoring applications for research, climatological monitoring, water resource forecasting, agriculture, golf, sports turf, civil engineering, property protection, and more.  SoilMoisture and Stevens will continue to build on our legacy and build on the reputation in innovative agronomy and soil science research and applications using quality products and solutions.
