about us

SoilOptix® provides the highest definition soil nutrient and texture maps to farmers, allowing for greater accuracy in management decisions on a field to field scale.​

Our History


SoilOptix® was established in 2017 as a partnership between Hubei Forbon Technologies, a large, progressive Chinese fertilizer company & Practical Precision, an influential precision ag technology company in southwestern Ontario. 

Practical Precision was founded by Paul Raymer & his father, Barry, who were influential in developing the Greenseeker & Y-Drop technologies on farms across the country, making them the first dealer in North America to sell the two as the ultimate side-dress system.

The technology used in the SoilOptix® sensor originated in the Netherlands as a tool for the geological industry, before coming to Canada in 2010. Practical Precision saw the potential in the technology and began further researching the use of gamma radiation in agriculture to develop nutrient and texture maps of the soil. 

With Barry since retiring, Paul operates SoilOptix® as a stand-alone company with it’s office located in Tavistock, Ontario, Canada.

Over the past 3 years, SoilOptix® has grown to be a global player in the agriculture industry, with dealers offering high resolution soil mapping services in over 10 countries.

As our service offering & dealership network grows, so does our in-house team. SoilOptix® has a full team of GIS Analysts that work tirelessly to produce the highest quality soil maps, & a team of Sales, Support & Admin staff who keeps the company running like a well-oiled machine.
