Soil Information System™

Multi-step process with specialized equipment and proprietary software.

Delivers the most complete, accurate and actionable soil based information in a practical and cost effective way.

SIS™ based information can bring improvements to virtually every aspect of the farm operation.

Key SIS™ advantages Efficient data collection – the SIS™ can collect high resolution soil information

at the rate of 50+ acres per day; at lower resolution data collection is even faster.

Rapid data turnaround – data is transferred digitally from the field to SIS™ data processing centers where information products can be generated in minutes to days.

Smart sampling algorithms – probe and soil core sampling locations are intelligently targeted to best represent the soil and chemical variability that exist in a field at the specified sampling density. This maximizes the value of collected data.

Smart data filtering – uses preexisting soil and landscape information as well as an intelligent rule base to make real-time checks during data collection that verify data quality and that sufficient field observations have been collected to create accurate soil maps.

Intelligent data processing algorithms – detailed soil-landscape information is used to reveal soil patterns for production of very accurate soil property maps.

Commercially used at over 600 sites in 8 countries on 4 continents.

Uses sensors such as EC or GPR, and a survey grade GPS unit to evaluate spatial variability of the soil and topography across the site.

With proprietary software, smart sampling locations are identified for further analysis.

Proprietary software analyzes data from first 2 steps. Locations are identified for collection of soil samples.

SIS™ methodology enables a “smart sampling protocol”, insuring the most accurate analysis of the field’s variability of soil characteristics.

Proprietary correlation and geo-processing algorithms are used to transform data to soil properties.

Mapping Tool

Using flexible suites of SIS data appropriate to the management objectives, fields are subdivided into areas that minimize in-zone variability.

Fertility ZonesSIS application maps and data analysis techniques make it possible to determine variable amendment needs. With this information growers can avoid under and over application of soil amendments and increase profits.

Fertility Solution

The SIS generates the detailed physical and chemical property information necessary to unravel the puzzle of soil variability that affects your bottom line. By using SIS technology in your fields, the benefits of variable rate fertility solutions can be realized.

Compaction Solutions

Using the SIS, you can precisely identify a field’s compaction characteristics and save money by only addressing areas where there is a clear problem.

Compaction (psi) – summarizes average soil compaction over precisely delineated horizons.

For viticulturalists trying to survive in the global wine market, new tools are essential to lifting one’s game in the never-ending effort to improve wine quality in a predictable and repeatable way.-Dr. Cliff Ohmart—Wines and Vines

The SIS™ has taken the guesswork out of the development and management of my vineyard properties.-Gary Bergevin, Bergevin Springs Vineyards – Walla Walla WA

We rearranged some of our existing vineyard block layout based on the SIS™ information. It has helped us improve planning by providing one of a kind, complete information about our soil and topography. It has proven valuable and I’d recommend the services to others.-David Gates, Ridge Vineyards – Sonoma CA The SIS™ could change the wine industry through better farming. - Wine Business Monthly
