Soil pH MSP

The evidence is in:

 

With typical grid sampling, soil samples are taken every 330’ (100m). Computer software fills in the gaps to make a nice-looking lime spread map. But there’s a serious problem on most fields: pH varies more than grid sampling can handle. When 2.5 acre (1ha) grid lines are overlaid on pH maps from the Veris pH Manager, the pH variability within each grid is fully exposed—and the pH within each grid can vary as much as it does in the entire field!

 

The product is ready:Independent university research and the results from satisfied customers all point to the same fact: on-the-go pH mapping from the Veris pH Manager is both proven and profitable. The payoff is up to you:How much you save will depend on your fields and your local lime costs. Typically, 1/3 of a ton of lime can be saved or redistributed to where it’s really needed. If lime costs $30/ton or more, the full cost of the mapping is paid back immediately.

 

About the Machine

This is the world’s first commercially available on-the-go sensor for soil pH—or for any soil chemical property. How it works is surprisingly simple, in fact it has only one moving part—a soil sampler shoe. Think of it like a large soil probe on its side. When the hydraulic cylinder pushes it in the ground, soil flows through. When the cylinder picks up the shoe, the soil in the shoe trough is pressed against pH electrodes. After a few seconds the shoe is lowered again to collect more soil. As it does, the new soil coming in moves the previous soil sample out the back of the shoe trough—and spray nozzles clean the pH electrodes. The shoe raises, and the process is repeated—with no action from the operator and no stopping. Approximately 10 samples per acre, thousands of samples per day—delivering affordable, accurate maps of pH variability. The Veris pH Manager is built on the Mobile Sensor Platform (MSP). This means other sensor modules-such as the OpticMapper, can be added to the platform. Customers can get started using the MSP with EC-only, and add the pH Manager in the future. The MSP implement can be configured as a 3-point tractor mounted unit, or equipped with a front tongue in a pull-type mode.

Veris pH Detector

The new pH Detector is an ATV-mounted pH mapping system capable of intensely mapping several hundred acres per day. The operator lowers a probe chamber into the soil with an easy-push mechanism. As the handle is lowered, a durable metalloid pH electrode is inserted into the chamber, contacting the soil at the bottom of the cavity. pH measurement is completed in 7-10 seconds. Geo-referenced data logging and pH electrode cleaning are all automatic.
