Veris Msp3

Map soil texture using soil electrical conductivity and produce precise maps of the soil variability in your fields.

Map organic matter with an optical sensor operating underneath crop residue and the soil surface.

On-the-go pH mapping uses pH electrodes to measure 5-10 pH samples per an acre.

MSP3 FAQs

Does it pay to have this mapping done?

The value of these maps will vary according to crop value and input costs, the degree of variability within each field, the number of years the map will be used, and other factors. It’s important to consider the errors inherent in less expensive maps. Research has shown that pH sensor maps improve lime application precision by an average of 1100 lbs/ac (1233 kg/ha) versus 2.5 ac (1 ha) grid sampling. Multiplying that by local lime applied cost calculates the value of that layer. Comparing OM and CEC maps from Veris sensors versus soil surveys reveals significant inclusions and errors in the old surveys. Applying several thousand corn seeds/acre above or below what your soil can sustain, could cost you hundreds, even thousands of dollars per field--every year you plant it to corn.

What are the operating costs?

The table below shows approximate variable operating costs for the MSP-3. Actual costs will vary with abrasive properties of soil, transect width, operator, maintenance and other factors.
  cost per acre cost per hectare
Soil EC    
coulter blades, bearings, seals, spring plungers $0.15 - $0.25 $0.35 - $0.60
Soil OM    
wear plates, row unit components: blades, bearings, tires, etc. $0.25 - $0.30 $0.50 - $0.75
Data processing fee $0.25 $0.60
Soil pH    
pH electrodes, solutions, soil engaging components $0.20 - $0.30 $0.50 - $0.75
Total 3 sensor operating costs $0.85 - $1.20 $2.05 - $2.15

How fast can I drive? How many acres can I cover per hour?

Mapping speed will depend largely on field conditions. 8 mph (13 km/hr) is the maximum recommended speed, and would only be possible in smooth fields. Rough and rocky fields will require a slower speed. The table below shows the acres mapped per hour at various speeds and transect widths. Remember: these are long-term maps that will be used to apply many valuable inputs—so data quality is critical. In some conditions, pH sampling can require a 4-6 mph (6-10 km/hr) speed to optimize soil flow. In order to maintain overall daily mapping production, it may be advisable to map pH only on alternate transects, allowing increased field speed on transects where pH sampler is disengaged. This still provides 4-6 pH samples per acre (10-15/ha)—significantly more than conventional grid sampling.
