Soil Mapping

Q. Can soil mapping test for fertility?
A. No. Soil mapping essentially uses GPS coordinates to identify where soil changes from clay to sand and in between, and create zones of similar soil types.  These different soil types can have different fertility needs.   Fertility tests are done separately inside the zones.  Soil mapping is done once.  Fertility testing can be done every year.

Q. Is soil fertility testing included in the cost of soil mapping?
A. No. Soil mapping costs are separate from fertility testing costs.   Fertility costs occur after mapping is complete and within the mapped zones.

Q. How often should I test soil for fertility?
A. If soil has not been tested for a long time, the best time to test is now. Most soils can usually be remediated within 3 to 5 years, some sooner.  Most soil labs can track results so that nutrients can be tracked to see yearly changes. Testing annually determines how quickly the soil is getting into balance.

Q. What are the results of soil mapping used for?
A. Soil mapping helps you know where to test for fertility. Soil mapping is what fertilizer companies use to variable rate spread so that farmers can add what is needed, where it is needed.  This practice mimimizes over fertilizing, which can lead to runoff  and maximizes yields.

Q. How do I read a soil map?
A. Soil Technologies will map your soil and give you a coloured map that will show you the “zones” in your field and the acreage for each zone.

Q. Who owns the soil mapping data?
A. The customer owns the soil mapping data.

Q. How long does it take to get the soil mapping?
A. Soil Technologies can usually map a field within 24 – 48 hours, weather dependant.

Q. What is the turnaround time beginning with the soil samples to the receiving of the nutrient recommendations?
A. Soil Technologies can usually return test results within two weeks depending on the demand of the lab.

Q. Can these results be used for tax assessments?
A. Yes. If the soil EC mapping determines that the amount of clay and sand is different than a tax assessment shows, the EC mapping can help to support an appeal to  the tax assessment office.
