GPS Soil Sampling and GPS Nutrient Mapping
GPS soil sampling provides the farmer with more detailed information about the variability of soils within each field or fields, for the elements analysed whether soil type or specific nutrient availability or pH. GPS is differentially corrected (dGPS) to precisely locate soil sampling points or areas within field. See Case study on GPS soil sampling.
Why choose GPS Soil Sampling?
GPS data on soil analysis results from GPS soil sampling can help you make more informed decisions on nutrient management.
Benefits of GPS soil sampling:
- Reduced spend on fertilizers and lime.
- Identify areas of
very low fertility and limiting crop yield potential.
- Farmer can better justify fertilizer use or non use across field.
- Fertilizers need only be applied to parts of fields with low soil indices.
How is GPS Soil Sampling done?
- Soil sample cores are collected from each grid area
on the ATV screen. The
numbers of soils & method of collection depending on the
analysis the farmer required. Cores from within each grid area
are amalgamated for a single soil analysis.
The position of each grid is recorded using differentially
corrected GPS.
* Soil Samples or plant samples are analysed at an independent laboratory GLP laboratory. Standard soil analysis is for pH, P, K, Mg. But additional nutrients can be added to this analysis.
* Willington Crop Services maps the soil sampling results to see nutrient variation across the field.
* GPS nutrient maps are created.
Plus fertilizer recommendations.
* Results of soil sampling are normally returned
within 14 days for standard soil analysis. Format of data is as
farmer specifies, in digital format to suit farm mapping
software &/or paper as required.
Prices on application dependent on exact needs.
