GPS Nutrient Mapping with Soil Sampling Data
GPS soil sampling results are used
with field outlines to create GPS nutrient maps to
show any differences in soil nutrient status within a field or farm.
Some fields are relatively uniform whilst others may show big
differences. Field outlines can be created independent of soil
sampling by GPS mapping service in
Suffolk, Norfolk, Essex and Cambridgeshire in the UK by
Willington Crop Services
GPS
farming services.
Farmers can often predict whether fields will have no
differences or big differences based on local knowledge. For example,
fields that generally yield fairly evenly are less likely to show big
differences, and likewise fields with uniform soil type are less
likely to reveal big differences.
However fields regarded as fairly uniform can some
times give variable soil nutrient analysis, and highlight untapped potential in parts of fields.

pH Map pH over 7 is coloured white. Shades of red indicate areas of less than pH7, and darker shades indicate more acidic soils requiring lime to neutralise acidity. |

Phosphorus Index
(P Index) Phosphorus indices are shown as shades of blue. The darker the shade of blue indicating areas with less phosphorus nutrient in the soil and requiring more phosphorus fertiliser. |
![]() |
Potassium Index (K Index) Potassium indices are shown as shades of green. The darker green indicates area of field with less potassium nutrient requiring more fertiliser. |
![]() |
Magnesium Index (Mg Index) Magnesium indices are shown as shades of yellow. The darker yellow indicates area of field with less magnesium nutrient in soil and requiring more magnesium fertilizer. |
GPS Nutrient Maps
GPS data from soil
sampling is used to create nutrient maps used to create fertiliser
application maps for each field for GPS fertiliser maps to
optimise fertiliser applications based on soil nutrient
status, crop grown and rotation. See

Services in Suffolk, Norfolk, Essex and Cambridgeshire in the
UK.
