GPS Soil Sampling

"GPS soil sampling or GPS plant sampling is only as good as the samples taken. Poor sampling gives poor results"

dGPS soil sampling gives you detailed information about the variability of the soil factor within your field or fields.

dGPS is used to precisely locate sampling points or areas within field. Soil samples or plant tissue samples are analysed by NRM laboratory and results are interpreted and recommendations provided as required.
Case study about GPS soil sampling

What is involved in GPS soil sampling?

- The field boundary is logged using ATV with GPS data logger mounted.

- A grid is superimposed onto the field outline, normally running in the direction of tramlines: grids are commonly 1ha but can be tailored as required.

- Field is divided into grids to suit sampling required. Soil cores are collected from each grid area, the numbers & method of collection depending on the analysis required: cores from within each grid area are amalgamated for analysis.
The position of each grid is recorded using differentially corrected GPS.
W i l l i n g t o n C r o p S e r v i c e s soil testing patterns

- Soil Samples or plant samples are analysed at an independent laboratory, NRM, Bracknell.

- Results are used to create a GPS soil map or GPS plant tissue map, results are plotted onto the field boundary as in examples below.
Recommendation or interpretations are mapped on additional maps.
Data returned by email &/or paper as required

EXAMPLE GPS SOIL MAPS

gps mapping of pH for lime needed
pH - pH>7 is coloured white and as shades
of red get darker the soils are more acidic.

gps field mapping of Phosphorus (P)
Phosphorus Index - darker blue indicates
area of field with less P in soil.

gps field map of potassium (K)
Potassium Index - darker green indicates
area of field with less K in soil.

gps map of field magnesium Mg
Magnesium Index - darker yellow indicates
area of field with less Mg in soil.

gps map of field pcn
PCN eggs/g soil - darker colour indicates area
of field with greater numbers of pcn, lighter
colour indicates fewer pcn.

Summary: dGPS is used for all GPS Soil Sampling and GPS Plant Sampling work. GPS soil testing of soil samples can be used to create GPS soil mapping, Willington Crop Services available in Suffolk, Essex, Norfolk, Cambs.
