Soil Sampling in a Conventional W PatternConventional W Soil Sampling is the collection of one set of soils per field, irrespective of field size. 25 soil cores taken in a W pattern across field - hence the term W soil sampling, as opposed to GPS Soil sampling which is more detailed.
W Soil Sampling Field
W soil sampling is normally across the whole field.
But for large fields of more than 10ha, the
field can be divided into approximate 4ha areas of fields to identify
differences within the field. Soils sampling is by collecting soils
from each 4ha area in W pattern to produce a single soil sample for
W Soil Sampling 4ha areas of field
Soil samples or plant samples are analysed for what ever elements the farmer requires. Standard soil analysis for fertilizer requirements is pH, P, K, Mg but other elements can be analysed such as soil texture, organic matter, boron etc.. Laboratory results are returned with recommendation to interpret results for nutrient management.
Method for Soil Sampling Fields
- Collecting Soil Sampling Cores: W pattern walked/ driven across the whole field or part of field. Cores are amalgamated to give a single soil sample for laboratory analysis. The exact soil sampling pattern used depends on the analysis required.in Suffolk, Norfolk, Essex and Cambridgeshire in the UK
- 25 Soil Cores per Field or Field Area: Soil cores are taken along the W path across field or areas within the field. The 25 soil cores from within each field or field area are amalgamated into 1 soil sample for analysis.
- Laboratory Analysis: Soils are sent to laboratory for analysis, results are within 10 working days from sampling. Results are interpreted with recommendations on the nutrient management needed.
- Comparison to Previous Years Results:
Customers results from previous years are included in data
returned for a full picture of
field reserves. Results returned on paper/ email or data format
required for import into farmers own crop management system.
