FULL SOIL TESTING

As well as our accurate in field pH testing service we also offer

SOIL TYPE MAPPING USING CONDUCTIVITY SCANNER & GPS

A low cost but very accurate way of precision farming

Scanning
We use hi tech GPS equipment linked to an electro magnetic soil conductivity meter mounted on a quad bike.

We first map the perimeter of the field and then scan the entire field using tramlines where possible

The data is logged on to a laptop or handheld computer

.scan

Results
Back in the office we produce the reports and maps showing the different soil type areas within the field.mapmap

Results can be given in either hard copy reports or data form.

These maps show clear variation in soil type even when the soil seems fairly even. With differences in soil type usually comes difference in soil nutrient status, susceptibility to compaction and requirements for different seed rates.

After the scanning has been carried out we can do a soil test for pH, P, K, Mg and any other nutrient which may be of interest for the crop being grown.

The soil is sampled by taking a lot of individual cores from each soil type area as marked on the scanning map. These cores are grouped together and sent for laboratory analysis. If a detailed lime test is required each core is individually tested for pH.

Benefits

  • Allows site specific application of fertiliser and lime.
  • Economical yet extremely accurate soil testing.
  • One off scanning cost.
  • User friendly data.
  • Useful and practical information.
  • Seed rates can be varied according to soil types.
  • Cultivation or mole drainage may only be necessary in parts of a field.
  • Enables economical application of sprays where weeds are soil type specific.
  • Can answer questions raised by yield monitors.
  • It is possible to take a sample to every hectare, but it is more expensive.
  • Soil type is a better guide to soil nutrient variation than neat 1 ha blocks.
  • There is considered to be a link between PCN and soil type.
  • A minor adjustment of the scanner can highlight areas of poor compactaction.
  • Useful for assesing viability of land before rental or purchase.
  • Nitrogen soil tests are more accurate if divided into soil type.
