Foliar Analysis

Fresh new sitka spruce foliage

Our top performing foliar analysis service offers a comprehensive range of standard and specialist tests to determine the chemical composition of leaf and foliage samples. We identify nutrient deficiencies and can provide tailored fertiliser prescriptions to boost plant growth, yield and quality.

Service overview

We provide a comprehensive suite of chemical analyses and tests for leaves and foliage. Tests results can provide important data on nutrient deficiency (nitrogen, phosphorous, potassium and trace elements) and help to monitor the progress of fertiliser regimes.

The laboratory is one of the top performers in Europe for plant analysis, ranked first out of 59 European laboratories in the annual plant analysis proficiency scheme run by the EU’s Protection of Forests Against Atmospheric Pollution programme.

Unlike many commercial analytical laboratories and testing centres, we always run calibrated controls with certified reference material to maintain the quality of our data and assess any significant drift or change in sensitivity. You can be sure that data from our facility will be suitable for detailed research analysis and long-term monitoring programmes, especially for soil improvement programmes.

Fertiliser prescription

Our foliage analysis + fertiliser prescription package is a value added service. Our experts compare results from deficient and healthy samples from the same area (e.g. a block of woodland) and combine this information with site details to develop a customised fertiliser ‘recipe’ and application programme.
This bespoke service offers a highly cost-effective pathway to optimise soil improvement for higher yields and healthier crops and trees.

Standard tests

  • Nitrogen, phosphorus, potassium, magnesium and calcium (NPK, Mg, Ca)
  • Metals and heavy metals (Al, Fe, Mn, Cu, Zn and Cd, Cr, Ni)

The results reported will indicate the normal and deficient levels of these elements. Additional and specialist tests are available on request.
