How to Test Agricultural samples

Some of the methods above show that ISE’s can be used to measure not only aqueous samples but soil and plant extracts. Take a look at the hints and tips below to see how you can make successful measurements in the different sample types for a variety of key parameters such as Nitrogen, Phosphate, Sulphate, calcium and pH.

Direct Measurement

Aqueous samples can be measured directly for a solid indication of Ion concentration. You may require the addition of an ISAB or coarse filtration for accurate work but results will be quick and consistent.

Soil Measurement

Most ISEs cannot measure directly in soil. However all of the parameters of interest are water soluble and can be extracted quickly into an aqueous sample which can be measured quite successfully and quickly.

Contact us at info@edt.co.uk for practical advise on rapid methods for many parameters.

Plants and Foliage

It can be useful to know the level of e.g. Nitrate in plant tissue. Historically this is a complicated lab test. However it is often possible to remove plant extract and measure this small sample directly giving quick relative data.
