Prism Agriculture offers a service as part of a site visit to collect soil samples, plant tissues or water for independent analysis at a Defra approved, UKAS Accredited laboratory.

Soil Testing

Soil, Water and Plant tissue analysis is an important part of good agricultural practice and fundamental to the decision-making process in agricultural and horticultural businesses, whether that’s for grassland management, arable cropping, horticulture or planting fruit trees.

Due to an increased demand within the supply chain for food traceability, from agricultural commodities to primary producers, through to UK consumers, there is now greater need to justify agrochemical and fertiliser use through soil testing, plant tissue and water analysis. Although it’s stated, in various codes of good agricultural practice, Defra now recommends analysis to minimise the risks of pollution to the environment also.

During a site visit, Prism Agriculture can collect soil samples, plant tissues or water for analysis, the samples are then sealed and dispatched with relevant paperwork to a fully independent, Defra approved, UKAS accredited laboratory, who work to the internationally recognised standard for competence – ISO/IEC 17025. Upon completion of analysis, reports will be emailed to you.

Prism Agriculture offers the following tests (If you can’t see the specific test you require, please contact us as it will likely be available):
