As part of our full spectrum of services, Prism Agriculture offers site visits to collect soil samples, plant tissues or water for independent analysis at a Defra approved and UKAS Accredited laboratory.
Whether it’s for grassland management, arable cropping, horticulture, or orchard planting, the analysis of soil, water, and plant tissue is an essential aspect of good agricultural practice and is fundamental to the decision-making process in all agricultural and horticultural businesses.
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 a greater need to justify agrochemical and fertiliser use through soil testing, plant tissue, and water analysis. Although it has been clearly stated in various codes of good agricultural practice, Defra now also recommends soil testing and analysis to minimise the risks of pollution to the environment.
During a site visit, Prism Agriculture will collect soil samples, plant tissues, or water for analysis. The samples will be sealed and then dispatched along with the appropriate paperwork to a fully independent, Defra approved, UKAS accredited laboratory working to ISO/IEC 17025 – the internationally recognised standard for competence. Upon completion of laboratory analysis, reports will be furnished to you via email.
For your needs, Prism Agriculture offers the following soil tests (If you don’t see the specific test you require, please contact us as it will likely be available):
