Soil, Leaf & Water Services
SGS has the latest technologies and state-of-the-art laboratories for every phase of the agricultural production cycle. We analyze many analytes for your business including fertilizer, compost, topsoil, manure, agricultural water and residential soil. We test prior to remediation or restoration, to assist with benchmarking and areas of focus for amending. As the industry has evolved to focus on sustainability, we are leaders in providing data for soil health calculators. Our Guelph laboratory has various accreditations, building upon our commitment to precision. For plant tissue, our testing methods are ISO/IEC 17025:2017 accredited by Standards Council of Canada, plus our soil nutrient testing is accredited by OMAFA. Ensuring compliance with industry standards, we also participate in the North American Proficiency Testing Program for plant tissue and soil analysis.
SGS also provides reliable testing for clubroot and aphanomyces surveillance projects, and our CFIA accredited seed laboratatory is perfectly suited for weed seed identification in soil and topsoil at our SGS Sherwood Park laboratory. SGS is unable to process or conduct tests on soil samples imported from other countries, as well as those collected from areas within Canada that are subject to regulations stipulated by the Government of Canada Plant Protection Regulations.
NEW for 2025! SGS Guelph has attained PROGRAMME D’ACCRÉDITATION DES LABORATOIRES D’ANALYSE (PALA) accreditation, now offering agricultural soil testing in Quebec. Learn more by choosing Quebec Soil Testing Services HERE.
