NRM is an agricultural and environmental laboratory and a trading division of Cawood Scientific Limited. It analyses soil, plant tissue, water and manures for farmers, growers and agronomists, and tests composted waste, anaerobic digestate and other organic materials applied to land. Cawood says NRM was formed in 1990 and analyses more than 450,000 soil samples a year for basic nutrients.
Its soil packages cover pH and major nutrients, trace elements, organic matter, texture, cation exchange capacity, mineral nitrogen and soil carbon. Cawood names its agricultural tests CarbonCheck, N-Check, GrainCheck and CropCheck, and says its agricultural analysis services are UKAS accredited.
