    soil testing

    Regular testing helps develop and maintain more productive soils for farming, gardening, and landscaping. Soil tests indicate whether plant nutrients are deficient and, if so, what amounts are needed for maximum growth. Soil testing is also a useful diagnostic tool to identify problems related to excessive levels of nutrients and salts, high pH, low organic matter, and poor drainage. When properly interpreted, soil tests promote more favorable conditions for productive and aesthetically pleasing gardens and landscapes.

    Boxes and instructions are available in our office, or forms can be printed off, at home by visiting USU Analytical Lab. A routine soil test costs $25 and tests the pH, salinity, texture, P, K, and offers recommendations. Samples are sent by the customer to the USU Analytical Lab located in Logan, Utah. Results are sent in about 10 days.
