Soil and Water Testing
A routine soil test can prevent a "shot in the dark" concerning fertilizer applications and pH. General soil tests consist of 15-20 core samples per location, each core going 6-8" deep, minus any debris (ex: turf from the soil surface, rocks, or mulch). The cores should then be combined and mixed to get a good representative sample of your specific location. One quart of soil is an adequate amount to submit for analysis. Soil probes, to assist in the sampling process, are available for checkout from the extension office. Routine soil samples are $10 per sample (cash or check) and can be dropped off at the Cleveland County Extension Office, 601 E Robinson, Norman, Oklahoma.
We can also test soil salinity, manures, compost, hay, and forage. For more information see the price list or contact our office at (405) 321-4774.
