Does urease in soybean meal need to be tested for every truckload?
--------------------------------------
We test every truckload, using the simple phenol red rapid method

Use the simple phenol red method for a rough test of incoming soybean meal, and for batches near the qualified limit, calibrate with the titration-PH (quantitative) method. This is the method after revision of the national standard; the previous national standard was the pH increase method.
