4 steps to better POUR-THROUGH TESTING

摘要

Get non-destructive, rapid results with this method for in-house pH and electrical conductivity testing. The pour-through soil test method has gained popularity because it providesnon-destructive, rapid results. North Carolina State Uni- versity has been instrumental in conducting research on this soil test method (www.pourthruinfo.com). The pour-through method is especially useful for media con- taining resin-or plastic-coated controlled-release fertilizers that can easily rupture when removing soilsamples for the 1 soil:2 water (1:2) or saturated medium extract (SME) method. The pour-through method also works well with large pots (e.g., 2 gallons) or when growing in substrate bags, where it can be difficult to extract a soil sample needed for a 1
