The Soil Fertility Experts at Texas A&M AgriLife Extension Service recommend soil testing fields for soil available nitrogen annually to a depth of 24 inches. The Mid-Coast IPM Program is equipped to soil test with a hydraulic soil probe that samples to a depth of 24″.
The cost for the IPM soil testing program is $2 per acre with a minimum of $45 per field.

Since 2013, we sampled fields in Calhoun Refugio and Victoria Counties and found soil nitrogen levels ranging between 11 and 168 lbs N per acre. In a time when farm budgets are being squeezed tightly, this can be a opportunity to reducing costs without affecting yields. You may find this service from several different sources including your IPM program in Calhoun, Refugio and Victoria Counties.
