- Soils may be depleted
- Routine soil tests recommended
- Sampling techniques
Moreover, in recent work in Nueces County, deep soil sampling found a significant amount of plant nutrients stored in the soil profile down to 24 inches. In fact, in two separate studies this past year in grain sorghum crops soil samples collected to 24 inches contained 117 and 159 pounds per acre of plant available nitrogen prior to fertilizer application. Research plots at these sites fertilized at traditional rates produced the same yields as those that were not fertilized, because residual, stored nutrients were sufficient to meet plant needs. This makes a strong case for soil testing and for sampling at depths greater than 6 inches.
The Coastal Bend Soil Testing Campaign, coordinated by local offices of the Texas AgriLife Extension Service, for farms in Aransas, Bee, Jim Wells, Kleberg/Kennedy, Live Oak, Refugio, Nueces, and San Patricio Counties is underway now through November 30, 2010. Soil samples may be turned in at your local County Extension Office for analysis at up to a 33 percent reduced testing fee.
Soil tests will be run by the Texas A&M University Soil Testing Laboratory for a reduced fee of $6 per sample for the Routine Analysis and $10 for Routine /Micronutrient Analysis during this campaign. This special soil testing campaign is for row crop farmers and ranchers with improved pastures. Soil sample bags and test information sheets may be obtained in the County Extension Office.
