Soil Testing Time in South Texas

Posted on by

The Mid-Coast IPM Program is equipped to soil test with a hydraulic soil probe that samples to a depth of 24″.  Since 2013, we have sampled fields in Calhoun, Refugio, and Victoria Counties and found soil nitrogen levels ranging between 11 and 168 lbs N per acre. This can be a opportunity to reducing costs without affecting yields. Average fields can save $15-$20 by reducing fertilizer rates based on soil tests to 24″. You may find this service from several different sources including your IPM program in Calhoun,… Read More →

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.

Testing for Residual Soil N can Save $ – Corn

Posted on by

Two trials were conducted in 2017 the objective to evaluate the effect of reducing by the amount of residual nitrogen found in soil tests at depths up to 24 inches. Each of these trials were conducted with large plots in grower fields. What follows is the research report for the Corn test. (printable version) Evaluation of Reducing Nitrogen Fertilizer Application by Residual Soil Nitrogen Found to Depths Of 24 Inches in Corn Investigator: Stephen Biles and Geri Kline Cooperator: Clay Brett                            Summary A field research trial was conducted… Read More →

It is Soil Testing Time!

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.  I am looking for fields  to demonstrate this idea.  I want to conduct field trials in Calhoun, Refugio and Victoria counties on cotton, corn and grain sorghum.  I will do the soil sampling and have analysis done at the Texas A&M Soil Testing Lab.  Please contact me to discuss these field demonstrations (361-920-1138). In 2013, we sampled 53 fields in Calhoun County and found… Read More →

Soil Testing for the 2017 Crop

Posted on by

Once the 2016 crop has been harvested, it is time to look at testing the soil for the nutrient content required for the next crop.  Extensive research has been done on soil testing over the past 20 years resulting in the recommendation of testing soil annually for nitrogen content to a depth of 24 inches. Sampling conducted recently in the Port Lavaca area found residual nitrogen levels as high as 134 lbs available nitrogen per acre.  In fields with clay or loam soils, the amount of nitrogen found… Read More →
