Time to Test the Soil for Nutrients

Fertilizer cost has been rising over the past year creating more need to test the soil in your fields for nutrient content and fertilizer recommendations.  Since 2013, we have sampled fields 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. On 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, Refugio… Read More →

Rain and its Impact on Crop Fertility

We have received rain in great amounts over the past few weeks. This morning, my rain gauge is full, and it’s still raining. Many fields have received over 10 inches of rainfall over the past few days. One question I have received is: “What is this rain going to do with our fertilizer?” The nutrient of greatest concern should be Nitrogen.  This is because of denitrification and the water solubility of Nitrogen. “Gaseous loss of nitrogen takes place by denitrification or ammonia volatilization. Denitrification is a process through… Read More →

Soil Testing Time in South Texas

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″.

It’s Soil Testing Time in South Texas!

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

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.
