Review And Execute Your Soil Sampling And Analysis Plan

Author: Chad Kalaher

As harvest begins, it’s extremely important to review and execute your soil sampling and analysis plan. Due to potential sampling and lab screening delays, don’t wait until all your fields are harvested to initiate this process. Be sure to ask for soil test analysis including the basics plus CEC, base saturations and micronutrients. In 2015, spring soil and tissue samples collected during the growing season continue to indicate common nutrient deficiencies that are not being addressed in many fertility plans. Many farmers who have their pH, phosphorus, and potassium at optimum soil test levels may be ignoring important yield-limiting nutrients.

NE Illinois & NW Indiana: Zinc, Tissue Sampling, and Wheat Progress

Author: Chad Kalaher

ADD ZINC TO YOUR STARTER FERTILIZER PROGRAM
One of the common questions I have been getting lately is definitely not a new one. “Should I be using liquid starter fertilizer at planting for corn?” While some farmers in the Midwest have been using starter for many years, others are just getting started.

TISSUE SAMPLING FOR HIGHER YIELDS
Have you mastered the “Seven Wonders of the Corn Yield World” and “The Six Secrets of Soybean Success?” Most likely, your answer is “No, but I give it my best shot to control what I can!” Although Dr. Fred Below’s recipes do not include foliar nutrition, plants lacking optimum levels of macro and/or micronutrients usually fail to produce high yields.

WHEAT CROP STATUS UPDATE
The wheat crop in our area has gone through one of the coldest winters on record. Growth stage currently ranges from Feekes 2- Feekes 4. Using October 12 as a planting date, we are 321 wheat growing degree days (GDDs) behind the previous year through April 12. If we have average temperatures in the last half of April, this will correlate to a two week delay. Given that some fields didn’t get planted until the last week of October, we are closer to a delay of 3-4 weeks.
