As spring approaches and winter wheat begins to green up, agronomists and farmers still have the opportunity to stimulate spring tillering on late-planted fields or those fields with thin stands with early nitrogen. If not applied in the fall, two other key nutrients, chloride and sulfur, can be included at green up during the early […] Continue reading → 
I want to take a moment to share with you some of my 2020 local accomplishments through the University of Nebraska-Lincoln’s (UNL) Water and Integrated Cropping Systems Extension Program. From a larger perspective, UNL may not always be front and center, but shines through the many of the farmers, agronomists, seed dealers, Ag retailers and […] Continue reading → 
This is the sixth column in a series on phosphorus (P) management proficiency. Last week I wrote about the importance of controlling and consistently pushing the soil probe to the appropriate depth. The UNL soil test interpretation and fertilizer recommendation based on a 0-8 inch sample for P. Additionally, collecting enough subsamples or cores to […] Continue reading → 
This is the fifth column in a series on phosphorus (P) management proficiency. Last week I wrote the about (Part 2) the study evaluating the differences in P management approaches in continuous corn production. In that same Nebraska study, they did soil sample analysis in 2-inch increments for soil P concentration. I think we will […] Continue reading → 
This is the fourth column in a series on phosphorus (P) management proficiency. Last week I wrote the about (Part 1) phosphorus management evaluation in a continuous corn study done in Nebraska. Today, I will dive into some other research findings besides yield and the fertilizer rates applied between the different management approaches. This research […] Continue reading → 
Last week I wrote about phosphorus (P) fertility philosophies or approaches. This week I am writing about Nebraska research that compared those phosphorus fertilizer approaches. This research was published in the 2018 Soil Science Society of America Journal by UNL faculty Wortmann, Shapiro, Shaver, and Mainz. One of the objectives of their research was to […] Continue reading → Last week I introduced the new extended series on phosphorus (P) management proficiency. This week I am writing about differing philosophies or approaches in managing phosphorus (P). The two major approaches are sufficiency and build-maintain. The sufficiency approach, also called deficiency correction, attempts to eliminate plant P deficiency in the current growing season based on […] Continue reading →
