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 → 
ALFALFA SOIL TEST: pH AND POTASSIUM – Megan Taylor So you pulled some soil cores and now you have the results in your hand, now what? On your soil test results you will want to check out pH, potassium, and phosphorous levels across all soil textures. If you have a lighter textured soil, check for […] Continue reading → I hoped you enjoyed the soybean micronutrient 11-part column series over the past three months that is archived at croptechcafe.org. Join me over the next three months in my second extended column series on phosphorus management proficiency. Phosphorus management was identified as a primary area of concern by members of the new Saline, Jefferson, and […] Continue reading →

One challenge is its impact on corn stalk feed quality. While this fall has been quite dry, there […] Continue reading → 
I introduced the weekly series in September and have since wrote about boron, chloride, cobalt, copper, iron, manganese, molybdenum, nickel and zinc. I covered how each micronutrient is essential to soybeans, known deficiencies or toxicities in the region, factors of micronutrient availability in soil, soil and plant tissue testing, and fertilizer recommendations. Interest and concern […] Continue reading →
