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 → 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 → 
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 → 
Welcome to part ten of the column series on soybean micronutrients. In previous weeks I discussed boron, chloride, cobalt, copper, iron, manganese, molybdenum, and nickel. I will quickly cover how zinc (Zn) is essential to soybeans, known deficiencies or toxicities in the region, factors of zinc availability in soil, soil and plant tissue testing, and […] Continue reading → Welcome to part nine of the column series on soybean micronutrients. The past several weeks I discussed boron, chloride, cobalt, copper, iron, manganese, and molybdenum. I will quickly cover how nickel (Ni) is essential to soybeans, known deficiencies or toxicities in the region, factors of nickel availability in soil, soil and plant tissue testing, and […] Continue reading →
