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 → 
Welcome to part eight of the column series on soybean micronutrients. The last couple of weeks I discussed boron, chloride, cobalt, copper, iron, and manganese. I will quickly cover how molybdenum (Mo) is essential to soybeans, known deficiencies or toxicities in the region, factors of molybdenum availability in soil, soil and plant tissue testing, and […] Continue reading → 
Welcome to part seven of the column series on soybean micronutrients. The last couple of weeks I discussed boron, chloride, cobalt, copper, and iron. I will quickly cover how manganese (Mn) is essential to soybeans, known deficiencies and toxicities in the region, factors of manganese availability in soil, soil and plant tissue testing, and fertilizer […] Continue reading →
