2017 Soybean Tissue Trends

Identifying what is going on inside your plants can be challenging.  The plant will give us visual signs of distress, but some of those signs could mean several different nutrient deficiencies.  Tissue sampling is a tool to help nail down what is really going on with your plants.  In 2017 Centra Sota submitted 288 soybean tissue samples. Copper was the most deficient micronutrient followed by manganese. 

Copper was most deficient during the R1-R2 growth stage. Visual signs of copper deficiency can be intervenial chlorosis on new leaves.  The leaves at the top of the plant are more susceptble to wilting.  To fight a copper deficiency a foliar application  during the V3-V5 growth stage or early repoduction stage using a copper product such as Max-In Copper product.   

Manganese was more deficent during R1-R2 growth stage. Visual signs of a manganese deficiency is interveinal chlorosis followed by necrosis. To fight Manganese deficiency a foliar appilcation of a Manganese product such as a Max-IN Manganese can be added to your fertilizer application.  The application window will be between V3-V5 growth stage and R1-R2 growth stage.

Work with your Centra Sota Crop Advisor to review current tissue samples results and create a game plan to tackle those deficient nutrients.
