Past Tissue Sample Trends

We have been dedicated to using tissue samples over the years to learn more on ways to help our customers grow better crops.  Here are some local trends we’ve identified along with insights from WinField United.
Full Circle Tissue Sample Trends

  • Micronutrients such as Zinc and Boron have a high percentage of coming back responsive or deficient from V4-V8.  Growers are managing phosphorus and potassium well which have a higher adequate percentage.



WinField United Nutrient Trends and Insights
Here are some nationwide trends revealed by tissue analysis conducted by WinField United in 2017.

  • Corn suffered from more nutrient deficiencies in 2017. Compared to 2016, corn plants saw increased deficiencies in key macro- and micronutrients, including nitrogen, potassium, sulfur, zinc, manganese and boron. The most common deficiency was zinc; nearly 82 percent of sampled plants were short on the nutrient that aids in chlorophyll synthesis and other metabolic functions.

  • Soybeans had a sharp increase in copper deficiency. More than 65 percent of soybeans sampled lacked sufficient copper levels to meet plant health needs. This is up 24 percentage points compared to 2016. Copper is a key nutrient for protein synthesis, cell wall formation and many enzyme systems. A majority of soybean samples were also low in potassium and manganese.

  • Wheat lacked micronutrients. Copper deficiency was widespread across wheat crops last year, with nearly 85 percent of sampled plants lacking adequate concentrations of the nutrient. Limited availability of copper in wheat can lead to aborted heads and yield loss. Two other micronutrients, zinc and magnesium, were more deficient this year compared to last year.
