Tissue Sample Results in Iowa

As tissue sampling continues, results from the entire state of Iowa are compared to the national average and have been compiled as far as stage V 11 in corn.  Information was broken down to each nutrient.

The graph shown is for zinc.  Looking at the major nutrients, Nitrogen and Phosphorous in Iowa results show higher amounts of both nutrients in the plant.  Potassium appeared to be near national average.

Data for N-P-K could change greatly in upcoming results as major uptake is started at the later stages.

For Manganese and Zinc, results show Iowa being deficient and below the national average once you get past the V7 stage.
