400 ppm avg is good goal.
Zinc could be a yield limiting on this field.
my agronomist said anything over 160-why the higher rates
I would find a new agronomist.
Why do you think your high test fields yield more?
The k uptake of 250 bpa corn is 238# or 169 ppm.
The plants are not going to find every #
Peak up take is 15#/ day.
JDplowboy What is your thought on base saturation of K?? Does it have any factor on K uptake compared to PPM?... It looks like if he did get his K levels above 400pm he would have BS K above 4%? Which would be ideal right?
