No. Follow what I asked in that first post. "What is a sufficient number at what growth stage?" Wide open question on nutrient sufficiency levels people use. This current question just leads that on with actual land grant numbers at VT-R1 for people to pick at and say if they think they are wrong, and if so, what is better.
I NEVER said anything about any application of anything at any time.
Standard information we have with RESEARCH behind for sufficiency levels has been done at the VT-R1 growth stage. I asked what people are using for "their" numbers at that stage to get to their yield goals.
I also asked if they dont use just that time frame what are other points of a corn plants life where we should be testing and what should our targets be for % or ppm of all the essential nutrients in the plant?
Everyone talked around my questions including you. I dont care what path you follow but if you cant answer a few simple questions then we did not move the needle on learning.
I’ll answer your question: nobody can give a specific % or ppm at VT/R1 because those numbers don’t exist. Ratios and base saturation charts make great sales tools, but they’re almost meaningless to the plant and they don’t predict yield. That’s why nobody in the last thread gave you a number, not because they were evasive, but because the biology doesn’t work the way you’re framing it.
It's almost like your framing a number you know doesn't exist, into an argument nobody is having to prove a point more than let's have a discussion.
Now I wait for you to answer my questions |
