Thank you for your channel I am learning tons! I've been custom farming and food plotting commercially for years had no idea there was a difference between phosphate and phosphorus! I did have a question: does your CEC determine how much P and K you can apply at a time? I see you mentioned about CEC can only take so much N. So does that apply to other nutrients or is it only for N? Thank you for your time!

I have 24 ppm phosphorus and 71 ppm Zinc Can i build my phosphorus only with banding P or should broadcast? Which fertilizer is better for acidic soil, MAP or DAP?

This exact soil analysis looks to be one field split into 10 grids? or so suggests the sample ID number. My important question is at what cutoff does phosphorus levels go from very high to excessive?

Is there a formula you use to know how much phosphate you have to apply to raise your soil test results from say 20 ppm to 30 ppm?

I had a soil test done on my Bermuda pasture. It said I need nitrogen (no surprise), AND I need phosphorus. How do i get it into the ground? My guy broadcasts the fertilizer so that will put it on top. I don’t want to plow my pasture to get it down in the ground.

My question is if I'm doing a P build up on my soil, should I watch Olsen, P1, or P2 Bray? On my owned ground that has been under a build up program began with olson = 14, p1 = 11, p2 = 68. This is ph=7.8. After struggling with yields, I increased P & K to a level I think would allow good yields with a reasonable crop removal yearly fertility program in the future. Adding 100# P/acre fall 2020 (500# 18-46-0) lead to a year later Olson = 26, p1 = 24, p2=105. Should I be happy about this? It looks like 24% of the P applied went to the Olsen, the rest went to the p2. Will the p2 Bray ever be available? Tissue samples this year on average were within 7% of the expected at 10 measurements, improving 15% over previous years and yield was around 180 bpa, a 60% improvement over best previous years. Broadcast, no till and continuous corn. Thanks.

It's a sad time, to be able to make a living people will resort to their old ways when farming is able to produce more on less. Over 40% of our drinking water is threatened from farm runoff. I headr the voice from the video say something like this. Don't worry it won't go away unless you put 50 times to much, it'll just create erosion. And yes i farm and have most if my life. Some have been shown the error of of ways and changed. Those afraid of change and will not educate themselves imo are not farmers. Just destroyers . If this means nothing to you then go visit any hospital and find out what percentage of the sick got sick from what we injest. Probably will get nothing but negative feedback or else 'Imma gonna report you'. Like I say it's a choice.
