It is very common for the combination of those two things to reduce nitrogen applications by thirty to forty percent in the first year, uh, and without a yield drag or yield loss

lossHey, John.

Can I step in here for a second? Um, so same question but with uh, P-K and so on.
55:18
There's huge disconnect between soil fertility and a sap sample from a P and K standpoint, and I see... um, for my own example like my part per million on potassium was 240 to 300 part per million.
55:32
Phosphorus is in the upper 20s to mid-30s yet at times my sap samples are terrible or especially R2 soybeans this year.
55:42
My sulfur is almost non-existent, my potassium is almost non-existent though my soul fertility is good.
55:48
Um, I have noticed the chloride in the sap sample being high.

So, um, it did, it did tend me to con-at least consider the possibility that at least in some high humidity environments, a, an evening application might not be truly essential to get the best results.
