Brian and Darren Hefty explain Cation Exchange Capacity, and how understanding it can help you determine how much nitrogen you can apply during a side dress application.
In 1967 my dad put down all his N down as anhydrous in bed on his cotton ground. It was a cool damp yesr not very conducive for raising cotton. One farm grew cotton to height of 7 or 8 foot tall it stayed in the growth/ vegatative stage and shedded most of the blooms. Those stalks had only 2 or 3 bolls per plant... normally a good healthy stalk was about 3.5 to 4 foot tall and had 20 to 25 bolls per plant.. We planted on beds using hippers and applied anhydrous in row... harrowed the beds down and planted all P and K were dry mixed applied early spring with spreader buggies.
It all boils down to mother nature. You can have the perfect amount of nitrogen in the soil but without rain and heat from the sun...well you know what you get. So how do you moderate the nitrogen amount with the weather? The way i see it, i get lucky or i don't.

does stream baring work in corn?
I was told not to max out my N based on my Cat. Ex. Rate. Why is that?
