Under the bonnet.
You know your tractor down to the horsepower. Steve wants growers to know their crop the same way.
Lift the hood
Growers can tell you every figure on their tractor. Then they’ll put a program on the crop without asking what it does. This episode lifts the hood on the plant itself: photosynthesis, the engine that pays for everything else.
And one part of it Steve wants every grower to remember: manganese, the hidden engine that keeps photosynthesis running.
A moving picture
One sap test is a snapshot. A run of them across the season shows which way the plant is heading, often early enough to do something about it.
Then there’s where to look. Some minerals move around the plant and some stay put, so a shortage shows up on old leaves or on new growth depending on which one it is.
