Determination of the petiole nitrate nitrogen concentration (PNN) in the youngest fully expanded leaf (YFEL) of cotton is a useful indicator of plant nitrogen status.

This paper address why there are differences in the soils of the lower Namoi Valley.

This project was prompted by disappointingly low cotton yields at Emerald and other Central Queensland centres.

On many occasions, we saw some parts of our farm, produce this 3 bale yield, but not over a whole field. One corner ,or one side, or a top or bottom end, but not all over.
