Greg and Merv Keating Final Report

Region: Mackay

Who: Greg and Merv Keating

Location: Plane Creek

To evaluate the application of reduced nutrients on old ratoons, with a low yield potential, that will be ploughed out

Older cane ratoons have lower expected yields compared to younger ratoons. Each time the crop is harvested, crop vigour is lost due to age and harvester damage. Having a lower yield potential provides the opportunity to lower the amount of nutrients applied.

This trial will determine whether applying lower nutrient rates will result in improved nutrient use efficiency, reduced risk of nutrient run off, while still maintaining yields.
