AlmondBeat 9: Avoid barking with this irrigation formula‏

Updated: Aug 3, 2020

Harvest is around the corner and soon slow-motion videos of shakers working in orchards will flood your social feed. These awe-inspiring shots sometimes come with a price - Barking (when the bark tears away from the tree). The main reason for it is that trees are too "wet" carrying excess moisture in their trunks which makes them susceptible to damage during shaking.

A window of opportunity

The solution and common practice many growers in the Valley are using is to dry out their trees before shaking them.

But exactly how much time and how much stress should growers apply without affecting the tree's future health and productivity? When is the optimal time to cut irrigation and push the trees into negative growth and how much time should they stay thirsty?

This is where millions of plant pulses that we collect each day together with field feedback from our growers - came in handy. 

By cross-checking direct data from the blocks (trees' trunk size and water demand, actual water delivery, and block's stress history) with information supplied by our customers (Actual barking rates in their fields) we have identified an irrigation practice that can significantly reduce this unwanted phenomenon.

We found out that avoiding positive growth 3 days before shaking significantly reduces shaker damage and helps in optimizing this stage. Cutting irrigation, inducing stress (red plant status), and stopping trees' growth 3 days before shaking can lead to "zero barking" and better rate of nut removal.
