Addressing the burning issues in Margaret River’s parched vineyards with plant nutrition

Mike Sleegers, Cowaramup Agencies, caught up with the Vicentia/Agrichem team to talk with growers about solving some of the issues our Margaret River region’s vines are facing. Together they have identified real scope for using these products to improve vine physiology post harvest and to provide excellent pre-flowering nutrition. 

Mike talks to Vicentia about nutrition and technology that can:
1. Improve fruitfulness
2. Improve root systems 
3. Address soil compaction, and
4. Deal with problems with water.

They also looked at Vicentia trial results from a Margaret River vineyard.


This trial was conducted at a select vineyard in Margaret River on Blocks D6 and D7 (variety – Shiraz) using the Vicentia technology.

The trial yielded positive results in terms of produce which was 49% higher in the treated plot as compared to the control. The bulk density was also reduced in the treated plot which is directly proportional to soil compaction.

The white feeder roots in the treated block are an indication of lower soil compaction and more area for the roots to penetrate, thus higher nutrient availability to plants.

The heat stress management was found to be better in the treated block which shows that a better nutritional program can help the vines cope with adverse weather conditions.

Another round of one-on-one meetings in planned for late May 2024. If solving some or all of the issues raised here is important to you, get in touch with Mike: m 0436 128 112 e
