Case Study: Fulvic Gold Lifts Grape Yields by 25% in Victorian Vineyard
📍 Location: Mallee District, Victoria, Australia
🍇 Crop: Sultana Grapes (Irrigated Vineyard)
🌱 Soil Type: Sandy Loam | pH: 5.5
🗓 Trial Duration: Multi-year (3 reporting seasons)
Background
In Victoria’s Mallee region, where rainfall is scarce and soil fertility is challenged, vineyard managers are under pressure to maximise both water use efficiency and grape yield. A sultana grape grower initiated a cost-benefit trial using Fulvic Gold, aiming to improve productivity without increasing synthetic inputs.
PLEASE NOTE: The results presented in this case study were based on trials using a solid-form humate. Fulvic Gold is a liquid formulation derived from the same humate source, optimized to deliver high concentrations of bio-available fulvic acids for efficient uptake and ease of use. While formulation differs, the underlying active compounds and source material remain the same.
Trial Design
The trial was structured around two methods of Fulvic Gold application:
- Surface Application: Applied directly along vine rows, then incorporated into the soil
- Inter-row Application: Applied in bands down the centre of the inter-row zone
Each method was tested across 15 vineyard rows at a rate of 3 m³/ha. A separate section of the vineyard—following standard commercial practice—served as the control.
Key Results
🍇 Yield per Row
- Fulvic Gold (both methods): 1,250 kg per row
-
Control: 1,000 kg per row
➡️ +25% increase in grape yield
🌿 Plant Health Indicators
- Treated vines showed:
- Increased cane growth
- More vigorous foliage
- Visibly larger grape bunches
📈 Sustained Improvement
- The yield advantage persisted over three growing seasons, validating Fulvic Gold's long-term soil conditioning effect.
Conclusions
- Fulvic Gold significantly boosted yield by 25%
- Visual improvements included larger bunch size and denser canopy
- Both application methods were equally effective, giving flexibility to growers
- A 3 m³/ha application rate was confirmed to be optimal under these vineyard conditions
This trial proves that even in sandy soils with minimal rainfall, Fulvic Gold can deliver substantial, sustained gains in yield and vine health.
