Maximising Vine Health with Targeted Post-Harvest Nutrition with Wayne Walton.
As the last bins of grapes are hauled from the rows, it’s tempting to think the season is done. But the truth is, the next season has already begun. Right now, your vines are shifting gears, moving from fruit production to nutrient storage. What you do in this short window post-harvest will influence everything from budburst to flowering and ultimately, next year’s yield.
At De Sangosse, we offer a range of organic and conventional plant nutrition products designed to replenish what your vines have used and build strong reserves for the season ahead.
PANCAL – Deep Nutrient Replenishment
Pancal is a highly effective post-harvest application. It provides a complete mix of macro and micronutrients, including:
- Calcium (Ca) – Essential for cell wall development and nutrient regulation.
- Magnesium (Mg) – Facilitates phosphorus use and amino acid metabolism.
- Nitrogen (N) – Supports protein synthesis and prepares vines for spring growth.
- Zinc (Zn) and Boron (B) – Restore trace elements used heavily in fruit production.
Pancal is ideal for restoring root-zone fertility and strengthening perennial tissue before dormancy.
BUD COMPLEX – The Complete Post-Harvest Foliar Solution
Bud Complex is a multi-nutrient blend designed to quickly replace the key elements vines need for overwintering and early spring growth:
- Nitrogen (N) – Drives protein synthesis for regrowth.
- Phosphorus (P) – Essential for cell division, energy transfer, and root development; also supports the uptake of Iron and Zinc.
- Magnesium (Mg) – A phosphorus carrier and crucial for amino acid metabolism and carbohydrate synthesis.
- Boron (B) – Supports sugar migration, auxin activity, and cell wall stability.
- Zinc (Zn) – Key to growth hormone production and protein synthesis for root and shoot development.
Bud Complex delivers these nutrients directly to the leaf, allowing rapid absorption when soil uptake is slowing down with falling temperatures.
AZOFOL NS – Boost Nitrogen with Added Magnesium & Sulphur
If your vines need a nitrogen top-up post-harvest, Azofol NS is the go-to foliar option. It delivers liquid urea enriched with:
- Slow-release Nitrogen – Provides a sustained feed without overstimulating late-season growth.
- Magnesium – Enhances photosynthesis and protein synthesis.
- Sulphur – Supports nitrogen assimilation and strengthens overall plant health.
It’s an excellent partner to Bud Complex, especially in blocks where canopy vigor or yield was high and reserves may be low.
BOROZINC – Boron & Zinc
Borozinc provides two critical trace elements that are often depleted by harvest:
- Boron – Moves sugars into storage tissues and strengthens cell walls.
- Zinc – Drives auxin synthesis, protein production, and energy conversion from sugars to starches.
Whether applied alone or alongside Bud Complex and Azofol NS, Borozinc ensures your vines have the micronutrients they need for solid winter preparation and a strong start in spring.
TERRAMIN PRO
A concentrated source of nitrogen and amino acids, promoting recovery and nutrient uptake. Improves plant resilience and supports the efficient absorption of key nutrients like phosphorus and potassium.
Start Next Season Strong
Post-harvest isn’t the end—it’s the beginning. Every product in the De Sangosse range is formulated to give your vines what they need, when they need it most. Whether you’re running a conventional or organic program, these targeted tools will help you restore nutrient balance, boost vine resilience, and lay the foundation for next season’s success.
