Vineyard Guide: Get the most out of your grape fertilizer

Experienced grape growers know that precise nutrition management is essential to optimize vine performance and achieve premium fruit quality.
Haifa’s specialized nutrition solutions are designed to unlock the full potential of vineyards, whether for wine or table grapes. Powered by premium products, deep agronomic expertise, and advanced technologies, Haifa’s Nutri Haitech™ approach delivers precision nutrition exactly when and where grapevines need it. The results: improved berry size and sugar content, enhanced color and cluster uniformity, extended shelf life, and higher profitability. With well-timed, balanced nutrition, growers can boost yields and fruit class – while maximizing nutrient use efficiency and reducing environmental impact.

Highlights for your GRAPE crop nutrition

	Vegetative growth Foliar applications of NPK+micro are recommended, to match demands at this stage while uptake by roots is still limited. Application of humic substances improves soil properties and root activity.
	Pre-flowering Adequate boron supply in this stage is necessary to avoid Millerandage, which might lead to uneven berry size and ripening.
	Flowering and fruit set These are stages of peak nitrogen demand. To ensure efficient uptake it is recommended to supply high nitrate.
	Berry growth Addition of micronutrients at this stage is essential for optimal accumulation of sugars and anthocyanins in the growing berries.
	Veraison Foliar applications of potassium are recommended, to match high demands at this stage.
	Berry maturation Calcium is required to protect the fruit and to improve its quality. Even when not manifested on leaves, calcium deficiency might result in berry cracking, berry dropping and grain rot. In wine grapes, leaf analysis provides indication of the required post-harvest fertilizer application rates.
	Shoot maturation and leaves fall Post-harvest fertilization creates nutrient reservoirs for the next season. Application of humic acids improves soil properties and root activity

Salinity

Grape vines are moderately-sensitive to salinity, with potential of 10% yield loss at EC of 2.5 dS/m. Low salinity irrigation is critical in both saline and non-saline soils. Make sure to apply fertilizers with low salt index and minimal chloride & sodium content.
