Agri-Zinc Chelate Liquid Organic Fertiliser 20L

Agri-Zinc chelate liquid organic fertiliser for correcting zinc deficiency and supporting crop growth

Agri-Zinc chelate liquid organic fertiliser supplies readily plant-available zinc, combined with fulvic acid and earthworm exudate. Fulvic acid acts as a natural chelator, helping zinc absorption, while the earthworm exudate contributes micro-organisms that support plant growth. This targeted zinc feed helps correct deficiencies and maintain adequate zinc levels during active growth, with crop-specific application guidance for grains, legumes, vegetables, fruit trees and vineyards.

Features

• Targeted zinc nutrition: Helps alleviate zinc deficiency and maintain adequate zinc levels for productive crop growth.
• Natural chelation: Fulvic acid supports the availability and absorption of zinc.
• Biological support: Earthworm exudate supplies micro-organisms that complement the formulation.
• Growth-stage support: Supports zinc nutrition during rapid vegetative growth and key reproductive stages.
• Flexible application: Crop-specific seed, soil and foliar applications suit different growing programmes.
