Enhanced Growth & Bulb Development for Onions

Organifer Onion Liquid Fertiliser provides balanced, crop-specific nutrition to support the development of healthy, firm bulbs in Allium cepa. Onions require steady moisture, moderate nutrients, and controlled nitrogen levels to form uniform, dense bulbs with good skin quality. The 2-1-8 formulation prioritises potassium, ensuring stronger cell structure, improved bulb firmness, and better tolerance to environmental stress throughout the growing cycle.

Improved Nutrient Uptake, Root Health & Early Establishment

Onions have shallow, fine roots that depend on consistent moisture and gentle nutrient availability. Organifer’s organic liquid formulation enhances microbial activity and soil structure, improving nutrient mobility around the root zone. The inclusion of amino acids supports early root establishment and boosts metabolic efficiency, helping onions transition smoothly from vegetative growth into bulb initiation.

Supports Bulb Firmness, Storage Life & Skin Quality

Potassium and calcium are essential for forming tight, resilient onion skins and preventing storage-related issues. This fertiliser strengthens bulb structure while reducing the risk of splitting, soft spots, and premature sprouting. Magnesium availability improves green leaf health, supporting photosynthesis and ensuring the plant accumulates enough energy for bulb expansion and flavour development.

Dosage

Number of applications: 3–5

Foliar spraying: 3–7 ml per 1 litre of water
Fertigation: 1–2 ml per 1 litre of water
Standard dose: 5–9 L per ha

Keep soil moisture consistent during bulb formation, as fluctuations cause misshapen bulbs and reduced storage quality. Provide adequate calcium and magnesium to strengthen cell walls and improve firmness. Avoid excessive nitrogen late in the cycle to prevent soft bulbs and delayed maturity. Stop irrigation 2–3 weeks before harvest to help bulbs cure properly, and maintain weed-free rows early in the season, as onions compete poorly with weeds.

Storage

When stored under stable, frost-free conditions and protected from direct sunlight, this liquid fertiliser maintains its quality for an extended period. Closed containers preserve the formulation effectively, while any diluted solution should be used promptly to ensure optimal performance and purity.
