Balanced Growth for Strong Sweet Potato Establishment

Organifer Sweet Potato Liquid Fertiliser is formulated to support healthy, balanced growth in sweet potato (Ipomoea batatas), a vigorous root crop from the morning glory family. Sweet potatoes require steady nutrition early in the season to establish strong vines and an efficient root system without excessive leaf growth. The 2-1-8 formulation provides controlled nitrogen with elevated potassium to guide plants toward productive storage root development.

Optimised Root Formation and Bulking

Sweet potatoes are grown for their nutrient-rich storage roots, which require high potassium availability during bulking stages. This liquid fertiliser supports uniform root initiation and encourages consistent enlargement of the tubers. Potassium improves carbohydrate transport and storage within the roots, helping produce well-shaped, dense sweet potatoes with improved nutritional quality and market value.

Improved Nutrient Uptake and Soil Efficiency

Organifer Sweet Potato Liquid Fertiliser enhances nutrient mobility in the soil and improves uptake efficiency throughout the growing cycle. The liquid formulation ensures fast availability of nutrients, while organic components support soil activity and root interaction. Amino acids stimulate metabolic processes in the plant, helping sweet potatoes utilise nutrients more efficiently during both vegetative growth and root expansion.

Strong Vine Growth Without Excessive Leafiness

Sweet potatoes naturally produce long, spreading vines that support photosynthesis and energy transfer to the roots. This liquid fertiliser promotes healthy vine development without encouraging excessive nitrogen-driven leaf growth that can reduce root yield. Balanced nutrition helps maintain an ideal leaf-to-root ratio, ensuring energy is directed toward storage root formation rather than excessive foliage.

Stress Resistance and Consistent Yield Formation

Sweet potatoes are sensitive to moisture stress and nutrient imbalance during root development. Organifer Sweet Potato Liquid Fertiliser supports internal water regulation and strengthens plant resilience under warm growing conditions. Potassium improves stress tolerance, while amino acids support recovery from temporary drought, heat, or transplant stress, contributing to more consistent yields.

Suitable for All Sweet Potato Varieties and Growing Systems

This sweet potato liquid fertiliser is suitable for orange-, white-, and purple-fleshed sweet potato varieties grown in open fields, raised beds, or professional vegetable production systems. The vinasse-free formulation ensures clean feeding, while amino acids support uniform growth across different soil types and climates.

Dosage

Number of applications: 3–5
Start: At early growth

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

Maintain consistent soil moisture during root development to avoid irregular tuber formation. Ensure adequate calcium and magnesium availability to support strong cell structure and root quality. Avoid high nitrogen inputs later in the cycle, as this can reduce root bulking and promote excessive vine growth. Provide good weed control early in the season so young plants are not outcompeted. Once root bulking begins, avoid disturbing vines to prevent damage to developing sweet potatoes.

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.
