Plant Food – Liquid NPK Concentrate Range | The Olive Centre
Rapidly absorbed NPK solution for early growth, fruit set, and sustained plant vigour.
AgroBest Plant Food is a premium liquid NPK concentrate range formulated for rapid absorption and superior plant nutrition.
This clear solution of Nitrogen, Phosphorus, and Potassium supports vigorous growth from early vegetative stages through to flowering and fruit filling.
Manufactured using high-purity ingredients, including 100% orthophosphoric acid and low-biuret nitrogen, it ensures optimal plant availability and mobility.
Up to 80% of nutrients are absorbed within one hour of application, promoting strong root development and enhanced flowering even under stress conditions.
Ideal for broadacre crops, orchards, and vegetables, Plant Food provides complete, balanced nutrition across the growing season.
Uses
Plant Food delivers a balanced supply of essential nutrients for seedling establishment, vegetative growth, and fruit development.
It enhances cell division, carbohydrate production, and nutrient translocation, supporting stronger plants and improved fruit yield and colour.
Suitable for use across horticulture, field crops, turf, and orchard systems, it can be applied via foliar spray or fertigation for maximum efficiency and flexibility.

Its rapid absorption and ultra-pure ingredients make it one of the most efficient liquid fertilisers for professional growers.
By maintaining strong plant growth through all development stages, Plant Food supports sustainable productivity and maximum crop performance.
Frequently Asked Questions
Plant Food by AgroBest is a rapidly absorbed clear NPK solution formulated with high-purity ingredients and orthophosphoric acid, which provides 98% phosphorus availability to the plant.
Unlike generic NPK fertilisers, it uses low-biuret nitrogen sources and precise NPK ratios for different crop stages:
NPK 20-4-6 – early vegetative growth and nitrogen-demanding crops.
NPK 13-7-11 – balanced nutrition for mid-season growth and canopy expansion.
NPK 3-12-20 – fruit-filling and ripening phase, enhancing flavour, colour, and sugar content.
This staged nutrient approach ensures sustained plant performance and high nutrient uptake efficiency. Tests show that up to 80% of nutrients are absorbed within one hour of foliar spraying under normal conditions.
Plant Food can be applied via foliar spray, aerial, sprinkler, or fertigation systems, making it highly versatile.
For foliar feeding, dilute 1:50 to 1:200 depending on crop type and growth stage.
For irrigation or soil application, use higher rates for better root-zone penetration.
Apply every 3–4 weeks for ongoing nutrient supply, or more frequently during peak growth periods.
For optimum results:
Apply early morning or late afternoon when leaf stomata are open.
Maintain good spray coverage over leaves and fruit.
Avoid application under high heat or water stress.
Including AgroBest AgroChelate (1:1000) and Spraytech Oil in the tank mix can improve nutrient uptake and rainfastness.
Yes — Plant Food is classified as non-hazardous under GHS and is non-combustible according to the Safety Data Sheet.
It is biodegradable, low-toxicity, and safe for use in all cropping systems when applied correctly.
Key safety highlights include:
No poison schedule classification and no specific antidote required.
Low skin and eye irritation potential — standard protective gear (gloves, glasses) is sufficient.
Non-flammable and stable under normal temperature conditions.
However, like all fertilisers, it should be stored in a cool, dry area away from incompatible materials (e.g., strong acids, oxidisers, or ammonia) and kept out of waterways to avoid nutrient runoff into aquatic environments.
