Organic Biostimulant Liquid Fertiliser

Onyx liquid is an organic biostimulant fertiliser. A rich black liquid, made from plant-based materials; Onyx provides high-levels of amino acids, plus nitrogen and potassium as well as phosphorous, trace elements and carbohydrates.


Onyx provides not only the nutrition for growth and root development, but also provides a biostimulant effect to encourage germination, establishment and resistance to environmental stress factors.


Packed with a natural cocktail of biostimulant substances it boosts the plants ability to cope with stressful conditions including drought, heat and salinity. Under stressful conditions the plant’s stress-response mechanisms can become overwhelmed, leading to dormancy and damage. The biostimulant effect can encourage the plant to keep growing and stimulates the natural stress-response, keeping the sward greener and healthier for longer.


Frequent, and small applications are recommended, helping develop a strong root system and ecosystem in the rhizosphere and keeping the plants fighting-fit ahead of any periods of stressful conditions.


The carbohydrates and organic substances in Onyx can also stimulate beneficial micro-organisms in the soil generating further benefits for soil structure and nutrient availability. Onyx can be applied all year round to boost plant health and condition ahead of stressful periods.
