Amvista Onyx Granular Fertiliser 13-1-2 (25kg)

Onyx Granular fertiliser is an organic and plant derived source of nitrogen, trace elements and amino acids. These help to provide the required nutrition for growth and root development. Along with this there is also an organic biostimulant effect that aids with germination, grass establishment and resistance to environmental stressors that can impact healthy growth.

The biostimulants help specifically with the plants ability to cope with drought, excessive heat and salinity which would normally cause them to be overwhelmed and fall into dormancy and take damage. They will also encourage the plant to keep growing and simulate its natural stress response, keeping it greener for longer.

ONYX Granular can be applied all year round to boost plant health and condition ahead of stressful periods.

We recommend all growers undertake a Soil Analysis, to measure the exact nutrient content of the soil. This inexpensive, mail-order soil sample test allows our qualified experts to highlight any nutrient over or under supply that limits plant growth or animal health. We often recommend the use of less fertiliser than expected, but instead target a missing nutrient that limits the plants potential.
