Innovative Turf Grass Seed Treatment


To maximise plant development all Johnsons seed mixtures are GroMax coated as standard!


  • Improves establishment

  • Stimulates root growth

  • Makes for greater tolerance to stress

  • Enhances water and nutrient uptake

GroMax is a dry formulation of biostimulants consisting of natural humates and humic acids, seaweed extract, a proprietary blend of
natural sugars (sucrose), Vitamins (B complex and K), soluble potash and buffering agents. This coating assists the seedling’s ability to
take advantage of the soil’s own inherent reserves of nutrient by stimulating the soil’s microflora, resulting in improved root growth
and establishment. It is compatible with most micro-nutrients, fertilisers and pesticides.

Humic Acids: Rich in auxin type substances to enhance antioxidant synthesis. This aids plant metabolism under stress conditions and gives a high carbon food
source for soil micro-organisms. In turn this improves the permeability of cell wall membranes in roots to allow rapid absorption of essential nutrients.

Seaweed Extract: Contains high levels of cytokinins to promote cell division and lateral root growth, but delaying the ageing process of plant tissue. In
addition root growth is stimulated after damage by disease or root feeding insects, or stress caused by temperature, water or salt imbalance.
B-Complex and K Vitamins: These act as important catalysts to enhance and drive plant metabolism, with vitamin B1 giving help to rooting.

Amino Acids: The building blocks of proteins known to be essential for plant growth and metabolism.

Potassium: Plays a vital role in disease resistance and overall hardiness of grass plants.

Sucrose: Serves as a high energy food source for plant and soil microorganisms.
