About Verigrow Australia

Verigrow is owned by Veratin Limited, an Australian publicly listed company (NSX:VTN) that manufacture innovative, sustainable and environmentally friendly products from low-grade wool that is often discarded.

Verigrow is our plant and soil health nutrition brand, which include liquid fertilisers and soil improvers, soil wetters and biodegradable plant pots. Verigrow Fertiliser and Soil Improver is a revolution in plant nutrition. Developed by PhD Chemist, Dr Ramiz Boulos, it is an innovative all-purpose fertiliser and soil improver all-in-one, derived from low grade wool and rich in amino acids: the building blocks of plant growth. Wool is a sustainable resource and more than 75% of wool is made of amino acids. It contains an organic (from amino acids) and an inorganic source of nitrogen (12% w/v total N). The inorganic nitrogen provides an immediate source of nitrogen while the organic nitrogen provides a slow release and longer lasting effect. You can use Verigrow Fertiliser and Soil Improver on anything and everything including lawn, fruit trees, vegetables, flowers, natives, herbs, broadacre crops and more.

Benefits of amino acids

Amino acids are the building blocks of life. The benefits of amino acids for plants are numerous and have been studied by several research groups over the years. The summary below is extracted from peer-reviewed scientific articles but is by no means comprehensive. If you would like to learn more, we have included references at the bottom of the page.

Amino acids help plants combat stress, improve flowering, increase root mass, activate natural defence mechanisms in plants, and enhance photosynthesis by increasing the chlorophyll concentration. They also promote nutrient absorption and stimulate the essential metabolic activities in the plant. Most amino acids are also charged enabling them to attract water molecules and therefore help with water retention.

Amino acids are valuable feedstock for microorganism and are biodegradable via natural pathways. They improve the beneficial microflora in various ways, such as, by strengthening the outer walls, allowing them to withstand harsher conditions. Happier, stronger microbial colonies help produce better nutrient uptake, as well as a more extensive and healthier root system that can fight diseases and maintain effectiveness in adverse environmental conditions.

It takes energy for plants to synthesise the amino acids required to create those cells using primarily nitrogen, phosphorus and potassium (NPK) from fertilisers. This happens either directly by incorporating such elements in the amino acid structure (e.g. nitrogen) or indirectly by exploiting such elements to activate enzymes (e.g. potassium) or build the energy currency of cells (e.g. phosphorus). The presence of amino acids in Verigrow Fertiliser and Soil Improver therefore negates the need for high levels of NPK fertilisers and reduction in inputs of 25% – 30% can be achieved. Providing plants with supplementary amino acids save plants energy, which they can utilise elsewhere. This helps maintain not only vigorous growth but pest and disease resistance as well.

Complimentary products

Verigrow Fertiliser and Soil Improver is primarily a nitrogen-based product that is amino-acid rich, reducing but not eliminating the need for phosphorus and potassium. Verigrow Supplement is an all-purpose product containing a balanced blend of macro (except phosphorus) and micro nutrients, and trace elements. The lack of phosphorus in the product makes it suitable for all plants including natives. For non-native plants that need phosphorus to grow and flourish,  Verigrow Phosphorus provides a healthy dose of the element. The two products complement Verigrow Liquid Fertiliser and Soil Improver providing a complete nutritional solution for your plants’ needs that is flexible.

If you are looking for some help with hydrophobic soils, try our all-purpose Verigrow Soil Wetter. It comes with specialty non-ionic based surfactant to facilitate rapid wetting and a sugar-based humectant for absorption. It is compatible with our range of fertilisers and soil improvers and can be used with our biodegradable Verigrow Pot.

Independent studies

An independent trial has shown that Verigrow Fertiliser and Soil Improver is significantly better than Seasol in improving various plant health parameters. These parameters include biomass, plant height, root mass and Normalized Difference Vegetation Index (NDVI) (an indicator of the vegetation greenness). The study found Verigrow Fertiliser and Soil Improver was 2 to 5 times better in every parameter measured.

In independent broadacre trials on wheat, results have shown that 1 unit of nitrogen from Verigrow Fertiliser and Soil Improver is equivalent to 3.5 units of nitrogen from Flexi-N and urea. These results support the lower environmental footprint of Verigrow Fertiliser and Soil Improver without compromising performance. Similar results were obtained in an independent turf trial that have demonstrated the low nitrogen input in Verigrow Fertiliser and Soil Improver produces a significant result.
