Key reasons for the use of (Fulvic Acid)
Fulvic acid is derived from the breakdown of vegetative material. When applied to the soil it behaves in a similar fashion to Auxins (plant growth hormones) and increases development of the root. In a replicated turf trial in WA the addition of GC50plus increased total root surface area around 40% over untreated. This leads to improved uptake of water, nutrients and supports greater development of root and tuber set.
The presence of Fulvic acid in the soil supports increased biological activity but specifically the growth of Vesicular Arbuscular Micorrhiza (VAM). VAM have an important function in increasing or extending the ability of the turf grass root system to uptake Phosphorus and Zinc from the soil solution. VAM also has a role in the transfer of sugars.
The Turf Science GC50 why use it?
This product is our standard polyacrylamide formulation. It is suitable as an additive for application through any irrigation system. The primary function of the GC50 formulation is to improve water use efficiency. While results will vary given different soil types, the expectation is that efficiency improvements of 30% or better can be achieved. This efficiency can be expressed as either less water required per irrigation event or extending the period between irrigations. Slowing the movement of water through a soil profile has exhibited positive effects in improving turf grass nutrient uptake in combination with improved water use.
GC50 formulation is compatible with liquid fertilizers. The application of our liquids stimulates microbial activity and as a food source and they assist with the breakdown of the product in the soil.
Formulated to overcome hydrophobic (non-wetting) soils. Such as sandy soils.
Polyacrylamides have a capacity to overcome soil surface tension issues in hydrophobic soils. Where soils are extremely hydrophobic GC50ss formulation should be used. This formulation contains a small amount of high quality wetting agent to assist in the breakdown of severe surface tension. Unlike general wetting agents the GC50ss formulation will also hold water in the profile to improve water use efficiency.
