Yates FlowTrace
Yates Flowtrace is a free flowing, finely ground, trace element mixture designed for incorporating into potting media before potting. It offers a one-shot method of delivering all the trace elements needed for typical Australian potting media. The balance between the trace elements in Yates Flowtrace is based on extensive research by Australian plant nutrition authority Kevin Handreck.
Suitable for: Potting media, Compost mixes
- A complete trace element mix providing all the TE needed for typical Australian potting media. No additional TE required.
- Designed specifically for Australian potting media, whose main components are pine bark and woody composts.
- Formulation is based on extensive research by Australian plant nutrition authority Kevin Handreck.
- Contains a high iron content which is most commonly lacking in wood based potting mixes.
- Finely ground and easy flowing to spread quickly throughout the potting medium into which it is incorporated.
- Added zeolite improves flowability and prevents caking or setting solid.
- Enables the vast majority of Australian potting media to deliver the optimum range of plant-available trace elements, as per the Australian Standard for Potting Mixes.
- At the recommended application rate, zinc and boron will be supplied in adequate amounts. However, halving or doubling the rate will not cause deficiency or toxicity.
Iron (Fe) as Ferrous sulfate 24%
Sulfur (S) as Sulfate 14%
Copper (Cu) as Copper sulfate 0.75%
Manganese (Mn) as Manganese sulfate 0.5%
Zinc (Zn) as Zinc sulfate 0.2%
Molybdenum (Mo) as Sodium molybdenum 0.04%
Boron (B) as Sodium borate 0.033%
Note: The manganese content is intentionally low because this trace element is usually already present in adequate, or near-adequate, amounts in pine bark and other organic components.
Once added to the potting medium the trace elements in Yates Flowtrace will dissolve in water. The iron, copper, zinc and manganese will then react with phenols and humus to produce chelated forms. These are held firmly on, and within, the particles of bark and wood throughout the medium. This even distribution means they are readily accessible by plant roots throughout the medium.
Yates Flowtrace is only recommended for addition to a potting medium or its components before potting. It may be added to bark and other wood wastes before these are composted or to the mixture of components as they are being blended into a potting medium.
Application Type
- Yates Flowtrace as sole source of trace elements: Incorporate at 1 kg/m3
- If a component already has iron sulfate added (e.g. before composting): Can be incorporated at reduced rate of 0.5 kg/m3
- For potting medium with high proportion of fine humified organic matter: Flowtrace rate can be increased to 1.5 kg/m3
The addition of Yates Flowtrace™ at recommended rates will provide plant available trace elements in bark and wood based potting mixes within optimum ranges. Refer to the Australian Standard for Potting Mixes (AS 3743) for further information relating to minimum and maximum levels.
Yates Flowtrace should only be added to potting mixes and their components before potting. It can also be added to bark and other wood wastes before composting or as they are blended into a potting medium.
The iron, copper and zinc will remain in plant-available form for many years, provided the pH of the medium stays within pH 5 to 6.4. An increase above pH 6.4 may reduce supply of these trace elements to some plants. There is no need to repeatedly add more of these trace elements for most plants. Zinc for citrus is a notable exception.
The added molybdenum will also remain available for many years.
Under non-leaching conditions, the added manganese and boron will also remain available for several years. If pots are subject to excessive irrigation, both trace elements will slowly leach from the potting media. However, even in heavy leaching situations, the amounts of manganese and boron added by Yates Flowtrace will last for one year.
