Polymex

Polymex is a fertiliser additive that encourages phosphate uptake in young plants, helping crops establish longer and more advanced root systems more quickly.

Polymex works by unlocking the phosphate in soil fertilisers so it is available to crops for longer. Water soluble phosphate is essential to the health of young plants, but phosphate rapidly becomes insoluble in UK soil. Adding Polymex to liquid or granular fertiliser significantly slows that process, helping to produce healthier, more disease resistant crops.

Crops
Polymex works by unlocking the phosphate in soil fertilisers so it is available to crops for longer. Water soluble phosphate is essential to the health of young plants, but phosphate rapidly becomes insoluble in UK soil. Adding Polymex to liquid or granular fertiliser significantly slows that process, helping to produce healthier, more disease resistant crops.

Use
Use Polymex as a fertiliser additive to help your crops get the phosphate they need for healthy growth. 

Pack Sizes
20, 1000 litres, or pre-mixed with fertiliser

Composition
Thermal polyaspartate

 

Water soluble phosphate is vital for plants. It helps rapid establishment of crops and is an essential component of the energy cycle within the plant. It also helps produce healthy root systems that are more resistant to diseases.

Phosphate fertilisers
After application to soils in the UK, phosphate fertilisers rapidly complex with cations such as calcium and magnesium to form insoluble compounds. This significantly reduces the availability of both the phosphate and calcium or magnesium to plants.
The speed at which this process takes place can be rapid, with most of the phosphate from an application to warm aerated soils becoming immobilised within a period of a few hours to a few days. Once immobilised,
the phosphate is effectively unavailable to the plant until the compound is broken down by microbes or plant root exudates in the soil.

Polymex – Function
Polymex is a complex biodegradable long-chain polymer. It protects phosphate from becoming immobilised in the soil and ensures that the water soluble phosphate fertiliser applied to responsive crops remains soluble for longer. As a result of the greater availability of phosphate young plants are able to establish a longer and more extensive root system more quickly. Trials have shown that not only are the root systems more advanced, but also the roots have a significantly higher level of root hairs, which assimilate higher levels of nutrients as a result.

 

Use Polymex on high pH or calcareous soils when phosphate lockup is known to occur or is suspected. Best results are achieved when placed in mix with liquid phosphate fertiliser.

Apply 1-5 l/ha.

Liquid Fertiliser: Add half of the fertiliser to the spray tank, add the required amount of Polymex whilst agitating
then add the remaining fertiliser. Maintain agitation whilst applying.

Granular Fertiliser: Apply before application of granular fertiliser using spray nozzles. Add half of the water to the spray tank, add the required amount of Polymex whilst agitating, and then add the remaining water. Total spray volume should be a minimum of 200 l/ha. Maintain agitation whilst spraying.

 

¹ For best results with Polymex apply through a placement applicator in mix with liquid starter fertiliser (such as 7-20-0) at time of planting/drilling.

Polymex is physically compatible with the full range of OMEX clear solution fertilisers. To ensure complete mixing with OMEX suspension fertilisers Polymex should be mixed during production by OMEX.

 

A phosphate stabiliser used to extend the availability of phosphate in the soil, reducing imobilisation and loss of fertiliser efficiency.

Polymex is based on thermal poly aspartate and forms a complex with phosphate in the soil to protect it from becoming insoluble and unavailable to plant roots. It is particularly effective during turf establishment and in situations where a phosphate deficiency has been identified.

Polymex can be tank-mixed with any of the OMEX phosphate products or simply sprayed onto soil or turf prior to spreading solid fertiliser.

Application of Polymex on its own can help increase the availability of phosphate that is already present in the root zone, without the need to apply more phosphate fertiliser. 

When to Use How Much to Use Comments
With phosphate fertilliser 250ml/green, 5 litres/ha Can also be used to increase soil P availability
