Some of our Bestsellers:

KingPhos

KingPhos

Reduce waste with granulated dicalcic phosphate

KingPhos ranks highly for nutrient efficiency and safe, accurate application. It releases its phosphates in a controlled way while lifting soil pH. So it’s kind on soil biology and the environment too.

Learn more about the advantages of applying KingPhos.

RePlenish

RePlenish

Save money while replenishing your phosphates

Replenish is a high-analysis dicalcic phosphate. It’s not soluble like Super, and you can apply it at rates that are 20-30% less. It’s also proven to reduce phosphate losses. That’s a winning formula to reduce wastage to waterways and your pocket.

Tell me more about RePlenish.

SeaPhos

SeaPhos

Opt for a dicalcic phosphate that boosts soil biology

SeaPhos is no ordinary phosphate fertiliser. It has all the benefits of dicalcic phosphate and natural seaweed biostimulants blended together. Soil health and biology, plant health and growth are optimised.

Find out why SeaPhos is such an innovative product.

44 Magnum

44 Magnum

Take control of your nitrogen use

Unlike many common nitrogen fertilisers, 44 Magnum is designed to release its nitrogen in a controlled way over a much longer time. It has added sulphur for immediate growth response. Apply it once and you’re done!

Learn more about how 44 Magnum is perfect for wet and busy times.

N Smart

N Smart

Protect the environment with a smarter nitrogen fertiliser

N Smart is a source of polymer-coated nitrogen, designed to reduce volatilisation and leaching. The outcome is that less nutrient is lost so you get a greater yield from each kg of nitrogen applied. Now that’s nutrient efficient!

Check out more benefits of using N Smart.

N-durance

N-durance

Optimise your N-Cap allowance

Because N-durance contains both N-inhibited and polymer-coated nitrogen, it tackles wastage by slow and controlled release of its nutrients. So, reduced losses to waterways, and less needed to achieve the same growth. An N fertiliser that stays the distance!

See more about how N-durance is nutrient efficient.

Protamin® N13

Protamin® N13

Prioritise soil health with natural nitrogen

Finally, a BioGro-approved, organic source of nitrogen! No worries with soil health because Protamin® N13 has added biostimulants and a fast, medium, and slow release of nutrients. That’s also a tick for the environment.

Explore the benefits of Protamin® N13.

Phosta K

Phosta K

Choose a BioGro approved, natural potash

Phosta K is made from 100% plant-based material sourced from sugar cane processing by-products. It’s less soluble than other potash fertilisers so slower to break-down. Another winner if you want to support soil health.

Read more about how Phosta K can work for you.

Double S

Double S

Get granulated high-analysis sulphur for year-round growth

Double S contains two types of sulphur in the one product for a regular and continuous supply of sulphur over an entire season. You won’t grow healthy pasture and crops without sulphur.

Read how sulphur and Double S can boost growth.
