Every fertiliser grade supplied by Natures Fertilizer, laid out side by side so you can compare analyses without opening a page for each one. 114 compound, blended and water-soluble grades plus the straights they are built from.

“Units” is the total of the three numbers — the nutrient you are paying freight on out of every 100 kg. “Character” and “Suits” are derived from the ratio itself, not from a recommendation for your paddock: set application rates against a current soil test and confirm them with a qualified agronomist.

High-Tower Compound Grades

High-tower granulation sprays molten fertiliser from the top of a tower and lets it solidify as it falls, which gives a rounder, harder, more uniform granule than ordinary granulation. That matters on the spinner, where uniform dense granules throw further and land more evenly across a wide bout width, and in the shed, where a hard granule resists crushing and caking. Every grade here is a true compound: each granule carries the full declared ratio, so the analysis cannot separate in transit or off the spreader.

Compound Grades

In a compound fertiliser every granule carries the full declared ratio. That is the difference from a blend, where granules of different straight fertilisers are mixed and each granule carries only its own nutrient. A blend can segregate in transit, in the bin and on the spinner; a compound cannot. Against that, a blend can be made to any ratio at all, which is what makes matching a soil test exactly possible.

Roller-Granulated Compound Grades

Roller (extrusion) granulation presses the raw materials together mechanically rather than through a melt. It is lower-energy, it handles heat-sensitive ingredients, and it produces a granule that breaks down readily in soil moisture. Like all compounds, each granule carries the full declared ratio.

Water-Soluble Grades

These dissolve completely and go on through the irrigation system or as a foliar spray rather than being spread and waiting for rain. That buys timing and precision, at a higher cost per unit of nutrient, which is why most irrigated operations run a granular base at planting and soluble grades through the season. Have the irrigation water analysed first: hard water, high bicarbonates or high pH cause precipitation in the line no matter how good the fertiliser is.

Blended Grades

A blend mixes straight fertilisers — urea, DAP, MOP, ammonium sulphate and others — to a chosen ratio. Because the ratio is set by what goes into the mixer, a blend can be made to any analysis at all. The grades below are the ones held as standing blends; where none of them fits your soil test, we blend to your number instead of selling you the closest thing on the shelf.

Straight Fertilisers

A straight supplies one nutrient at the highest analysis available, so you pay freight on the element you are short of and nothing else. They are also the building blocks every blend is made from.

Which Line Should You Be Reading?

Start with a current soil test. It tells you which nutrient is actually limiting yield, and that decides the family before it decides the grade — phosphorus-led at sowing, nitrogen-led through vegetative growth, potassium-led into fruit fill.

Send us the test and we will match a grade and a rate to it, or tell you plainly that none of these is right and what is. Minimum order 10–25 MT, delivered Australia-wide and shipped worldwide. We do not sell online — every order is a written quotation covering product and freight. Request a quote.
