Product Overview

Nutrifert’s granular soil amendment products have ultra-fine, hard granules that make them ideal for grower application and for blending.

The product range includes:

Oz Cal
Ultra fine granular lime

Ultra fine granular dolomite

Ultra fine granular gypsum

Soluble humate
available as a granule or powder

Silicon based products
available as granule or liquid

Grower application

These granular products can be applied using grower equipment, which means optimal timing and convenience. Application can be with worm or paddle drives, spreaders or droppers. Use in a blend or as a straight.

Prescription blends

Blending with NPK fertiliser allows a one shot application. As an example, NPK fertiliser and lime can now be taken care of in one application. We provide prescription blending at Townsville and Brisbane where NPK inputs from a third party fertiliser supplier are blended with Nutrifert products.

The granule size and hardness of our products  make them ideal for blending.

Variety of crop types

Nutrifert’s products are currently used in Australia across many crop types.  We recommend that growers talk to their agronomist or rural supplies store about using Nutrifert products for sugar, bananas, tree crops, horticulture, pasture, cotton, turf and other crops.
