Cal-Gran and Cal-Gran blends provide a less volatile source of nitrogen for surface application of nitrogen fertilisers.
The nitrogen in Cal-Gran is present in two forms, nitrate nitrogen (7.4%) and ammonium nitrogen (16.5%). The ammonium nitrogen content makes it less susceptible to volatilisation losses than surface spread urea.
Cal-Gran also contains sulphur (10.8%) and calcium (4.4%).
Cal-Gran fertilisers were developed for a range of uses including ratoon cane in Queensland and northern New South Wales, along with horticultural crops and dairy pastures.
Key benefits of Cal-Gran
- Improved nitrogen efficiency, increasing the potential for better yields
- A fast growth response due to immediately available nitrate nitrogen, even in cooler conditions
- Allows for a more timely and convenient granular fertiliser application compared to other methods
- Contains sulphur and calcium, essential nutrients for sugar cane and pastures. The form of calcium in Cal-Gran helps reduce soil acidification due to its neutralising value.
Cal-Gran fertilisers are not classified as security sensitive ammonium nitrate (SSAN).
Cal-Gran fertilisers are available in blends with phosphorus (as DAP) and potassium (as muriate of potash) where required.
