Remembering Robert Stephen Drewitt

It is with profound sadness that we announce the passing of Robert Stephen Drewitt, aged 58, who passed away on Friday night 23rd October 2026, after his fight with cancer.

For 30 years Robert was far more than an agronomist to us; he was a trusted advisor, a cornerstone of our company, and a cherished friend, like a close family member. His passion for the land, deep knowledge of Agronomy, and commitment to our clients set a standard of excellence that defined our business.

To our clients who had the privilege of working alongside Robert, we know you share in our grief. His knowledge, kindness, and steady guidance will be irreplaceable.

Robert’s parting words to me, a few nights before he passed were, “John remember me as you knew me, not the way I am. I am at peace, and my memories of all the stuff we did together over the years I will take with me. Thanks for the good times.” and likewise Robert, we will always remember you. You will never be forgotten.

Robert is survived by his wife and 3 children.

As we honour Robert’s memory, our team remains fully committed to supporting your operations and carrying forward the high standards Robert established. Should you have any ongoing projects or urgent needs, please reach out to us at Kismet International / Agronomy Services Australasia / Guano Australia.

We thank you for your understanding, kindness, and sympathy during this time.

Robert Stephen Drewitt

3^rd April,1968 - 23^rd October,2026.

WHAT OUR CUSTOMERS SAY

Being so far away from our markets, durability is critical and the Silica is really good in terms of hardening up the skin and making the melons better to transport.Ord River WA irrigator David Menzel-Barradale

The problem with many organic fertilisers is that they have very low rates of nutrients, meaning you need to put out high rates. A product like Guano Gold has 12pc P, whereas Guano Sulphur Gold has 10.5pc P, obviously with additional sulphur. These figures compare very favourably with something like a single superphosphate product. Agronomically, it’s a good product in any setting, not just for organic producers.Garry Allison, Landmark Agronomist. Mount Gambier, SA

For the broadacre croppers, Guano Gold works really well in paddocks where they have had issues with nutrient tie-up. He said the majority of synthetic P products have large rates of water soluble P. The problem with that is that you can have instances where it ends up tying up zinc in the soil so you run into problems with zinc deficiencies. Not only does the slow release nature of the Guano Gold product work well over the entire season, it also contains zinc for the crop as well as the other nutrients.Moree agronomist Rob Drewitt

We strongly recommend the Guano Gold products to fellow farmers if they are looking at improving their Calcium and Silica levels using various methods of application such as foliar and granular.James and Aimee Thomas Falkirk Macadamia Farm

I have recommended Guano Gold products for 20 years and in all cases had excellent long-term results increasing in pasture productivity.Paul Baguely - PB Ag Consulting

They are high analysis products so you get your nutrients without having to put too much fertiliser out.Anthony Beutel, Googa Farm Organics

We have known since the 1930s that phosphorus is one of the main elements required to grow a successful crop of not just the (flax) plant but the seed. It was one of those products that was first out in a granular type form and it was so much easier to get an even coverage over the ground, rather than a powder form. Later on the product became a little more refined, so we could put it through our air-seeder. We also broadcast some of it, prior to seeding, when we are cultivating ground. The products have great characteristics in relation to phosphate and silica, which is exactly what we need for flax.Waltanna Farms flax-seed farmer & Ambassador for Guano Australia, Michael Nagorcka
