Farmers turn to soil science technology as soaring fertiliser prices take hit out of bumper crop | Farming

Tim McClelland is one of a number of Australian farmers currently being compelled to rethink the way he operates this calendar year, positioning bigger reliance on soil science engineering in the wake of soaring fertiliser rates.

McClelland, a mixed farmer primarily based in north-western Victoria, is at present shelling out $1,100 a tonne for fertiliser, up from $650 in 2021, as the climbing price tag of power sales opportunities to history charges.

Although McClelland has usually depended on the results of soil sampling to apply variable costs of fertiliser across his farm, the value squeeze tends to make it a lot more crucial than at any time to use the nutrient judiciously. In prior decades he examined half the soil zones in his farm, but this calendar year he has tested just about all of them.

“[Soil sampling] tells us how a great deal nitrogen phosphorous we had in our soil at the start out of the 12 months, which then makes it a lot easier for us to match our offer to our demand from customers,” he mentioned.

Fertiliser is one of a number of imports producing farmers fiscal suffering, inspite of projections of a bumper year.

Andrew Whitelaw, an agricultural current market analyst at Thomas Elder Marketplaces, stated the most up-to-date fertiliser selling prices of $960 a tonne are extra than double the common value of $405 in between 2017 and 2020.

Whitelaw stated farmers can use much less fertiliser if they make use of technologies which help them be far more prescriptive in its application.

Even though a great deal of farmers currently used soil sampling, the fertiliser price ranges are generating the exercise a lot more refined in a craze that will probably go on, even as soon as fertiliser selling prices fall all over again, stated Whitelaw.

In accordance to Cheryl Kalisch Gordon, commodities analyst at Rabobank, Australian farmers use 6-7m tonnes of fertiliser each and every yr, with the utilization of some fertilisers forecast to maximize due to the nation’s growing agricultural production.

Kalisch Gordon mentioned Australia’s provide was notably uncovered to the international current market, with a major reliance on foreign importation.

Australia imports 100% of its potassium – one of the nutrition in fertiliser – from the US, Canada and Belarus, but imports from Belarus are at present unattainable due to the war in Ukraine.

Australia also imports 93% of its urea, which primarily comes from Qatar, Saudi Arabia and China. Kalisch Gord
on explained this provide is also strained owing to China’s export bans to safe its domestic materials.

Much more regarded application of fertiliser use will come as specialists emphasize the need to have to tackle the world wide mismanagement of phosphorous – a further essential component in fertiliser – in the most in depth report still on the phosphorus challenge.

Bryan Spears, professor at the Uk Centre for Ecology and Hydrology and a direct author of the report, claimed “phosphorus could thrust us to the brink of a foodstuff protection disaster. It is a finite source, and it is overused in designed nations, though establishing nations do not have more than enough.”

McClelland said nitrogen bank quantities are made to aid farmers accomplish 80% generation potential, which is the highest produce achievable, presented the other 20% will be affected by elements over and above farmers’ management such as frost, bugs and weeds.

McClelland mentioned the testing experienced not automatically saved fertiliser, but “certainly helped” redistribute the fertilisers from spots that did not will need it to spots which did.

He mentioned his farm was employing considerably less fertiliser than last 12 months for the reason that he experienced intentionally planted far more paddocks of pulses this kind of as lentils, which need much less fertiliser.

Justin Everitt, the chair of the New South Wales Farmers Grains Committee, explained he predicted the practice of grid sampling, additional in-depth soil assessments and variable mapping to be “wildly up”.

Everitt reported farmers also need to have fertiliser to acquire advantage of the fantastic seasonal conditions.

“The difficulty is, we’re having these a good calendar year, as significantly as rainfall goes.

“The opportunity for a superior crop indicating that we’re just going to have to suck these rates up and carry on on as regular,” Everitt mentioned.

Prof Michael McLaughlin, director of the Fertiliser Technology Research Centre at the University of Adelaide, reported high charges normally drive farmers to boost their effectiveness, but there was a danger when charges are so large that farmers start out to look for alternate options, which are less costly but not as helpful.

Standard different solutions these kinds of as animal waste and compost are feasible for residence gardens, McLaughlin mentioned, but logistically not probable when 30,000 hectares required to be sewn inside of a couple of weeks.

Everitt stated fertiliser charges experienced taken a “massive hit” out of final year’s bumper crop, the financial savings from which would generally have been set absent for poorer seasons in the long term.

“We imagined we’ve had a very fantastic run previous year … and lo and behold all these higher fertiliser charges, substantial gasoline prices and then substantial chemical [prices have] just eaten absent at the surplus that you probably program to place absent for a drought.”
