Saturday 5 December, is World Soil Day. The Food and Agriculture Organisation of the United Nations kicked off World Soil Day of recognition in 2002, and we’re using the occasion to celebrate the role healthy soils play in building productive and profitable farms.
By getting the trace elements in the soil right, farmers on Australian dairy farms often find they have the potential to drive increased milk production
Regular soil testing is necessary to make informed decisions on fertiliser use and soil management and the interpretation of soil test results is key to making the most cost-effective fertiliser choice. Dairying for Tomorrow’s Fert$mart program includes a range of tools to help advisers and farmers get soil “right” and make informed, cost-effective fertiliser management decisions.
Australian Dairy Farmer’s (ADF) Natural Resources Policy Advisory Group Chair, Daryl Hoey said insufficient fertiliser negatively impacts on pasture growth. This means less pasture and means farmers have to increase supplementary feeding or reduce stocking rates. Too much fertiliser, or fertilising at the wrong time means wasted resources.
“The key is to have the balance in soil just right so that nutrients are available for optimal pasture growth and are not lost in run-off into waterways and dams,” Mr Hoey said.
Soil health can also be improved by the implementation of a well-managed effluent system. Effluent is a valuable resource for reducing fertiliser costs, increasing soil fertility, adding organic matter to soil and providing valuable nutrients and moisture to crops and pastures.
“We now have a better understanding of effluent management than ever before,” Mr Hoey said. “The industry has moved away from a waste product mentality to taking a resource utilisation approach and, as a result, not only do we have improved productivity on farm, we are leaving our soils in better condition now and for future generations.”
Australia's dairy farmers have always had a strong commitment to environmental sustainability with industry bodies such as ADF and Dairy Australia coordinating a range of industry programs to help farmers manage fertiliser use, improve soil health and minimise the impact of effluent.
The dairy industry’s sustainability framework Mr Hoey explained, underpins the whole of value chain effort to minimise the environmental footprint of dairy.
“The framework has been used to identify priority areas, goals and objectives for sustainability,” said Mr Hoey. “It sets the scene for industry programs like Fer$mart and farmer investment and practices to deliver better results for both farmers and the environment.”
“Dairy farmers have a real commitment to managing land and water responsibly, reducing greenhouse gas emissions and protecting natural resources for future generations,” said Mr Hoey.
“And as a bonus, many farmers are finding that, with proper soil and fertiliser management, they can produce more feed at no extra cost.”
