    Emerging new generation of nitrogen management tools

    Commercialisation has begun on the outputs from the Future Farm initiative, which sought to deliver more-targeted, precise and profitable fertiliser decisions in near-automated processes that are more efficient for agronomists and growers

  • Hope for novel soil amendments to lessen constraints
    Soil and Nutrition, 16 May 2024
    Hope for novel soil amendments to lessen constraints

    Trials of next-generation soil ameliorants start this year in New South Wales with the hope of lifting grain yields

  • Liming and spading trial shows value of strategic tillage
    Soil and Nutrition, 22 Apr 2024
    Liming and spading trial shows value of strategic tillage

    Given the slow rate at which surface-applied lime moves into untilled soil, strategic tillage has been considered the best way to correct subsurface acidity within a reasonable time frame. Now, the results of a four-year study indicate spading could improve soil pH and increase lentil yields across a range of liming rates and spading speeds.

  • Soil survey aims to help growers make informed decisions
    Soil and Nutrition, 27 Mar 2024
    Soil survey aims to help growers make informed decisions

    The federal Department of Agriculture, Fisheries and Forestry wants to target its investment to help farmers make well-informed soil management decisions. To this end, it is supporting regional soil coordinators to undertake a national survey to collect information on the soil issues and topics that farmers feel sufficiently well-informed about and those issues where greater support is needed.

  • Could manure be the magic ingredient to improve yields?
    Soil and Nutrition, 22 Mar 2024
    Could manure be the magic ingredient to improve yields?

    Long-term farming systems research shows that growing one crop a year with high levels of nutrients produces the highest returns.

  • Opportunities abound in a growing industry
    Soil and Nutrition, 18 Jan 2024
    Opportunities abound in a growing industry

    The latest estimates from the Australian Council of Deans of Agriculture, based on job ad numbers, are that more than six vacancies exist for every graduate of a university agriculture course. The Primary Industries Education Foundation Australia was created to promote and develop credible, objective teaching material for primary and secondary students.

  • Shedding new light on soil organic carbon in Australian grain systems
    Soil and Nutrition, 17 Jan 2024
    Shedding new light on soil organic carbon in Australian grain systems

    Detailed diagnoses of soil organic carbon in grain-producing systems are being explored using state-of-the-art facilities through a collaborative network. The University of Queensland team harnessed the Australian Nuclear Science and Technology Organisation Synchrotron facility in Victoria to examine (1) changes in carbon forms and their microscale distribution in bulk soils; and (2) their carbon fractions, as related to climate conditions, soil types, land use and management practices.

  • Where exactly does phosphorus fertiliser go?
    Soil and Nutrition, 18 Dec 2023
    Where exactly does phosphorus fertiliser go?

    New research aims to track phosphorus fertiliser in vertosol soils, helping to quantify just how much is used.

  • Fertile ground
    Soil and Nutrition, 13 Nov 2023
    Fertile ground

    Nitrogen use efficiency research has shown there is a high degree of inbuilt fertility in irrigated soils.

  • Heavy stubble loads demand grower flexibility
    Soil and Nutrition, 07 Nov 2023
    Heavy stubble loads demand grower flexibility

    In most cases, what growers do to manage retained standing stubble largely depends on their seeding system, but it also can be influenced by crop rotations, weeds, diseases, pests, stubble load, harvest machinery and how much ground cover is desirable. After three consecutive La Nina years contributed to three big winter crops, many growers have found heavy stubble loads increasingly challenging at sowing.
