    Soil and Nutrition, 27 Jan 2025
    Decision-support tools can avoid costly under-fertilising

    Concerns about environmental impacts, cost and crop performance may be leading southern grain growers to under-fertilise, missing out on potential yield gains of up to 40 per cent. Dr Yolanda Plowman, a senior research manager at Birchip Cropping Group, encourages the use of support tools, such as Yield Prophet®, and nitrogen banking to optimise nitrogen use.
