A new demonstration trial in North Motton, Tasmania focused on optimising fertiliser practices in potatoes by evaluating varying rates, timings (pre-spread, at planting, and top-dress), and approaches (crop sampling and conventional programs) to improve grower profitability and potato marketability.

Magnesium (Mg) is essential to plants. It is strongly involved in photosynthesis and transporting carbohydrates from leaves to roots, which is particularly important for tuber development. Yet, it may be overlooked within fertiliser programs focused on N, P and K. Read about the Mg mini trial in this PotatoLink magazine article.
