What is the best way to apply trace elements?

For a short-term fix, a foliar spray is the easiest, cheapest, and a reliable way to apply trace elements to crops. There are also options to help build soil reserves for future crops.  Zinc (Zn) For a minor deficiency and/or in a known Zn-deficient paddock, Zn seed dressings can supply […]

Watch: how to use plant tissue tests for better results

Chris Dowling photo for tissue tests article

Chris Dowling explains the keys to successful sampling and interpretation of plant tissue tests in winter crops. Why use tissue tests? Plant tissue tests ask the crop ‘what’s wrong?’. Ideally, analysis can get to the core of an issue before yield has been overly compromised. Plant tissue results are more […]

How to choose the best way to manage zinc deficiency

Zinc seed dressings can effectively supply zinc to a young crop. The amount of nutrient that can be applied in a seed dressing depends on the size of the seed. Small seeds can carry less of the coating media than large seeds. Seed dressings do not apply sufficient zinc to […]

Zinc deficiency shows up in the cold

The cold snaps seen in southern Australia this year gave conditions where zinc deficiencies typically appear. Zinc deficiency tends to occur early in the growing season when soils are cold and wet. Shoot growth then outpaces root development. Root-pruning herbicides can induce zinc deficiency by the same mechanism. Zinc deficiency […]

Nitrogen low in the West

Plant-available nitrogen in the soil profile is lower across the western grainbelt this year compared with the previous four years. Grain growers across the Western region are urged to monitor crops for nitrogen deficiency. Last season’s high grain yields and the dry summer have combined to reduce soil nitrogen. For […]
