Watch: how to use plant tissue tests for better results
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 […]
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 […]
