In a recent GRDC Communities Crop Nutrition podcast, Dr Richard Bell from Murdoch University explained the importance of potassium (K) for optimal plant growth and reducing the effects of stressors such as drought, frost and salinity. K is second only to nitrogen in importance for crop growth. Many soils in […]
Hungry crops are more susceptible to frost damage. The best approach is to meet the crop’s nutrition needs. This gives the crop the best overall chance of dealing with stress, including frost. How do nutrients help? Crops develop stronger cell walls when they have enough copper (Cu) and manganese (Mn). […]
Having sufficient potassium reduces crop damage in frost events. Field trials in Western Australia showed benefits from potassium in wheat and canola. Richard Bell is a researcher at Murdoch University. In this video he explains: Crops respond more to potassium fertiliser in seasons that stress the plants with drought or […]
Crops may need extra Potassium when they under stress from drought or frost. There is a theoretical basis, and now GRDC funded research is looking into whether applying additional potassium is worthwhile when plants are under stress. Getting the right combination of drought and frost conditions to get meaningful results […]
