Avoid drought-induced potassium issues
Drought conditions can lock up potassium in the soil keeping it from reaching crops. Reid Abbott, sales agronomist for the Great Plains with AgroLiquid, tells Brownfield growers can take steps to protect their yields.
“Making sure we have that adequate potassium in the soil – you know, pre-season, leading up to that planting – is going to certainly be important but, certainly, in season. There’s plenty of potassium products out there available for growers to look at whether that be a foliar application or a maybe even a side-dress application of nitrogen.”
He says drought stress is very hard for plants to overcome when potassium gets locked up in clay layers of soil and roots can no longer take it up as quickly.
“It probably is going to start some tissue necrosis, things like that. Premature tissue death, cell death and all that’s going to lead to lead loss down the line, for sure.”
Abbott says potassium has many functions in soil and plants and a great number are related to water use efficiency.
