Potassium (K) is a fascinating macronutrient. In corn, it sets the stage for a healthy and vigorous plant that produces a beautiful ear. Even though K is mobile in plants and helps deliver water and ...

Potassium is the most important yield-limiting nutrient in soybeans, and the plants can suffer a deficiency of it at multiple stages of growth. A new video produced by the University of Arkansas ...

When it comes to stressed corn plants, pictures can help explain what you’re seeing in the field better than the proverbially thousand words – especially this time of year, says Ken Ferrie, Farm ...

Potassium deficiency in soil has been revealed as a major threat to livestock and agricultural farming. So what does this mean for global food security and can the current threat be reversed? A study ...

Nitrogen and potassium are fundamental nutrients for plant growth, but imbalances frequently disrupt agricultural systems. In apple orchards, low potassium can severely limit carbon and nitrogen ...

Potassium deficient (-K) and potassium sufficient (+K) plants were exposed to four days of water stress. Well watered -K and +K plants had comparable rates of transpiration. But +K plants had a larger ...

Potassium deficiency in agricultural soils is a largely unrecognised but potentially significant threat to global food security if left unaddressed, finds new research involving researchers at UCL, ...

Feb. 20 (UPI) --Soils around the world are running low on potassium, a key nutrient needed for plants to grow. This ultimately means we may not be able to grow enough food for everyone. But it's not ...
