Which nutrient can help plants combat stress such as drought and disease?

Potassium is known as an essential nutrient that plays a crucial role in helping plants manage stress conditions such as drought and disease. It is involved in several physiological processes, including the regulation of stomatal opening, which affects transpiration and water use efficiency. By improving a plant's ability to retain water during dry conditions, potassium helps mitigate the effects of drought stress. Additionally, this nutrient is key in strengthening plant cell walls, which can enhance resistance to diseases and pests.

Furthermore, potassium helps in the activation of enzymes necessary for metabolic processes that boost the overall vigor of the plant. With improved overall health and stress response, potassium enables plants to better cope with challenging environments, making it a vital nutrient for maintaining resilience against various stresses.
