Which nutrient enhances disease resistance in crops?

Potassium plays a crucial role in enhancing disease resistance in crops. This nutrient is vital for various physiological processes, including water regulation, enzyme activation, and nutrient transport within the plant. Specifically, potassium strengthens cell walls, which can help inhibit pathogens from penetrating plant tissues. Additionally, adequate potassium levels contribute to the production of phytoalexins, which are natural compounds produced by plants in response to stress, including pathogen attack.

While other nutrients also have their respective functions in plant health, potassium is especially well-known for its role in increasing resilience against diseases and enabling plants to respond more effectively to stress conditions. This enhanced resistance not only helps to support overall plant health but also improves yields by reducing the impact of diseases.
