Fertilizers with potassium (K):

Potassium (K) is an essential macronutrient for plant health and productivity, playing multiple key roles in their development and metabolism. Unlike other nutrients, potassium is not a component of cell structures, but it is crucial for various physiological processes.

One of the most important functions of potassium (K) is regulating the water balance of plants. It facilitates the opening and closing of stomata, tiny pores in the leaves that allow gas exchange and transpiration. This helps plants manage water efficiently, reduce drought stress, and maintain cell turgidity, which is vital for overall plant growth and resilience.

Potassium (K) also plays an essential role in protein and carbohydrate synthesis, as well as in the activation of enzymes involved in photosynthesis and starch formation. These functions contribute to vigorous growth and greater biomass accumulation and fruit quality.

Additionally, potassium (K) enhances plant resistance to diseases and pests by strengthening their natural defense systems and increasing their ability to adapt to adverse conditions. It also supports resistance to abiotic stress, such as heat and drought.

Potassium (K) deficiency can cause symptoms such as brown leaf edges, reduced fruit size, and decreased resistance to diseases and stress conditions.

Maintaining adequate potassium (K) levels in the soil is crucial for ensuring optimal plant development, high production, and good crop quality. Applying potassium-rich fertilizers helps correct deficiencies and promote healthy, productive growth.
