Potassium (K) is essential for water uptake, photosynthesis, and enzyme activation in plants. It helps regulate osmotic pressure, enhances drought resistance, and improves overall plant vigor.

Iron deficiency in plants typically results in interveinal chlorosis, where the areas between the veins of leaves turn yellow while the veins remain green.

Molybdenum is crucial for nitrogen fixation in legume plants. It helps these plants convert atmospheric nitrogen into a form that can be used for growth, making legumes important for soil nitrogen enrichment.

Zinc deficiency can lead to stunted growth, distorted leaves, and reduced flowering. Visual indicators include interveinal chlorosis and small, misshapen leaves.

Boron is essential for cell division, as it aids in the formation of the cell wall. It promotes healthy root development, flowering, and fruit set in plants.
