Phosphorus is an integral part of metabolic energy (ATP), cell walls and the genetic information (DNA) of the plant. It plays an essential role in cellular multiplication and photosynthesis, hence its importance in the early stages of the plant’s development. Potassium promotes photosynthesis. It contributes to the transport and build-up of sugars. It also takes part in filling out grains, favours better water usage and nitrogen optimization, and increases resistance to frost, drought, and disease. Zinc is crucial for the synthesis of auxins and stimulates plant growth. It also favours the synthesis of acids and proteins. Boron is essential to stabilize cellular membranes (greater nutrient absorption), pollen fertility, fruit set, synthesis of hormones, production and transport of sugars, and calcium assimilation. IBA encourages growth and is especially effective for the formation of roots.
