Boric acid fertilizer serves several purposes in plant nutrition.

1. Promotes plant growth: Boric acid is an essential micronutrient for plants, and its presence in the soil helps in cell division, root development, and formation of new tissue, thereby promoting overall plant growth.

2. Enhances flowering and fruiting: Boric acid is known to improve flower initiation and pollination, resulting in increased fruit set and quality. It aids in the transport of sugars and carbohydrates within the plant, leading to improved fruit development.

3. Improves nutrient uptake: Boric acid acts as a facilitator in the uptake and utilization of other important nutrients such as nitrogen, phosphorus, and potassium. It enhances nutrient absorption and utilization efficiency by promoting enzyme activity in plants.

4. Prevents nutrient deficiencies: Boric acid acts as a preventative measure against boron deficiency in plants. Boron deficiency can cause various disorders, including stunted growth, reduced crop yield, and poor quality fruits and vegetables.

5. Increases disease resistance: Boric acid has antifungal properties that can help protect plants against various fungal diseases. It acts as a natural fungicide, preventing the spread of infection and promoting healthier plant growth.

Overall, the application of boric acid fertilizer can significantly contribute to the overall health, growth, and productivity of plants.
