Phosphorus and potassium in plants：
Although nitrogen supports vegetative growth in plants, phosphorus and potassium are important for strong rooting, flowering, and fruit development. They are especially important in fruit, vegetable or flower gardens. But before adding these nutrients to plants, you need to ensure that the nutrients needed by the plants in the fertilizer are balanced.
Benefits of phosphorus
Phosphorus is a nutrient that helps root development, flowering, and fruit production. This is especially important for flowers, fruit trees and vegetables. It is also the most important ingredient in booster formulations, it can encourage flowering plants to bloom.
The role of potassium
The most balanced fertilizer contains a lot of potassium, which is responsible for the overall metabolism of the plant. It also has many auxiliary functions, such as promoting root growth and improving the quality and size of certain plant nuts and fruits. Because other nutrients must succeed, it is a key ingredient in most fertilizers (especially balanced mixtures).
Excessive planting of gardens containing phosphorus and potassium can be as harmful as without fertilization. For example, in vegetable gardens, applying phosphorus when not needed can reduce the ability of vegetables to absorb micronutrients such as iron. At the same time, too much potassium will cause salt accumulation in the soil, thereby burning the root system.
