Boron is one of the most important trace elements in plant life. It helps to normalize the synthesis of nitrogenous substances, and also improves metabolic processes and increases the content of chlorophyll in the leaves.
Boric acid (H₃BO₃) is the simplest and most readily available boron compound. It is widely used in various complex fertilizers. It is a colorless crystalline substance in the form of odorless flakes. Boric acid is easily soluble in water, and the acidic properties are very weak. If the amount of available boron in the soil corresponds to the norm, then the yield and keeping quality of fruits increase, in addition, the overall resistance of plants to adverse conditions increases. How to use fertilizer in the garden and vegetable garden?
Stimulation of seed germination.
Boric acid solution: 0.2 g of boric acid per 1 liter of water. Seeds of carrots, tomatoes, as well as onions or beets must be soaked for 1 day; cabbage, cucumbers, zucchini – for 12 hours. When sowing a large number of seeds, it is better to dust them with a powdery mixture of boric acid and talc, advises supersadovnik.
Soil preparation for sowing and planting.
Boric acid solution: 0.2 g of boric acid per 1 liter of water. Before sowing or planting seedlings, the planting ridges should be shed with a solution (consumption – 10 liters per 10 square meters), dusted and only then the seeds should be sown. This method is used as a prophylaxis for suspected boron deficiency in soils.
Boric acid solution: 0.1 g of boric acid per 1 liter of water. The first spraying is best done in the budding phase, and the second – in the flowering phase, the third – during the fruiting period of the plants. When combined with other trace elements, the concentration of boric acid must be reduced to 0.05–0.06% (5–6 g of the drug is diluted in 10 liters of water).
Top dressing at the root.
Boric acid solution: 0.1–0.2 g of boric acid per 1 liter of water. It is used exclusively in cases of severe starvation or a well-known lack of boron in the soil. Plants must first be watered with plain water to avoid chemical burns of the roots. As a rule, it is used on seedlings of flowering plants that grow on soddy-podzolic soils or in a mixture of peat and sand.
Boric acid dissolves easily only in hot water. Always first you need to dilute the sample (bag) in 1 liter of hot water, then bring to the desired volume with water at room temperature. Foliar top dressing (spraying) should be carried out in cloudy weather, and preferably in the evening, to avoid sunburn. On hot, dry days, water the plants thoroughly in advance.
Experienced gardeners advise do not spray with boric acid solution beets, and spray. It is necessary to dilute five grams of boric acid in 10 liters of water. In this way, one foliar top dressing is carried out when the beets have four to five leaves. Boric acid improves the taste of the root crop.
