Why do you need to fertilize with boric acid?
Many gardeners use boron on their plots to treat certain plants, but not everyone knows what this substance is used for. Let's consider the main advantages of using boric acid:
- affects productivity;
- helps to increase the number of ovaries on plants;
- flowers stay better on the bushes during strong winds;
- the taste of the berries improves;
- plant leaves acquire a rich green color and do not dry out or die.
Fertilizing with boric acid increases yield and improves the taste of berries
Plant needs for boron, magnesium and calcium
Now let’s talk in detail about how plants behave if they are deficient in one or another microelement. When the balance of nutrients in the soil is disturbed, their absorption by plants is disrupted. They react:
- yellowing, brittleness of foliage;
- dropping ovaries and unripe fruits;
- low nutritional value;
- death of the tops;
- poor seed germination.
Complex application of microfertilizers helps cope with various diseases, helps plants resist frost, and increase yield.
Calcium requirements
Calcium deficiency affects primarily the development of the root system. Numerous hairs cease to form on the roots, through which more nutrients are absorbed. The root system becomes covered with mucus and rots, turning into a structureless mass. The plant dies.
Calcium helps balance the intake of other microelements, in particular aluminum and manganese, which become toxic in excess quantities.
In the presence of calcium, enzymatic activity in plants is activated, which also affects the absorption of nutrients and fruit development. Calcium is concentrated mainly in leaves and shoots. For comparison, it is 96% in corn leaves, and only 4% in grains . Therefore, it is important to use the green part in the compost so that the trace element goes back into the soil.
Cabbage and tomatoes consume the most calcium, which are very sensitive to soil acidity. Mag Boron fertilizer can replenish calcium deficiency and compensate for low soil pH with foliar fertilizing.
Consequences of magnesium deficiency
Magnesium plays an important role in the process of photosynthesis. is about 10% of it in chlorophyll molecules . With a lack of magnesium, the absorption of nitrogenous substances is impaired, which affects the general appearance of the plant - it is weak, with thin shoots, chlorotic yellowish leaves. Such a plant is not capable of producing a good harvest, since it does not have the strength to grow. At best, the fruits will be small and in small quantities.
The least amount of magnesium is found in sandy soils. Therefore, the only way to improve the situation is to apply fertilizer more often, but in smaller doses. Root feeding is not as effective as spraying the leaves with a solution.
Yellowing of the green plates between the veins is the first sign of magnesium deficiency. If you take action right away, the leaves will come to life in 2 - 3 days . If you delay feeding, the foliage will soon turn brown and begin to fall off.
Boron deficiency
Boron can independently form in the soil and also be eliminated from it independently. An important indicator is the presence of water-soluble forms of boron, which plants can feed on.
Boron affects the absorption of calcium by fruit-bearing plants. Together with magnesium and calcium, it is involved in photosynthesis and the formation of the root system. Accumulates mainly in leaves.
A sufficient amount of microelement affects the quality of pollen and attracts bees for pollination, which increases yield.
With a boron deficiency, fruits grow in non-standard shapes, this is especially noticeable in cucumbers, whose marketable appearance does not allow them to be sold at a good price.
The balanced combination of microelements in the Mag Bor fertilizer allows you to improve plant nutrition and influence the quality and quantity of fruits.
How to understand that strawberries need boron
Boron deficiency can be determined by the appearance of plants. Signs of a deficiency of this microelement are:
- dried edges of leaves;
- wilting even with abundant irrigation;
- deformation and falling of leaves.
With a lack of boron, strawberry leaf edges dry out.
Signs of excess boron
Excess boron, as well as its deficiency, disrupts the normal growth and development of strawberries. With a high microelement content, the growth of the roots and aerial parts of the crop is delayed. In addition, the accumulation of boron in the leaves leads to the formation of burns. Excessive feeding with such a substance can lead to necrosis. This is evidenced by the dried edges of the leaves, which subsequently bend and turn yellow.
