Zinc sulfate: features of use

Increase the productivity can be if you use zinc sulfate. This is a universal fertilizer that is suitable for floral, berry, vegetable and fruit crops. Zinc is necessary for plants for growth and development. Irreplaceable it will be in the period of fruiting.

Why do we need zinc plants?

The need for useful microelements in different types of cultures is different. But they have similar deficiencies. If there is a lack of zinc, the plants will have small sheets. Fruits on them are formed rarely, they will be irregular in shape.

For a sufficient supply of zinc in plants in the soil, this trace element should be in a concentration of 0.5 to 0.25 mg / kg. In this case, it can penetrate into plant cultures from water-soluble forms. But on limy soils it practically does not dissolve. Because of this, the level of its entry into plants decreases. The availability of zinc also deteriorates when phosphate fertilizers are introduced into the soil.

Most clearly, the shortage of this trace element is visible on apples, grapes, pears. It is also noticeable in appearance of citrus, cereals and some types of vegetable crops. You can change the situation if you use zinc sulphate. The application of this fertilizer should be carried out according to established norms. This is the only way to improve the condition of crops and increase their yield.

Rules for the use of fertilizers

For the improvement of cereals, fruit, vegetable and flower crops, experienced farmers advise using zinc sulfate. A solution of this element is applied directly to the plants. If possible, try to spray both the top and bottom of the leaves. This will help improve the assimilation of microelements.

For spraying it is necessary to prepare a solution. To treat berry, fruit crops and flowers, it is enough to dissolve 3 g of zinc sulfate in 10 liters of water. Saturate cabbage and cucumbers can be, if you mix 5 g of fertilizer in the same amount of water. But for the treatment of tomatoes and various root crops you need 10 grams of zinc sulphate.

Spraying is carried out only in windless and dry weather. Treatment is best done in the evening or in the morning, avoiding scorching sunlight.

Zinc sernokisly can be added to the soil. This is done from the calculation that for 1 square. M of earth should receive 1 g of zinc sulfate.

External signs of micronutrient deficiency

Zinc sulphate is an excellent antiseptic. This is a crystalline colorless substance whose density is 3.74 g / cm ³ . Zinc sulphate is obtained by dissolving in sulfuric acid elements containing this metal. The obtained unwanted impurities are removed by means of a special purification.

With a shortage of zinc, fruit trees are affected by a rosette disease. At the ends of the branches, small chlorotic leaves are visible. They form a socket. The growth of roots becomes weak. If the lack of zinc is too large, then the problematic affected branches will die off.

There is a lack of zinc and corn. The new leaves will be light yellow or white. On the old yellow stripes are formed. The yield of such corn will be low.

Seed treatment

You can get the best yields if you prepare in advance for planting plants. For example, presowing treatment of maize seeds is carried out as follows: they are powdered with a special mixture consisting of 42 g of zinc sulphate and 150 g of talc. This amount is sufficient to process 1 centner of the seed.

Presowing treatment of seeds of other plants can be carried out differently. Many recommend that they be soaked in water, in which various trace elements are dissolved, including zinc sulphate. But put the seeds in solutions with fertilizers can be no more than a day.
