Types of dressings for potatoes

Foliar dressing has a significant impact on the quality of the future crop. You need to figure out when and what potato baits to use. About this and much more in the article.

The root crop can absorb substances not only if you put them in a dry hole or through the root system and soil, but through the leaves too... It makes sense to study what types of dressings exist and how they are applied for potatoes, strawberries and other crops.

Sheet

It is a fertilization of potatoes through bushes on the soil surface. Foliar feeding should be carried out in the evenings or in the morning... If fertilized in the sun, the solution will evaporate and damage the leaf tissue.

The plant assimilates nitrogen and magnesium well. Average absorption rate of sulfur. The process is carried out more slowly with the fertilization of calcium, phosphorus. Although foliar dressing is much faster than root dressing.

How to fertilize for a good harvest

Each useful element has its own function. If you increase potassium and nitrogen, then the mass of the tuber increases... If you add phosphorus, then you canincrease the number of root crops.

There is organic and chemical feeding. Each is good in its own way. Organic is not harmful and you can not be afraid to fertilize with excess. With chemical fertilizers, you should be more careful and apply according to the instructions indicated on the package in the preparation.

How to apply by spraying

Spraying fertilizer is a very convenient method of foliar feeding and helps to reduce the processing time of potatoes. This method is especially relevant for urea fertilization. To prepare the solution, you need to take 50 g of carbide and dilute it in 10 liters of water. Consumption - 3 liters per 100 sq.m.

Although it is much easier to use immediately ready-made fertilizer for spraying: Ideal, Surprise, Impulse Plus.

Foliar

Top dressing should be in different periods of growth plants. When flowering begins, half of the microelements have already been absorbed and foliar feeding will be ineffective. The best time is before bud formation begins.

Types of foliar feeding

Nutrients from top dressing are delivered through the leaves and stem... A solution is sprayed onto the surface of the bush. This type of feeding is needed for plant diseases.

With a cold snap and drought, the metabolism of the plant is significantly reduced, therefore, to maintain the strength of the root crop, it is necessary to spray fertilizer on the leaves.

Urea

Fertilization with Urea (urea) is considered one of the best nitrogen baits... It is produced in the form of white-gray granules, less often in tablets.

Urea has a beneficial effect on productivity, increases the number and weight of root crops. Foliar dressing is carried out by irrigation with a solution in a proportion of 3 liters per 100 sq. M.

Method of preparation: Dissolve 50 g of urea in 10 liters of water. Irrigation is carried out with a 0.5-1% solution.

Phosphorus

From phosphate fertilizers, a water extract of superphosphate is suitable for foliar feeding. Phosphorus promotes the development of the root system... Fertilizers are poorly soluble and are well retained by the soil.

The most popular phosphate fertilizers:

• Superphosphate... To prepare a superphosphate solution, you need to take 300 g of the mixture and stir in 10 liters of water. To prepare a water extract, you need to take 3 tablespoons of superphosphate and pour half a liter of boiling water. Let it brew for a day. Then stir the mixture with 10 liters of water;
• Phosphate rock and bone flour... They are brought in during the autumn digging period and after germination. 300 g of flour should be mixed with 10 liters of water.

.

Humates

Humates - able to awaken the action of microorganisms responsible for the mineralization of organic matter. The benefits of humates are as follows: increases fruit growth, mass, increases the absorption capacity of the plant to accept trace elements.

Humate is available in the form of tablets, instant powders, in liquid form.

Method of preparation: Dissolve 10 g of humate in 10 liters of water. Let it brew for 15 hours. It is necessary to process the bushes in the sprouting phase during the budding period. Processing can be done a maximum of 2 times.

Nettle infusion

You need to make the tincture as follows: a 10 liter container is filled with two-thirds of nettle and poured with water, left to ferment for 14 days. The concentration is diluted with water 1:20.

Nettle can be mixed with other herbs: field horsetail, wormwood, you can add ash, mullein. Fertilizer is applied after germination.

Chemical

Best recipe chemical complex feeding: mix carambid at a dosage of 200g, boric acid 15g, potassium monophosphate 300g, potassium magnesium 40g, zinc sulfate 5g, manganese sulfate 5g, colbate chloride 1g, potassium iodide 1g, copper sulfate 5g, iron sulfate 1g, water 10l.

Organic

Organics are good because does not have a toxic effect on the plant and you can cook it yourself.

There are the following options for organic foliar fertilization:

1. Pour 0.5 kg of weeds with 5 liters of water and let it brew for 10 hours. Filter the solution, pour it into the potato irrigation apparatus and feed the plant;
2. pour a layer of peat and straw with 5 liters of water and let it brew;
3. process with nettle infusion.

Dosage

The main element that allows you to improve the quality of the crop - nitrogen... Correct introduction of this element helps the fruit to grow, improves keeping quality. Just as important magnesium, boron and zinc... In the spring, you need to add nitrogen and a small amount of phosphorus and potassium. Closer to autumn, on the contrary, there is a minimum of nitrogen, and there is more phosphorus and potassium.

Any preparation contains a large percentage of a certain trace element. You need to understand when calculating which element is needed for your potato crop.

It is effective to use the drug Nitrofoski or make a solution: 30 g of superphosphate, 30 g of urea, 60 g of potassium chloride. It is recommended to treat shrubs with urea: after flowering, then a month later and last time 3 weeks before harvest.

Before applying top dressing you should carefully read the instructions.

What foliar fertilizers to feed potatoes

So that potatoes grow well, bushes need microelements... The main ones are:

1. Nitrogen... With a deficiency of the element, the leaves begin to brighten and acquire a light green tint, and young shoots stop growing. The ovary may fall off. Urea is used for feeding;
2. Phosphorus... With a shortage, potato leaves stop growing and begin to die off. The trace element is responsible for the development of the root system, increases the plant's resistance to diseases;
3. Potassium... Improves potato resistance to drought, disease, strengthens the root system and stem.
4. Manganese... Stimulates plant growth, ensures the movement of sugars in the plant.
5. Boron... Improves plant resistance to drought and disease.
6. Magnesium... The plant begins to grow faster.
7. Iron... With a shortage, the leaves begin to turn yellow.
8. Copper... The leaves begin to curl and dry out with a lack of a trace element.

The most important thing is not to overdo it with fertilizers, otherwise the opposite effect will work. I wish you a rich harvest!
