Proper fertilization for foliar feeding


Everyone has their favorite occupation, and a considerable number of people take great care in caring for plants. How wonderful it is to observe the spitting of a seedling from a seed, to look after the period of active growth and, doubly nicely, to reap the rewards of a grateful green pet. But, for a good harvest, you need to make feeding and fertilizer, including foliar.

Rules for caring for plants always include:

  • loosening the soil;
  • watering;
  • fertilization;
  • weeding;
  • pest protection and treatment;
  • pruning or pinching;
  • preparing plants for winter

You can fertilize in several ways:

  1. The main method involves fertilizing into the soil before planting plants.
  2. Seeding method is done at the time of planting seeds.
  3. Top dressing is the introduction of nutrients in the period of life. Top dressing is root, foliar (leaf), interrow and method of fertigation.
Foliar application consists in spraying fertilizer on leaves and plant stems.

What is foliar top dressing

Foliar top dressing is an additional way to add nutrients dissolved in water by spraying on the ground part, bypassing the roots.

Studies show that the batteries applied to the leaves and stems of plants actively penetrate the green body and are absorbed much faster.

The ideal way to quickly make food in small doses, with a visual reaction of the plant.

When is she needed

The main incentives for deciding on foliar feeding:

  • modernization of fertilization methods;
  • due to low temperatures, salinity, underdevelopment of the root system, plant do not receive batteries from the soil, which leads to a deficiency of nutrients, and leaf supplements will provide essential trace elements in the shortest possible time and in full;
  • powerful root stimulationbecause the leaf nourishes the root, increasing the capacity of the reinforced root to absorb food from the soil;
  • increasing the intensity of photosynthesis;
  • applying fertilizer, following the stages of plant development, for example, at the time of the extinction of the activity of the root system;
  • bush height does not allow interrow introduction fertilizers;
  • the combination of foliar application with pesticide treatment, before this, having carefully studied the compatibility tables, so as not to cause new compounds;
  • saving of batteries due to local introduction
Foliar top dressing is used when root introduction is impossible.

For the complete assimilation of food by the sheet, it is generally accepted to highlight strict rules:

  1. Fertilize at the time of the best development of the vegetative apparatus of the bush.
  2. The solution should fall on the top and bottom of the leaf and on the stems;
  3. It is necessary to spray the solution in the dark or on a cloudy dayas the sun dries the solution before the plant absorbs it;
  4. Ambient temperature no higher than 20 degrees.
  5. Must be windless not rainy weather.

What fertilizers are most suitable

It is important to know, in the implementation of leaf nutrition, the principles of absorption of certain elements.

Nitrogen fertilizers

Lack of nitrogen during the growing season dramatically reduces yields, as well as the quality and protein content. Nitrogen fertilizer is better to spray on the sheet in early spring in order to improve the activity of photosynthesis, growth rate, tillering and the development of reproductive organs.

Late leaf feeding does not affect the yield, but significantly increases the quality protein content in fruits.

The best results were shown by feeding the leaves with carbamide, which contains the amide form of nitrogen.

Potash phosphate

Potash and phosphorus-potash fertilizers, contribute to accelerated fruit ripening, at the same time increase of the qualitative characteristic of a harvest is noted.

It is important to remember that potassium insufficiently and slowly absorbed through foliage, potassium ions are very large and difficult for them to pass through the leaf cuticle. It is advisable to make potassium in dry weather, to maintain the elasticity of the sheet.

Magnesium and trace elements

  • Magnesium has excellent sheet absorbing propertiesIt is introduced simultaneously with urea in the form of magnesium sulphate.
  • Biostimulants based on algae.
  • Trace elements are introduced in the form of chelates - complex organic compounds characterized by a developed organometallic complex, in which the chiliating agent effectively keeps the metal ion in a soluble state until it enters the plants. The introduction of trace elements in the form of organic salts is considered ineffective due to the fact that fertilizers are not absorbed, toxicity, the formation of new compounds in the soil and the plant, burns at the point of contact.
Algae based biostimulator

How to cook foliar feeding in the country

To increase the yield of apples, it is necessary to carry out sheet meals three times. carbamide (synthetic urea). In the spring, while the leaves are still tender, apply 0,3% (three grams of urea per liter of water) solution, and in summer and autumn 0,5% (5 grams of urea per liter of water).

If there was a long and cold spring, before the plant blooms, it is urgent to feed it with the following composition:

Ammonium nitrate (amount of nitrogen 46%) - 20.0 g. dissolved in two liters of water, added potassium chloride - 20.0 gr. and copper sulfate - 1.0 gr.,

dissolved in 3 liters is added to this mixture superphosphate - 200 gr. The mixture is filtered if a precipitate is formed and the plants are treated with the solution obtained.

In the case of a dry and hot summer, it is necessary to treat the leaves with a solution of potassium chloride 100 gr. 10 liters of water, it will increase the turgor of the leaves.

First feeding

The first foliar application is made before the formation of flowers

Before the plant blooms, it is urgently necessary to feed it with the following composition:

  1. Double granular superphosphate (increased phosphorus content, and good solubility) - 200.0 g., dissolved in 3 liters of water during the day in a plastic container;
  2. Ammonium nitrate (amount of nitrogen 46%) - 20.0 g. dissolved in two liters of water, added potassium chloride - 20.0 gr. and copper sulfate - 10.0 gr., boric acid 1 gr., potassium sulphurous - 80 gr.
  3. Acidity is neutralized with a solution the lime.
  4. Both mixtures are mixed and 5 liters of water is poured.

The introduction of such a solution in the spring guarantees yield increase by 20%. At the time of flowering plants do not feed.

The second

After plants bloomed, should hold a second bait:

  • Double granular superphosphate (increased phosphorus content, and good solubility) - 200.0 g., dissolved in 3 liters of water during the day in a plastic container;
  • Ammonium Sulphate - 50.0 gr. dissolved in two liters of water, added potassium sulphurous - 100 gr. Both mixtures are mixed, the acidity is neutralized with a solution soda, and pours 5 liters of water.


The third foliar application is made before harvesting.

Before harvesting recommends a third dressing:

Double granular superphosphate (increased phosphorus content, and good solubility) - 400.0 g., dissolved in 3 liters of water during the day in a plastic container. 4 glasses wood ash insist day in three liters of water, mixed with dissolved superphosphate, neutralize the acidity with a solution of food soda, add 5 liters of water.

Such a fertilizer improves the taste of the fruit, improves their duration of preservation during long storage and transportation.

When applying foliar application, it must be remembered that in no way this method replaces the standard methods of fertilizer application, but serves as an additional source that increases productivity, plant vital functions, taste and fruit preservation.

Never exceed the permissible concentration of the solution, the risk of plant burns increases significantly, carefully read the instructions for fertilizers.

Carefully distribute the fertilizer applied on the surface of the ground part, if you skip the lower elements, the quality of the spray will fall.

Be attentive to the stages of development, the erroneous application of fertilizer leads to the non-receipt of the necessary fertilizers, and an overabundance to a lack of harvest and the development of tops.
