We are talking about the benefits of spring fertilizers, their views and what drugs choose depending on the variety of the plant.
Every gardener wants to get a good harvest. But the result depends not only on the variety, landing and care terms, and from the preparation of the soil to landings. Over time, it consumes the supply of nutrients and, if not to replenish it, the plants are poorly developing and fruit. We'll figure it out how to feed the mineral fertilizer in the spring.

Agronomas annually carry out simple calculations to determine the required amount of nutrients for planting crops. At the same time, predecessor plants are taken into account, since the consumption of trace elements is different. Ideally, gardeners can do the same, that is, to perform an analysis of soils to determine the content of different substances in it. After that, to calculate the desired dose of drugs.The best time to bookmark fertilizers, experts consider spring months. This is explained by two factors.
Why spring is the best time?
- It is possible to calculate the dose of elements as accurately as possible for each culture.
- The number of drugs can be reduced. All mixes that come in spring are immediately used by plants. Therefore, they should be much smaller. Autumn feeding is also possible, but for the winter most of the most useful substances are washed out of the ground or destroyed. On average, no more than 20% remain.
The agronomists allocate three periods in which it is recommended to fertilize the ground with detvering drugs. Describe each.
Three periods in which land can be fertilized
- In the snow. The mixture is scattered over the snow cover started to melt. The main advantage - work is carried out quickly and easily. But there are disadvantages. It is impossible to calculate the desired dose, since the part of the empty waters. It is not recommended to deal with the organic matter, it is allowed to scatter in the snow only mineral mixtures.
- Prepaiming preparation. The introduction of drugs is carried out at the Packet of Earth. So they have time to fit into the depths of the soil layer. Advantage of the technique - accurate dosage.
- When landing. The mixture is covered in the planting fossa or groove. The main disadvantage of the methodology is the high probability of non-compliance with the dosage. Calculate and measure the desired number of granules or powder is not always possible.
When determining the number of drugs, it must be remembered that it is necessary to feed cultures during the entire growing period. The total dose made by the same time will give more harm than good. It is best to break it at least three applications.
Types of drugs
Before determining which mineral fertilizers are made in the spring, find out what they happen.There are comprehensive and simple formulations. The first contains several active ingredients, the last only one.
Simple divide into four groups.
Nitrogen
The main component - nitrogen. It increases the green mass, increases the yield of cultures. With a lack of an element in plants, unpleasant symptoms appear. They are especially brightly noticeable at Polenic, including potatoes and tomatoes, on an apple tree and strawberries. This is the appearance of weak thin escapes, slow growth, a decrease in the number of inflorescences. The leaves in the fruit become red, in vegetables - yellow, become small, shivered. All this indicates that it is necessary to introduce nitrogen compositions. This is a "sulfate ammonium", "ammonia Selith", "Calcium Selith" and others.
Before you contribute, it is important to correctly calculate the required amount. Nitrogen overdose is dangerous because it accumulates in plants in the form of nitrates. Their excess can adversely affect health. Nitrogen is especially necessary for green cultures, grass on lawns, trees during the appearance of foliage.
Potash
Potassium is needed to absorb nitrogen. It increases the rate of the formation of proteins, reduces the number of nitrates, activates the development of the root system. Especially it is necessary for root crops and bully. For example, carrots, garlic, bows. For them, the norm increases. Signs of potassium deficit: Slim stem, slow growth, spots of brown or black color on a sheet plate. The edges of the sheet die out, the so-called edge burn is formed. Sheet plate is spinning with a tube.
The most common simple potassium compositions are: "Potassium chloride", "Calius sulfate", "Potash Selith".
Phosphorus
Phosphorus increases yield, increases the content of sugars in the fruits, accelerates their maturation. With the deficiency of the element, such signs are observed: poor germination of seeds, the edges of the leaf plate are wrapped, dry, leaves are covered with blue-green spots. Flowers and shoots are deformed. These symptoms are removed by the "double superphosphate", "superphosphate" and others.
Complex funds contain several elements, each of which has its impact. There may be two or three of them, they can be complemented by trace elements. Most often in the gardens use "Diammophos", "nitroammophos", "nitroposk" and others. Products are produced in a bulk and liquid form. In the first case, this is a powder or granules. It is necessarily given instructions for use, since an excess of feeding is extremely undesirable and can even be dangerous.
What mineral fertilizers need to be made in spring
Spring period is optimal for the introduction of a complex of nutrients. It is best to conduct presets, laying out products to a depth of 200 mm in the process of rescue.The average values of each substance at the rate of the area of 10 m2
- Nitrogen 300-350. This may be an "ammonium nitrate" or "urea".
- Potash 200 g. The potash Selitra is suitable or "Potassium chloride".
- Phosphoric 250 g. You can take "Superphosphate".
If a comprehensive agent is planned, the dose is calculated with the average indicators. Let us dwell on the preparations needed in the cultivation of individual crops.
For strawberries and strawberries
Strawberry in the spring needs fade by mineral fertilizers. It is held in stages. The first passes immediately after the snow came down, but already on warm soil. Under each bush poured a liter of the nitroammofoski solution. It is prepared, dissolving 1 tbsp. A spoon of funds in 10 liters of water. In the period of bootonization and pouring berries, potash and phosphorus mixtures give. Strictly in the right quantities. Already after collecting berries and later in the fall contribute.For garden trees and shrubs
Spring for shrubs and trees is very important nitrogen, which helps to gain green mass. Therefore, in the period of dissolving the kidneys, it is impaired in a rolling circle. For fruit trees - plums, cherries, apple trees, as well as for decorative, such as Tui or Tis - maybe dry introduction when the granules are added into the soil. Then the abundant watering is obligatory.
Shrubs are better to feed with liquid mortar. For gooseberries, raspberries or currants, 5 liters of liquid will be enough. m.
After a complete dissolution of the leaves, an extraordinary feeding is carried out. Prepare it from complex mixtures. Usually for bone (cherries, plums, alchi) prepare 0.5% solution, for seeds, such as pear or apple tree, we need 0.02% composition. For berry shrubs, there are also extricient feeding. It is performed in a month after the first. For the second feeding in the spring of mineral fertilizers, raspberries, blackberries, gooseberries and other shrubs are bred in a liter of water in 15 g of "Superphosphate" and "Potassium Sulfate". Good add more trace elements: Bor, manganese, etc.
For grapes
To obtain a rich harvest, the grapes in the spring requires feeding with mineral fertilizers. The first time the means is entered in the early spring period, immediately after removing the shelter. Per quarter. m goes 120 gr. Superphosphate, 50 g of "potassium sulphate" and "urea". Good add more compost and wood ash. A week before flowering, it is fed by a liquid solution of any comprehensive agent. Break it strictly according to the instructions. The third cycle is carried out 7-10 days after the berries started. An aqueous solution of "Humata potassium" is used for 1 liter on a grape bush.For vegetables
Before planting vegetables, you need to make macro and trace elements. As in the garden, they are washed out with water and plants feel their deficit. It is best to use complex compounds that contain an equal number of three necessary macroelements, for example, "Azophosk". It is desirable that trace elements attended them in addition to them. Granules or powder are optimally made by a dry method, under the poppop.
If vegetables are grown in a greenhouse, local contributions are considered the best technique. Gardeners prefer to fertilize the greenhouse organic. However, the spring mineral fertilizers in the greenhouse also apply. They are divided into sowing or seedlings. At the same time, the granules are mixed with the ground and sprinkled on top of the earth so that the roots do not touch chemicals. Sometimes in the wells or grooves add the organic.
For flowers
Flowers are sensitive to the organic and often poorly transferred it. Therefore, mineral mixtures are preferable for them. So, for perennials, such as delphinium, roses, tube and others, it is important to get nitrogen in time. Immediately after melting of snow and a stable increase in temperature in the soil, nitrogen preparations are made. During the bootonization period, single and perennials need potash-phosphorous mixtures.
Agronomas are not recommended to ignore the conduct of spring feeding in the country and garden. It should be understood that their term depends on the climatic zone. So, in the suburbs and in the Urals they will be held at different times. It all depends on the weather. But the set of macro- and trace elements is not different in general. Simple or integrated funds made in accordance with the instructions will give abundant flowering and a good harvest.
