Top dressing carrots in spring


Carrot is an undemanding plant, for successful growth it has enough watering and sunlight. But if the yield of this root leaves much to be desired, it is necessary to pay attention to the soil, perhaps it is depleted. To compensate for the lack of nutrients, you need to find the appropriate fertilizer. Fertilizers are applied directly to the soil or fed plants during the growing season.

Fertilizer beds before planting

Best of all carrots grow on neutral or slightly acidic soils, loose, filled with sufficient nutrients. Preparation of carrot beds begin in the fall, after the previous culture is removed. The best precursors for carrots are potatoes, peas and green cultures.

Important! Fertilizer for carrots when planting is desirable to make a wet soil.

The harvest of carrots growing on acidic soils will always be poor, the root system does not work well under these conditions, the plant is hungry. It is possible to determine the increased acidity by eye, focusing on weeds, or by purchasing special test strips. The following plants readily grow on acidic soil: horsetail, horse sorrel, buttercups. If there are many similar plants at the site, it means that liming should be carried out before planting carrots in order to reduce soil acidity. For these purposes, you can make lime and dolomite flour. Adding wood ash can also help.

Tip! Often, to improve the structure of the soil, peat fertilizers are applied to the beds. The best peat is lowland, it has an acidity close to neutral.

Unscrupulous manufacturers can sell under the guise of lowland peat horseback, with high acidity. A large amount of such peat can significantly increase the acidity of the soil.

Heavy, stony soil prevents the formation of high-quality root vegetables. During autumn preparation of beds, it is necessary to add humus or well decomposed peat to the soil, if necessary, you can add sand. The amount of humus depends on the density of the soil, if it is very dense, you need at least 2 buckets per square meter of beds, on lighter soils you can get by with a smaller amount. Sand contribute at least 1 bucket for very dense soil, for the rest half of the bucket per square meter of beds is enough.

Important! It is undesirable to use sea sand to improve the soil structure; it may contain salts harmful to plants.

If the autumn processing of the beds did not take place, these manipulations can be carried out during the spring digging.

Nutrients for carrots can be applied to the soil using mineral or organic fertilizers. When deciding which fertilizers to apply, it is necessary to focus on the last season, if then a lot of fertilizers have been applied, their amount this season should be reduced by half.

Organic matter on carrot beds must be applied very carefully, an excess of nitrogen fertilizers can completely destroy the crop. Nitrogen-fed root crops grow deformed, dry and bitter. If the fruits nevertheless grew even, having a marketable appearance, they will not be stored in winter.

Organic fertilizers are preferably applied to the soil a year before growing carrots, under the previous crop. Since organic compounds are not immediately available for absorption, the fertilizers left over from last year can serve to feed carrots. If the organic matter in the beds was not applied, you can fertilize the soil in the fall. Before the autumn digging of soil per square meter of beds, one-half of a bucket of well-rotted manure is brought in; it is necessary to scatter the manure in an even layer so that during the digging the fertilizers are evenly distributed.

Tip! To increase the sugar content in carrots, it is possible to add wood ash to the soil during autumn processing of the beds.

Carrots are very demanding on the content of potassium, magnesium and phosphorus in the soil; the normal development of carrots is impossible without these trace elements. These elements can be applied to the soil in autumn, spring, or during the growing season of carrots. In the autumn, it is advisable to use long-acting dry fertilizers, the amount of fertilizer for carrots is determined according to the instructions for the product. In the spring, fertilizers for carrots can be applied to the soil in dry or liquid form, it is advisable to use nutrients in liquid form during the growing season.

Important! The use of fertilizers that contain chlorine is unacceptable. Carrots are very sensitive to this chemical element.

Seed treatment

Carrot seeds sprout long enough to accelerate germination, you can use soaking in a solution of mineral fertilizers, adding growth stimulants.

Tip! Honey can be used as a growth stimulant, it contains many active substances that can increase the strength of seed germination.

For soaking it is necessary to choose products with a high content of potassium and magnesium, these trace elements help to accelerate germination, increase energy, the shoots are more robust. The solution is prepared according to the instructions, for soaking enough 2-3 hours. After soaking the seeds are dried, sown in the usual way.

Important! Seeds emerging during soaking are not suitable for sowing.

Fertilizers during the growing season

During the growing season it is necessary to feed carrots at least three times. If natural fertilizers are used, at least once a month.

If last year nitrogen fertilizers were not applied, this should be done before the carrot appears on the fourth true leaf. The choice is made in favor of complex chelated fertilizers, since they contain nitrogen in a form that is available for rapid absorption by the root system. You can combine the introduction of nitrogen and phosphate fertilizers.

When the tops of carrots reach a size of 15-20 cm, spend the second feeding. At this time, carrots are in need of potash and magnesium fertilizers. The introduction can be carried out as a watering at the root, and foliar way, spraying the foliage.

The third time feeding carrots carried out a month after the second. This time also use fertilizers that contain magnesium and potassium.

Signs of nutritional deficiencies

If a carrot is nutritionally deficient, this can often be seen in its appearance.


Lack of nitrogen is expressed in the slow development of root crops. Foliage becomes darker, the formation of new leaves and the development of the root system is suspended.

Important! To compensate for the nitrogen deficiency can not make fresh manure, even in a diluted state.

An excess of nitrogen can be seen in the disproportionate development of the root - carrots build up large tops to the detriment of the root.


Phosphorus deficiency is externally expressed in a change in the color of the foliage of carrots; it becomes bluish. If fertilizer is not applied on time, the leaves dry up, the root crop becomes very hard.

Excess phosphorus in the soil can interfere with the absorption of other trace elements by the root system.


Lack of potassium slows down all processes in the plant, first change the color and dry the lower leaves of carrots, gradually all the foliage can dry out. Root becomes hard, inedible.

Excess potassium can slow the development of carrots, foliage gets a dark shade. Using natural sources of fertilizers, such as wood ash, it is impossible to obtain an excess of potassium.


If there is too little magnesium in the soil, foliage is the first to suffer, gradually, starting from the lower leaves, photosynthesis stops and the leaf dies. If the process affects a large number of leaves, the carrot will die.

It is difficult to get an excess of magnesium, it is impossible to overdose fertilizers with the recommended dosages.


An insufficient amount of boron prevents the formation of full leaves, tops grow small, undeveloped. The root system does not develop. An excess of this element is very rare.

Important! Carrots may not receive enough boron during the dry season if they are not watered.

Natural Sources of Fertilizers

Ready-made fertilizers can be replaced with natural products that will be excellent suppliers of nutrients. These fertilizers for carrots can be used for planting and during the growing season.

Weed grass

The mowed grass is placed in a large barrel, the size of 25 liters or more. Pour it with warm water, add ash, a glass of sugar and leave to ferment in a warm place. After 1-2 weeks, depending on the air temperature, the fertilizer is ready. Before use, it is diluted with warm water in a ratio of 1: 5. To handle one bed you need about a bucket of funds. You can use the infusion to fertilize the beds repeatedly, adding weeds and water. The frequency of processing carrot beds - once every two weeks.

Milk serum

Whey contains many beneficial substances that can improve the yield of carrots. To prepare a nutrient solution, wood ash is added to the whey; 0.5 liters of ash are required for 5 liters of whey. The resulting solution is diluted in water 1: 2, per square meter of beds will need 3-4 liters of fertilizer. Feeding is carried out twice a month.

Onion Husk

In addition to introducing nutrients, onion peel can protect carrots from its main pest - the carrot fly. A kilogram of husk is soaked in 5 liters of warm, clear water, add half a black bread and a glass of ash. After 3 days the fertilizer is ready. It is diluted with water, in a ratio of 1: 5, about 3 liters of finished fertilizer will be needed per square meter of bed. You can apply not only watering infusion, but also spraying it tops of carrots.


Well-fertilized beds are capable of producing a large, tasty carrot crop, if fertilizer is applied carefully and wisely. You must carefully observe the dosage and formulation when making nutrients.
