Parsley is very useful and not whimsical greens to grow. Absorbing nutrients from the soil, it reproduces various vitamins, minerals, phytoncides.
In order to create ideal conditions for the growth of greenery, it is enough to know how to properly fertilize the soil and how to feed it for growth after winter.
From this article, you will learn about how to feed parsley and at what time it needs it most. And also from what you can prepare the fertilizer yourself and what can be threatened by non-compliance with the dosage when feeding this plant.
Why is it so important?
Plant feeding is necessary:
- for its proper growth and development;
- strengthening the root system;
- formation of a sheet apparatus;
- maintaining water balance;
- strengthening immunity;
- disease prevention.
The soil used for growing greenery in pots or greenhouses especially needs to be enriched with nutrients, because the reserves of macro- and microelements in the soil sooner or later dry up. So, parsley needs:
There is a slight difference in fertilization for leaf and root parsley.: Root greens cannot be grown using organic feeding, this is fraught with a change in taste and root stratification.
When is it especially in need of fertilization?
In order to get healthy and tasty greens, it is necessary to fertilize parsley throughout the growing season; you also need to prepare the soil before planting. If the plant grows poorly and becomes lethargic, the leaves turn yellow or fall off, additional feeding can be done.
Important! You can not feed the plant in case of illness, it is recommended to first find out the cause and eliminate it.
Top dressing before and after planting - what's the difference?
In the fall, the soil is fed in order to prepare it for the new season, because during the winter period the soil rests, the useful components have time to be processed. It is enough to carefully dig up the soil and add about 5 kg / m² of humus.
In the spring, careful preparation begins before planting - it is necessary to fertilize the soil with complex mineral fertilizers. For the cultivation of leaf parsley, saltpeter is applied, for root varieties, phosphorus-potassium fertilizers.
How and what to fertilize: step by step instructions
Fertilizer consumption rates, depending on the manufacturer, will be different... Consider the general norms of the amount of fertilizers in different seasonal periods.
In the spring
- Fertilizers are placed in rows.
- Next, about 2 cm of soil is poured.
- Seeds are sown from above.
- You can also apply fertilizer to additional furrows located at least 2 cm from the main seed furrow.
Several types of fertilizers are used in the spring.:
- Superphosphate is a phosphorus-nitrogen complex that helps the growth and development of the root, trunk and leaves of the plant and provides protection against many diseases.
Attention! Superphosphates cannot be used simultaneously with urea, ammonium nitrate and lime, as they neutralize the beneficial properties of the fertilizer.
Regardless of the season, the fertilizer consumption rate remains the same - 40-50 g / m² for cultivated land, and 55-70 g / m² - for those already participating in the crop rotation (recommended dosage for continuous application).
- Nitrogen fertilizers - ammonium sulfate in granules (25-30 g / m²), the beds are pre-dug, then watered with a solution of ammonium sulfate; then the seeds are planted (read about growing parsley from seeds here, and about growing seedlings described here). Top dressing is done once.
- Ammonium nitrate - the dosage is calculated depending on the condition of the soil. If it is depleted, 35-50 g / m² is recommended; cultivated soil is sufficient 20-30 g / m². When the first shoots appear, fertilize at the rate of 10 g / m²; after two weeks feeding is repeated 5-6 g / m².
- In order to form a rich leaf in parsley, you can give top dressing from 15 g of superphosphate, 35 g of ammonium nitrate, 10 g of potassium sulfate.
- In addition to the above, in the spring, you can use complex fertilizers with the participation of the entire complex (from nitrogen, potassium and phosphorus):
- ammophos 15-25 g / m²;
- diammonium phosphate grade B 15-25 g / m²;
- fertilizer nitrogen-phosphorus-potassium grade NPK-1 25-30 g / m².
Top dressing of parsley in summer is required periodically throughout its active growth.
- Root dressing... 1 top dressing (nitrogen, phosphorus and potassium):
- ammonium nitrate grade B 20-30 g per 10 liters of water / m²;
- granular superphosphate 15-20 g / m²;
- potassium magnesium 20-25 g / m².
Fertilizers are applied after cutting the greenery. Then you can use molybdenum, manganese micronutrient fertilizers.
- Foliar dressing:
- calcium nitrate 4-water 15-20 g per 10 liters of water;
- urea grade B 30-60 g per 10 liters of water (recommended only for leaf grade).
Feed 4 times with an interval of 2-3 weeks.
- Microfertilizers are used:
Parsley is highly susceptible to organic fertilizers (except for the root variety). They can be worn under leaf parsley both in autumn and in spring - compost or humus at the rate of 4-5 kg / m². It is recommended to apply manure only in autumn. For autumn digging, the soil is fertilized with mineral fertilizers:
- superphosphate 40-50 g / m²;
- potassium magnesium 30-40 g / m².
Superphosphate is carried into the soil in late autumn after the harvest is complete, so that phosphorus can be absorbed by the soil during the winter. You can't just scatter fertilizer on the ground, otherwise it will simply be washed away by the rains; superphosphate should be located in the ground itself, near the roots of plants.
It is recommended to wear potash salt after harvest or in early spring, in the amount of 20 g / m².
In winter, only parsley, grown at home or in industrial greenhouses, needs feeding. You can focus on the summer feeding method.
In addition to store fertilizers, top dressing can be prepared independently from nettle:
- To prepare the nettle infusion, it is necessary to collect the young shoots of the nettle (without seeds).
- Place in a large container (half full) and do not completely fill it with water.
- Close the lid tightly, leave for several weeks.
- The resulting dark liquid (without bubbles) is diluted with water 1:20 and sprayed with parsley.
Such feeding will protect parsley from pests and diseases, nourish plants well and heal the soil.
Why is it important to follow the dosage?
It is very important to adhere to the exact dosage of fertilizers, otherwise the plant may react adversely to the excess / lack of nutrients. With a lack or complete absence of fertilization, the plant shows the following symptoms:
- retardation of plant growth (nitrogen, manganese, molybdenum, boron);
- thinning of branches (nitrogen, manganese);
- decreased leaf brightness, yellowness (nitrogen, potassium, magnesium, iron);
- decrease in leaf juiciness (phosphorus, molybdenum);
- the appearance of brown spots (calcium);
- drying of leaves (phosphorus);
- chlorosis (nitrogen, magnesium);
- light spots on the leaves, dying off of the tops (copper, zinc).
With an excess of fertilizers,:
- fungal diseases, chlorosis (nitrogen, calcium);
- weakening of the plant (nitrogen, calcium);
- growth retardation (potassium, copper);
- overgrowth with thinning of leaves and stem (phosphorus);
- weakening of the root system (magnesium, copper);
- leaf fall (iron, zinc, boron);
- brown spots (manganese, copper, boron);
- light spots on the leaves (molybdenum).
In most cases, with the correct recognition of the cause of a particular symptom in a plant, it is enough to remove / add the necessary nutrient.
With proper care, parsley is bound to produce a rich and flavorful harvest. It is enough to remember the main rule: it is better to "underfeed" the plant than "overfeed"... If, with a slight lack of feeding, parsley only loses a small part of its nutrients, then with an excess of fertilizers, it can harm human health and the environment.
