The benefits of nitroammophoska for tomatoes
Tomatoes are a capricious culture. For good development, they require feeding. Nitroammophoska for tomatoes is one of the best fertilizers. Its use helps to strengthen plants and achieve high yields, and also improves the taste of fruits and increases their immunity to rust and powdery mildew.
The benefits of nitroammophoska for tomatoes
Description of the drug
Nitroammofoska is a complex product that contains nitrogen, phosphorus and potassium. Each of these elements is essential for tomatoes at different stages of development. They are produced in the form of light gray granules. They are used dry or solutions are prepared on their basis. The fertilizer is characterized by a fast action, since the elements contained in it have an easily accessible form for assimilation by plants.
There are different types of drug. The main components in it do not change, but their ratio varies. Manufacturers adjust the composition of the product for different types of soil, therefore, its zoning arose. A popular brand of fertilizer is NPK 16:16:16, which contains the main active ingredients in equal proportions (16%). If the soils are poor in phosphorus and potassium, a ratio of 8:24:24 is suitable. When there is a lot of mobile phosphorus - 21: 0.1: 21 or 17: 0.1: 28.
Benefit
Nitroammofoska has a healing effect on tomatoes. They are less sick with scab, root and stem rot, late blight. Fruits, thanks to potassium, which is responsible for the production of sugars, become sweeter.
Benefits
Nitroammofosk is characterized by the following qualities:
- preservation in a crumbly form throughout the shelf life;
- high efficiency;
- versatility: it is used on various soils and for any plantings;
- excellent solubility;
- active substances constituting at least 30% of the total mass;
- acceptable price;
- ease of transportation.
disadvantages
The disadvantages include:
- accumulation of nitrates in the soil with incorrect dosage of the substance;
- short-term preservation - no more than six months, after this time, the qualities of the product are lost;
- danger (level 3) - granules can explode and ignite.
Site preparation
The soil must be prepared for planting
The drug is most successfully used on chernozems and sierozems. On these types of soil, high results are noted in increasing productivity indicators, provided that there is good moisture.
On chernozems and on clayey soils, nitroammofosk is applied in the fall. If the land is characterized by a light structure, it is improved in the spring. This is due to the fact that chemicals in heavy soils penetrate into the fertile layer over a long period.
The brand of the product is selected for the soil warehouse. For 1 sq. m evenly distribute 40 g of granules, dug up. For uncultivated land, the consumption is increased to 50 g or more. When preparing a mixture for filling a greenhouse for 1 cu. m of soil give 1.5 kg of the drug, with subsequent treatments - 60 g per 1 sq. m.
Often the tool is used in areas where the bear is rampant, since organic substances contribute to the reproduction of the pest. The drug does not differ in this property, and the effect of its use is identical.
Top dressing of tomatoes with nitroammophos
The product is used to fertilize tomatoes at different stages of growing.
Fertilizing seedlings
Seedlings, before planting in a permanent place, need 2 times the introduction of nutrients:
- On the 12th day after the pick, use the following remedy: 1 tsp. urea per 10 liters of special fertilizer solution, the concentration of which is reduced by 2 times compared to the recommended dose.
- A week after the previous feeding, apply the following solution: 1 tsp. ammophoska or nitroammofoska for 10 liters of water.
If the plants do not develop well, the feeding is repeated every 2 weeks. It is produced in the same way as in the second stage.
Tatiana Orlova (Candidate of Agricultural Sciences):
Usually, when preparing seedlings, other fertilizers are used - water-soluble. Nitroammophoska dissolves for a long time. Therefore, when growing seedlings, such water-soluble fertilizers as Aquarin, Solvent, Kristalon are used, which dissolve in water in a matter of seconds.
Fertilizing adult plants
More often nitroammofoska is used for tomatoes after planting in open ground. It accelerates plant growth and fruiting times. It is brought in according to the following scheme:
- The first time is 10-15 days after the transplant. For this purpose, prepare the following solution: 1 tbsp. l. preparation for 10 liters of water. Consumption - 0.5 liters of liquid for one bush. Such fertilization promotes good adaptation of plants in a new place, and also accelerates their growth. The NPK 16:16:16 brand will do.
- The second time - 3-4 weeks after the previous one. For feeding, nitroammofoska is combined with cow dung: 1 tbsp. l. and 0.5 kg. The mixture is diluted in 10 liters of water. Consumption - 0.5 l of the product per plant. In this and in the following periods, a drug with a high dosage of potassium is used.
- The last time - in the growth phase of the third cluster of tomatoes. Watering is carried out with this solution: 1 tbsp. l. nitroammofoski, 1 tbsp. l. sodium humate, 10 liters of water. The specified amount is applied per 1 sq. m landings.
The drug is also used when tomatoes do not set fruit well. Often they are mixed in equal proportions with other products. It can be superphosphate, potassium sulfate.
Tatiana Orlova (Candidate of Agricultural Sciences):
Fertilizers are applied only on wet soil, i.e. after watering, but never on dry ground. Can cause root burns.
Precautions
The substance is stored at a temperature not exceeding 30 ° C in rooms made of concrete or brick. Air humidity should not exceed 50%. No open flame devices are used in the storage area. Do not keep other drugs nearby to avoid a chemical reaction.
After the expiration date, the product becomes more explosive and fire hazardous. It is transported only by land transport.
Conclusion
So that too many nitrates do not accumulate in tomatoes, they strictly adhere to the dosage of the substance, and also stop its introduction in advance. There are means that have a similar effect on the culture: azofosk, ammofosk, nitrophoska. Sometimes they replace nitroammophoska.
