Chemical formula: KNO3.
Complex fertilizer, which is used for soils with different composition and for a variety of cultivated crops.
It contains two main elements - potassium and nitrogen.
A characteristic feature of other potassium-containing chemicals is that this composition is the least harmful to the soil.
Potassium nitrate is often used to grow plants that are highly sensitive to chlorine.
Root top dressing:
Potatoes and vegetables: 30-50 g per 10 liters of water.
Other garden crops in the open field: 50-100 g of fertilizer per 10 liters of water.
If necessary, repeat watering with fertilizer after 7-10 days.
Outdoor crops: 10-20 g of fertilizer per 10 liters of water.
Greenhouse crops: 5-10 g of fertilizer per 10 liters of water.
Potassium and nitrogen are substances necessary for the active growth of plants: nitrogen affects the development and growth of green mass, and potassium is an essential element that promotes abundant flowering and fruiting, increased immunity, frost resistance and plant resistance to drought.
Potassium nitrate is used to improve the metabolic processes of the plant, as well as to optimize photosynthesis.
Potassium nitrate is used both as a basic fertilizer and for foliar top dressing for most types of vegetables, as well as for flower, ornamental and fruit crops.
The most favorable effect of fertilizer on crops such as: cabbage, potatoes, grapes, flax, onions.
Like most nitrogen-containing fertilizers, it is advisable to apply saltpeter to the soil in the spring, at the beginning of active plant growth (20 g per 1 sq.m).
Since this composition mostly affects active flowering and fruiting, it is not recommended to use it for feeding root crops (it will be enough to apply it as the main fertilizer to the soil in the spring before planting).
As a top dressing, potassium nitrate is applied from the beginning of the appearance of buds until the fruit ripens. Since the nitrogen content in the fertilizer is low, this is the best option for fruit trees.
Please note that, starting from the moment of flowering, other nitrogen-containing fertilizers cannot be used!
To feed plants, you should take 25 g of saltpeter and dilute it in 10 liters of water, watering is carried out depending on the condition of the soil and plants at intervals of 10-15 days.
With a deficiency of potassium, when a small number of buds are formed or the ovary develops poorly, foliar top dressing is used. Plants are treated with a potassium solution (25 g/15 L of water).
Potassium nitrate is highly soluble in water, so it can be used in mixtures. It is successfully used in hydroponics and drip irrigation.
Security measures: potassium nitrate is a strong oxidizing agent, so it can quickly react with various combustible substances and reducing agents, which is why it is so often used in pyrotechnics...
