The use of calcium nitrate( calcium nitrate) in the garden
Calcium nitrate is a chemical that can fertilize plants. In agriculture, it is usually referred to as calcium nitrate. There are other names for this substance: calcium nitrate, calcium nitrate, calcined or Norwegian. Used also in construction and other industries. Next, let's talk about the properties and application.
Content of a combination of nitrogen and calcium content
Composition and release form of calcium nitrate
Calcium nitrate belongs to the category of nitrogen mineral fertilizers. The composition is as follows. The amount of valuable substances varies from different manufacturers. Approximate indicators: nitrogen - 15%( from 11.6%), calcium - from 16 to 19%.
Urea is richer in nitrogen( 46%), as is ammonium nitrate( 34%), but they have no other useful components. Being less concentrated, calcium nitrate acts softer.
This drug is packaged in different companies in Russia. The retail garden stores and small wholesale bases most often include the brands “Bui fertilizers”( packaging of 1 kg, 25 g, 20 g), Fertika( 1 kg).Г
the storage period is usually indicated in the range of 1-2 years, , but the shelf life of such chemicals does not imply certain restrictions( in sealed packaging).
The substance dissolves well in water( especially in warm). Available in the form of snow-white rounded granules or crystals( like salt, sugar).The granular form is more convenient - it absorbs moisture from the air less. Crystals need to be stored strictly in a sealed package, otherwise they quickly dampen, bleed, slyaty.
The value of nitrogen and calcium complex
Nitrogen is the most important element in plant nutrition. But it is poorly absorbed with increased acidity of the soil. Many nitrogen fertilizers( urea, ammonium nitrate) acidify the substrate. Calcium nitrate manifests itself otherwise. It is important combination, the interaction of the two components.
Calcium promotes the penetration of nitrogen into plants. This is especially valuable in acidic and weakly acidic lands.
Most cultivated plants do not like high acidity. Calcium nitrate neutralizes or reduces it. The role of calcium in the life of the soil and plants is multifaceted. This element:
promotes the development of beneficial soil microorganisms, which improves the structure of the soil;
neutralizes harmful salts and metals, blocks their entry into plants;
stimulates the germination of tubers, bulbs and seeds in the soil;
activates the growth of root hairs;
strengthens the cell membranes of plants, helping to resist attacks of diseases and pests;
improves nitrogen absorption and other metabolic processes, chlorophyll synthesis;
helps the movement of carbohydrates, increasing the sugar content and other nutritional qualities of fruits, seeds;
increases crop yield and transportability.
Regular fertilizing with calcium nitrate on acidic soils reduces the incidence of vertex rot( tomatoes and peppers), kelp( cabbage, radish);give bright color to fruits( apples, etc.).
