Nitrogen-carbonate-magnesium fertilizer. It is advisable to use on soils with increased acidity (sod-podzolic, gray forest, etc.) in the conditions of Polissia and the western part of the Forest Steppe of Ukraine. Lime-ammonium nitrate does not acidify the soil, which is due to its neutral reaction, thanks to these features it is widely used in world agriculture.
Such crops as: sugar beets, fodder, table, winter and spring wheat,
corn, barley, winter and spring rapeseed,
sunflower, soybeans, peas, fodder beans, clover, alfalfa, asparagus respond well to feeding with lime-ammonium nitrate. cabbage, onions, cucumbers and other plants that require a slightly acidic soil reaction (pH 6-6.8-7).
It is applied to all agricultural crops superficially or locally during the main application and for root top dressing with mandatory wrapping in the soil.
In terms of physical and chemical properties, it has the following indicators:

Nitrogen is the most important biological element, which is a component of all proteins and amino acids, nucleic acids, chlorophyll, alkaloids, many vitamins, hormones and other biologically active compounds. All enzymes that catalyze metabolic processes in plants are protein substances.
Magnesium - participates in the process of photosynthesis, is a part of chlorophyll, and plays an important role in the activation of enzymes responsible for the entry and movement of phosphorus in plants. With magnesium deficiency, plant chlorosis is observed and growth stops.
Calcium - contributes to the transportation of carbohydrates in plants, improves the solubility of many compounds in the soil, promotes the absorption of important nutrients by plants. Calcium and magnesium strengthen cell walls and bind them to each other, promote the development of the root system, are necessary nutrients.
An acute deficiency of this element is manifested in the formation of whitish leaves on the upper young parts of plants and the loss of turgor of the upper leaves and stems. Even in
potatoes, resistant to excessive acidity of the soil, the upper leaves hardly open, the growth point of the stem dies.
