Product Description

Carbamide (urea) - chemical formula H2N-CO-NH2, excellently soluble in water, alcohol, liquid ammonia and sulfur dioxide. In industry, urea is synthesized from ammonia and carbon dioxide via reaction Bazaroff. That is why the urea production often combined with production of ammonia.

Urea contains about *6% nitrogen, thus being the most concentrated nitrogenous fertilizers. The fertilizer is available in two grades A and B. Grade A is designed for industrial use, grade B - for agriculture. The substance is soluble in water and is excellent in storage does not cake. Suitable for all soil types as the basic and presowing fertilizer and also as a dressing.

Efficiency of urea used as a basic fertilizer, is not inferior to the well-known all ammonium nitrate. At the same time, it contains the highest amount of urea nitrogen, which ensures a high feasibility of its use.

Urea is also used as a foliar application of vegetable, fruit and late fertilizing wheat, aimed at increasing the protein content in the finished grain. Urea is valuable because in contact with the plant is no burn, and therefore does not harm the leaves. This quality provides excellent digestibility fertilizer. At the same time, when applied to the soil surface, urea should immediately be stopped, in order to prevent the loss of nitrogen due to volatilization of ammonia.

When using urea in acidic soils is recommended for each quintal of fertilizer use as an additive 0,8ts calcium carbonate. Just urea phosphate can be mixed with flour or superphosphate. It is worth noting that the urea is extremely resistant to leaching, which is especially important for irrigated agriculture. The fertilizer can be introduced into the soil in solid form or in the form of liquid solutions with other nitrogen fertilizer.

The most commonly used urea as a fertilizer for potatoes, sugar beet and vegetable crops.

Wheat, rye, oats: basic introduction rate of ******0 kg per 1 hectare.
Sunflower: about *****0 kg per 1 hectare.
