Technical aqua ammonia (ammonia water) NH4 OH is a highly assimilable liquid fertilizer.
Aqueous 25% and 22% ammonia solution is produced in two grades – with a nitrogen content of 20.5 and 18%. Colorless or yellowish liquid with a sharp odor (ammonia). The vapor pressure is small.
Liquid nitrogen fertilizers are applied by special machines that ensure their immediate penetration to a depth of at least 10-12 cm on heavy soils and 14-18 cm on the lungs. The superficial application of these fertilizers is unacceptable, since ammonia rapidly evaporates. With a smaller embedding, significant losses are also possible, especially on light sandy and sandy loam soils. From the moist soil the loss of ammonia is much less than from the dry one.
Ammonia nitrogen is better retained by the soil than ammonium nitrogen of solid fertilizers.
The influence of ammonia water on the yield is not inferior to solid ammonium nitrate fertilizers, and even surpasses them in arid years.
Thanks to the instant assimilation of water-soluble nitrogen by plants, water ammonia is an economic and effective liquid fertilizer, and at the same time contributes to pest excretion.
Сonsidering the fact that ammonia water is a toxic liquid that can damage the mucous membrane of the eyes and the respiratory tract, while working with it, you must strictly adhere to the safety rules “when working with dangerous goods”, the rules of labor protection.
The disadvantage is its low transportability (80% of water), special machines for soil application and packaging for storage and transportation. It is more economical to use it in farms located near the producers of this type of fertilizer.
Low cost and high efficiency of nitrogen contained in it are essential advantages of this fertilizer. According to some reports, the effect of ammonia water on winter rye, barley, potatoes, corn is close to the effect of ammonium nitrate.
