Appearance is white crystal, easily soluble in water and easy to decompose. Ammonium bicarbonate is suitable for all kinds of crops and soils. Pure products can be used in food industry to make bread and biscuits. It is also used in pharmaceutical industry, electroplating industry and manufacturing rubber shoes sponge soles.
Generally speaking, when the temperature is around 10℃, ammonium bicarbonate basically does not decompose, but it begins to decompose in large quantities at 20℃. When the temperature exceeds 60℃, ammonium bicarbonate decomposes violently and its shape is uncertain. Therefore, care must be taken during storage and transportation.
Introduction to fertilizer history
China knew as early as the Western Zhou Dynasty that weeds rotted in the fields could promote the growth of millet. The method of planting green manure and the method of rotation between leguminous crops and gramineous crops are introduced in detail in Qi Yao Min Shu. The method of mixing, trampling and composting crop straw with cow dung and urine is also mentioned.
In terms of fertilization technology, Fan Sheng Zhi Book has a detailed description, emphasizing the importance of applying sufficient base fertilizer and topdressing to crop growth. After the Tang and Song Dynasties, with the popularization of rice in the Yangtze River basin, fertilization experience accumulated day by day, thus summing up the principle of "timely fertilization, suitable soil and suitable material", that is, fertilization should be determined according to the changes of climate, soil and crop factors.
With the rise and development of modern chemical industry, various chemical fertilizers have come out one after another.
