In the winter and spring cold seasons when applying nitrogen fertilizer to crops, ammonium bicarbonate is the best choice. After the ammonium bicarbonate is applied to the farmland, it can be directly absorbed and utilized by crops without conversion. Nitrogen can be supplied in time and the effect of increasing production is good. Urea should be used in the high temperature season. Tests have shown that urea conversion takes 15 days, 7 to 10 days and 4 to 5 days, respectively, when the temperature is 5°C, 10°C and 20°C. Due to the lower temperature in winter and spring, ammonium bicarbonate is just long in this respect. Soil colloids have a strong adsorption capacity for ammonium bicarbonate, which is 9.09 to 12.5 times higher than that of urea. Under low temperature conditions, the volatilization loss is small and the rate of wetting is small. Only about 1/3 of urea.
