The commonly used nitrogen fertilizers are classified into four types: ammonium, nitrate, ammonium nitrate and amide nitrogen fertilizers. In the past 20 years, a new type of long-acting nitrogen fertilizer (or slow-acting nitrogen fertilizer) has been developed. Long-acting nitrogen fertilizers include both fully organic nitrogen fertilizers and coated nitrogen fertilizers. The main varieties of various types of nitrogen fertilizers are as follows:
(1) Ammonium nitrogen fertilizers include ammonium sulfate, ammonium chloride, ammonium bicarbonate, ammonia, and liquid ammonia;
(2) Nitrate-nitrogen fertilizers include sodium nitrate and calcium nitrate;
(3) Nitrate ammonium nitrogen fertilizers include ammonium nitrate, calcium ammonium nitrate and ammonium sulfate nitrate;
(4) Amide nitrogen fertilizer has urea, calcium cyanoaminate (lime nitrogen).
