What is the difference between urea and fertilizer
Urea is the most common and common chemical fertilizer, but chemical fertilizers are not only urea, but inorganic fertilizers are all chemical fertilizers.Compound fertilizer and urea are both large fertilizers in the fertilizer market. Compound fertilizer is a chemical fertilizer containing a variety of elements, which can supplement a variety of nutrients needed by crops and balance the nutrients needed for crop growth.
Urea is one of the chemical fertilizers. Urea is a nitrogen fertilizer. It contains nitrogen and is a kind of nitrogen fertilizer with a relatively high nitrogen content.There are many types of fertilizers, mainly nitrogen fertilizers, potash fertilizers, phosphate fertilizers, and compound fertilizers.Those that contain nitrogen are called nitrogen fertilizers, those that contain phosphorus are called phosphorus fertilizers, those that contain potassium are potassium fertilizers, and those that contain three or more nitrogen, phosphorus and potassium are compound fertilizers.So urea is a fertilizer, but fertilizer is not necessarily urea.Urea contains only a single nitrogen fertilizer and is mainly used as a top dressing for crops. The difference from other traditional top dressing such as urea is that urea is a quick-acting fertilizer, which is absorbed by crops faster, but the duration of the effect after application is relatively short, and it is only suitable for the peak fertilizer demand during crop growth.
There are many types of nutrients in compound fertilizers. One application of compound fertilizers can supply at least two or more main nutrients of crops at the same time.For example, ammonium phosphate does not contain any useless side components, and its anions and cations are the main nutrients absorbed by crops.The nutrient distribution of this kind of fertilizer is relatively uniform. After forming particles, compared with powdered or crystalline unit fertilizers, the structure is tight, the nutrient release is uniform, and the fertilizer effect is stable and long.Due to the small number of by-components, it has little adverse effect on the soil.
