How to identify fake urea 46-0-0 nitrogen fertilizer? Remember these points!

Urea 46-0-0 nitrogen fertilizer has high nitrogen content and good solubility. It is currently a neutral fertilizer with a high nitrogen content. It is widely used in agricultural production. Summer is the fastest growing season for crops, especially summer corn, which has also entered the topdressing period. Urea 46-0-0 nitrogen fertilizer is very popular among farmers due to its low price and good rapidity. There are many products on the market, and it is difficult for farmers to distinguish between the real and the fake. Which urea 46-0-0 nitrogen fertilizer is real? Today, I will teach you how to identify it.

Main features of urea 46-0-0 nitrogen fertilizer

Urea 46-0-0 nitrogen fertilizer is a fertilizer that only contains nitrogen. The nitrogen content is 46%. It is the fertilizer with the highest nitrogen content among nitrogen fertilizers. It has stable physical and chemical properties. The pure product is white or slightly yellow crystals or small particles. It has an anti-humidifier, low hygroscopicity, not easy to agglomerate, and easily soluble in water. It is a neutral nitrogen fertilizer. It is suitable for various soils and a variety of crops. It is most suitable for topdressing, especially foliar topdressing, with higher utilization rate and best effect.

Remember the following points when purchasing

(1) Do not buy urea containing "sulfur" "zinc" "multi-micro"

There is a kind of urea on the market, called sulfur-containing urea, which claims to supplement sulfur and zinc. Urea, also known as carbon amide, only contains nitrogen, carbon, oxygen and hydrogen, and does not contain any sulfur, zinc, or trace elements. Therefore, urea mainly marked as containing "sulfur" must be fake urea, so do not buy it.

(2) Do not buy urea containing "organic" urea
There is another type of urea on the market, called "organic" urea, which is advertised as containing "organic matter". When applying urea, it can also supplement organic matter such as amino acids. However, the implementation standard of this product is not the urea standard. Fertilizers containing organic matter are called organic-inorganic compound fertilizers. Therefore, organic urea containing organic matter is not urea at all.

(3) Do not buy urea containing "humic acid"
Some fertilizers have "humic acid" urea written on the packaging bag. In fact, these are not urea, but should be called humic acid fertilizers.

(4) Do not buy "polypeptide" urea.

Urea quickly decomposes into ammonium carbonate or ammonium bicarbonate when it comes into contact with water and is absorbed by crops in the form of ammonium ions. Polypeptides are broken-chain proteins. Urea does not contain any amino acids and does not contain polypeptides.

Requirements for qualified urea 46-0-0 nitrogen fertilizer:

1) The packaging bag only indicates the nitrogen content, which is N=46%, or the nitrogen content is 46%, without any other nutrient content.

2) The granules are white or light yellow round granules. The color is uniform and there is no crumbs.

3) When the packaging bag is opened, there is no ammonia smell or other odor.

4) Implementation standard: The implementation standard on the packaging bag is GB/T 2440-2017.

5) The manufacturer's name, address, telephone number and other information must be complete.
