In 2024, 15 major Chinese commercial reserve and trading companies, including Sinoagri and Sinochem, signed a voluntary agreement on urea exports. According to the agreement, these companies agreed that the total urea exports in 2024 would not exceed 944,000 tons. This voluntary agreement reflects the Chinese government's intention to control the total amount of urea exports.

On the other hand, the actual export situation in the first half of 2024 showed that despite several rumors of loosening of exports, the actual export volume was very limited under the guidance of the national policy of ensuring supply and stabilizing prices. The actual export volume in the first half of the year was only 75,400 tons, a year-on-year decrease of 92.53%. This data reflects the actual restrictive effect of the policy on exports.

In summary, the urea export policy in 2024 reflects the Chinese government's strict control over urea exports through voluntary agreements and restrictions on actual export volumes, aiming to stabilize domestic market prices and meet domestic demand.

There are a few points to note about the use of urea:

1, Do not spread it directly on the ground, and do not use it when the soil is dry, otherwise a large amount of nutrients will evaporate and be lost in vain, or the ammonia volatilized by urea will cause seedling burn. If urea is spread in the field, the agricultural technology backpack recommends that you spread it before the rain. The rain here refers to a light and moist rain, not a heavy rain. A light rain can bring urea into the soil, and a heavy rain will only wash the urea into the ineffective deep soil.

2, Do not irrigate immediately after fertilization, otherwise a large amount of nutrients in urea will be lost to the soil below the tillage layer with water and reduce the fertilizer efficiency. The correct way to use it is to use it when the soil in the field is moist. When applying fertilizer, cover the urea with soil and apply it to a deep soil of 15-25 cm. In short, urea should be used deep rather than shallow.

3, It is recommended to use urea about 6-8 days in advance in winter and early spring low temperature seasons, about 2 days in advance in summer high temperature seasons, and about 3-4 days in advance in warm spring and autumn seasons.

4, Do not use excessive urea, otherwise it is easy to cause a large amount of fertilizer waste, and it is also easy to cause excessive growth of crops, a large number of lodging, burning roots and seedlings, increased pests and diseases, and reduced yields and quality.

5, When using urea, it can be mixed with acidic fertilizers such as potassium sulfate and superphosphate (the fertilizer efficiency is not reduced), but it is not suitable to mix it with alkaline fertilizers such as calcium magnesium phosphate and wood ash, otherwise the nitrogen in the urea will be converted into ammonia and volatilized and lost. When urea is used with alkaline fertilizers, it is recommended to use them separately at an interval of 5-7 days.
