Small granular urea is suitable for various soils and various crops. It is a nitrogen fertilizer containing high nitrogen nutrients and can be applied as base fertilizer and top dressing. The speed of the ammoxidation process of small particles of urea is related to the moisture, temperature, organic matter content and pH in the soil, and is also affected by factors such as soil type and fertilization depth. Because our company's small granular urea plus slow release agent, the total ammoniation time is longer than ordinary urea, and the fertilizer efficiency is longer than ordinary urea. Therefore, farmers should use it 3 to 5 days earlier than normal urea. When the small granular urea is used as the base fertilizer, the dry land is applied before the tillage. When the tillage is turned over, the urea is deeply buried in the soil, and the effect is better with the farmyard manure; the paddy field can be used to treat urea and farmyard manure before the cultivated land. Apply together, then plow the soil, and then irrigate after 2 to 3 days. If there is water in the paddy field, do not release water after applying urea to prevent the fertilizer from lowering. When using small granular urea as a top dressing, it is best to apply it or apply it as a hole. Try not to spread it. If it is not possible to apply it or apply it, it is best to apply it before and after the rain and when the soil is wet. When using it as a green fertilizer, the dosage should not be too much. There is also a certain increase in production when topdressing is done outside the roots. Small granular urea should be used for foliar fertilization, and its concentration is generally 0.5-2%.
Small granular urea can be mixed with farmhouse manure such as soybean cake, human excrement, compost, and manure, but due to the action of the emblem, it will accelerate the urea ammoniation. Therefore, when mixed, it must be used with the mixture, and it should not be mixed for a long time. So as not to cause loss of fertilizer efficiency. It can also be mixed with weak hygroscopic fertilizers such as potassium chloride, carbon nitrogen, calcium superphosphate and calcium chloride, but it should be used immediately after mixing and should not be stored for too long. It can also be mixed with ammonium sulfate, potassium sulfate, plant ash, lime, phosphate rock fertilizer, calcium magnesium phosphate fertilizer, etc. Since the above fertilizer varieties are basically non-hygroscopic, they can be mixed at will. Small particle urea cannot be mixed with highly hygroscopic fertilizers such as ammonium nitrate, sodium nitrate or ammonium hydrogencarbonate.
