How about big granule urea?
How about big granule urea? What are the characteristics? Hope that friends who know well can help introduce the differences between large granule urea and small granule urea in the agricultural material market. the particle size of small granule urea is about 1.5 mm, and the particle size of large granule urea is generally 2.00 mm to 4.75 mm. The characteristics of large granule urea are listed below for netizens' reference. The characteristics of large granular urea: special point 1, low dust content, high compressive strength, good fluidity, can be transported in bulk, not easy to break and caking, so it is suitable for mechanized fertilization. Special point 2, the dissolution rate of large granular urea is slightly slower after being applied into the soil, coupled with the larger single grain weight, the application in the paddy field can sink into the deeper soil and reduce the volatilization loss. Special point 3. Due to the different requirements of the processing process on the concentration of urine, the biuret content in general large granular urea products is reduced, which is beneficial to crops. Special point 4. Because of its large particle size, large granular urea has smaller specific surface area than small granular urea. In soil, the dissolution rate is slower and the fertilizer efficiency is higher, but it also makes its effective time smaller and urea particles longer. However, because the large granular urea particles are heavier, they can go deep into the deeper lower soil in the paddy field, the volatilization loss is reduced, and the fertilizer effect is more lasting and effective. Note: large granular urea can not be mixed with ammonium nitrate, sodium nitrate, ammonium bicarbonate and other highly hygroscopic fertilizers.
