When applying nitrogen fertilizer to crops in the winter and spring low temperature season, it is preferable to use ammonium bicarbonate. After the ammonium bicarbonate is applied to the farmland, it can be directly absorbed and utilized by the crop without conversion, and the nitrogen can be supplied in time, and the yield increasing effect is good, and the urea should be left in the hot season. Tests have shown that when the temperatures are 5 ° C, 10 ° C and 20 ° C, the conversion of urea takes 15 days, 7 to 10 days and 4 to 5 days, respectively. In winter and spring, due to the lower temperature, ammonium bicarbonate is just the longest in this respect. The soil colloid has a strong adsorption capacity for ammonium bicarbonate, which is 9.09 to 12.5 times that of urea. Under low temperature conditions, the volatilization loss is small, and it is wet. The rate is also small, only about 1/3 of urea.

FAG Bearing
Before using,you can make a single judge by observing,touching & easily testing.
Does it look glossiness?Does it feel smooth?Does it make any noise?
A high quality Deep Groove Ball Bearing must be hypefine grinded with smooth surface, no burrs on the edges,running fast &noiseless, that is the feature of our products.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing
types.
