Urea is easily soluble in water, and when dissolved in soil, it is converted to ammonium bicarbonate by the action of urease secreted by microorganisms. This conversion is faster at higher temperatures and suitable moisture. The crop can absorb and utilize ammonium nitrogen and ammonium nitrogen. It can also be adsorbed by soil colloids and it can also become ammonia loss under alkaline conditions. The unhydrolyzed urea, due to its neutrality, is not easily adsorbed by the soil and is easily lost. For these characteristics of urea, the effectiveness of urea can be improved by some measures.
(1) Urea should be applied deeply, which is not only beneficial to the conversion of urea, but also can reduce the volatilization loss of urea after it is converted into ammonium carbonate, but it must not be too close to the root system to prevent ammonia damage. Urea deep application is not suitable for leaching Large, low-nitrogen sandy soils are also not suitable for soils with low urease levels or low activity.
(2) When urea is used as rice basal fertilizer or top dressing, the characteristic of large initial fluidity is considered, and irrigation is not performed immediately after application, and water is irrigated when it is converted into ammonium nitrogen for several days.
(3) Do not apply too much urea once in the sandy soil and cause loss.
(4) The urea is made into granular and large granular application, which can make the fertilizer effect long, reduce the loss, and can also be made into a long-acting coated fertilizer.
(5) Urea can be combined with nitrification inhibitors to prevent the leaching of ammonium nitrogen nitrification, and can also be used with urease inhibitors to slow the hydrolysis of urea.
Here are general instructions on how to use a Nebulizer:
Put the compressor on a flat surface where it can safely reach an outlet.
Check to make sure all the pieces are clean.
Wash your hands before prepping the medication.
If your medication is premixed, place it in the container. If you need to mix it, measure the correct amount, and then place it in the container.
Connect the tube to the compressor and the liquid container.
Attach the mouthpiece or mask.
Turn on the switch and check to see that the nebulizer is misting.
Put the mouthpiece in your mouth and close your mouth around it or put the mask securely over your nose and mouth, leaving no gaps.
Slowly breath in and out until the medicine is gone. This may take five to 15 minutes.
Keep the liquid container upright throughout the treatment.
