Ammonium hydrogen carbonate or bicarbonate, is a commonly used nitrogen fertilizer. Many farmers believe that the urea fertilizer ratio of ammonium bicarbonate is high, so at the time of fertilization choice rather than urea ammonium bicarbonate, in fact, in the winter or early spring cold season, using methods, both for potato, rape, wheat, vegetables and fruit trees, basal manure fertilizer or fertilizer, application of ammonium bicarbonate is better than urea. But there are many taboos in the process need to pay attention to the use of ammonium bicarbonate, today will try to understand.

Application of ammonium bicarbonate, has many advantages in production.
Nitrogen loss is small. The speed was positively correlated with the temperature of the high temperature decomposition of ammonium bicarbonate, the decomposition is faster, the greater the loss. At temperatures below 20 DEG C, less volatile, applied into the soil in a certain range of depth, the ammonium nitrogen is relatively stable, and is not easy to be adsorbed by soil colloid, with water loss, good preservation of nutrients for crops in the whole growth period. Urea under low temperature conditions, applied in the soil after the molecule dissolved in the soil solution, can not be adsorbed to soil particles, easily by water leaching with water movement, with the water loss caused by nitrogen.

The two is of high efficiency and fast. Ammonium bicarbonate large solubility even at 5 DEG C, fertilizer can also be absorbed by crops, so in the winter cold season, the application of ammonium bicarbonate can quickly be absorbed by crops. When the soil temperature is at 10 DEG C, after applying urea transformation requires 7 to 10 days, with the temperature decrease, urea transformation needs more time, so the low temperature season effect is far less than urea ammonium bicarbonate.
Three is the use of security. Does not contain ammonium bicarbonate ingredients, no adverse effects on soil after application. The release of carbon dioxide and ammonium bicarbonate decomposition also improve crop photosynthesis intensity, improve crop yield level.
Application of ammonium bicarbonate, to give full play to the effect, there are 6 points need to pay attention to taboo.
