Correct application methods for ammonium-nitrogen compound fertilizer
How should ammonium-nitrogen compound fertilizer be applied? Please give an introduction. There are three types of nitrogen fertilizer in compound fertilizer: ammonium nitrogen, nitrate nitrogen and urea. Nitrate nitrogen is absorbed most quickly by crops, but it is not easily retained in the soil and is prone to leaching with water, so it is best used as a top dressing and less suitable as a base fertilizer; urea also leaches easily, and after being applied to the soil it must undergo transformation before it can be absorbed by crops. This process takes a long time when spring soil temperatures are low, and its effect is too slow, so it is also not ideal as a base fertilizer. Only ammonium nitrogen is both easily adsorbed and retained by the soil, not prone to leaching, and unaffected by low temperatures, giving it the highest utilization rate and making it the most ideal base fertilizer. Therefore, ammonium-nitrogen compound fertilizer is suitable for application as a base fertilizer.

What should be noted when applying nitrogen fertilizer? A detailed explanation of the key points for using various types of nitrogen fertilizer
What should be noted when applying various nitrogen fertilizers? Please introduce the following points to note when applying various nitrogen fertilizers: 1. Ammonium nitrogen fertilizers should not be mixed with alkaline fertilizers. After mixed application, ammonia gas will volatilize, reducing the fertilizer effect. 2. Ammonium bicarbonate should not be broadcast. Ammonium bicarbonate is extremely unstable in nature, and after being broadcast on the soil surface, under...

Is it okay to apply only nitrogen fertilizer as base fertilizer in autumn and winter?
Is it okay to apply only nitrogen fertilizer as base fertilizer in autumn and winter? Please give an introduction. Some farmers are in the habit of applying 80-100 kg of ammonium bicarbonate or 60-80 kg of urea per mu when sowing autumn and winter crops. This method of applying only nitrogen fertilizer often causes some adverse consequences. First, it reduces the utilization rate of chemical fertilizer. Applying too much ammonium bicarbonate and urea...

What are the nitrogen fertilizer application methods for fruit crops?
How should nitrogen fertilizer be applied to fruit crops? An introduction is given that the sweetness of fruit is determined by the amount of sugar in its cells, and the accumulation of sugar is closely related to nitrogen fertilizer. Therefore, it is said that the sweetness of fruit is related to nitrogen fertilizer. Within 28 days from the end of flowering of the fruit tree to after the end of flowering, the cells of the young fruit are in a state of division, and the cells are filled...
