Do not apply water immediately after applying urea. More avoid water spreading urea. Urea is applied to soil and converted into amide, which is easy to run off with water. It cannot be watered immediately after application, nor can it be applied before heavy rain. After application, the soil can improve fertilizer efficiency. In addition, the phosphate fertilizer should be concentrated and not spread to prevent it from being fixed. It is best to apply it in the ditch or in the vicinity of the root system. The rare earth micro-fertilizer is applied directly to the soil but it should be used as a seed fertilizer or foliar fertilizer.
Ammonium bicarbonate and urea cannot be mixed. The amide nitrogen in urea can not be absorbed by crops. It can only be used by crops after being converted into ammonium nitrogen by the action of adenosine in the soil. After carbon iron is applied to the soil, the soil solution will be acidic in the short term and accelerate. Because of the loss of nitrogen in the urea, it cannot be mixed. Ammonium bicarbonate can not be mixed with bacterial fertilizer, because the former will emit a certain concentration of ammonia gas, which is toxic to the active bacteria of the latter, will make the fertilizer lose its fertilizer effect.
Acidic fertilizers cannot be mixed with alkaline fertilizers. Ammonium bicarbonate, ammonium sulfate, ammonium nitrate, and ammonium phosphate cannot be mixed with alkaline fertilizers such as grass ash, lime, and kiln ash, and a neutralization reaction may occur, causing loss of nitrogen and reducing fertilizer efficiency.
Nitrogen compound fertilizer should not be applied to legume crops. Soybeans, mung beans, peanuts and other legumes have nitrogen-fixing rhizobia. Too much application of nitrogen-containing compound fertilizer will not only cause waste, but also inhibit the activity of rhizobia and reduce its nitrogen fixation capacity.
Nitrate nitrogen fertilizer is not applied in paddy fields. Ammonium nitrate, sodium nitrate, etc. will dissociate nitrate ions, which can easily be leached into the deep soil in the paddy fields, resulting in denitrification and loss of nitrogen. The application of nitrate nitrogen in drylands is also forbidden before heavy rain, or watering after application.
Ammonium sulphate avoid long-term application, ammonium sulfate is a physiological acid fertilizer, long-term application in the same soil will increase its acidity, destroy the structure of the granules; in alkaline soil, ammonium sulfate is absorbed, and acid ions remain in the soil and Calcium reacts to harden the soil.
Ammonium bicarbonate should not be applied shallowly. It should be applied under 6 cm deep. Immediately after application, it should be covered with soil. It is also not suitable for use in the greenhouse. Because ammonium bicarbonate is commonly referred to as gas fertilizer, it is easily decomposed into ammonia in the greenhouse and volatilizes, causing waste; and when the ammonia concentration is too large, it also burns crop leaves.
Potash fertilizer should be applied at the end of the crop. Potassium can be transferred from the lower stem and leaves of the crop to the top part and reused. The symptoms of potassium deficiency are later than the symptoms of nitrogen deficiency and phosphorus deficiency. The potassium fertilizer is best applied as a base fertilizer, or applied at the seedling stage.
Contains chlorinated fertilizers such as potassium chloride, ammonium chloride, avoid application to saline soil and chlorine crops. Chloride ions contained in chlorinated fertilizers will remain in the soil, resulting in acidification of the soil, which will increase salt damage when applied in saline-alkali fields; application on chlorine-tolerant crops will affect yield and quality.
