What is the reason why plant ash and ammonium nitrogen fertilizer cannot be mixed?

Reasons why plant ash and ammonium nitrogen fertilizer cannot be mixed:After the mixing of plant ash and ammonium nitrogen fertilizer, the double hydrolysis reaction will occur, and the ammonia gas will easily escape, resulting in the equilibrium shifting to the right, and the concentration of ammonium ions in the soil will decrease, and then the fertilizer efficiency will decrease.

Grass ash should not be mixed with superphosphate, otherwise it will reduce the effectiveness of phosphorus. Grass ash is easy to dissolve in water, and the potassium in it will decrease when it encounters water, so waterproof measures should be taken during storage.

The main components of ammonium nitrogen fertilizer are ammonia, liquid ammonia, ammonium salt (such as ammonium chloride, ammonium sulfate, ammonium bicarbonate, etc.), so ammonium nitrogen fertilizer can not be mixed with alkaline substances, otherwise ammonia will escape.

Grass and wood ashAfter mixing with ammonium nitrogen fertilizer, it is producedAmmoniaIt will volatilize, resulting in the loss of nitrogen, so ammonium nitrogen fertilizer cannot be mixed with plant ash. Grass ash is easily soluble in water and meets waterPotassiumIt will be reduced, it should be waterproof and preserved, and the plant ash should not be mixed with superphosphate and mixed, otherwise the effectiveness of phosphorus will be reduced.

Ammonium nitrogen fertilizer is mainly liquid ammonia and ammonia.

and ammonium salts produced by ammonia and acid, such as ammonium sulfate.

Ammonium chloride, ammonium bicarbonate.

Wait. Ammonium nitrogen fertilizer cannot be applied together with alkaline substances and stored to prevent ammonia from escaping and reduce fertilizer efficiency. Grass ash is alkaline after hydrolysis, so plant ash cannot be applied with ammonium nitrogen fertilizer and superphosphate, nor can it be applied with human manure and decayed organic fertilizer.

Precautions for plant ash

Plant ash contains a large number of mineral elements, and many of its nutrients are easily soluble in water. If it is in a humid environment, it is easy to cause the loss of nutrients. Once wet by heavy rain, the loss of potassium is particularly severe.

Therefore, under normal circumstances, if you want to store plant ash fertilizer, you must choose a dry and sheltered place from rain and wind, and try to build an ash shed, so as to ensure that the plant ash is not eroded by rain and retain its nutrients for later use. If possible, try to seal and store the plant ash in a plastic bag, so that the storage time is longer, and it will not cause environmental pollution and waste.

The reason why ammonium nitrogen fertilizer cannot be mixed with plant ash is that ammonia can be released after mixing, which reduces fertilizer efficiency.

Ammonium nitrogen fertilizer contains ammonium ions, and potassium carbonate, the main component of plant ash, is hydrolyzed to form hydroxide ions, which can react

The resulting ammonia gas escapes into the air, reducing fertilizer efficiency.

All nitrogen fertilizers containing ammonium root are called ammonium nitrogen fertilizers, and they cannot be mixed with alkaline substances such as hydrated lime or plant ash when used.

In agricultural production, plant ash cannot be mixed with ammonium nitrogen fertilizer.

After hydrolysis in the soil, the plant ash is silent and contains OH ions, while the NH4 in the ammonium nitrogen fertilizer and the OH root in the plant ash react chemically to generate NH3 and gas, and lose the fertilizer effect.

Added: (NH4)2SO4+2NAoh=NA2SO4+2H2O+2NH3

Grass ash is alkaline, contains potassium salt, and is easy to undergo biochemical (double hydrolysis) reaction when mixed with ammonia nitrogen fertilizer, resulting in the loss of nitrogen, so ammonium nitrogen cannot be mixed with plant ash. Grass ash is easily soluble in water, potassium element will be reduced in water, should be preserved in rain, plant ash should be careful not to mix with superphosphate, mixed use, otherwise the efficacy will decline.

The ash matter of plants and trees is light and alkaline, easy to go with the wind when dry, easy to go with water when wet, and easy to cause nitrogen volatilization failure in contact with ammonium nitrogen fertilizer, so ammonium nitrogen fertilizer can not be mixed with plant ash.

Reasons why it cannot be mixed.

Grass ash contains potassium carbonate, potassium carbonate is a strong alkali and weak salt, the hydrolysis is alkaline, the ammonium ion hydrolysis solution is acidic, and the two will be mixed to produce a double hydrolysis reaction, 2NH4++CO32-2NH3 +CO2 +H2O, NH3 H2ONH3+H2O.

Ammonia gas easily escapes, causing the equilibrium to shift to the right, and the concentration of ammonium ions in the soil decreases, thereby reducing the fertilizer efficiency, so ammonium nitrogen fertilizer cannot be combined with alkaline fertilizer.

Characteristics of ammonia nitrogen fertilizer.

1. Soluble in water

Ammonium nitrogen fertilizers are easily soluble in water, and can produce ammonium ions and corresponding anions, which can be directly absorbed and utilized by crops.

2. It can be adsorbed by soil particles

The ammonium ions in ammonium nitrogen fertilizer can be adsorbed on the soil colloids after being exchanged with the existing cations on the soil colloids.

3. It is easy to decompose under the condition of alkaline segment

Ammonium nitrogen fertilizer will decompose when exposed to alkaline substances, and release ammonia gas after decomposition and volatilization loss.

The ash matter of plants and trees is light and alkaline, easy to go away with the wind when dry, easy to go with water when wet, and contact with ammonium nitrogen fertilizer is easy to cause nitrogen volatilization failure, so ammonium nitrogen fertilizer can not be mixed with plant ash. In addition, plant ash should be strictly avoided mixed with other farm manure.

Because of the escape of ammonia, it will cause nitrogen loss, grass and wood gray matter is light and alkaline, easy to go with the wind when dry, easy to go with water when wet, and easy to cause nitrogen volatilization loss when in contact with nitrogen fertilizer. Therefore, ammonium nitrogen fertilizer cannot be mixed with plant ash.

Ammonium nitrogen fertilizer mainly refers to liquid ammonia, ammonia water, and ammonium salts generated by the reaction of ammonia and acid, such as ammonium sulfate, ammonium chloride, ammonium bicarbonate, etc. Ammonium nitrogen fertilizer can not be applied together with alkaline substances, and stored to prevent ammonia from escaping and reduce fertilizer efficiency.

Grass ash is alkaline after hydrolysis, so plant ash cannot be applied with ammonium nitrogen fertilizer and superphosphate with empty hands, nor can it be applied with human manure and decaying organic fertilizer.
