What effect does diammonium phosphate have on fruit trees?

Diammonium phosphate is a fertilizer that can be used on many crops, so what exactly is the effect of diammonium phosphate on fruit trees? Let's take a look!

1. Basic introduction to diammonium phosphate

Diammonium phosphate refers to a chemical substance whose standard product contains N18%, P2O548%, with a crystal shape of flat oblique prismatic crystals, a solubility of 71% in water at 25°C, and a saturated solution with a pH reaching 8.

Diammonium phosphate, also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer containing two nutrients, nitrogen and phosphorus. It appears as grayish-white or dark gray granules, with a specific gravity of 1.619, is easily soluble in water, and insoluble in ethanol. It has a certain hygroscopicity and easily decomposes in humid air, volatilizing ammonia and becoming monoammonium phosphate.

Diammonium phosphate is a high-concentration quick-acting fertilizer, suitable for various crops and soils, especially for crops that favor nitrogen and need phosphorus. It can be used as a base fertilizer or a top dressing, and is best applied deeply.

2. The effect of diammonium phosphate on fruit trees

Diammonium phosphate is a high-concentration quick-acting fertilizer. Applying diammonium phosphate to fruit trees can make the fruit they produce large and sweet, and can also increase fruit yield.

When applied, it mixes well with urea, ammonium nitrate, and ammonium chloride. Since it does not itself contain potassium, it should be applied together with potassium fertilizers (potassium chloride, potassium sulfate).

3. Precautions for use

1. Because diammonium phosphate can irritate the eyes, respiratory system, and skin when used, wear appropriate protective clothing;

2. If it accidentally comes into contact with the eyes, immediately rinse with plenty of clean water and seek a doctor's advice.
