58% Monoammonium Phosphate High Quality And Low Price

• Product Overview

58% monoammonium phosphate is a high-concentration and highly water-soluble nitrogen-phosphorus compound fertilizer. Among them, "58%" usually refers to its available phosphorus (calculated as P₂O₅) content being approximately 51-53%, and the total nitrogen (N) content being approximately 10-12%. The sum of the two is above 58%, meeting the national first-class product standard (total nutrients ≥58%). Its powdered form endows it with the characteristics of rapid dissolution and easy blending.

• Main technical indicators

· Appearance: White or grayish-white crystalline powder.

·Total nutrients (N+P₂O₅) : ≥ 58%

·Available phosphorus (P₂O₅) : ≥ 51-53%

·Nitrogen (N) : ≥ 10-12%

· Water-soluble phosphorus: It accounts for an extremely high percentage of available phosphorus (usually ≥90%) and has good water solubility.

·pH value (1% solution) : approximately 4.4-4.6, weakly acidic.

·Solubility: Readily soluble in water, approximately 40 grams can be dissolved in 100 grams of water at 20℃.

• Main features and advantages

· High nutrient concentration and excellent ratio: High phosphorus content is a key element for the early root development and flowering and fruiting of crops. Combined with an appropriate amount of nitrogen, it can meet the basic needs of crops in the early and middle growth stages, especially suitable for phosphorus-loving crops or phosphorus-deficient soils.

· Excellent water solubility: Its powder form dissolves much faster than its granular form, making it an ideal basic raw material for preparing clear liquid water-soluble fertilizers, drip irrigation fertilizers, and foliar fertilizers. It leaves no residue and is not prone to clogging the irrigation system.

· High absorption and utilization rate: Phosphorus exists in the form of orthophosphate and can be directly and rapidly absorbed by crops, with a higher utilization rate than ordinary phosphorus fertilizers (such as superphosphate).

· Stable physical properties: It is not prone to moisture absorption and caking (compared with diammonium phosphate), and is convenient for storage and mechanical application.

· Flexible formula: As a basic fertilizer, it can be conveniently mixed with potassium nitrate, potassium sulfate, medium and trace elements, etc., to customize special fertilizers with different formulas.

· Safety and environmental protection: It does not contain harmful components such as chloride ions and sodium ions, and is relatively safe for soil and crops.

• Main Uses

·As A raw material for high-end water-soluble fertilizers: It is the core raw material for the production of water-soluble fertilizers with macronutrients (the phosphorus source in A/B fertilizers).

·Drip irrigation and sprinkler irrigation fertilization: Directly dissolved in the irrigation system, it is used for precise fertilization of high-value crops in greenhouses, orchards, fields, etc.

· Foliar spraying: After dilution, it can be used as a fast-acting phosphorus source for foliar supplementation, especially during the flowering period and fruit expansion period of crops.

· Raw materials for compound fertilizer production: Used for manufacturing high-phosphorus compound fertilizers or blended fertilizers (BB fertilizers).

· Base fertilizer or top dressing: It can be directly applied to the soil as base fertilizer or early top dressing, but the powder form is more suitable for mechanical or manual broadcasting followed by soil covering/watering.

• Applicable crops

It is widely applicable to almost all crops, especially showing remarkable effects on those with high phosphorus demand or sensitivity to chlorine.

· Cash crops: Tobacco (the main source of phosphorus for high-quality tobacco-specific fertilizers), sugarcane, tea, cotton, rapeseed. 

· Fruits: citrus fruits, apples, grapes, strawberries, melons, etc. 

· Vegetables: tomatoes, cucumbers, peppers, potatoes, etc. 

· Food crops: Root promotion during the seedling stage of rice, corn and wheat.

• Precautions

· Acidic fertilizer: Its aqueous solution is acidic. Long-term use alone may aggravate soil acidification and is suitable for neutral or alkaline soil. When used for a long time in acidic soil, it is necessary to pay attention to adjusting it in combination with lime or alkaline fertilizers.

· Balanced nutrition: Its nitrogen-phosphorus ratio (N:P₂O₅) is approximately 1:5, with an extremely high phosphorus ratio. When in use, it should be based on the actual needs of the crops and the soil conditions. It is necessary to combine it with an appropriate amount of nitrogen fertilizer, potassium fertilizer and trace elements to achieve nutrient balance.

In summary, 58% monoammonium phosphate powder fertilizer is an efficient and high-quality water-soluble phosphorus source and an indispensable basic fertilizer in modern precision agriculture and water and fertilizer integration technology. When used correctly, it can significantly promote the growth of crop roots, flower bud differentiation and the improvement of fruit quality.
