Product description
Phosphoric Acid 85% Liquid Fertilizer High Phosphorus for Roots and Flowers
Phosphoric Acid 85% is a concentrated high-phosphorus liquid fertilizer, used as an effective source of phosphorus in fertilization programs, especially during root growth stages, early growth, pre-flowering, and improving the readiness of nutrients within the soil. The product helps support the formation of a strong root system, improve water and nutrient absorption when used as part of an appropriate irrigation fertilization program.
The product falls under soil salinity enhancers and soil property improve-ment products, and can also be used within liquid fertilizer programs for crops that need a liquid phosphorus source to help reduce irrigation solution alkalinity and improve nutrient uptake efficiency.
Features of Phosphoric Acid for Plants and Irrigation Networks
A concentrated liquid source of phosphorus helps support root and flowering growth.
Helps reduce irrigation solution alkalinity and alkaline soil when used correctly.
Supports the readiness of phosphorus and nutrients in the root zone.
Helps clean irrigation networks from some salts and deposits.
Suitable for drip and flood irrigation systems according to the agricultural program.
Supports absorption of macro and micronutrients when adjusting irrigation and fertilization.
Suitable for agricultural crops, vegetables, trees, palms, and greenhouses.

Uses of Phosphoric Acid 85% for Crops
Used during stages when the plant needs clear phosphorus support, especially during early growth, root activation, and before flowering. Also beneficial in high-alkalinity soils and irrigation water, as it helps improve nutrient absorption conditions in the root zone.
Suitable for vegetable crops during early growth and pre-flowering.
Supports fruit trees and palms within fertilization and irrigation programs.
Helps improve fertilization efficiency inside greenhouses and open fields.
Included in network cleaning and maintenance programs to remove deposits.
Suitable when a fast-availability liquid phosphorus source is needed.
Benefits of Phosphorus in Phosphoric Acid for Roots and Flowers
Phosphorus is an essential element in root formation and energy within the plant, so using a high-phosphorus source like phosphoric acid is suitable during establishment and pre-flowering stages. It also helps reduce irrigation solution alkalinity to improve the availability of some elements and reduce their fixation in alkaline soil.
For better benefit, the product can be integrated into a balanced fertilization program, with monitoring of soil and water conditions, and not relied upon as a complete substitute for other nutrients the plant needs.
Phosphoric Acid to Improve Soil Properties and Reduce Alkalinity
Phosphoric acid helps lower the alkalinity of irrigation water and soil solution, which improves the availability of some nutrients to the plant. It can also help reduce salt deposits inside irrigation networks, especially in systems affected by high alkalinity or limestone deposits.
In saline or alkaline soils, it is preferable to use it as part of a broader program that includes irrigation and drainage management, supported by suitable soil and media products or soil conditioners depending on soil condition and crop type.
Method of Using 85% Phosphoric Acid
With drip or flood irrigation: add 8-10 liters per feddan at the beginning of growth or before flowering, repeated as needed based on crop stage and requirements.
Foliar spraying: use 100-150 ml per 100 liters of water, repeated every 7-10 days depending on the plant stage and crop condition.
In irrigation networks: used cautiously within network maintenance programs to reduce deposits, ensuring compatibility with system components and other products.
Adhere to the instructions on the package or the agricultural specialist’s recommendation, and do not increase the dose arbitrarily. During preparation, add the acid slowly to water with stirring, and do not add water directly to the acid. Use appropriate protective equipment during preparation and application.
Important Precautions When Using Phosphoric Acid
A concentrated acidic product; handle carefully with gloves and protective glasses.
Do not mix arbitrarily with fertilizers or pesticides, especially calcium products or concentrated mixes.
Perform a simple compatibility test before mixing with other products.
Avoid contact with skin or eyes, and keep the container out of reach of children and animals.
Store in a suitable place away from direct sunlight and high heat.
When Do You Need Phosphoric Acid in Your Fertilization Program?
When a liquid phosphorus source is needed to support roots.
During early growth or pre-flowering depending on crop needs.
When irrigation water alkalinity is high or nutrient readiness is weak.
When there are deposits in irrigation networks requiring careful maintenance.
Within programs to improve nutrient absorption efficiency in alkaline soils.
Difference Between Phosphoric Acid and NPK Fertilizers
Phosphoric acid is a concentrated acidic phosphorus source, also used to help reduce alkalinity and improve irrigation network efficiency. NPK fertilizers provide balanced or targeted compositions of nitrogen, phosphorus, and potassium.
Therefore, phosphoric acid is used as part of a fertilization program, not as a complete substitute for all fertilizers.
Frequently Asked Questions About 85% Phosphoric Acid
What is the benefit of phosphoric acid for the plant?
It helps supply phosphorus, supports root and flowering growth, reduces irrigation solution alkalinity, and improves nutrient readiness.
Can phosphoric acid be used with drip irrigation?
Yes, it can be used with drip irrigation within an appropriate fertilization program, adhering to the dose and avoiding incompatible mixing with other products.
Does it help clean irrigation networks?
Yes, it can help reduce some deposits and salts inside irrigation networks, but should be used cautiously and in suitable doses depending on network condition and deposits.
Is phosphoric acid suitable for alkaline soil?
Yes, it can be suitable for alkaline soil or water because it helps lower the pH of the irrigation solution and improve nutrient availability.
Can it be mixed with calcium?
It is not recommended to mix it arbitrarily with calcium products or concentrated mixes, as this may cause deposits or undesired reactions. Conduct a compatibility test or consult an expert.
Does it replace other fertilizers?
No, it is an acidic phosphorus source and does not replace a comprehensive fertilization program that includes nitrogen, potassium, and trace elements according to plant needs.
