Urea Phosphate 18-44

General Properties and Industrial Significance:

Urea Phosphate 18-44 is a water-soluble fertilizer that contains 18% Nitrogen (N) and 44% Phosphorus (P₂O₅). It is primarily used to supply nitrogen and phosphorus to plants, which are essential nutrients for their growth and development. Urea phosphate combines the benefits of urea, a nitrogen source, with phosphoric acid, providing plants with two key nutrients that play a role in a variety of vital processes.

Urea Phosphate (UP) is created by reacting urea (NH₂CONH₂) with phosphoric acid (H₃PO₄). The resulting compound is highly soluble in water, making it easy for plants to absorb the nutrients directly through their roots.

Urea Phosphate 18-44 contains:

  • 18% Nitrogen (N): Nitrogen promotes leaf and stem growth, supports photosynthesis, and is involved in other metabolic processes in plants.

  • 44% Phosphorus (P₂O₅): Phosphorus plays a critical role in root development, flowering, fruiting, and energy transfer within the plant. It is especially important for the early stages of plant growth.

 

Applications:

  • Fertilizer for Agricultural Crops:

  1. Soil Application: Urea Phosphate 18-44 is commonly used in agriculture to supply essential nutrients to crops. The 18% nitrogen helps with vegetative growth, while the 44% phosphorus promotes root development and supports flowering and fruiting.
  2. Root and Early Growth: The high phosphorus content in Urea Phosphate makes it particularly beneficial for promoting root development. This helps plants establish strong, healthy root systems that are critical for nutrient and water uptake.
  • Hydroponic Systems:

  1. Hydroponic Fertilizer: Urea Phosphate 18-44 is used in hydroponic systems, where it provides plants with an easily accessible form of nitrogen and phosphorus. In hydroponics, nutrients are delivered directly to the plant's roots through the nutrient solution, and Urea Phosphate ensures that plants receive these critical nutrients.
  • Starter Fertilizer:

  1. Starter Fertilizer: Urea Phosphate 18-44 is used as a starter fertilizer, particularly for crops that need strong root systems to thrive. The phosphorus in Urea Phosphate helps with early root growth, making it an excellent choice for promoting seedling establishment and ensuring a strong start for new plants.
  • Improvement of Soil Fertility:

  1. Soil Fertility: Urea Phosphate is often applied to soils to improve phosphorus availability, especially in soils that are low in phosphorus. Phosphorus is essential for plants to form strong roots, produce flowers, and set fruit, so this fertilizer is crucial for improving overall soil fertility and supporting plant productivity.
  • Foliar Fertilizer:

  1. Foliar Application: Urea Phosphate 18-44 can also be used as a foliar fertilizer, where it is sprayed directly on plant leaves. This method allows plants to absorb nutrients quickly through their leaves, especially during times of nutrient deficiency or stress.
 

Key Benefits:

  • High Phosphorus Content:

The 44% phosphorus in Urea Phosphate makes it an excellent choice for promoting root growth, early-stage plant development, and supporting flowering and fruiting.
  • Water Solubility: 

Urea Phosphate 18-44 is highly soluble in water, which allows for easy nutrient uptake by plants through both soil and hydroponic systems.
  • Boosts Early Growth:

The combination of nitrogen and phosphorus supports both vegetative growth and root development, making it ideal for starter applications in a variety of crops.
  • Improves Fertility:

This fertilizer is useful in correcting phosphorus deficiencies in the soil, enhancing soil fertility and ensuring that plants have access to essential nutrients.
  • Suitable for Various Crops:

Urea Phosphate 18-44 can be used on a wide range of crops, including row crops, fruits, vegetables, and ornamentals.
 

Common Applications:

  • Row Crops:

Urea Phosphate 18-44 is applied to corn, wheat, soybeans, rice, and other row crops to support early growth and root development.
  • Fruit and Vegetable Crops:

It is also used in horticulture for fruit trees, vegetables, and flowers, where the phosphorus aids in flowering and fruit production.
  • Home Gardens:

Home gardeners use Urea Phosphate 18-44 to encourage healthy growth and improve the root systems of their plants.
 

Summary:

Urea Phosphate 18-44 is a water-soluble fertilizer containing 18% nitrogen and 44% phosphorus, making it an excellent choice for supporting root development, vegetative growth, and overall plant health. It is used in agriculture, hydroponics, and gardens to improve soil fertility, promote early growth, and boost root establishment. Its high phosphorus content also makes it ideal for flowering and fruiting plants.
