ULTRASOL MICRO REXENE FeXQ48

Iron is considered a slow-moving element within the plant. Therefore, symptoms of its deficiency appear on young leaves, while the terminal bud remains alive. Yellowing appears on the young leaves, spreading between the veins that remain green. With continued deficiency, yellowing affects all parts of the leaf, which becomes pale white, and eventually burnt spots appear. The yellowing resulting from iron deficiency is called chlorosis. When symptoms of iron deficiency appear, it does not necessarily mean that it is not available in the soil. On the contrary, it has been found that most cases of iron deficiency occur in soils rich in this element, but it may be in a form that is not readily absorbable due to high soil pH or high levels of calcium carbonate (CaCO3). Therefore, deficiency symptoms usually appear in plants growing in the limestone and alkaline soils of Egypt.

The physiological functions of iron in plants are as follows:

  • Iron is involved in the formation of the enzyme cytochrome oxidase, which is associated with respiration in plant roots.
  • It is also involved in the formation of the enzyme peroxidase, which oxidizes phenolic compounds in the presence of hydrogen peroxide.
  • Although it is not directly involved in the chemical structure of chlorophyll, it is related to an enzyme that assists in chlorophyll synthesis.
  • Iron plays a crucial role in converting nitrogen dissolved in leaves into protein. This protein has a significant role in protecting chlorophyll from sunlight.

    Ultra Sol Micro Rexin FX 48 is a high-chelation iron compound with a high degree of purity. It contains the chelating agent EDDHA, which is considered one of the most stable and effective chelating agents in terrestrial and soilless agricultural application

    Features of Ultracool Micro Rexin Iron Chelate QX 48:

    • It guarantees stability of chelation over a wide pH range from 3.5 to 12, making it suitable for use under alkaline and calcareous soil conditions.
    • The compound is in the form of fine particles that dissolve completely in water, allowing it to be rapidly absorbed by plant roots, resulting in a quick response from the plants.
    • It is chelated with EDDHA, with an iron percentage at the Ortho-Ortho site around 4.8% and at the Ortho-Para site around 1.2%.
    • It can be used through modern irrigation systems such as drip irrigation, pivot irrigation, or sprinkler irrigation, or directly through the soil.
    • It is used in the early stages of plant growth to ensure continued effectiveness throughout the growing season, leading to maximized production.

The best way to add Ultrasol Micro Rexin Iron Q48 fertilizer to the soil is by dissolving it in an appropriate amount of water with stirring, then spraying it as a coarse mist or through irrigation systems. Alternatively, it can be added to an appropriate amount of water in a spraying tank with stirring and used at the following rates.
