IRON EDDHSA

Seyfer 320 is a fertilizer based on iron chelate, specifically designed to prevent and treat iron deficiency in crops, especially in the most sensitive ones, such as Citrus fruits. It is a high-quality and highly soluble product; it prevents and treats iron deficiency and its manifestations of "iron chlorosis", which is the interveinal yellowing that often occurs in leaves, causing reduced growth and, consequently, poor flowering and fruiting.

Iron chlorosis is often found in Citrus fruits (especially Lemon), Grapevine, Apple tree, Peach tree, Tomato, and Strawberry.

What is Iron Chelate used for?

Iron Chelate is a very important molecule that contains readily assimilable iron through the roots. Thanks to the high percentage of iron in the EDDHSA fraction, Iron Chelate provides the plant with iron quickly and for a prolonged period of time.

Iron is involved in various important physiological processes of the plant, such as photosynthesis, cellular respiration, and root absorption of important nutrients such as nitrate and sulfate.

Seyfer 320 is ideal for preventing and treating iron deficiencies.

Why use Iron Chelate?

Iron is a molecule that is naturally present in the soil, but its availability and assimilation depend heavily on the soil pH.

In alkaline or sub-alkaline soil, iron is present but will be blocked by the soil, thus being unavailable to plants.

To make iron available in high pH soil, it is necessary to acidify it, but often this procedure is difficult to implement and costly, and it can only be done in the long term.

In these soils, where plants often show symptoms of iron deficiency, it is necessary to intervene with Iron Chelates. In this formulation, iron remains available in the soil for a long time without becoming insoluble or unavailable.

Seyfer 320 at the recommended doses:

• Induces the synthesis of more consistent tissues;
• Advances flowering and harvest time;
• Allows for a better balance between vegetative and reproductive phases;
• Increases the size, color, and uniformity of fruits;
• Increases plant productivity;
• Improves the quality characteristics of the produce (sugar content, color, consistency, shelf life);
• Prevents and treats magnesium deficiencies by increasing chlorophyll production;
• Increases resistance to climatic adversities and water and heat stress;
• Increases resistance to pest attacks;
• Improves cell permeability, enhancing the ability to absorb nutrients;
• Facilitates crop recovery when pests or adverse conditions (frost, drought, herbicide treatments, etc.) hinder normal plant functionality.

All of this results in:

• More balanced plant growth with higher quality and quantity of produce;
• Increased fruit resistance;
• Better post-harvest preservation and increased transport resistance;
• Enhanced color, weight, and organoleptic characteristics of fruits.

The ideal Iron Chelate for Citrus fruits

Seyfer 320 can be used on all crops (stone fruits, pome fruits, citrus fruits, grapevines, vegetables, and ornamentals) through the roots.

What is the dosage of Iron Chelate?

The dosage of Iron Chelate depends on the type of crop and the degree of iron chlorosis.

• Grapevine: 25-50 gr per vine;
• Pome fruits and stone fruits: 25-50 gr per plant, depending on age and size;
• Citrus fruits and Olive trees: 40-50 gr for young plants, 50-80 gr for adult plants;
• Vegetable crops: 3-6 kg/ha after transplanting;
• Floriculture and ornamentals: 10-30 gr per plant.

How often should Iron Chelate be used?

Iron deficiency is a significant physiological disorder that can strongly affect the vegetative and, consequently, productive cycle of crops.

It is always recommended to carry out preventive treatments or, at most, at the appearance of the first symptoms of iron deficiency-induced yellowing, to ensure the best treatment results and avoid production losses due to chlorosis.
