The benefits of Haifa Micro™ - micronutrients fertilizer
- All micronutrients are in a chelated form, to maximize stability and efficiency
- Haifa Micro™ chelates are absorbed by the plant rapidly and efficiently
- Haifa Micro™ chelates are fully soluble in water
- Compatibility with a wide range of agrochemicals enables tank-mixing, thus reducing the cost of spray operations by minimizing the number of application needed
The mechanism of chelates
Chelate is a complex of a micronutrient ion and an organic molecule that "holds" it, called ligand. As long as the ion is attached to the ligand, it is protected from interacting with other ions in the solution, which might turn it unavailable for plant uptake.
As the micronutrient ions are consumed by the plant, more ions are released from the holding ligands, thus becoming available for plant uptake.
This mechanism maximizes the efficiency of the micro nutrients applied. When Haifa Micro™ is applied by Nutrigation™, the chelates ensure availability of micronutrients in both alkaline and acidic soils.
Iron (Fe) plays an important role in chlorophyll formation. It is involved in cell division that supports plant growth, and in other vital reactions in the plant.
Typical deficiency symptoms: leaf yellowing, interveinal chlorosis.
Iron deficiencies in corn 
Iron deficiencies in soybean
Iron deficiencies in canola
The solution: Haifa Micro™ Fe
Manganese (Mn) is required for photosynthesis and respiration. It improves green color and increases sugar and protein content. Manganese enhances plant tolerance to high light intensity.
Typical deficiency symptoms: chlorotic mosaic patterns on leaves.
Manganese deficiencies in avocado 
Manganese deficiencies in corn
Manganese deficiencies in soybean 
Manganese deficiencies in tomato
The solution: Haifa Micro™ Mn
Zinc (Zn) is involved in synthesis of proteins and in the formation of seeds and promotes plant growth and vigor.
Typical deficiency symptoms: blotching of leaves.
Zinc deficiencies in sugarcane 
Zinc deficiencies in corn
Zinc deficiencies in pecan 
Zinc deficiencies in citrus
The solution: Haifa Micro™ Zn
Copper (Cu) is essential for chlorophyll formation, cell wall building and many enzymatic mechanisms. It supports seed formation and reproduction, increases sugar content, intensifies color and improves flavor in fruits and vegetables.
Typical deficiency symptoms: wilting of top leaves.
Copper deficiencies in wheat 
Copper deficiencies in corn
The solution: Haifa Micro™ Cu
