In agriculture, every ounce of efficiency matters, and the role of micronutrients cannot be overstated. These essential elements, required by plants in small quantities, play a crucial role in their growth, development, and overall health. However, the efficiency of these micronutrients can often be compromised by factors such as soil conditions and nutrient availability. 

That’s where chelated micronutrients step in, offering a powerful solution to address nutrient deficiencies and maximize crop productivity. Here, we will explore the significance of chelated micronutrients in agriculture, their unique attributes, and how they can revolutionize how we approach crop nutrition.

What are Chelated Micronutrients?

Chelates are chemical compounds that contain a central metal ion bound to one or several organic molecules, or Ligands. Ligands form a ring structure around the metal ion in a way that resembles a claw surrounding an object, hence the name “chelate,” which comes from the Greek word for “claw.”

The chelate ring structure provides a heightened level of stability to the complex, making it more resistant to chemical reactions capable of breaking down or precipitating the metal ion.

Chelated micronutrients are essential minerals that are chemically bound to organic molecules, such as amino acids, organic acids, or peptides, to create a complex that plants can easily absorb.

What Are the Benefits of Using Chelated Micronutrients?

Chelation helps prevent micronutrients from being bound to other minerals in the soil, making them easier for plants to absorb. The chelation process forms a stable complex that is capable of resisting chemical reactions and staying intact as it passes through the root system.

  • Improved absorption: Chelation protects micronutrients from binding with other minerals in the soil, making them easier for plants to absorb. Plants can easily absorb the chelate complex, making nutrient uptake more efficient.
  • Increased stability: Chelated micronutrients are more stable and less likely to react with other environmental compounds, such as soil minerals. This allows micronutrients to release slowly over time.
  • Reduced toxicity: Chelation can also reduce the toxicity of certain minerals, such as iron or copper, by making them less reactive.
  • Enhanced plant growth: Chelated micronutrients are commonly used in agriculture to improve plant growth and crop yields. By providing essential minerals in a more bioavailable form, chelated micronutrients can help plants grow stronger, healthier, and more resistant to pests and diseases.

Overall, chelated micronutrients are important for improving nutrient uptake, stability, and effectiveness in a variety of applications.

What Are Common Chelated Micronutrients?

Chelated micronutrients are essential nutrients bound to organic molecules to enhance their absorption and utilization by plants, animals, and humans. Some common chelated micronutrients include:

  1. Iron (Fe) – chelated iron is commonly used in plant fertilizers to enhance photosynthesis.
  2. Zinc (Zn) – chelated zinc is often used in plant fertilizers to improve nutrient absorption and growth.
  3. Copper (Cu) – chelated copper is commonly used in fertilizers to enhance growth, enzyme function, and reproductive performance. 
  4. Manganese (Mn) – chelated manganese is often used in fertilizers to prevent nutrient deficiencies and promote growth. It’s also vital for photosynthesis and the production of plant hormones.
  5. Magnesium (Mg) – chelated magnesium is used in fertilizers to improve nutrient absorption and support chlorophyll production and photosynthesis.
  6. Calcium (Ca) – chelated calcium is commonly used in fertilizers to improve nutrient uptake while supporting cell wall structure and plant growth.

What Crops Can You Use Chelated Micronutrients On?

Chelated micronutrients offer valuable solutions for preventing and correcting micronutrient deficiencies in plants. They are particularly beneficial for crops growing in alkaline or high-pH soils, where micronutrients are often unavailable due to the formation of insoluble compounds. 

The chelation process protects micronutrients from precipitation and degradation. Because of that, various types of crops can benefit from the application of chelated micronutrient fertilizers. This includes crops such as fruits, soybeans, oilseeds, cereal crops, ornamentals, hydroponic crops, and tree nut crops. 

With chelated micronutrients, these crops can access necessary nutrients more effectively, promoting healthier growth, development, and improved yields. The unique suitability of chelated micronutrients lies in their ability to address micronutrient deficiencies in alkaline or high-pH soils, ultimately ensuring optimal plant nutrition across a wide range of crops.

How Do You Know Which Chelated Fertilizer to Use on Your Crops?

Choosing the right chelated fertilizer for your crops depends on several factors. Most importantly, you need to know the specific micronutrients your crops need, the soil conditions in your field, and the growth stage of your crops. 

Here are some general guidelines to help you choose the right chelated fertilizer:

Soil testing

Before choosing a chelated fertilizer, test your soil to determine which nutrients it may be deficient in. Knowing what micronutrients your soil lacks can help you find a fertilizer that contains the specific micronutrients your crops need, such as iron, zinc, manganese, or copper.

Crop Needs

Different crops have different micronutrient requirements, meaning it is crucial to choose an appropriate fertilizer for your specific crop. For example, some crops may require more iron than others or be more sensitive to copper toxicity.

Growth Stage

The micronutrient needs of your crops may vary depending on their growth stage. For example, crops may require more iron during rapid growth periods or flowering. Be sure to choose a fertilizer that can provide micronutrients in a form that is readily available during these stages.

Chelate Type

Chelated fertilizers can have different chelating agents, such as Amino Acids, Organic Acids, EDDHAor EDTA. The type of chelate used can affect the stability and availability of the micronutrient, so it’s important to choose a fertilizer that uses an appropriate chelate for your soil conditions and your crops.

Application Method

You can apply chelated fertilizers using different methods, such as foliar sprays, soil applications, or fertigation. Different application methods affect the efficacy of the fertilizer and the availability of the micronutrients to your crops.

Where Can You Purchase Chelated Micronutrients?

You can purchase chelated micronutrients from various sources, including agricultural suppliers, garden centers, and online retailers. Here are some places where you can acquire chelated micronutrients:

Agricultural Suppliers

Many agricultural suppliers carry chelated micronutrient fertilizers specifically for use in agriculture. These suppliers may include local farm supply stores, seed and feed stores, or larger agricultural supply companies.

Garden Centers

Some garden centers or nurseries may carry chelated micronutrient fertilizers for home gardens or small-scale farming operations. These fertilizers are typically available in smaller quantities or packaged for home use.

Online Retailers

Several online retailers specialize in agricultural and gardening supplies, including chelated micronutrient fertilizers. These retailers may offer a more extensive selection of products and can ship directly to your location.

Fertilizer Manufacturers

Many fertilizer manufacturers produce chelated micronutrients as part of their product line. These manufacturers may sell their products directly to farmers or through agricultural retailers.

When purchasing chelated micronutrients, it’s vital to choose a product appropriate for your specific crop and soil conditions and a reputable brand that has been tested and proven effective. Always read the product label and follow application instructions carefully to ensure the best results.

Final Thoughts on Chelated Micronutrients

Chelated micronutrients provide a powerful tool for preventing and correcting micronutrient deficiencies in various crops. Their unique ability to enhance nutrient availability in alkaline or high-pH soils makes them indispensable for optimal plant nutrition. 

Whether you are cultivating fruits, vegetables, grains, oilseeds, forage crops, ornamentals, hydroponic crops, or field crops, incorporating chelated micronutrients into your fertilization strategy can lead to healthier plants, improved yields, and overall agricultural success.
