The Roles and Benefits of Chelated Fertilizers for Crop Yield

Discover the key roles and benefits of chelated fertilizers in agriculture, focusing on enhanced crop yield, efficient micronutrient uptake, and improved plant health.

Table of Contents

Chelated fertilizers keep the related micronutrients away from the undesirable reactions and toxicity within the plants. These fertilizers improve plant growth and are also known for their importance in improving the bioavailability of other essential plant micronutrients. 

In this article, I will elaborate on the details of chelate fertilizers and their benefits in improving crop yields. I will share the most useful and preferable chelated fertilizers with their prominent agricultural benefits. Besides this, it will also emphasize the impact of using these fertilizers in agricultural soils.

What are Chelated Fertilizers?

These are the fertilizers with the micronutrient ion in their structure and are surrounded by the larger molecule called a Chelator. These Chelator molecules are also called Ligands. As a result, the fertilizers made by using this molecule are called the chelated micronutrient.

Sources of Chelated Fertilizers for Plants

Sources of Chelated Fertilizers for Plants

The chelated fertilizers are introduced naturally into the plants and can be provided as chemical fertilizers. Some vitamins also have chelating properties. It removes the toxic impact within the plants. The chelating agent is mostly powered to the fine form, and this one is mixed with the desired sulfate micronutrients. These fertilizers are applied to the plants in different forms such as., foliar sprays, direct application, liquid, and soluble insertion. 

Prominent Benefits of Chelated Fertilizers for Crop Yield

Although the presence of the various micronutrients is essential to upgrade plant growth and crop yield. These chelated Fertilizers provide the right fertilizer content to the plants. Some of the most prominent roles of chelate Fertilizers for plants are as follows: 

  • Micronutrients Uptake

The introduction of chelated fertilizers helps increase plant uptake rates of micronutrients. These micronutrients are essential for the plant’s growth and development. They make nutrient absorption easier for the plants. The presence of other micronutrients for the plants is also important that’s why it makes the zinc, copper, iron, and other fertilizers available to the plants.

  • Quick Absorption 

Cheated fertilizers are known due to their absorption ability. These Fertilizers are immediately taken up by the soil and absorbed by the plant parts. Besides this, These fertilizers improve plant growth and productivity. 

  • Plant Productivity

Chelated fertilizers improve the plant productivity rate due to their important role in maintaining the availability of copper, zinc, manganese, and iron and their quick absorption in the plants. The plant’s relativity encourages the growth of plant parts that introduce the growth booster toward the plant’s yield and productivity. Many plants require these minerals and micronutrients for plant productivity. 

  • Reduces Plants Toxicity

These chelated compounds are useful for the plant’s growth. These are highly useful for reducing the level of plant toxicity. This toxicity can be a result of multiple reasons. Most plant nutrients are present in the soil in reactive forms that can harm the plants. Usually, copper and iron are found in reactive forms within the soil. This toxicity is overcome and can be reduced with the help of chelated fertilizers. 

  • Improves Plant Immunity

The presence of the chelate Fertilizers also induces immunity in the plant parts and their structure. This immunity helps resist most of the pests and diseases. They help modify the plant’s structure and make it healthier by protecting it from pathogens.

Types of Chelated Fertilizers with Their Benefits

Types of Chelated Fertilizers with Their Benefits

These chelated fertilizers involve the micronutrients in combination with the bonding of Organic molecules. These are important and easily taken up by the plant roots to perform various roles in the plant structure. Following are the most useful chelated fertilizers with their specific benefits: 

1. Chelated Copper (Cu) 

These fertilizers work impressively for plant growth. Copper-chelated fertilizers are plant growth promoters, enhancing the reproductive performance and plant cycle. It improves the working of the plant enzymes related to the important functions in the plant parts. 

2. Chelated Magnesium (Mg)

These fertilizers include magnesium in chelated form, important for performing various roles in plant growth. These chelated fertilizers support the introduction of nutrient absorption and encourage the plants’ photosynthesis rate. The presence of magnesium is important for the production of plant chlorophyll

3. Chelated Iron (Fe)

These chelated fertilizers are important for improving the plants’ photosynthesis rate. The plant fertilizer is important due to the presence of iron inside it. They promote the functioning of the plant organs as well.

4. Chelated Calcium (CA) 

The presence of calcium within the plants is important to perform various important functions. The chelated calcium benefits plant growth and carries on the nutrient uptake process within the plant roots. Moreover, it also introduces the production of chlorophyll within the plant leaves. 

5. Chelated Manganese (Mn) 

Manganese is also one of the important plant micronutrients. It’s helpful to prevent the micronutrient deficiency within the plants. Moreover, it’s an essential element that is involved in the formation of various Plant hormones. Besides this, it’s also an important element for continuing the process of plant photosynthesis. 

6. Chelated Zinc (Zn) 

The presence of zinc in the chelated Fertilizers is important to promote plant growth and the overall nutrient absorption of the plants inside the cells. Zinc improves the structure and is important for continuing various plant functions.  

Impact and Benefits of Chelated Fertilizers on Agricultural Soil

Impact and Benefits of Chelated Fertilizers on Agricultural Soil

Inserting the chelated fertilizer within the soil positively impacts the soil. It makes sure that the other plant micronutrients are available in the soil. These fertilizers are important for promoting healthy soil that improves the rate of growth and development of plants. The presence of these chelated fertilizers in the soil also protects the plants and keeps them away from pathogens. These fertilizers increase the soil fertility over time. 

Case Studies: Success with Chelated Fertilizers

Tomato Farm in California

A Californian farmer reported a 30% increase in tomato yield after switching to chelated iron and zinc fertilizers. The enhanced nutrient uptake led to healthier plants and larger fruits, significantly boosting market sales.

Soybean Production in Brazil

In Brazil, a soybean producer used chelated manganese to overcome manganese deficiency in highly alkaline soils. The result was a noticeable improvement in plant vigor and a 20% increase in overall yield compared to previous seasons.

Vineyard in France

A vineyard in Bordeaux used chelated copper to enhance disease resistance in grapevines. The vintner observed healthier vines and a reduction in fungal diseases, leading to higher quality grapes and better wine production efficiency.


Chelated fertilizers are the right utilization of micronutrients that rapidly promote plant growth and are highly useful in improving plant productivity. These fertilizers are present according to the various types of micronutrients. Using the right micronutrient in the right proportion will encourage the plant’s growth and introduce an energy booster within the plant’s structure. The chelate elements are also helpful in promoting plant uptake of other micronutrients.
