The Roles of Molybdenum in Fertilizers and Agriculture

Explore the vital roles of Molybdenum in agriculture, its impact on plant growth, and the consequences of its deficiency and overdose in soil and plants.

Table of Contents

Molybdenum is a minor nutrient essential for plant growth as it balances the uptake of other micronutrients. It’s important for performing major functions such as nitrogen fixation, and the formation of important plant life molecules for plant parts development. However, it’s important to note the amount of molybdenum fertilizer in soil because its deficiency and overdose can affect the plants badly. 

In this article, I will highlight the roles of Molybdenum in agricultural growth and how it can impact the plant’s life. Moreover, I will mention the deficiency, overdose, and sources of Molybdenum for plants. This complete analysis helps to understand the Roles and importance of Molybdenum in plant life and development. 

Sources of Molybdenum for Plants

Soil is a great medium for providing the right content of Molybdenum to the plants. However, the acid soil doesn’t allow the plants to take up the essential amounts of Molybdenum from the soil. Neutral and alkaline soil makes the uptake easier for plants. 

Prominent Roles of Molybdenum in Agriculture

Prominent Roles of Molybdenum in Agriculture

Molybdenum performs some prominent roles within the life cycle of plants. These are essential for the formation and structural development of the plants. The explanation of the Roles of Molybdenum in plants and agriculture are as follows: 

  • Nitrogen Fixation

Nitrogen is available in the atmosphere but can’t be used by the plants directly. The plants utilize this nitrogen after converting it into usable plant elements. Molybdenum is helpful for nitrogen fixation in the plants from soil. This cycle is essential for the growth and development of the plants. 

  • Formation of Nitrogen Based Compounds in Plants

Nitrogen is converted and combined with other molecules to form essential plant growth elements. Molybdenum helps the plant body utilize nitrogen to form chlorophyll, proteins, and amino acids. These essential elements are important for the formation of the plant parts development and to carry on the functions of plant parts. 

  • Roles in Citrus Pants

Molybdenum acts as a plant skin that is thicker in the fruits. Besides this, it also ensures more juice within the juicy plants. They surely affect the Yield of citrus plants and improve growth gradually. 

  • Formation of Molybdoenzymes 

The presence of the Molybdenum in plants improves and produces the molybdoenzymes in the plant cells. These are helpful for plant regulations. They perform various functions within plant life. It’s helpful for the conversion of nitrates and transforming them into essential proteins.  

  • Improves Symbiotic Relationships 

Molybdenum helps establish healthy relationships between plants and microorganisms. These are helpful for the rhizobia bacteria and carry the functions of the element fixations within the plants. 

  • Enzymes 

In most plant enzymes, the Molybdenum is useful for providing the right quantities of nutrition to the plants. Most enzymes, such as nitrate reductase, sulfite oxidase, and many other plant enzymes, use Molybdenum. Thus, indirectly, it’s also involved in various other plant reactions. 

  • Processing of Genetic Material

Molybdenum is useful and carries out the processing of genetic material such as DNA. Its presence is important within the plant cell to develop the complete genetic system. Genetic material is useful for transferring genetic information.

  • Boost Plant Growth and Productivity

Molybdenum is found to be important in that it can promote and boost the growth of plants. The plants that grow with the right amounts of Molybdenum are observed as healthier, with fast growth and high productivity. Plants mainly utilize it to be useful for the leaf’s improvement of seed formation.

Most Useful Types of Molybdenum Fertilizers in Agriculture

Molybdenum Fertilizers in Agriculture

Naturally, small amounts of Molybdenum are present within the soil. However, sometimes, the concentration of the Molybdenum is not enough according to the plant and soil requirements. For this purpose, the following fertilizes are the most useful types of fertilizers in agriculture that are:

  • Ammonium Molybdate

These are slow-dissolving molecules within the water. However, foliar and drip methods are highly useful for application. These are helpful fertilizers for producing amino acids within the plant body. It’s important for the regulation of plants functioning as well.

  • Sodium Molybdate

These are used in the form of crystals, are conveniently used all kg with the water, and are utilized in the form of sprays. They release the Molybdenum instantly into the soil and make them available for plant development. It boosts the plants’ growth and improves the productivity rate.

  • Molybdenum Trioxide

It does not count as a soluble fertilizer, and that’s why you can’t use it in the form of sprays. These are helpful for plant growth because they contain the exact content of Molybdenum that the plants require. In hydroponic farming, this fertilizer is highly useful for growth.

Insights on the Impacts of Molybdenum in Soil

Soil has an essential amount of Molybdenum in it. This presence of elements supports the growth of plants and increases the rate of development. They improve the symbiotic relationships of the plants. They provide the microbes with a root surface to interact with the plant’s root hairs and structure. After that, the microbes start feeding on the plants. In return, these are helpful to maintain the concentration of the other important nutrients within the soil. It improves the plant’s productivity and the plant’s overall healthy Yield. Their presence improves and increases the soil fertility. Besides this, it also balances the soil’s pH level. 

Maximum Amount of Molybdenum  for Crop’s

However, according to the plant’s needs, a soil test is used to find the exact quantity of the Molybdenum in soil. The maximum limits for Molybdenum range from 0.5 to 2 lb/A. These are used in the form of fertilizers for plant growth. Besides this,  it is also used along with a combination of other fertilizers. 

Impacts Of Molybdenum Deficiency On Plants

Molybdenum must be used for the plant’s growth in the right quantity. However, if the concentration of Molybdenum is lower than the required amounts, it can be problematic for plant life and functions.

  • Due to the molybdenum deficiency, the plant’s leaves become pale, damaged, and deformed. 
  • It stops the settings of the fruit and thus affects the plants’ health.
  • The older leaves of the plants start to turn the scorched edges.
  • The plants cannot fix the usable amounts of nitrogen within the plant roots. 
  • Moreover, they also stunt the growth of the plant parts. 
  • The flower formation of the plants has ceased in the plants.

Impacts of Overdose of Molybdenum on Plants

Impacts of Overdose of Molybdenum on Plants

  • The overdose of Molybdenum caused toxicity in the plants and soil.
  • Its high concentrations turn the leaves and legumes yellow. 
  • Besides this, the continuous high amounts of Molybdenum also accumulate the chemical anthocyanin in the plant leaves, resulting in the purple appearance of leaves.

Conclusions

Molybdenum is an essential nutrient that is useful in lower quantities and performs major roles in the life of plants. These are counted as essential elements that work for nitrogen fixation and ensure the formation of other important nitrogen molecules that comprise the leaf structure and fruit content level. However, according to the complete Analysis, it’s observable that you must proceed with the right fertilizer in the right quantities; otherwise, it is damaging to the plant’s health and affects the overall plant yield.
