The Role of Hydrogen in Agriculture or Fertilizer

Explore the crucial role of hydrogen in agriculture, its impact on plant growth, soil health, and the consequences of hydrogen deficiency.

Table of Contents

Plants require hydrogen as an essential nutrient for their growth. Hydrogen is the main element in most of the fertilizers. Naturally, it is available in the soil and air. It can also be provided to the plants using fertilizers. The deficiency of Hydrogen leads to stunted growth in plants. Moreover, it disturbs the normal functioning of the plant parts. That’s why hydrogen is a must element for the proper functioning of respiration, photosynthesis, and plant developmental stages. 

In this article, I am sharing the Importance and roles of hydrogen in agriculture. Moreover, it also includes the effects of Hydrogen deficiency in plants. 

Role of Hydrogen in Fertilizers

Role of Hydrogen in Fertilizers

First of all, Hydrogen is important to produce ammonia that is useful as fertilizer. Hydrogen is used for the extraction of ammonia. These are mainly the building blocks for the production of ammonia and some other fertilizers. Furthermore, it is also useful for the production of electricity as well as for producing fertilizers. 

Hydrogen Fertilizers

Hydrogen is the main component in the ammonia fertilizers. Besides this, Diammonium hydrogen phosphate is also a widely useful fertilizer in the market. 

Sources of Hydrogen for Plants

The major sources of Hydrogen for the plants are water and fertilizers. The content of hydrogen is also used to make the plant grow, promoting fertilizers. When the hydrogen splits from the water, it provides protection and nutrition to the plants. 

Important Roles of Hydrogen in Agriculture

Hydrogen performs a lot of functions and roles in the field of agriculture. Its presence promotes the functioning of the plant and its parts. The following are the top roles of Hydrogen in agriculture:

  • Improves Soil Fertility

Hydrogen changes the structure of the soil and thus improves the productivity of the soil with time. The right amount of soil nutrients is essential for the crop’s yield.

  • Growth of Microbial Communities 

The presence of hydrogen in the soil promotes the growth of microbial communities. These communities improve the rate of plant growth. Using these microbial communities, the plant can make associations that are healthy for the plants. Hydrogen provides the balance to the environment of microbes. 

  • Treatment of Root Rot

Mainly, the Hydrogen in agriculture is used for treating the root rot in the form of hydrogen peroxide. Afterward, it is also helpful for root oxygen recovery. Afterwards, using this the roots start to grow and improve with time. For the restoration of the oxygen within the plants, Hydrogen is the main component to do that. They kill the harmful bacteria and fungi within the plant root rot. 

  • Post-Harvest Activities

Hydrogen also plays an important role in post-harvest activities. Hydrogen is used in the form of gas for drying and cooling the grains. Besides this, it also plays an important role for heat purposes. 

  • Plant Respiration

In plant respiration, these are also helpful and ensure the healthy growth of the plant parts as well. The process of plant respiration is important to manufacture the right amount of plant food energy. 

  • Photosynthesis

Hydrogen is the main component that starts up the process of photosynthesis. Through the driving of protons within the electron transport chain it carries the process of photosynthesis. 

  • Stomatal Closure

Their presence balances and regulates the closing of the stomata as well. If the stomatal pores stay open throughout the day, they lose the water concentration within the plants. This may lead to water loss in the plants and affect overall growth. 

  • Stress Resistance 

The hydrogen element is helpful for plants to deal with stress resistance. They increase the plant’s defensive mechanism through the antioxidants. It makes the plant able to deal with the effects and presence of pests and diseases. 

  • Regulation of Flowering Time

Hydrogen ensures the regulation of the flowering and flowering period within the plants. The flowers with the presence of Hydrogen are often more regulated and develop healthy flowers on the plants. Besides this, it also improves the overall production and the growth of the flowers as well. 

  • Maintenance of Soil PH

Maintenance of Soil PH-Hydrogen in Agriculture or Fertilizer

The PH level of the soil affects the nutrient availability and uptake properties of plants. That’s why the right balance of the PH is important for the plants. The Hydrogen ions carry a neutral charge that is helpful for the maintenance of the soil elements. The hydrogen ions can work in both positive and negative modes according to the soil’s needs. 

  • Seedling Growth and Germination

Hydrogen element positively impacts seed germination and promotes the growth of the plant roots. These are involved in the synthesis of the anthocyanin as well. Right after the germination of the seeds, the Hydrogen elements also provide support to the newly growing roots. It directly promotes the health of the adventitious roots and root elongation. 

  • Promotes the Shoot and Plant Part Growth

The presence of Hydrogen affects plant growth positively by providing all the essential growth-promoting nutrient uptake to the plants. They work as growth enhancers for the plant shoot and leaves. It protects the plant parts from droughts. The plants can grow smoothly with the use of hydrogen. 

Effects of Hydrogen Deficiency on Plants 

In case of deficiency of the Hydrogen, the plant will face various types of effects on the plants that are as follows:

  • Due to the hydrogen deficiency, the plant leaves start to turn yellow with time. 
  • The premature leaves with the brown margin start to drop immediately in hydrogen-deficient plants.
  • The plants will face heavy drought conditions.
  • The continuous loss and unavailability of hydrogen in plants leads to wilting and even can cause plant death. 
  • These plants show stunts or slow plant growth. 
  • The plant’s ability for disease resistance reduces with time. 


What is the effect of hydrogen on plant growth?

Hydrogen is vital for plant growth, promoting essential processes like photosynthesis and respiration. It aids in ATP production, crucial for energy transfer within plants, resulting in healthier growth, robust root systems, and enhanced overall plant development.

How is hydrogen used in food production?

In food production, hydrogen primarily contributes to ammonia synthesis, a key component of fertilizers. These fertilizers enhance nutrient availability in soil, promoting healthier crop growth and thus, increasing food production efficiency and yield.

How does hydrogen help soil?

hydrogen help soil

Hydrogen plays a pivotal role in maintaining soil health. It influences soil pH levels, affecting nutrient availability and uptake by plants. Hydrogen ions in water contribute to soil structure and fertility, fostering a conducive environment for microbial activity and root growth.


Hydrogen is highly important for the growth and maintenance of agricultural lands and plants. The plant needs hydrogen for improved yield and to promote the growth of roots, shoots, and leaves of the plant. These are effectively Involved in respiration and produce the ATP that features the functioning of the plants. However, if the right amount of hydrogen is missing within the soil you can add it by watering the plants daily or also by using ammonia fertilizers. Hydrogen is one of the essential nutrients for plants and their deficiencies will stunt plant growth.
