INM in Forage Sorghum: Organic, Inorganic & Biofertilizer

Forage sorghum is a versatile crop that is widely grown for its high biomass production and nutritional value. To maximize the growth and yield of forage sorghum plants, farmers often rely on the use of fertilizers. In this article, we will explore the different types of fertilizers that can be used in forage sorghum cultivation, including organic, inorganic, and biofertilizers.

Organic Fertilizers

Organic fertilizers are derived from natural sources such as animal manure, compost, and plant residues. These fertilizers provide a slow-release of nutrients to the soil, promoting long-term soil fertility and improving the overall health of the plants. Organic fertilizers also enhance the soil structure, water-holding capacity, and microbial activity, leading to improved nutrient uptake by the forage sorghum plants.

Benefits of Organic Fertilizers

  • Environmentally friendly
  • Improve soil fertility
  • Enhance nutrient availability
  • Promote beneficial microbial activity
  • Reduce the risk of nutrient leaching

Inorganic Fertilizers

Inorganic fertilizers, also known as synthetic fertilizers, are manufactured using chemical processes. These fertilizers provide a quick-release of nutrients to the plants, ensuring rapid growth and development. Inorganic fertilizers are highly concentrated and can be easily customized to meet the specific nutrient requirements of forage sorghum. However, excessive use of inorganic fertilizers can lead to nutrient imbalances and environmental pollution.

Benefits of Inorganic Fertilizers

  • Immediate nutrient availability
  • Highly customizable nutrient composition
  • Enhanced plant growth and yield
  • Convenient application methods


Biofertilizers are living organisms that enrich the soil with beneficial microorganisms, such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and mycorrhizal fungi. These microorganisms form symbiotic relationships with the forage sorghum plants, enhancing nutrient uptake and promoting plant growth. Biofertilizers are environmentally friendly and can improve soil fertility in the long run.

Benefits of Biofertilizers

  • Natural and sustainable
  • Enhance nutrient availability
  • Improve soil structure
  • Reduce the need for chemical fertilizers
  • Promote plant growth and yield

Frequently Asked Questions

1. Can I use a combination of organic, inorganic, and biofertilizers?

Yes, it is possible to use a combination of different types of fertilizers to meet the specific nutrient requirements of forage sorghum. However, it is important to carefully monitor the nutrient levels in the soil to avoid nutrient imbalances.

2. How often should I apply fertilizers to forage sorghum?

The frequency of fertilizer application depends on various factors, including soil fertility, crop growth stage, and nutrient requirements. It is recommended to conduct soil tests and consult with agricultural experts to determine the appropriate fertilizer application schedule.

3. Are there any alternatives to chemical fertilizers?

Yes, organic fertilizers and biofertilizers are considered alternatives to chemical fertilizers. These options provide sustainable and environmentally friendly ways to enhance soil fertility and promote plant growth.


The use of fertilizers, whether organic, inorganic, or biofertilizers, can greatly benefit the growth and yield of forage sorghum plants. Each type of fertilizer has its own advantages and considerations. By understanding the different options available, farmers can make informed decisions to optimize the cultivation of forage sorghum and ensure sustainable agricultural practices.
