Application Of Bentonite In Agriculture: 

Are you a farmer looking for an effective and natural solution to enhance the quality of soil and quantity of crop yields? Bentonite is the one-stop solution to all these issues. 

Bentonite is a form of clay that is derived from volcanic ash deposits which have aged over time to turn into bentonite clay. It is rich in nutrients, minerals, and other beneficial compounds that can improve soil fertility and health.

Humans have used bentonite clay for thousands of years as a sustainable solution for the improvement of soil and crop health. It is commonly used as a natural fertilizer and soil conditioner. Bentonite can increase soil’s water retention, improve soil structure, and add the necessary nutrients to crops. This can lead to an improvement in crop quality, an increase in yields, and an overall healthier agricultural operation. 

How Bentonite Aids In Soil Improvement? 

Soil quality is the ability of the soil to sustain the productivity, diversity, and environmental services that meet the needs of human and non-human life. Soil quality is the physical, chemical, and biological characteristics of the soil. 

Soil quality is a key factor in the production of crops as it affects the availability of nutrients and water to plants, as well as the plants’ resistance to pests and various illnesses. Good quality soil has high adsorption and absorption of water and nutrients and has a healthy biological ecosystem. This lets plants grow and thrive and leads to an increase in crop yields. 

Soil quality can degrade due to erosion, compaction, nutrient depletion, and pollution. When soil is exposed to air or water, it can lead to the loss of topsoil, the most fertile layer of the soil. 

The following are the many ways in which bentonite helps in soil improvement:

  • Increase Water Retention: 

Adding bentonite to the soil can improve the soil’s ability to retain water, which is important for plant growth. It helps ensure that plants can have access to water whenever they need it. This is especially important in drought-prone areas, dry climates, and desert areas, where water is scarce. 

  • Increase Nutrient Availability: 

Bentonite can bind and hold onto cations of potassium and calcium, which helps to keep water in the soil. Bentonite can help to increase nutrient availability. It also promotes soil health, reduces the use of synthetic pesticides and fertilizers, contributes to a more sustainable and eco-friendly agricultural system, and helps increase crop yields by up to 20%. 

  • Improve Soil Drainage & Structure: 

Bentonite helps to improve drainage in soil by absorbing excess water and slowly releasing it. This also helps to prevent waterlogging. Soil structure can be improved by adding bentonite clay. When bentonite gets wet, it forms a gel-like structure which helps in binding soil particles together. This is particularly helpful in drought-prone areas and sandy soils. 

  • Improve Soil Quality: 

Bentonite can improve soil quality by increasing soil porosity. The porosity of the soil is the percentage of soil made up of empty spaces, which are key for air and water movement through the soil. Adding bentonite to the soil can help improve soil porosity by increasing the absorption of nutrients and water. 

  •  Reduce Soil Erosion: 

Bentonite can help avoid soil erosion. Soil erosion is the process of soil being washed or blown away by water or wind. It is a grave problem because it can lead to the loss of topsoil, which is the most fertile layer of the soil. Bentonite can reduce erosion by creating a barrier against water and wind and by binding soil particles together. 

  • Promote Beneficial Microorganisms: 

Bentonite can help increase soil organic matter, which supports the growth of beneficial microorganisms. For example, nitrogen-fixing bacteria and mycorrhizal fungi are important for plant health and nutrition. It can lead to increased soil fertility and carbon isolation. 

  • Use As Fertilizer: 

Bentonite can be used as a fertilizer as it is a natural carrier for essential nutrients such as phosphorus, nitrogen, and potassium. There are critical nutrients for plant health and development. Unlike traditional fertilizers, bentonite has the unique ability to slow-release these nutrients over time, which provides a sustained source of nourishment for plants. This promotes plant health and enhances soil fertility. 

  • Improve Nutrient Recycling: 

Bentonite can be used to improve the composting process by increasing the adsorption of excess ammonia and reducing odors in farm animals’ waste. It plays an important role in waste management and reduction in environmental pollution.
