In agriculture, biochar is mainly used to increase crop nutrition, plant growth, and soil fertility. It consequently increases farming productivity as a whole. Additionally, it will enable agriculture to use less water and improve plant growth. Application of biochar to agricultural soils has demonstrated to significantly alter the interaction between plants and soil and primarily result in a quantitative increase in agricultural output through physical, chemical, and biological mechanisms.
By converting the carbon in biomass into stable carbon structures in biochar, which can remain stored in soil for hundreds or even thousands of years, sustainable biochar systems can be carbon negative. As a result, there is a net reduction in atmospheric CO2. Producing biochar actually lowers atmospheric CO2 because it converts a naturally occurring organic matter decaying process that would otherwise be carbon-neutral into a carbon-negative process.
Numerous studies have been conducted to lower the cost and raise the standard of livestock feeding. It has been demonstrated that adding biochar to the diets of livestock has a number of positive effects, including improved animal health, increased nutrient intake effectiveness, and increased productivity. Animals gain weight more quickly when biochar is added to their diet, which increases feed efficiency.
Pollutant removal is improved by biochar, which also serves as a soil amendment, adsorbent, redox control agent, and nutritional supplement. Under various circumstances, biochar can improve its capacity for decontamination and for the removal of pollutants.
Improved soil quality and the possibility of carbon trading for the most stable forms are two advantages that carbon-rich soil amendments like biochar provide to horticulture. One of the key characteristics of biochar is its capacity to retain soil nutrients. By adding it to soils, it can increase soil fertility, sequester carbon, and improve soil health. However, there is a need to determine the best way to apply biochar to increase crop yields.
