Biochar has the potential to produce farm-based renewable energy in an eco-friendly way. Specifically, the quality of biochar depends on several factors, such as the type of soil, metal, and the raw material used for carbonization, the pyrolysis conditions, and the amount of biochar applied to the soil.
In addition, the biochar amendment to the soil proved to be beneficial to improve soil quality and retain nutrients, thereby enhancing plant growth. Since biochar contains organic matter and nutrients, its addition increased soil pH, electric conductivity (EC), organic carbon (C), total nitrogen (TN), available phosphorus (P), and the cation-exchange capacity (CEC).
Earlier, reported that the biochar application affected the toxicity, transport, and fate of various heavy metals in the soil due to improved soil absorption capacity. The presence of plant nutrients and ash in the biochar and its large surface area, porous nature, and the ability to act as a medium for microorganisms have been identified as the main reasons for the improvement in soil properties and increase in the absorption of nutrients by plants in soils treated with biochar.

Biochar application decreased the tensile strength of soil cores, indicating that the use of biochar can reduce the risk of soil compaction. A lot has already been discussed on the benefits of inoculation of rhizobacteria in soil, but the addition of biochar can also provide more nutrients to the soil, thus benefiting the agricultural crops. The mixing of the plant growth-promoting microorganisms with biochar was referred to as the best combination for growth and yield of French beans Therefore, all statements are correct.
Therefore, the correct answer is (d).
Therefore, the correct answer is (d).

Biochar is used in farming to improve soil fertility, increase crop yields, and reduce greenhouse gas emissions. It is a form of charcoal that is produced by heating organic materials such as wood, crop residues, and manure in the absence of oxygen. When added to soil, biochar can enhance soil structure, increase water retention, and reduce nutrient leaching. It can also provide a habitat for beneficial microorganisms that can help plants to grow. Additionally, biochar can sequester carbon in the soil, reducing the amount of greenhouse gases in the atmosphere. Overall, the use of biochar in farming can improve soil health and productivity while also contributing to climate change mitigation efforts.
