Biochar is a multifunctional biomaterial with many important uses in agriculture, particularly as a biofertilizer. This chapter discusses the unique features of biochar that have made it a valuable biofertilizer, highlighting its potential to support a number of microbial communities in the soil, suppress plant diseases, and contribute to sustainable crop growth. The impact of biochar on plant growth is being investigated, with an emphasis upon how it may encourage the formation of roots, retention of water, and nutrient retention – all of which in turn lead to higher agricultural yields. Biochar’s dual purpose as a microbial inoculant carrier increases its value as a biofertilizer through offering a substrate which boosts the longevity as well as efficiency of advantageous microorganisms in the environment. The chapter compares modern pyrolysis techniques to traditional biochar production techniques such as pit and mound burning. Conventional approaches are readily available and inexpensive, but they are less effective and produce greater amounts of pollutants. With higher temperature and combustion rate control achievable by means of advanced pyrolysis, biochar with higher permeability, pore size, and nutritional value can be produced, improving its uniformity and sustainability as a biofertilizer. A comparative investigation illustrates the long - term benefits of organic fertilizers, such as biochar, over chemical alternatives, highlighting their ability to enhance agricultural resilience and their lesser environmental impact. The section covers the physical and chemical properties of the biochar of the biochar, including its surface structure, porosity, and amount of nutrients, which maximize its interactions with soil. In addition to promoting the use of biochar in agricultural systems to improve soil health, reduce disease pressure, and advance sustainable agriculture, this chapter ends with research directions for the future.
