This chapter proposes that the way forward will be a prosperous and sustainable agriculture sector deeply rooted in the concept of sustainable intensification (SI): producing more with less, using inputs like seeds, fertilizers, and pesticides more prudently, adapting to climate change, reducing GHG emissions, improving natural capital such as soil moisture capacity and the diversity of pests' enemies, and building resilience. One approach to SI is to employ precision agriculture, ensuring that inputs—whether nutrients, pesticides, seeds, or water—are used in a precise, sparing, effective, and strategic way in order to minimize their environmental impact. Thus microdosing permits the prudent, targeted use of inputs such as fertilizers, thereby improving soil quality and moisture while reducing the environmental impact that excessive use can cause. It also reduces costs and helps improve nutrient use efficiency and protection against drought. Precision farming focuses on just one aspect of SI. More generally, it is a concept that includes three mutually reinforcing pillars: ecological intensification, genetic intensification, and socioeconomic intensification.

The exercise of biochar in agribusiness has increased proportionally in recent years. It has been indicated that biochar application could strengthen soil fertility benefits, such as improvement in soil microbial activity, abatement of bulk density, amelioration of nutrient and water-holding capacity and immutability of soil organic matter. Additionally, biochar amendment could also improve nutrient availability such as phosphorus and nitrogen in different types of soil. Most interestingly, the locally available wastes are pyrolyzed to biochar to improve the relationship among plants, soil and the environment. This can also be of higher importance to small-scale farming, and the biochar produced can be utilized in farms for the improvement of crop productivity. Thus, biochar could be a potential amendment to a soil that could help in achieving sustainable agriculture and environment. However, before mainstream formulation and renowned biochar use, several challenges must be taken into consideration, as the beneficial impacts and potential use of biochar seem highly appealing. This review is based on confined knowledge taken from different field-, laboratory- and greenhouse-based studies. It is well known that the properties of biochar vary with feedstock, pyrolysis temperature (300, 350, 400, 500, and 600 °C) and methodology of preparation. It is of high concern to further investigate the negative consequences: hydrophobicity; large scale application in farmland; production cost, primarily energy demand; and environmental threat, as well as affordability of feedstock. Nonetheless, the current literature reflects that biochar could be a significant amendment to the agroecosystem in order to tackle the challenges and threats observed in sustainable agriculture (crop production and soil fertility) and the environment (reducing greenhouse gas emission).
