    Nanotechnology for Soil Health: Applications, Improvements, and Environmental Benefits
    (Springer, Singapore, 2026) P. Smriti Rao, Faria Fatima, Abdul Mazeed, Saba Siddiqui, Mohammed Haris Siddiqui
    Agriculture provides sustenance and raw materials to the building, energy, fabric, and pharmacological industries. Agrochemical overuse, soil degradation, urbanization, unsustainable resource use, biodiversity loss, air pollution, and climate change are just a few of the worrisome problems facing agriculture today that demand prompt attention. These problems are too complex, labor-intensive, time-consuming, inefficient, demand a lot of crop nutrients, and are not suited for conventional agricultural methods to handle. Furthermore, the excessive use of agrochemicals poses a serious threat to ecological integrity. As a result, researchers, farmers, and decision-makers are never done looking for innovative ways to address pressing issues. Growing evidence points to nanotechnology as the new sustainable agricultural savior. Nanosensors have been used in agri-fields not only for precision farming but also for the recognition of chemically hazardous analytes and crop diseases. Additionally, there are many amazing uses of nanotools in agriculture, including sensing, photocatalysis, and the delivery of agrochemicals. This chapter covers in detail the many amazing ways that nanotechnology has been used to overcome the shortcomings of traditional agronomic approaches as well as the potential applications that nanotechnology may have in the future.

    Nanofertilizers for Plant Nutrition
    (Springer, Singapore, 2026) P. Smriti Rao, Faria Fatima, Abdul Mazeed, Munny Chinyo, Khalid Habib
    In a startling saga of agricultural overabundance, the once-fertile soil has suffered greatly from the pervasive use of synthetic fertilizers in contemporary agricultural practices, which has severely depleted its essential nutrients and irreversibly damaged the vital equilibrium of the surrounding environment. Overuse of these fertilizers degrades soil quality, pollutes the environment, disturbs agrarian ecosystems, and deposits residue on agricultural products. Moreover, between 50 and 70% of the nutrients including potassium, phosphate, and nitrogen are lost from the soil before they can be used. Nanoparticles regulate nutrient delivery, making nanofertilizers more economical and efficient than conventional fertilizers. A new class of fertilizers called nanofertilizers makes use of cutting-edge nanotechnology to offer a potent and eco-friendly approach to crop fertilization. They ensure that nutrients are distributed uniformly over an extended period of time with their regulated nutrient delivery system, providing plants that provide a consistent flow of vital components. Because it requires less fertilizer and less frequent management, the regulated discharge technology works better than standard fertilizers. In agriculture, nanotechnology is primarily utilized to enhance crop yields, reduce losses, and stimulate plants to defend against pests, insects, and environmental challenges. Nanofertilizers have shown promising results in various plant species, whether applied topically or in the soil. Most nanomaterials are precursors of macro- and micronutrients and their nanoscale properties. This chapter explores new approaches to using them as crop growth promoters, as well as how to apply and incorporate them into plant matter. It also discusses future concerns and possible drawbacks for the commercial implementation of nanofertilizers in agriculture.
