Fiber optic technology changes the game by offering real-time, continuous monitoring of critical soil parameters, such as moisture levels, temperature, and nutrient content. With precision fertilization critical for efficient resource use, rapid technological progress in this field has highlighted a gap in consolidated overviews of post-2020 developments. Fiber optic sensors are embedded directly into the soil, where they use light signals to detect changes in these parameters. Precision water and fertilizer application technologies have emerged as crucial innovations in sustainable agriculture, addressing the pressing need to enhance crop yield and quality while optimizing resource use and minimizing environmental impacts. This review systematically explores the latest. Balanced N-P-K ratio is crucial for Fiber Optic Grass nutrition. liquid fertilizers: Choose based on growth needs. The N-P-K ratio on a fertilizer label shows the. Using of fertilizes in agriculture is useful for enhancing food production but on the other side it may be very dangerous for environment because of over and over use of chemical fertilizers, insecticides, herbicides, pesticides and oxytocin. 6 billion by 2050, necessitate the development of highly eficient agriculture while reducing global poverty and hun-ger.
