![]() ![]() bispinosa is a fast-growing plant with nitrogen-fixing root nodules widely grown in the northern regions of India. Sesbania bispinosa, commonly known as “dhaincha” in India and Bangladesh, is a deciduous shrub or small tree native to tropical and subtropical parts of Asia, Africa, and the Americas. Several authors have developed mathematical models for efficient monitoring and optimization of the SS dose for sustainable crop cultivation without causing health risks to consumers. However, the SS must be carefully managed to ensure that heavy metals and other contaminants do not accumulate in the soil or crop plants. Efficacious results were obtained by other researchers when cultivating tomatoes ( Lycopersicon esculentum Mill.), pea ( Pisum sativum L.), mung bean ( Vigna radiata L.), and okra ( Abelmoschus esculentus (L.) Moench) crops using varying doses of SS in both pot-type and open-field experiments. When applied to agricultural land, SS can improve the soil’s fertility, reduce the need for chemical fertilizers, and improve crop yields. Recent studies have reported that SS can provide major plant nutrients, such as N, P, and K, as well as other essential trace elements including copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn). Reusing SS for crop cultivation is a viable way to recycle the nutrients and organic matter (OM) contained in SS back into the soil. Moreover, SS can also be reutilized in a variety of ways, including composting, application to land, resource recovery, and energy recovery. In particular, research communities have reported that physical (filtration, settling, and dewatering), chemical (addition of chemicals to reduce pollutants and pathogens), and biological (use of bacteria and other microorganisms to degrade pollutants and pathogens) are among the top methods for efficient SS management. However, the most common approach to SS management is to treat it before disposal, which can be accomplished through several methods, including physical, chemical, and biological treatments. Nowadays, SS management is a major environmental and economic problem, as its unsafe disposal can cause serious environmental and health risks, including contamination of the soil and water sources. Sewage sludge (SS), being a by-product of the urban wastewater treatment process, contains a variety of organic and inorganic elements, including carbon (C), nitrogen (N), phosphorus (P), potassium (K), and heavy metals. bispinosa fiber production that could minimize the environmental pollution caused by the unsafe disposal of SS. The study suggested a sustainable approach for efficient soil fertilization and high-quality S. The findings showed that soil amended with SS significantly ( p Mn > Zn > Cu > Cd > Cr. Field experiments were conducted using different doses of SS such as 0% (T0), 5% (T1), 10% (T2), and 15% (T3) to amend the soil ( w/ w). In this study, the potential use of sewage sludge (SS) as a fertilizer source for cultivated Dhaincha ( Sesbania bispinosa (Jacq.) W.Wight) crops was investigated. ![]()
