Sugarcane Distillery Spent Wash (DSW) as a Bio-Nutrient Supplement: A Win-Win Option for Sustainable Crop Production

Abstract

Industrial pollution has been continuously soaring and causing serious threats to the soil, water, and air quality. The increase in industrialization has not only covered the large areas, but also created a large quantity of wastewater which is difficult to handle. The water produced from different industries is getting its place in the agriculture. However, the challenge is to properly use wastewater, so that the application of wastewater does not cause any soil and environmental problems. The distillery spent wash (DSW) is a liquid waste that is produced from the sugarcane industry. It contains a large load of both organic and inorganic substances. Also, DSW contains a sufficient amount of macronutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and Sulphur (S)) and micronutrients (zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn)), which in turn improves the growth and yield of crops. The optimized doses of DSW substantially improve soil enzymatic and microbial activities, organic carbon, nutrient uptake, soil porosity, water holding capacity, aggregate stability, and anti-oxidant activities, which in turn improve the photosynthetic efficiency, growth and yield. However, the inadequate knowledge about the DSW characteristics and methods of its agricultural application present questions concerning environmental quality for groundwater pollution. Therefore, to obtain a better understanding about the DWS, here, we discussed the effects of DSW on soil quality, crop yield, and its implications for agriculture and water quality.

“…The natural environment has frequently acquiring metal pollution from the anthropogenic fonts comprising sewage expulsions, mining manoeuvres, phosphate fertilizers and overflows from metal refining industries and other industries (Yang et al, 2006;Liu et al, 2007;Seleiman et al, 2012;Seleiman et al, 2013;Seleiman et al, 2017;Hassan et al, 2019;Seleiman et al, 2020a;Seleiman et al, 2020b;Hassan et al, 2021;Seleiman et al, 2021a). World health organization categorized the heavy metals pollution as the second most adverse pollution because it has severe threats to human health (Salem et al, 2018).…”

Mitigation of Cadmium Induced Oxidative Stress by Using Organic Amendments to Improve the Growth and Yield of Mash Beans [Vigna mungo (L.)]

“…Human activities are the major source of soil contamination with toxic metals and this problem needs special attention to safe humans, animals and plants. The application of sewage water, industrial activities, mining, waste production and heavy application of pesticides are major reasons of soil contamination [2][3][4]. Toxic metals retain in soil and affect the soil microbes and plant growth and subsequently transferred into plants and impact the human health by entering the food chain [5].…”

“…Press-mud is produced in larger quantities as a by-product from the sugar industry [4,28] and it is considered a good soil conditioner [29,30]. The mixing of rock phosphate with press-mud substantially reduces the bio-availability of toxic metals [29].…”

Harnessing the potential of sugarcane-based liquid byproducts—molasses and spentwash (vinasse) for enhanced soil health and environmental quality. A systematic review

“…Vinasse has been found to promote various plant physiological processes, enhancing photosynthesis rate, stomatal conductance, and respiration rate, leading to improved CO 2 utilization, water regulation, and macromolecule synthesis and distribution in plants (Naveed et al, 2018). Furthermore, vinasse contains plant growth-promoting hormones (PGPHs) such as Gibberellic acid (GA), Indole acetic acid (IAA), Abscisic acid (ABA), Zeatin (Z), cis-zeatin riboside (c-ZR), isopentenyladenine (iP), and isopentenyladenosine (iPR), which contribute to enhanced plant growth and yield (Khan et al, 2020;Hassan et al, 2021;Zamarreño et al, 2022).…”
