“…In Brazil, the volume of tannery sludge generated by the industry is approximately 150 -200 kg per ton of leather (dry basis). This waste usually contains a high amount of chromium (Cr) that is deposited in the environment and can result in environmental contamination and, consequently, affect the food chain (Singh et al, 2015;Silva et al, 2010). Some studies have proposed the agricultural use of composted tannery sludge as an alternative treatment method like that of other similar solid waste (Singh et al, 2015;Singh, Singh, Ibrahim, & Hashim, 2011;Silva et al, 2010).…”

Chromium (Cr) accumulation in soil and plants has been reported after successive applications of tannery sludge, which is a matter of concern because Cr can promote environmental contamination and affect the food chain. In this study, we evaluated the growth of and Cr accumulation in maize and cowpea after seven years of consecutive applications of composted tannery sludge (CTS) under field conditions. The experiment consisted of application of CTS at five levels: 0 (control), 2.5, 5, 10, and 20 Mg ha-1 (dry basis). The growth of and Cr accumulation in maize and cowpea were evaluated at 75 and 65 days after plant emergence, respectively. CTS application increased the shoot biomass of maize and cowpea. Accumulation of Cr was similar for both plant species, with higher accumulation in roots. However, Cr accumulation in grains differed as the CTS doses increased; cowpea accumulated more Cr while maize did not accumulate more Cr in grains with higher CTS doses. In conclusion, application of CTS led to higher growth of maize and cowpea plants, and both species exhibited similar Cr accumulation in roots and shoots.

“…On the other hand, over the years, the biological and biochemical properties of soil have gained importance in assessing the sustainability of ecosystems (Singh et al, 2015). Soil microorganisms play an important role in organic matter mineralization, nutrient recycling, and energy flow processes in biogeochemical cycles (Ferreira et al, 2016).…”

Short-term amendment of biosolid on agricultural soil: effects on C and N mineralization and microbial activity

et al. 2022

Adding biosolids to agricultural soils can improve its quality through increased storage of C and N. A study to analyze the short-term impact of the addition of biosolids on the release of nutrients and the microbial activity in agricultural soil was carried out. The microbial biomass C (MB-C), urease activity (UA), and mineralization of N and C at different application rates of biosolids were evaluated (0 mg, 100mg and 200 mg of N-NH4+ kg-1). In addition, a biosolid-only treatment was tested. It was observed an increase in C and N mineralization, NH3 volatilization, and MB-C content, according to the application rate of biosolids. In biosolid treatments, UA increased 100% on average in the first seven days of incubation. These results suggest that the nutrient content in the soil is improved and microbial activity is positively stimulated.

“…Tannery sludge from leather industries is rich in important nutrients for plants, including nitrogen (N), calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), and sulfur (S). However, the presence of chromium (Cr) and sodium (Na) in its chemical composition may restrict its use in agriculture (Singh et al, 2015;Silva et al, 2010).…”
