The soil is an important resource, which sustains life on the planet. However, its contamination with Cadmium (Cd) may represent a huge threat to all the chain of living beings. Efforts have been done to minimize soil pollution with trace metals, as well as to amend those soils that are already polluted. This study was conducted aiming to determine the efficiency of three binding agents on the immobilization of Cd in three soil types collected from Karanganyar. Soil samples were collected from the topsoil (30 cm) and analyzed in the laboratory for pH, SOM, CTC, soil texture and initial Cd content before treatment. The experimental design was Completely Randomized (3 soil types; 3 adsorbents; 3 replications), and incubated for 24 days in the laboratory. After incubation, pH and Cd content were measured and ANOVA and Tukey's test were performed. The results showed that Dolomite was the best binding agent on immobilization of Cd (95.45%) in each soil, followed by organic fertilizer (92.64%) and charcoal (91.53%). However, in general, all the binding agents showed remarkable efficiency on Cd immobilization in the three soil types. To sum up, this research may positively boost agricultural systems, which is determinant for sustainable development, in particular in developing countries worldwide. In addition, the outcomes may have a great impact on the reduction of soil pollution with agrochemicals and heavy metals. On the other hand, there is a potential to keep and restore ecological sustainability. Apart from this, also could minimize to some extent, climate change and global warming issues through multi-planting strategies, while significantly contributing to achieving food security and economic stability, as well as addressing poverty issues in rural areas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
