About this Research Topic
Our agricultural land is a finite resource suffering from irreversible damage due to anthropogenic activities over the last few decades. On one hand, there is pressure on the scientific community to develop new technological interventions which can help meet the demands of a growing population for food, fiber and shelter. While on the other hand, most of these interventions have profound impacts on the health of agricultural lands due to the addition of pollutants like pesticides, metals and metalloids, persistent organic pollutants, radionuclides, PHAs etc. Furthermore, new emerging pollutants such as microplastics, antibiotics, disinfectants, insect repellents, flame retardants, and nanoparticles, etc. have further aggravated the situation. According to estimates over 75% of the Earth's land areas have been substantially degraded and most of which require centuries to bring them back to their normal state.
The international scientific community has realized the severity of the problem at hand and efforts are being made on different fronts to address this multidimensional issue. Different sorption-based techniques have been tested and used to improve soil health and reduce the toxicity level of polluted lands like in-situ immobilization/stabilization, microbial sorption and degradation, organic additives (like activated carbon, biochar, hydrochars, bio-wastes etc), bioavailability, and toxicity reduction, and physical separation and extraction. Extensive studies are being carried out to address the issue but most of the studies are still being conducted in labs. There is a need for pilot or full field-scale studies to test these latest technologies. So far, in the few cases where lab studies have been replicated in the field, the results were either have been either negligible or negative.
This Research Topic aims to focus on the latest cutting-edge research to shed light on the technologies, procedures, protocols which can help to control and mitigate the impacts of pollution on agricultural land. We welcome all article types with an emphasis on Original Research and Review articles concerning:
- Novel soil remediation techniques;
