    Nanotechnology: An Efficient Tool in Plant Nutrition Management
    (Nova Science Publishers, Inc., 2022) Sharma, Sachin; Singh, Surendra; Bahuguna, Ayush; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh; Pandey, Astha; Thakur, Rajneesh; Jatav, Hanuman Singh
    The increasing global population accelerates world food demand with limited land resources. It shifts the research towards higher productivity with higher fertilizer use on large scale but with high economic inputs. This promotes the use of Nanotechnology in fertilizer industries which offers higher production with the desired customization in nutrient values, high reactivity, changeable surface area, high nutrient use efficiency because of its different physic-chemical properties. Nanoparticles facilitate a smart delivery system of nutrients with the targeted cellular approach in plants as well as in the rhizosphere. The nanopolymers and nano fertilizers also benefit the plant in stress resistance, crop nutrient quality and improve water use efficiency. However, the behavior of nanoparticles to surpass the food chain, its concentration and toxicity in edible products is still a topic of research. The present chapter deals with their mechanisms, controlled release pattern, particle morphology, chemical kinetics, interaction with soil colloids as well as the effect on the microbiome with lesser amount application in the field and proves to replace the current conventional fertilizers with sustainability and minimal environmental risks. � 2022 by Nova Science Publishers, Inc.

    Soil Pollution Due to Sewage Sludge and Industrial Effluents
    (Springer Science and Business Media Deutschland GmbH, 2022) Bahuguna, Ayush; Singh, S.K.; Sharma, Sachin; Arvind; Pandey, Astha; Dadarwal, Basant Kumar; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh
    In recent times the issue of soil pollution is becoming important as all the nutrient are taken up by plant from the soil. The wastewater treatment produces sewage sludge as an end product, but its primary source is from domestic effluents as well as industrial effluents. Water makes up more than 90% of the sewage water produced in India, 40�50% organics, 30�40% inert compounds, 10�15% bio-resistant organics, and 5�8% miscellaneous components make up the solid fraction. Rapid urbanisation, industrialisation and increasing population generate a huge amount of waste and the waste from industry and the sewage released into the soil as a source of irrigation without being treated properly causes accumulation of toxic heavy metals, persistent organic pollutant, microplastics and high salt that leads to the reduction in the quality of the soil. Similarly, the effluents released by the industries such as distillery, tanning, textile also contains different sources of heavy metals, sodium and other salts and organic chemicals. This chapter providesa detailed aspect of soil pollution from the industry as well as sewage sludge. � 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
