    Considering the importance of nickel and iron nutrition for the soybean crop, their deficiency inhibits the yield drastically specially in the area where soybean crop is dominant. To encounter this problem, a pot experiment was conducted in glass house on low nickel and iron soil in Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, during 2019�20 and 2021�22. The study was carried out to investigate the effect of Ni (nickel) and Fe (iron) on the post-harvest soil parameters, growth, yield, nutrient uptake and nutrient content of soybean crop. There were 10 treatments with two levels of Ni (5 and 10 mg kg ?1) and Fe (10 and 20 mg kg?1) with recommended dosage of fertilizers nitrogen, phosphorus, potassium (8.93, 35.71, and 17.86 mg kg?1) applied to all treatments except control. The result of the experiment revealed that the co-application of nickel and iron@10 mg kg?1 and 20 mg kg?1 (RDF + Ni10Fe20), resulted in the increase in plant height, greeness index, no of seed per pod, no of pod per plant, seed yield, and stover yield. Similar, findings for the post- harvest soil parameter indicated that there was increase in pH, electrical conductivity, and organic carbon content of soil. DTPA (Diethylenetriaminepentaacetic acid) extractable Ni, Fe, Zn, and Cu, also found highest in treatment where nickel and iron@10 mg kg?1 and 20 mg kg?1 (RDF + Ni10Fe20) were applied in soil, but in case of DTPA extractable Mn, the highest amount was found in treatment where nickel and iron@10 mg kg?1 and 10 mg kg?1 (RDF + Ni10Fe10) was applied in soil. The soil microbial biomass carbon and urease activity was also found highest in the treatment where nickel and iron@10 and 20 mg kg?1 was applied in soil. The minimum plant height, greeness index, no of seed per pod, no of pod per plant, seed, and stover yield was recorded in treatment where only RDF(T1) was applied. Similar, result recorded for the post-harvest soil parameters. So, overall findings of the pot experiment revealed that the conjoint application of nickel and iron has resulted in better yield of soybean crop. � 2024 Taylor & Francis Group, LLC.

    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.
