Metal(loid)s (As, Hg, Se, Pb and Cd) in paddy soil: Bioavailability and potential risk to human health.
Rubina Khanam,Anjani Kumar,Amaresh Kumar Nayak,Shahid,Rahul Tripathi,Subramaniyan Vijayakumar,Debarati Bhaduri,Upendra Kumar,Sangita Mohanty,Periyasamy Panneerselvam,Dibyendu Chatterjee,B.S. Satapathy,H Pathak +12 more
TL;DR: This review summarizes mobilization, translocation and speciation mechanism of these metal(loids) in soil-plant continuum as well as available cost-effective remediation measures and future research needs to eliminate the long-term risk to human health.
Journal ArticleDOI
Long-term effect of different integrated nutrient management on soil organic carbon and its fractions and sustainability of rice–wheat system in Indo Gangetic Plains of India
Amaresh Kumar Nayak,Bhanu P. Gangwar,Arvind Kumar Shukla,Sonali P. Mazumdar,Anjani Kumar,R. Raja,Anil Kumar,Vinod Kumar,Praveer Rai,Udit Mohan +9 more
TL;DR: In this article, the effect of different integrated nutrient management practices on soil organic carbon (SOC) stocks and its fractions, SOC sequestration potential as well as the sustainability of the rice-wheat system were evaluated in long term experiments at different agro-climatic zones of IGP.
Journal ArticleDOI
Soil aggregation and distribution of carbon and nitrogen in different fractions after 41years long-term fertilizer experiment in tropical rice–rice system
Rahul Tripathi,Amaresh Kumar Nayak,Pratap Bhattacharyya,Arvind Kumar Shukla,Mohammad Shahid,R. Raja,B.B. Panda,Sangita Mohanty,Anjani Kumar,V.K. Thilagam +9 more
TL;DR: In this article, the authors investigated the long-term effects of fertilizer and manure application on the distribution of water stable aggregates in the soil and the amount of total soil organic carbon (TOC), total N and C/N ratio in different aggregate fractions.
Journal ArticleDOI
Variation of functional diversity of soil microbial community in sub-humid tropical rice-rice cropping system under long-term organic and inorganic fertilization
Upendra Kumar,Mohammad Shahid,Rahul Tripathi,Sangita Mohanty,Anjani Kumar,Pratap Bhattacharyya,Banwari Lal,Priyanka Gautam,R. Raja,R. Raja,B. B. Panda,NN Jambhulkar,Arvind Kumar Shukla,Amaresh Kumar Nayak +13 more
TL;DR: In this paper, the long-term effects of organic and inorganic fertilizers on functional diversity of soil microbial communities, and their correlation with soil organic carbon, microbial biomass and activities, were observed under sub-humid tropical rice-rice cropping system.
Journal ArticleDOI
Continuous application of inorganic and organic fertilizers over 47 years in paddy soil alters the bacterial community structure and its influence on rice production
Upendra Kumar,Upendra Kumar,Amaresh Kumar Nayak,Mohammad Shahid,Vadakattu V. S. R. Gupta,Periyasamy Panneerselvam,Sangita Mohanty,Megha Kaviraj,Anjani Kumar,Dibyendu Chatterjee,Banwari Lal,Priyanka Gautam,Rahul Tripathi,B. B. Panda +13 more
TL;DR: Overall, the present study indicated that continuous application of N and NPK with or without FYM for more than four decades in paddy soil, encouraged certain BCS whereas, N application alone suppressed certain beneficial bacterial phyla, resulting in the alteration of soil biodiversity and rice productivity.
