Abstract
Modern agricultural practices largely rely on pesticides to protect crops against various pests and to ensure high yields. Following their application to crops a large amount of pesticides ends up in soil where they may affect non-target organisms, among which microorganisms. We assessed the effects of the carbamate nematicide oxamyl on the whole bacterial diversity of an agricultural soil exhibiting enhanced biodegradation of oxamyl through 16S rRNA amplicon next generation sequencing (NGS) and on the oxamyl-degrading bacterial community through cehA q-PCR analysis and 14C-oxamyl mineralization assays. Oxamyl was rapidly mineralized by the indigenous microorganisms reaching >70% within a month. Concomitantly, a significant increase in the number of oxamyl-degrading microorganisms was observed. NGS analysis of the total (DNA) and active (RNA) bacterial community showed no changes in α-diversity indices in response to oxamyl exposure. Analysis of the β-diversity revealed significant changes in the composition of the soil bacterial community after 13 and 30 days of oxamyl exposure only when the active fraction of the bacterial community was considered. These changes were associated with seven OTUs related to Proteobacteria (5), Acidobacteria (1) and Actinobacteria (1). The relative abundance of the dominant bacterial phyla were not affected by oxamyl, except of Bacteroidetes and Gemmatimonadetes which decreased after 13 and 30 days of oxamyl exposure respectively. To conclude, oxamyl induced changes in the abundance of oxamyl-degrading microorganisms and on the diversity of the soil bacterial community. The latter became evident only upon RNA-based NGS analysis emphasizing the utility of such approaches when the effects of pesticides on the soil microbial community are explored.

Impact of an organic formulation (panchakavya) on the bioleaching of copper and lead in contaminated mine soil. CHEMOSPHERE 2015; 138:127-132. [PMID: 26066082 DOI: 10.1016/j.chemosphere.2015.05.059] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2014] [Revised: 05/13/2015] [Accepted: 05/19/2015] [Indexed: 06/04/2023]
Abstract
The study was aimed to evaluate the potential of organic formulation, panchakavya, for enhancing the biological leaching of Pb and Cu in contaminated mine soil. Response surface methodology based Box-Behnken design was used to optimize the variables such as incubation time, panchakavya concentration, and agitation rate. The maximum bioleaching (Pb=64% and Cu=49%) was observed after 54 h of incubation with 10 mL panchakavya at 120 rpm. Statistics-based contour and three-dimensional plots were generated to understand the relationship between Pb and Cu bioleaching and variables. High-performance liquid chromatography analysis showed the presence of lactic (25.88 mg g(-1)), citric (0.14 mg g(-1)), succinic (0.14 mg g(-1)), malic (0.66 mg g(-1)), and acetic (0.44 mg g(-1)) acids in panchakavya, which may have a vital role in the removal of metals from the contaminated soil. Soil fraction studies indicate a significant increase of Pb (45%) in the exchangeable fraction of panchakavya-treated soil. XRD studies confirmed the role of panchakavya induced calcite and other minerals in the precipitation of metal ions. A significant increase in the enzyme activities of phosphatase, dehydrogenase, urease, amylase, invertase, and cellulase were observed in the panchakavya-treated soil.

Influence of insecticides flubendiamide and spinosad on biological activities in tropical black and red clay soils. 3 Biotech 2015; 5:13-21. [PMID: 28324354 PMCID: PMC4327749 DOI: 10.1007/s13205-013-0188-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2013] [Accepted: 11/20/2013] [Indexed: 11/03/2022] Open
Abstract
A laboratory experiment has been conducted to investigate the ecological toxicity of flubendiamide and spinosad at their recommended field rates and higher rates (1.0, 2.5, 5.0, 7.5, 10.0 kg ha−1) on cellulase, invertase and amylase in black and red clay soils after 10, 20, 30 and 40-day exposure under controlled conditions in groundnut (Arachis hypogaea L.) soils of Anantapur District, Andhra Pradesh, India. Flubendiamide and spinosad were stimulatory to the activities of cellulase, invertase and amylase at lower concentrations at 10-day interval. The striking stimulation in soil enzyme activities noticed at 2.5 kg ha−1, persists for 20 days in both soils. Overall, the higher concentrations (5.0–10.0 kg ha−1) of flubendiamide, and spinosad were toxic or innocuous to cellulase, invertase and amylase activities, respectively. The results of the present study thus, clearly, indicate that application of the insecticides in cultivation of groundnut, at field application rates improved the activities of cellulase, invertase and amylase in soils.

Abstract
Introduction of agrochemicals (fungicides) into soil may have lasting effects on soil microbial activities and thus affect soil health. In order to determine the changes in microbial activity in a black clay and red sandy loam soils of groundnut (Arachis hypogaea L.) cultivated fields, a case study was conducted with propiconazole and chlorothalonil to evaluate its effects on soil enzymes (cellulase and invertase) throughout 40 days of incubation under laboratory conditions with different concentrations (1.0, 2.5, 5.0, 7.5, and 10.0 kg ha−1). Individual application of the two fungicides at 1.0, 2.5, and 5.0 kg ha−1 to the soil distinctly enhanced the activities of cellulase and invertase but at higher concentrations of 7.5 and 10 kg ha−1 was toxic or innocuous to both cellulase and invertase activities. In soil samples receiving 2.5–5.0 kg ha−1 of the fungicides, the accumulation of reducing sugar was pronounced more at 20 days, and the activity of the cellulase and invertase was drastically decreased with increasing period of incubation up to 30 and 40 days.

Abstract
Impacts of diazinon, imidacloprid and lindane treatments on dehydrogenase and alkaline phosphomonoesterase enzyme activities were determined in groundnut (Arachis hypogaea L.) field for three consecutive years (1997-1999). Diazinon was applied as both seed and soil treatments but imidacloprid and lindane were used for seed treatments only at recommended rates. Experiments were conducted at Agricultural Research Station Durgapura, Jaipur, Rajasthan, India. Diazinon residues were persist up till 60 days in both the cases. Average half-lives (t(1/2)) of diazinon were found 29.3 and 34.8 days, respectively, for seed and soil treatments. Diazinon seed treatment had no significant effect on dehydrogenase and alkaline phosphomonoesterase enzymes activities. In diazinon soil treatment, there were a significant increase in dehydrogenase and decrease in alkaline phosphomonoesterase activities after 24 h of treatment, which continued till 30 days. In seed treatments, imidacloprid and lindane were present in soil up to 90 and 120 days with average half-lives (t(1/2)) of 40.9 and 53.3 days, respectively. Within 90 days, imidacloprid residues were declined up to 73.17% to 82.49% while decline in lindane residues ranged from 78.19% to 79.86% within 120 days. In imidacloprid seed treated field, both dehydrogenase and phosphomonoesterase activities were increased between 15 and 60 days after sowing. However, a significant decreases in both dehydrogenase and phosphomonoesterase enzyme activities were observed between 15 and 90 days after lindane seed treatment.
