60 years of fertilization and liming impacts on soil organic carbon stabilization in a sub-tropical Alfisol.

Environ Sci Pollut Res Int 2021 Apr 21. Epub 2021 Apr 21.

Environmental Sciences and Biomedical Metrology Division, CSIR-National Physical Laboratory, New Delhi, 110012, India.

Limited information is available on the C stabilization mechanism of tropical soils under different management practices including long-term organic manuring, mineral fertilization alone, or in combination with lime. Hence, to understand the effect of continuous application (for 60 years) of organic manure, fertilizer, and lime alone or in combination on an acidic Alfisol, stabilization of soil organic carbon (SOC) was evaluated under maize (Zea mays L.) wheat (Triticum aestivum L.

Inoculation of plant growth promoting-methane utilizing bacteria in different N-fertilizer regime influences methane emission and crop growth of flooded paddy.

Sci Total Environ 2021 Jun 13;775:145826. Epub 2021 Feb 13.

Division of Microbiology, ICAR-Indian Agricultural Research Institute, New Delhi 110012, India. Electronic address:

Methane (CH) emission in rice fields is greatly influenced by the type and quantity of nitrogenous fertilizer used. The net methane emission from paddy fields is also influenced by the activity of methane utilizing bacteria, which inhabit the flooded paddy ecosystem. Efficient methane utilizing and plant growth promoting bacteria Methylobacterium oryzae MNL7 and Paenibacillus polymyxa MaAL70, respectively were co-inoculated along with different nitrogenous fertilizer combinations in flooded paddy to assess their impact on cumulative methane emission and crop growth promotion.

Edaphic factors and plants influence denitrification in soils from a long-term arable experiment.

Sci Rep 2020 09 29;10(1):16053. Epub 2020 Sep 29.

Sustainable Agriculture Sciences Department, Rothamsted Research, Harpenden, Hertfordshire, AL5 2JQ, UK.

Factors influencing production of greenhouse gases nitrous oxide (NO) and nitrogen (N) in arable soils include high nitrate, moisture and plants; we investigate how differences in the soil microbiome due to antecedent soil treatment additionally influence denitrification. Microbial communities, denitrification gene abundance and gas production in soils from tilled arable plots with contrasting fertilizer inputs (no N, mineral N, FYM) and regenerated woodland in the long-term Broadbalk field experiment were investigated. Soil was transferred to pots, kept bare or planted with wheat and after 6 weeks, transferred to sealed chambers with or without KNO fertilizer for 4 days; NO and N were measured daily. Read More

Environ Monit Assess 2018 Feb 5;190(3):117. Epub 2018 Feb 5.

ICAR- National Bureau of Soil Survey and Land Use Planning, Amravati Road, Nagpur, Maharashtra, 440033, India.

The ever shrinking agricultural land availability and the swelling demand of food for the growing population fetch our attention towards utilizing partially reclaimed sodic soils for cultivation. In the present investigation, we compared six treatments, like control (T1), existing farmers' practice (T2), balanced inorganic fertilization (T3) and combined application of green gram (Vigna radiate) with inorganic NPK (T4), green manure (Sesbania aculeate) with inorganic NPK (T5), and farmyard manure with inorganic NPK (T6), to study the influence of nutrient management on soil organic carbon sequestration and soil fertility under long-term rice-wheat cropping system along with its productivity in gypsum-amended partially reclaimed sodic soils of semi-arid sub-tropical Indian climate. On an average, combined application of organics along with fertilizer NPK (T4, T5, and T6) decreased soil pH, ESP, and BD by 3. Read More

Responses of Soil Microbial Biomass and Enzyme Activities to Tillage and Fertilization Systems in Soybean ( L.) Production.

Front Plant Sci 2016 21;7:1730. Epub 2016 Nov 21.

Department of Agronomy and Plant Breeding, University of Kurdistan Sanandaj, Iran.

Tillage operation and fertilizer type play important roles in soil properties as far as soil microbial condition is concerned. Information regarding the simultaneous evaluation of the effect of long-term tillage and fertilization on the soil microbial traits of soybean farms is not available.

Division of Soil Science and Agricultural Chemistry, Indian Agricultural Research Institute, New Delhi, 110012, India.

Soil organic carbon plays a major role in sustaining agroecosystems and maintaining environmental quality as it acts as a major source and sink of atmospheric carbon. The present study aims to assess the impact of agricultural management practices on soil organic carbon pools in a maize-wheat cropping system of Indo-Gangetic Plains, India. Soil samples from a split plot design with two tillage systems (bed planting and conventional tillage) and six nutrient treatments (T1 = control, T2 = 120 kg urea-N ha(-1), T3 = T2 (25 % N substituted by FYM), T4 = T2 (25 % N substituted by sewage sludge), T5 = T2 + crop residue, T6 = 100 % organic source (50 % FYM + 25 % biofertilizer + 25 % crop residue) were used for determining the organic carbon pools.

Impact of long-term organic residue recycling in agriculture on soil solution composition and trace metal leaching in soils.

Sci Total Environ 2014 Nov 10;499:560-73. Epub 2014 Jul 10.

INRA, UMR 1091 EGC, Environnement et Grandes Cultures, 78850 Thiverval-Grignon, France.

Recycling composted organic residues in agriculture can reduce the need of mineral fertilizers and improve the physicochemical and biological properties of cultivated soils. However, some trace elements may accumulate in soils following repeated applications and impact other compartments of the agrosystems. This study aims at evaluating the long-term impact of such practices on the composition of soil leaching water, especially on trace metal concentrations. Read More

European Commission, DG - Joint Research Center, Institute of Environment and Sustainability, Via Enrico Fermi 2749, 21027, Ispra, VA, Italy.

Background, Aim, And Scope: Biowaste contains compounds of agricultural value such as organic carbon, nutrients, and trace elements and can partially replace mineral fertilizer (MIN) and improve the physical properties of the soil. However, the obvious benefits of land spreading need to be carefully evaluated against potential adverse effects on the environment and human health. Environmental contamination resulting from biowaste application is one of the key variables when assessing cost/benefits. Read More

Bioresour Technol 2007 Dec 22;98(17):3243-8. Epub 2006 Aug 22.

Institute of Grassland and Environmental Research (IGER), North Wyke Research Station, Okehampton, Devon, UK.

In organic farming, maximising the amount of nitrogen (N) which is fixed and retained within the soil is of paramount importance for the yield of the following crop. The aim of this study was to establish the extent to which increased soil fertility, farmyard manure (FYM) applications and/or mulching, could adversely affect fixation. At two sites, situated in the South West (SW) and North East (NE) of England, N(2) fixation was estimated in 'organically' managed red clover/grass plots, both with and without green manure (i.

Emission of nitrous oxide from rice-wheat systems of Indo-Gangetic plains of India.

Environ Monit Assess 2002 Jul;77(2):163-78

Division of Environmental Sciences, Indian Agricultural Research Institute, New Delhi.

Nitrous oxide (N2O) accounts for 5% of the total enhanced greenhouse effect and responsible for the destruction of the stratospheric ozone. The rice-wheat cropping system occupying 26 million ha of productive land in Asia could be a major source of N2O as most of the fertilizer N in this region is consumed by this system. Emission of N2O as influenced by application of urea, urea plus farm yard manure (FYM), and urea plus dicyandiamide (DCD), a nitrification inhibitor, was studied in rice-wheat systems of Indo-Gangetic plains of India.

Environ Monit Assess 1996 Sep;42(1-2):175-87

Soil Science Department, IACR-Rothamsted, AL5 2JQ, Harpenden, Herts, UK.

Aerobic soils are an important sink for methane (CH4), contributing up to 15% of global CH4 destruction. However, the sink strength is significantly affected by land management, nitrogen (N) fertilizers and acidity. The rates of uptake from the atmosphere of both enhanced (10 ppmv) and ambient (2 ppmv) concentrations of CH4 were measured in laboratory incubations of soil cores under controlled conditions taken from sites in the U.
