Low-input agricultural systems aim at reducing the use of synthetic fertilizers and pesticides in order to improve sustainable production ecosystem health. Despite integral role soil microbiome production, we still have a limited understanding complex response microbial diversity organic conventional farming. Here report on structural more than two decades different management long-term field experiment using high-throughput pyrosequencing approach bacterial fungal ribosomal markers. Organic...
ABSTRACT The impact of land use intensity on the diversity arbuscular mycorrhizal fungi (AMF) was investigated at eight sites in “three-country corner” France, Germany, and Switzerland. Three were low-input, species-rich grasslands. Two represented low- to moderate-input farming with a 7-year crop rotation, three high-input continuous maize monocropping. Representative soil samples taken, AMF spores present morphologically identified counted. same also served as inocula for “AMF trap...
Soil quality is defined as the capacity of soil to perform multiple functions, and can be assessed by measuring chemical, physical biological parameters. Among parameters, labile organic carbon considered have a primary role in many functions related productivity environmental resilience. Our study aimed at assessing suitability different fractions, namely dissolved (DOC), hydrophilic DOC (Hy-DOC), permanganate oxidizable (POXC, also referred Active Carbon), hot water extractable (HWEC)...
Abstract Communities of arbuscular mycorrhizal fungi (AMF) in five agricultural field sites different management intensities were studied. Variable regions the ribosomal RNA genes used to detect and identify AMF directly within colonized roots. Roots from a continuous maize monoculture showed low diversity, agreement with previous reports on molecular diversity soils. In contrast, substantially higher was found throughout long term ‘DOK’ experiment, where organic conventional practices have...
The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various taxa are currently used as biofertilizers, based on their capacity access nutrients from fertilizers soil stocks, fix atmospheric nitrogen, improve water uptake or act biocontrol agents. Despite existence considerable knowledge effects specific comprehensive...
In this study the influence of different farming systems on microbial community structure was analyzed using soil samples from DOK long-term field experiment in Switzerland, which comprises organic (BIODYN and BIOORG) conventional (CONFYM CONMIN) as well an unfertilized control (NOFERT). We examined communities winter wheat plots at two points crop rotation (after potatoes after maize). Employing extended polar lipid analysis up to 244 phospholipid fatty acids (PLFA) ether lipids (PLEL) were...
Abstract Consumers have become more aware of healthy and safe food produced with low environmental impact. Organic agriculture is particular interest in this respect, as manifested by 5.768 million hectares managed pursuant to Council Regulation (EEC) 2092/91 Europe. However, there can be a considerable risk that the avoidance chemical inputs organic farming will result poor quality. Here results study on quality wheat ( Triticum aestivum L.) grown 21 year agrosystem comparison between...
Abstract Agricultural practices contribute considerably to emissions of greenhouse gases. So far, knowledge on the impact organic compared non-organic farming soil-derived nitrous oxide (N 2 O) and methane (CH 4 ) is limited. We investigated N O CH fluxes with manual chambers during 571 days in a grass-clover– silage maize – green manure cropping sequence long-term field trial “DOK” Switzerland. two systems biodynamic (BIODYN) bioorganic (BIOORG) solely mineral fertilisation (CONMIN) mixed...
In 2007 two long-term trials were established in Kenya to contribute research-based evidence the global debate on productivity, economic viability and sustainability of different agricultural production systems. These compare conventional (Conv) organic (Org) farming systems at high low input levels locations, i.e. Chuka, with Humic Nitisols, inherent soil fertility rainfall, Thika, Rhodic Nitisols rainfall. The (High) represent commercial-scale, export-oriented that uses recommended amounts...
