Pavel Suran, Jiří Balík, Martin Kulhánek, Ondřej Sedlář, Jindřich Černý

Plant Soil Environ., 2024, 70(2):93-100 | DOI: 10.17221/493/2023-PSE  

In recent years, sulfur inputs into the soil have greatly diminished due to the significant decrease in SO2 emissions. Plant nutrients, like sulfur, can be released by the mineralisation of soil organic matter (SOM), which is a complicated mixture of substances (or fractions) like glomalin-related soil protein (GRSP) and fulvic acids (FA), humic acids (HA), humic substances (HS) and others. GRSP, FA, HA, and HS content, as well as the content of mineral and organic fractions of sulfur, was determined in different mineral and organic fertiliser treatments of the long-term field experiment. Using these results, the sulfur content in GRSP was...

Xue Zhang, Xiaodong Yu, Yunxiao Cao, Jiani Yue, Shan Wang, Yunxia Liu

Plant Soil Environ., 2024, 70(1):48-59 | DOI: 10.17221/340/2023-PSE  

Arbuscular mycorrhizal fungi (AMF) play a key role in regulating the carbon cycle in terrestrial ecosystems. However, there is little information on how AMF inoculation affects the carbon fluxes of paddy fields, which are major sources of global carbon emissions. We, therefore, designed an experiment to study the effects of AMF inoculation on methane and carbon dioxide emissions from a paddy field. Results showed that: (1) Among the tested factors, the C/N ratio was the main environmental determinant of microbial community structure in the investigated soil; (2) compared with traditional fertilisation (control), the soil C/N ratio increased by 2.1~15.2%...
