Plant Soil Environ., 2024, 70(3):125-141 | DOI: 10.17221/199/2023-PSE 
In the present study, a field establishment was initiated in 2018 with eight treatment conditions using biochar application rates of 0, 10, 20, or 30 t/ha and nitrogen application rates of 0 or 150 kg/ha. After two years, the impact of biochar on carbon-nitrogen distributions, soil aggregate stability, and wheat yields was then assessed. The predominant mechanical aggregates after two years were > 5 mm and 2–5 mm granular aggregates, with notable increases in the amounts of these aggregates following the application of biochar with or without nitrogen that coincided with an increase in soil aggregate mechanical stability. Relative to control...

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...

Global climate change leads to frequent occurrence of low-temperature stress (LTS), which poses a serious threat to global food security. Here, environment-control phytotron experiments were conducted on cold-responsive cv. XM26 and cold-tolerant cv. YN19 during the anther differentiation period. Six LTS levels (4, 2, 0, −2, −4, −6 °C) and a control treatment (10 °C) were set to study the effects of different levels of LTS on wheat seed-setting characteristics and yield. LTS significantly decreased grain number per spike, 1 000-grain weight, and grain yield per plant (GYPP) of the two wheat cultivars. Each spike’s grain...

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%...

Drought stress is one of the major threats to food security in the climate change scenario. Reducing the deleterious impacts of drought stress on the productivity of cereal crops is crucial. Hence, limited information has been available about the effect of the combined use of plant growth regulators and mineral fertilisers on promoting drought tolerance in maize seedlings. In this study, a pot experiment was carried out to evaluate the potential of sole or combined application of silicon (Si) and putrescine (Put) to mitigate the detrimental effects of drought on maize. The experimental treatments were, i.e. control (CK), water spray, 4.0 mmol Si, 0.5...

Foliar application of selenium (Se) is an effective measure to increase Se concentrations in peanut pods. However, how the foliar application of amino acid-chelated selenite affects the photosynthetic characteristics of peanut leaves at the podding stage is still unclear. Here, the effects of Se on the activities of antioxidant enzymes, the concentrations of chlorophyll, soluble protein, soluble sugar, and reduced glutathione (GSH), photosynthetic parameters, and Se concentration of peanut leaves were investigated by spraying selenite, L-lysine-chelated selenite, and amino acid-chelated selenite solutions, respectively. The results indicated that foliar...

Due to its positive effects, mulching with organic matter is a popular soil conservation tool. However, opinions are divided on the effects of mulching on pests and pathogens. Our research aimed to investigate the effect of organic mulch on potato tuber damage caused by soil-dwelling pests and soil-borne pathogens. Therefore, mulching trials were carried out at four sites over six years, comparing the effects of straw, walnut leaves, mixed leaves, compost and two sowing methods (in soil, on soil surface, and under mulch). The total yield of the mulched plots was equal (2013, 2014) or significantly higher (2015, 2016, 2017, 2018) than the control, while...

Most farmers use urea as a nitrogen fertiliser to raise mustard (Brassica juncea L.), although its nitrogen (N) content is quickly lost due to its hygroscopic nature. Nitrogen loss in the form of nitrous oxide (N2O) and nitrates (NO3–) has been causing low nitrogen fertiliser efficiency in vegetable cultivation. This investigation aims to assess the impact of urea fertiliser coated with biochar or activated charcoal on losses of N2O and NO3– concentration in the soil during mustard production. The experiment used a randomised block design with five treatments of urea...
