Soil CO2 Emissions as Affected by 20-Year Continuous Cropping in Mollisols
Published 2014-03-01Get full textLong-term continuous cropping of soybean (Glycine max), spring wheat (Triticum aesativum) and maize (Zea mays) is widely practiced by local farmers in northeast China. A field experiment (started in 1991) was used to investigate the differences in soil carbon dioxide (CO2) emissions under continuous...

A comprehensive analysis of the response of the fungal community structure to long-term continuous cropping in three typical upland crops
Published 2020-03-01Get full textCertain agricultural management practices are known to affect the soil microbial community structure; however, knowledge of the response of the fungal community structure to the long-term continuous cropping and rotation of soybean, maize and wheat in the same agroecosystem is limited. We assessed t...

Inversion tillage with straw incorporation affects the patterns of soil microbial co-occurrence and multi-nutrient cycling in a Hapli-Udic Cambisol
Published 2023-05-01Get full textInversion tillage with straw amendment is widely applied in northeastern China, and it can substantially increase the storage of carbon and improve multiple subsoil functions. Soil microorganisms are believed to be the key to this process, but research into their role in subsoil amelioration is limi...

Soil macroaggregates and organic-matter content regulate microbial communities and enzymatic activity in a Chinese Mollisol
Published 2019-11-01Get full textThe formation and turnover of macroaggregates are critical processes influencing the dynamics and stabilization of soil organic carbon (SOC). Soil aggregate size distribution is directly related to the makeup and activity of microbial communities. We incubated soils managed for >30 years as resto...

Integrated management of crop residue and nutrient enhances new carbon formation by regulating microbial taxa and enzymes
Published 2022-06-01Get full textAlthough returning crop residue to fields is a recommended measure for improving soil carbon (C) stocks in agroecosystems, the response of newly formed soil C (NFC) to the integrated supply of residue and nutrients and the microbial mechanisms involved in NFC are not fully understood. Therefore, an...

The efficiency of long-term straw return to sequester organic carbon in Northeast China's cropland
Published 2018-02-01Get full textBlack soil is one of the most precious soil resources on earth because it has abundant carbon stocks and a relatively high production capacity. However, decreasing organic matter after land reclamation, and the effects of long-term inputs of organic carbon have made it less fertile black soil in Nor...
