Biochar addition can effectively increase the soil organic carbon (SOC) content and improve soil quality. However, the formation mechanisms and structural changes of soil humic substances under biochar addition, especially under different types of biochar, are poorly understood. In this study, we compared the effects of different sources of biochar on the humus composition and humic acid (HA) stru...... hiện toàn bộ
The Effect of a Superabsorbent and Biochar on Some Physical and Hydraulic Properties of Two Arable Sandy Loam and Clay Loam SoilsJournal of Soil Science and Plant Nutrition - Tập 22 - Trang 2557-2569 - 2022

Biochar and superabsorbents are used to improve a wide range of soil properties, including water holding capacity and nutrient retention. In this research, the effect of adding biochar and a superabsorbent on some of the physical properties of two arable soil types (a sandy loam and a clay loam soil) was studied. A greenhouse experiment was performed as a completely randomized design with three re...... hiện toàn bộ
Effects of Fractionation Methods on Soil Aggregate Microbial Community Composition: Settling vs. Wet SievingJournal of Soil Science and Plant Nutrition - - Trang 1-12 - 2024
Xin Gao, Rui Wang, Yaxian Hu, Weijia Li, Lanlan Du, Shengli Guo, Shengjun Wu, Ping Huang
Soil microbial communities play a vital role in biogeochemical cycling and ecosystem functions at the aggregate scale. Soil fractionation methods can affect the interpretation of microbial spatial distribution and ecological processes in aggregates. However, there is a lack of comparative studies illustrating the differences between wet sieving and settling fractionation on soil aggregate microbia...... hiện toàn bộ
High Nitrogen Availability but Limited Potential Carbon Storage in Anaerobic Digestates from Cover CropsJournal of Soil Science and Plant Nutrition - Tập 22 - Trang 2891-2896 - 2022

Cover crops are increasingly used for biogas production, a renewable energy source, without competing for food production. The behavior of the resulting digestates after soil application is poorly understood, which prevents their efficient recycling in agriculture and the environmental assessment of their application. The objective of this study was to quantify the nitrogen availability and potent...... hiện toàn bộ
The Effects of N Addition on Soil Microbial Residues in Croplands and Forests: A Meta-analysisJournal of Soil Science and Plant Nutrition - Tập 23 - Trang 1449-1458 - 2023
Qi Chen, Xueli Ding, Bin Zhang
Nitrogen (N) availability in soil regulates microbial communities and then affects the decomposition and formation of microbial residues carbon (C), which have great impacts on soil organic carbon (SOC) sequestration. However, Asia has not yet well-assessed patterns and determinants of microbial residues C in response to N input. Here, we performed a large-scale, systematic meta-analysis of the ef...... hiện toàn bộ
The Mixture of Legumes and Gramineous as Green Manure and Its Effect on Nutrient Efficiency and Soil Solution Characteristics in Three Successive CropsJournal of Soil Science and Plant Nutrition - Tập 23 - Trang 5798-5809 - 2023
Maristela Watthier, Nain Peralta-Antonio, Maciel Carlos Soares, Ricardo Henrique Silva Santos
We determined the accumulation, agronomic efficiency (AE), and recovery efficiency (RE) of N, K, Ca, Mg, and S in the first broccoli crop, as well as the RE of N (NRE) and the soil solution (SS) characteristics in two subsequent crops, using different ratios (0, 25, 50, 75, and 100%) of Jack beans (JB) and pearl millet (PM). The treatments control, 100JB, 75JB25PM, 50JB50PM, 25JB75PM, and 100PM we...... hiện toàn bộ
