Special Issue Information

Dear Colleagues,

Soil is the collection of natural bodies on the earth’s surface that supports plant life, and the foundation of food security and the cornerstone of biological health. With the excessive utilization of soil resources by human beings, soil degradation such as soil compaction, barrier layer, imbalance of nutrient ratio, salinization, and soil contamination appear, causing soil function degradation, restricting food production, and threatening food security. Efficient, safe, and healthy soil management is an important measure to realize the sustainable development of the whole social economy, environment, and human health. How to improve soil health levels, especially agricultural soil systems through soil resource management; how to make food production safer and more sufficient; and how to ensure the sustainable development of a healthy planet—these are all urgent challenges that need to be solved by soil science researchers. It is necessary to first analyze the soil formation factors and evolution mechanism of soil resources in an area and clarify the soil evolution rate, degradation, and restrictive mechanism.

Therefore, this Special Issue will collect new developments and methodologies, best practices, and applications related to the science of soil evolution, management, and sustainable utilization, especially in agricultural soil systems. We welcome submissions that provide the community with the most recent advancements in all aspects of soil, crop, agriculture, management, and life, including but not limited to the following:

  • Soil biodiversity;
  • Soil evolution;
  • Spatial and temporal changes in soil organic carbon, nitrogen, phosphorus, heavy metals, salinity, and others in representative areas;
  • The relationships between soil properties and human activities;
  • Inversion of soil properties from single and/or multisource sensor-based data (e.g., multispectral, hyperspectral, thermal, LiDAR, SAR, gas, radioactivity sensors);
  • Emerging approaches to characterizing properties and greenhouse gas emissions;
  • Earth's critical zone;
  • Soil modeling;
  • Digital soil mapping;
  • Soil health evaluation;
  • Climate change and soils;
  • Cultivated soil management;
  • Soils for sustainable agriculture;
  • Intelligent agriculture.

Pingliang City has a complex topography and diverse soil types. To realize the improvement of soil according to local conditions and the reasonable and sustainable use of soil resources, an evaluation of soil quality in Pingliang City was carried out, based on the soil distribution situation in Pingliang City, adopting a method combining fuzzy mathematics and cluster analysis of the main evaluation factors, such as soil organic matter, topsoil depth, soil erosion intensity, soil moisture regime, effective soil thickness, soil texture, soil profile structure, soil nutrient status and topographical parts, to carry out a comprehensive evaluation. A comprehensive evaluation of soil quality was conducted in seven counties under the jurisdiction of Pingliang City, and the evaluation results were compared and analyzed against the national standard, “Cultivated land quality grade”, to provide a basis for the selection of scientific soil improvement methods. The results of the arable land quality grades indicate that the quality of farmland in Pingliang City is divided into three to ten grades, and the average quality grade of farmland is 6.83, which is in the middle–lower level, and the overall grade distribution shows the characteristics of low in the middle and high in the east and west. The results of fuzzy mathematics combined with cluster analysis indicated the following trends in soil quality for the 12 soil genera: Chuan black gunny soil > yellow moist soil > sandy soil > silt soil > mulching helilu soil> loessal soil> loamy soil > slope loessal soil > arenosol > tillage leaching gray cinnamon soil > calcareous gray cinnamon soil > red clay soil. The results of the combination of fuzzy mathematics and clustering were significantly correlated with the results of the evaluation of the soil quality of arable land; the correlation coefficient was 0.884. This indicates that the method can accurately and objectively review the advantages and disadvantages of arable land soil and can be effectively applied to the evaluation of the soil quality of agricultural soils in other regions. It is a complement to the existing evaluation of the soil quality of arable land and at the same time provides a reference for the improvement of soil quality in agricultural regions. Full article

The evaluation of soil particle composition and salt dynamics is essential for promoting the sustainable development of oasis agriculture in arid regions under long-term mulched drip irrigation (MDI). In this study, we employed the space-for-time substitution method to investigate the long-term effects of MDI on soil particle composition and salinity. Additionally, seven fields, with MDI durations ranging from 0 to 16 years, were selected to represent the primary successional sequence though time in Northwest China. Soil samples were collected from three soil depths (0–30 cm, 30–60 cm, and 60–100 cm) and then analyzed in the laboratory for soil particle composition and salt content. Our findings demonstrated that influenced by the depth of mechanical cultivation and the maximum wetting front depth, the long-term application of MDI significantly altered both the structure of soil layers and the composition of soil particles after 8 years. Soil sand content and soil salinity gradually decreased, whereas the content of soil silt and clay increased with increasing MDI duration throughout 0–100 cm soil depth. Furthermore, the rates of soil desalination stabilized after 10 years of MDI application, with desalination levels exceeding 90% in the 0–100 cm soil layer. Additionally, the soil mass fractal dimension (Dm) exhibited an upward trend across 0–100 cm soil depth. The changes in soil particle composition indirectly influenced the variations in Dm and salt content. Our study demonstrated that long-term application of MDI effectively mitigated soil salinity, changed soil structure, and ultimately enhanced soil quality and cotton yield. Full article
