Special Issue Information

Dear Colleagues,

Soil moisture plays a key role in the distribution of water, energy, and carbon interactions between the land and atmosphere system. Detailed information on soil moisture is essential for water resources and natural hazard risk assessment, management, and understanding of ecosystem dynamics, among others.

Soil moisture hotspots that emerge from this spatial variability have significant implications for the scientific understanding and prediction of many hydrological processes and applications. For example, soil moisture hotspots influence freshwater sources and the water footprint, as wet and dry conditions require different irrigation and fertilizer interventions. However, soil moisture varies strongly in space, from a few centimeters to several kilometers depending on the basin scale.

Soil moisture spatial variability leads to changes in land surface temperature and the evapotranspiration process altering drought impacts controlling cloud formation and the development of convective storms. Soil moisture hotspots can modify runoff generation, resulting in faster flood events and landslides. The analysis of soil moisture spatial variability and the effects on the water cycle will be covered in this Special Issue.

Although significant progress has been made in recent decades, the study of this key variable of the water cycle is still important if, for example, the gaps in subsurface soil moisture calculation and the coarse spatial resolution of soil moisture satellite missions are considered.

Articles may address, but are not limited to, the following topics:

  • Signatures of large-scale soil moisture dynamics on basins and at the local scale.
  • Instrumentation–installation–temporal resolution errors.
  • Machine learning for soil moisture assessment.
  • Soil moisture monitoring by implementing satellite (polar and geostationary) data.
  • Soil moisture estimation using the gravimetric technique.
  • Impact of soil moisture on the global economy.
  • Soil moisture and expectations regarding future climate.
  • Significance of soil moisture in the economics of climate change impacts and adaptation on hydrological basins or the economy within soil moisture.
  • Soil moisture dynamics in agriculture.
  • Application of remote sensing to estimate soil moisture.
  • Spatial and temporal analysis of soil moisture patterns.
  • Effect of soil organic matter contents on moisture supply capacities.
  • Dynamics of soil moisture balance components.
  • Relationship between soil moisture and the productivity of natural vegetation.
  • Role of soil moisture sensors in smart irrigation.
  • Soil moisture sensors and precision agriculture.
  • Evaluation of soil moisture anomalies.
  • Geophysical measuring in dry and wet soil conditions.
  • Assessing surface and root zone soil moisture for agricultural purposes.

Agricultural productivity is significantly influenced by the restricted availability of irrigation water and poor soil health. To assess the influence of different potential soil moisture deficit (PSMD) regimes and integrated nutrient levels on the growth, yield, and quality of wheat, an experiment was carried out at the research area of the University of Agriculture, Faisalabad. The experiment includes three levels of PSMD (I1: 25 mm PSMD, I2: 50 mm PSMD, and I3: 75 mm PSMD) and four integrated nutrition levels (N1: 50% organic manure + 50% Inorganic NPK, N2: 75% organic manure + 25% inorganic NPK, N3: 100% application of organic manure, and N4: 100% application of inorganic NPK). Results of the experiment revealed that maximum grain yield (4.78 t ha−1) was obtained as a result of irrigation at 50 mm PSMD with the combined use of organic and inorganic sources in equal proportions. In contrast, the minimum yield was observed at I3: 75 mm PSMD with 100% application of organic manure. The highest plant height (99.11 cm), fertile tillers (284.4), 1000-grain weight (44.48 g), biological yield (14.82 t ha−1), radiation use efficiency for grain yield (RUEGY) (5.71 g MJ−1), and radiation use efficiency for total dry matter (RUETDM) (2.15 g MJ−1) were observed under N1: 50% organic manure with 50% inorganic NPK treatment. The highest value of these parameters was also observed in I2 (50 mm PSMD). The results of this study can be extended to arid and semi-arid regions, where deficit irrigation is a key strategy to address water crises and to meet sustainable development goals. Full article
