Special Issue Information

Dear Colleagues,

In recent years, the integration of remote sensing technologies with agricultural practices has ushered in a new era of precision farming and soil management. The capacity to acquire high-resolution data from satellites, UAVs, and other airborne platforms has profoundly transformed the methodologies by which farmers monitor crop growth and assess soil condition. Accurate and timely information on crop growth and soil conditions is essential to precision farming and sustainable agricultural production. Precise and timely insights into crop growth and soil conditions are indispensable for facilitating precision farming and fostering sustainable agricultural production. This Special Issue aims to illuminate the latest advancements in remote sensing techniques and their applications in enhancing crop productivity and monitoring soil conditions directly related to crop growth.

We welcome contributions that delve into various aspects of remote sensing in agriculture, focusing particularly on crop growth monitoring and soil conditions crucial for crop growth. These include, but are not limited to, the following:

  • Utilization of satellite and aerial remote sensing techniques for continuous monitoring of crop development and estimation of yield.
  • Exploration of hyperspectral and multispectral imaging for early detection of crop diseases, nutrient deficiencies, and stress conditions.
  • Utilizing remote sensing enables precise and cost-effective data collection in agricultural fields, facilitating spatial analysis of crop growth patterns and soil variability.
  • Implementation of machine learning and artificial intelligence algorithms to analyze remote sensing data for prediction modeling in different farming practices.
  • Development of innovative models for real-time monitoring of soil moisture, salinity, nutrient content, and other essential soil parameters directly impacting crop health and productivity.
  • Integration of remote sensing data with agricultural models for improved crop management.

Monitoring winter wheat Soil–Plant Analysis Development (SPAD) values using Unmanned Aerial Vehicles (UAVs) is an effective and non-destructive method. However, predicting SPAD values during the booting stage is less accurate than other growth stages. Existing research on UAV-based SPAD value prediction has mainly focused on low-altitude flights of 10–30 m, neglecting the potential benefits of higher-altitude flights. The study evaluates predictions of winter wheat SPAD values during the booting stage using Vegetation Indices (VIs) from UAV images at five different altitudes (i.e., 20, 40, 60, 80, 100, and 120 m, respectively, using a DJI P4-Multispectral UAV as an example, with a resolution from 1.06 to 6.35 cm/pixel). Additionally, we compare the predictive performance using various predictor variables (VIs, Texture Indices (TIs), Discrete Wavelet Transform (DWT)) individually and in combination. Four machine learning algorithms (Ridge, Random Forest, Support Vector Regression, and Back Propagation Neural Network) are employed. The results demonstrate a comparable prediction performance between using UAV images at 120 m (with a resolution of 6.35 cm/pixel) and using the images at 20 m (with a resolution of 1.06 cm/pixel). This finding significantly improves the efficiency of UAV monitoring since flying UAVs at higher altitudes results in greater coverage, thus reducing the time needed for scouting when using the same heading overlap and side overlap rates. The overall trend in prediction accuracy is as follows: VIs + TIs + DWT > VIs + TIs > VIs + DWT > TIs + DWT > TIs > VIs > DWT. The VIs + TIs + DWT set obtains frequency information (DWT), compensating for the limitations of the VIs + TIs set. This study enhances the effectiveness of using UAVs in agricultural research and practices. Full article
