Special Issue Information

Dear Colleagues,

With a growing global population, sustainable agriculture becomes more and more important. While dealing with climate variability and change, how to produce more food of higher quality with limited resources is a great challenge. Therefore, information on the ecological and physiological (Ecophysiological) status of crops would be essential for crop growth diagnostics and yield prediction.

In this context, to fulfill these demands, there have been significant improvements in assessing plant Ecophysiology technologies. The developments in remote sensing, such as using ground-based, airborne, and satellite platforms, are providing new insight and capabilities for understanding vegetation and ecosystem properties, dynamics, and functional processes. Meanwhile, global observations span multiple spectral ranges (visible, near-infrared, thermal, microwave, etc.), enabling more precise documentation and a new understanding of vegetation changes and their environmental controls.

In this Special Issue on “Remote Sensing in Ecophysiological and Agricultural Applications”, we welcome topics that include, but are not limited to, the following:

  • Precision agriculture
  • UAV spectral sampling
  • Vegetation phenology and stress
  • Satellite environmental data
  • Plant–climate interactions
  • Plant Ecophysiology
  • Crop growth monitoring
  • Crop production and environmental quality
  • Vegetation indices and other spectral transformations

In response to significant shifts in dietary and lifestyle preferences, the global demand for fruits has increased dramatically, especially for apples, which are consumed worldwide. Growing apple orchards of more productive and higher quality with limited land resources is the way forward. Precise planting age identification and yield prediction are indispensable for the apple market in terms of sustainable supply, price regulation, and planting management. The planting age of apple trees significantly determines productivity, quality, and yield. Therefore, we integrated the time-series spectral endmember and logistic growth model (LGM) to accurately identify the planting age of apple orchard, and we conducted planting age-driven yield prediction using a neural network model. Firstly, we fitted the time-series spectral endmember of green photosynthetic vegetation (GV) with the LGM. By using the four-points method, the environmental carrying capacity (ECC) in the LGM was available, which serves as a crucial parameter to determine the planting age. Secondly, we combined annual planting age with historical apple yield to train the back propagation (BP) neural network model and obtained the predicted apple yields for 12 counties. The results show that the LGM method can accurately estimate the orchard planting age, with Mean Absolute Error (MAE) being 1.76 and the Root Mean Square Error (RMSE) being 2.24. The strong correlation between orchard planting age and apple yield was proved. The results of planting age-driven yield prediction have high accuracy, with the MAE up to 2.95% and the RMSE up to 3.71%. This study provides a novel method to accurately estimate apple orchard planting age and yields, which can support policy formulation and orchard planning in the future. Full article
