Special Issue Information

Dear Colleagues,

Precision Agriculture (PA) is one of the most prominent and increasing segments in the agricultural economic area. Nevertheless, most of criticalities for small companies are referred to their deficiency to access to the newest technologies. That’s why, the adoption of specific and low-cost technologies could strongly promote a sustainable and economical management of medium and small agricultural systems. The soil composition variability, microclimate and lighting conditions may differ within each Production Unit and affect vegetative vigor and the physiological parameters of plants, with direct effects on qualitative and quantitative production. It is known that the PA encompasses a wide number of methodologies that monitor different aspects of soils, plant vigor, or the vegetative–productive balance. These localized inspections allow to obtain site-specific characteristics and to program specifical approaches. In the last decade, there has been a progressive diffusion of Unmanned Aerial Systems (UAS) technologies for PA purposes, as rapid and accurate methodologies designed to evaluate the spatial variability of geometric plant parameters and plant vigor analysis by means of commercial and Open Source (OS) software. Considering the significant market increase in UAS in agricultural applications, the need for such kind of technologies in the agricultural sector could generate a great economic impact. Such tendence is evident by the reinforcement of the scientific compound focusing on topics related to UASs in precision agriculture compounds. In addition to UAS and satellite platforms, the application of different ground sensing technologies (such as spectroscopy and Unmanned Ground Vehicles (UGVs)) could reinforce the capacities to analyze and extract specific information by computing, for example, site-specific time-series analysis and low-cost Decision Support Systems (DSS).

The aim of this Special Issue is to collect papers that present innovative studies, sensors, or technologies for the improvement of PA and PF (Precision Forestry) via the use of combined Ground, Proximal and Remote sensing technologies. The integration of the above technologies in the immediate future should simplify management and promote carbon farming and agroforestry practices simultaneously. Considering the need to reduce procedural budgets and enhance the accuracy of maps, papers that use OS software and cost-effective technologies will be more than welcomed. For cost-efficient technologies data fusion can be considered by integrating different spatial, spectral, and radiometric data resolutions.

The scope of this Special Issue, regarding the combination or single use of ground, proximal and remote sensing in PA and PF, includes, but is not limited to, the following:

  • Soil digital mapping;    
  • Canopy condition assessment;
  • Canopy architecture computation;
  • Missing plants detection;
  • Biophysical plant parameters;
  • Spatio-temporal analysis;
  • Geostatistics of ground sensing;
  • Decision support system;
  • Carbon farming.

Article types: research articles, review papers, communication papers, and technical notes.

Accurately measuring leaf chlorophyll content (LCC) is crucial for monitoring maize growth. This study aims to rapidly and non-destructively estimate the maize LCC during four critical growth stages and investigate the ability of phenological parameters (PPs) to estimate the LCC. First, four spectra were obtained by spectral denoising followed by spectral transformation. Next, sensitive bands (Rλ), spectral indices (SIs), and PPs were extracted from all four spectra at each growth stage. Then, univariate models were constructed to determine their potential for independent LCC estimation. The multivariate regression models for the LCC (LCC-MR) were built based on SIs, SIs + Rλ, and SIs + Rλ + PPs after feature variable selection. The results indicate that our machine-learning-based LCC-MR models demonstrated high overall accuracy. Notably, 83.33% and 58.33% of these models showed improved accuracy when the Rλ and PPs were successively introduced to the SIs. Additionally, the model accuracies of the milk-ripe and tasseling stages outperformed those of the flare–opening and jointing stages under identical conditions. The optimal model was created using XGBoost, incorporating the SI, Rλ, and PP variables at the R3 stage. These findings will provide guidance and support for maize growth monitoring and management.
