Abstract
The tree growth modeling has been a major concern in horticulture to delineate areas of varying development within the orchard.
In this study, a spatio-temporal resolved analysis of trees was conducted in an apple orchard (Malus × domestica ‘Gala’). The apparent soil electrical conductivity (ECa) was measured and a light detection and ranging (LiDAR) 2D terrestrial laser scanning system was used for estimating the canopy (n=1109) volume (VLiDAR). The LiDAR system was used to monitor the whole field repeatedly over the growth season.
The VLiDAR related negatively with ECa in low (r=-0.55), mid (r=-0.45), and high (r=-0.58) areas.
The tree growth in low ECa was approximately 30% enhanced compared to mid and high ECa areas.
These results suggest that the canopy growth varies spatially, whereas the terrestrial laser scanning offers a feasible method for implementation in decision support systems in horticulture.
