“…Recent studies examining different irrigation regimes and net types in apple cultivation establish the importance of crop water status on fruit quality (20) . Boini and others (18) , in line with Severino and others (2) , conclude that sun damage is more related to water status than to radiation. On the other hand, the use of nets, whether aiming to reduce sun damage, hail damage or for phytosanitary protection, presents adverse effects on color picking in two-tone cultivars (7) and, depending on the level of shading, it could affect floral induction and the vegetative/reproductive ratio (21) .…”

Fruit discards due to physiological disorders and mechanical damage can exceed 50% of apple production in neotropical climate zones such as Uruguay. These damages become generally visible during ripening and storage, but they depend on factors that occur in the field. Sunburn is a major quality defect in fruit, known to be related to high radiation and temperatures, and, more recently, it has also been related to the water status of tissues in fruit and trees. This study aimed to evaluate the relationship between fruit damage and fruit tissue water status in “Brasil Gala”, “Cripps Pink” and “Granny Smith”, as well as the effect of treatments to avoid sun damage (50% black net, 20% translucent white net and kaolinite application) on stemwater potential in “Granny Smith”. Fruit water potential decreased throughout the growth cycle. The exposed sides of fruits located outside the tree crown showed lower water potential than the non-exposed sides. Only the 50% black net of the sunburn avoidance treatments modified the water potential.

“…Apple sap flow studies showed that trees under a 20% shading net indeed have higher xylem water transport rates, compared to trees under a 50% shading net [13]. Another study showed improved water status for apple trees under a 50% shading net [41], compared to those without net, or even to those under a 20% shading net [42]. In these cases, trees experiencing higher incoming light may have reached, or exceeded, the "threshold" at which transpiration was higher than root water uptake.…”

Apple crop is more and more cultivated under protective netting systems. Depending on the location and sunlight intensity, apple orchards can benefit from these installations, as they will be protected against extreme weather events. Depending on the technical features of the thread, the nets will be hail-proof, wind-proof, or rain-proof, while having different shading percentages. Modern fruit production faces high pressure also related to biotic stressors; thus, modern protective nets are designed to aid pest management. These protective systems become interesting, as they will induce changes in the orchards’ microenvironment, with consequences on crop physiology. Netting mainly reduces incoming solar radiation and wind speed, altering the heat balance. Leaf gas exchanges and water relations can be positively influenced by netting in apple cultivation areas with extreme solar radiation, high temperatures, and low water availability. These considerations are important, especially if the final yield and quality are not compromised by shading. These protective systems can allow higher sustainability of apple production, lowering resource use, along with crop protection.

“…When the moisture content suddenly increases, the plants usually grow well, thereby making the vegetation more upright and resulting in a rougher image captured by the drone from above. Compared with water-deficient plants, plants with sufficient water uptake exhibit a more erect shape, and the visible-light images before and after the shading of the 3D topographic maps become rougher [61,62]. Therefore, the greater the SM content, the less visible light that eventually reaches the UAV visible light camera, thereby resulting in a smaller average pixel brightness value of the visible-light image (Figure 13).…”

Soil moisture is one of the most critical soil components for sustained plant growth and grassland management. Unmanned aerial vehicles (UAVs) are gradually replacing manual labor in various aspects of grassland management. However, their potential for monitoring soil moisture in grasslands remains largely unexplored. High vegetation coverage and frequent rainfall in the Tibetan Plateau pose a challenge for personnel working in alpine meadows. To explore the potential of UAV technology for soil moisture detection in these areas, we conducted a rainfall reduction experiment in Maqu County, China to understand the relationships among soil moisture, vegetation coverage, and visible-light images captured using UAVs. The findings indicated a significant correlation between topsoil moisture and the brightness values in visible-light images acquired by UAVs (p < 0.0001). These results demonstrated that visible-light brightness, vegetation coverage, rainfall reduction, and aboveground biomass can be utilized for estimating the topsoil moisture using these images (y = −0.2676 × Brightness + 0.2808 × Vegetation coverage −0.1862 × Rainfall reduction + 0.1357 × Aboveground biomass + 37.77). The model validation worked well (E = 0.8291, RS = −3.58%, RMA = 10.38%, RMSE = 3.5878, Pearson’s r = 0.9631, PSI = 0.0125). This study further addresses the problem of topsoil moisture measurement in flat areas of mesoscale moist alpine meadows and is expected to facilitate the widespread adoption of UAV use in grassland ecology research.
