Robotic solutions and technological advances for turf management demonstrated excellent results in terms of quality, energy, and time consumption. Two battery-powered autonomous mowers (2 WD and 4 WD) with random patterns were evaluated according to different trampling levels (control, low, medium, high) on a typical warm season turfgrass at the DAFE, University of Pisa, Italy. Data on the percentage of area mowed, the distance traveled, the number of passages, and the number of intersections were collected through RTK devices and processed by a custom-built software (1.8.0.0). The main quality parameters of the turfgrass were also analyzed by visual and instrumental assessments. Soil penetration resistance was measured through a digital penetrometer. The efficiency significantly decreased as the trampling level increased (from 0.29 to 0.11). The over-trampled areas were mainly detected by the edges (on average for the medium level: 18 passages for the edges vs. 14 in the central area). The trampling activity caused a reduction in turf height (from about 2.2 cm to about 1.5 cm). The energy consumption was low and varied from 0.0047 to 0.048 kWh per cutting session. Results from this trial demonstrated suitable quality for a residential turf of the Mediterranean area (NDVI values from 0.5 to 0.6), despite the over-trampling activity. Soil penetration data were low due to the reduced weight of the machines, but slightly higher for the 4 WD model (at 5 cm of depth, about 802 kPa vs. 670 kPa).

With global warming, the cultivation area of bermudagrass is moving northwards in the Mediterranean area despite its winter dormancy and loss of green color. The most common solution is overseeding with perennial ryegrass, which can be complicated to remove in spring. DLF breeders have released a new cultivar of annual ryegrass that is stress tolerant and easy to transition in spring. A trial was carried out on a sod farm in Pisa, Italy. Twenty-nine varieties of cool-season grasses, encompassing both forage and turf species, were overseeded on a hybrid bermudagrass variety ‘Tifway’ (Cynodon dactylon x transvaalensis). The aim of this trial was to compare the overseeding potential of various cool-season turfgrass species and cultivars and to identify which ones perform best in terms of cleanness of cut when overseeded on hybrid bermudagrass in autumn and maintained at a mowing height of 25 mm. Moreover, the following parameters were also assessed: actual turf height (cm); cumulated height (cm); turf visual color and quality (1–9 scale); and visual ground cover (%). Plots were managed with an autonomous mower, which adopted a daily mowing frequency and was set to work with systematic trajectories. The results showed differences between cultivars, and the annual ryegrass showed the best spring transition (scoring a mean value of 96% green cover in July 2023) compared to the other entries. The best result of CoC was measured for rough-stalked meadow grass ‘Sabrena 1’ and tall fescue ‘Turfway’ with 0.9 mm.

Turfgrass provides significant functional, environmental, recreational and aesthetic benefits; however, its high management inputs raise sustainability concerns due to intensive irrigation, fertilization and mowing. The aim of this study is to evaluate whether adopting a new mowing technology can support or enhance current low-input strategies in turfgrass management, such as reducing synthetic fertilization and deficit irrigation. This study was conducted from September 2023 to October 2024 at the Centre for Research on Turfgrass for Environment and Sports (CeRTES) in Pisa, Italy. Two turf compositions, pure tall fescue and tall fescue–microclover mixture, were managed using an autonomous mower operating daily at three mowing heights, 20, 40 and 60 mm. Turf quality, color, the NDVI, weed cover, leaf morphology, and clover presence were assessed throughout the growing season, including a drought and recovery period. The experimental design consisted of a two-factor split-plot randomized complete block design with four replications, and the statistical approach used was two-way and one-way ANOVAs with Fisher’s LSD at p = 0.05. The results of the study indicated that, under conditions where an autonomous mower was set to operate on a daily basis, the selected mowing height had minimal influence on drought response or recovery when water availability was a limiting factor. Furthermore, when subjected to the lowest mowing heights, the legume species included in the turfgrass mix demonstrated strong resilience, maintaining its presence and performance. In addition, when mowing with a high mowing frequency and at low mowing heights, the overall quality of the turfgrass appeared enhanced. These results serve as an important starting point for considering autonomous mowing technology as an innovative strategy in advancing toward turf management systems that prioritize sustainability and efficient use of resources.

High-quality playing surfaces enhance player experience and safety while serving as an appealing setting for spectators. Natural turfgrass provides optimal conditions at the beginning of the playing season but faces challenges under increasing field usage. Turfgrasses with high wear tolerance and quick recovery capacity are crucial for maintaining surface quality under intensive wear. Bermudagrass is the most used species in warm climates but needs winter overseeding in the transition zone. In Mediterranean climates, tall fescue (Schedonorus arundinaceus (Schreb.) Dumort, formerly Festuca arundinacea) has emerged as a promising species due to its tolerance to heat, drought, and salinity, alongside traits like deep rooting, shade adaptation, and wear resistance. The trial was conducted at the CeRTES experimental station in Rottaia, Pisa, Italy. Twenty-seven tall fescue cultivars and three cultivars of perennial ryegrass (Lolium perenne L.) were hand-seeded on 3 November 2022, at a rate of 43 g m⁻². The experimental design consisted of plots measuring 4.5 m² arranged in a randomized complete block design with three replications. The objective of the study is to evaluate the performance of twenty-seven cultivars of tall fescue with the aim of using the species in soccer fields with a permanent stand approach, with no need to manage spring and fall transitions. The field study encompasses determinations referring to the establishment stage, the maintenance at low cutting height stage (20 mm) and the subsequent stage of soccer use under different seasonal conditions (autumn, winter, and spring). Results showed that certain fescue cultivars, notably ‘Essential’, ‘Eyecandy’, and ‘FAG3/19-20208B’, exhibited quick establishment and adaptation to low cutting height (20 mm), and performed similarly to the reference ryegrasses ‘Gianna’ and ‘Mercitwo’ in terms of wear tolerance and recovery capacity across the three seasons. Moreover, most of the tested tall fescue cultivars performed well at a 20 mm mowing height, maintaining satisfactory quality and density. Among these, ‘Eyecandy’ and ‘Foxhound’ displayed finer leaf textures, comparable to those of the reference ryegrass.

The golf industry is undergoing a technological transformation with the integration of autonomous solutions for turf maintenance. The implementation of autonomous mowers (AMs) offers the potential for maintaining low cutting heights at high frequencies, thereby reducing soil compaction and labor requirements. In this case study conducted at Montecchia Golf Course in Italy, a comparative analysis was performed between AMs set to work with a daily mowing frequency and reel mowers set to work two times per week at 16 mm mowing height focusing on turf quality, color, normalized difference vegetation index, root growth, and soil moisture, temperature, and surface hardness. Economic and environmental evaluations, including cost analysis and local CO ₂ emissions, were also taken into account to assess the two mowing managements. Results indicate that although the reel mower exhibited superior turf quality in May, July, August, and September and turf color during all the study period (May, June, July, August, and September), AMs maintained acceptable standards while providing significant cost and environmental advantages, notably reduced CO ₂ emissions. This research supports informed decision‐making for turf managers contemplating the adoption of autonomous mowing technology.
