“…Given its consequences at the agronomic, economic, and environmental levels, the management of nitrogen fertilization has always been an important topic of scientific research [28]. Today, to optimize nitrogen fertilization at the farm level, precision farming has a strong impact on both the environment and the economy [63,70,71].…”

The European Green Deal has set a concrete strategic plan to increase farm sustainability. At the same time, the current global challenges, due to climate change and fuels and commodity market crises, combined with the COVID-19 pandemic and the ongoing war in Ukraine, affect the need for quality food and necessitate the reduction of negative external effects of agricultural production, with fair remuneration for the farmers. In response, precision agriculture has great potential to contribute to sustainable development. Precision agriculture is a farming management system that provides a holistic approach to managing the spatial and temporal crop and soil variability within a field to improve the farm’s performance and sustainability. However, farmers are still hesitant to adopt it. On these premises, the study aims to evaluate the impacts of precision agriculture technologies on farm economic, agronomic, and environmental management by farmers adopting (or not) these technologies, using the case study method. In detail, the work focuses on the period 2014–2022 for two farms that cultivate durum wheat in central Italy. The results suggest that the implementation of precision technologies can guarantee economic and agri-environmental efficiency. The results could serve as a basis for developing a program to start training in farms as well as to suggest policy strategies.

“…Our contribution to this theme was to test an automatic approach to delineate the homogeneous zones starting from multispectral images in two different sites and then agronomically validate this approach with the typical agronomic crop sampling activity and statistical analysis. The approach was able to fit with the experimental design of both sites, and statistical analysis showed differences in yields between the zone management due to the different N levels for both sites (Karpinski et al., 2015). This approach could be scaled at a large scale by using the freely accessible multispectral images obtainable by Sentinel 2 Copernicus constellation.…”

Precision agriculture (PA) is an agronomic management that allows the parsimonious use of agronomic inputs according to the crop's actual spatiotemporal needs. The most important agronomic practice of PA is the site‐specific management (SSM) of agronomic inputs. To apply SSM, the number and location of homogeneous zones must be defined. Nowadays, many approaches are used to define the number of zones in an arbitrary and constant way, such as high‐, medium‐, and low‐input zones, without a priori statistical analysis. Two combined field experiments were carried out on durum wheat (Triticum turgidum subsp. durum Desf.) in central Italy to agronomically validate an automatic approach aimed at defining the number and position of the homogeneous zones using multispectral images. For both sites, at stem elongation and anthesis, the dry biomass per square meter and Soil Plant Analysis Development (SPAD) readings were measured, while at crop maturity the yield was measured. This approach uses multispectral images as source data and uses the gap statistic index to determine the correct number of zones. The management zones created were well‐fitted with the experimental design of both sites, and the validation was made by the statistical analysis performed on yield data, SPAD, dry biomass, and normalized difference red edge index with an average difference of 40.2%, 28.5%, 57.5%, and 37.4%, respectively, between the management zones. The approach could be scaled by using the multitemporal multispectral images provided by satellite constellation, which enables farms and societies to take advantage of all the economic and environmental benefits of PA.

The aim of this paper is to show and assess how the level of data aggregation can change the way the development of organic agriculture in Poland in 2014–2021 is perceived. A composite indicator of eco-farming at different levels of territorial aggregation and in different time horizons has been built taking into account sub-components and individual indicators. The performance of organic agriculture with the initial effects of the pandemic (for 2020–2021) was also quantified. The results showed that, in populationally larger territorial units (NUTS-1, NUTS-2, NUTS-3), organic farming characteristics are less variable, whereas the same characteristics show greater variability in smaller territorial units (LAU-1, LAU-2). This reflects the strong regional character of eco-agriculture. It can be observed especially in northern and south-eastern Poland. Moreover, although the highest performance of organic farming was observed in 2021, the effects of the pandemic crisis were highly heterogeneous by location. The results may be crucial for farmers and policymakers in planning sustainable agricultural strategies and building resilient organic regions.
