Special Issue Information

Dear Colleagues,

Olives constitute a significant crop in the Mediterranean basin. Due to its characteristics, this crop is not very demanding in terms of requiring fertile and deep soils, and it is well adapted to the Mediterranean climate. Most plantations are rainfed and usually are established in poor soils on hills. This, combined with an improper soil management strategy that leaves large areas of bare soil, causes the degradation of aggregate stability and increases  erosion, depleting soil organic matter, nutrients and general biodiversity when high-intensity rainfall events occur.

Solutions for conserving the soil and improving its health are needed to attain olive orchard sustainability. Soil status can be improved through the use of management practices that conserve the soil, increase organic matter, and improve fertility. Likewise, recycling natural resources must be considered in order to foster a circular economy in the olive orchard.

To achieve a sustainable olive sector, three dimensions of sustainability should be considered: environmental, economic and social. In the Mediterranean area, many localities depend on the olive sector economically and socially. Thus, sustainability improvements will benefit all realms of social life.

Furthermore, sustainable practices should provide other ecosystem services, such as climate change mitigation, biodiversity improvement, water quality and the maintenance of soil fertility.

The focus of this Special Issue will be to bring together advances towards applications of sustainable practices in olive orchards. We welcome the submission of novel research, reviews, and opinion pieces on related topics.

Carbon farming practices are pivotal for enhancing soil organic carbon (SOC) storage in agricultural systems. This study focuses on evaluating the effects of spontaneous cover crops as a conservation strategy compared to conventional management practices on total, non-protected, and protected SOC fractions, as well as carbon saturation, in olive groves across 13 paired sites (26 sites in total) in Andalucía, Spain. The research evaluates organic carbon concentrations in different soil fractions: non-protected (250–2000 µm), physically protected (53–250 µm), and chemically protected (<53 µm). The results reveal that olive groves managed with temporary spontaneous cover crops (CC) over the last 8–12 years generally exhibit higher SOC concentrations compared to those managed conventionally (BS), with significant differences observed across multiple sites. CC sites exhibited higher carbon stocks, with protected carbon averaging 42.6 Mg C ha−1 compared to 29.7 Mg C ha−1 in BS, and non-protected carbon at 10.3 Mg C ha−1 versus 4.8 Mg C ha−1. A direct relationship was identified between total SOC and both protected and non-protected carbon fractions, indicating that the soil of the studies olive orchards is far from being saturated in protected SOC. Moreover, the soil of the CC olive farms had a lower carbon saturation deficit (45.3%) compared to BS (67.2%). The findings show that maintaining the cover crops in olive orchards significantly contributed to carbon sequestration and reduced carbon saturation deficits by increasing the stocks of protected SOC.

Soil management in orchards can have several economic and environmental implications. In this study, three different soil management systems were compared in a dry-farmed olive grove: conventional tillage (tillage), glyphosate-based herbicide (herbicide) and sheep grazing. The experiment lasted eleven years (2011–2022) and was carried out after a previous trial conducted on the same plot with the same treatments and duration (2001–2011). However, in the earlier trial, the herbicide and sheep grazing treatments switched positions in the plot, while the tillage treatment remained in its original place. The average total accumulated olive yields between 2011 and 2022 were 225.1, 230.9, and 245.0 kg tree−1 for the sheep grazing, tillage, and herbicide treatments, respectively. However, no significant differences were observed between the treatments. The levels of total organic carbon in the soil, measured in samples collected in the last year of the study, were 41.3, 33.7, and 37.3 g kg−1, respectively, for the same treatments. These findings indicated that the tillage treatment exhibited lower soil organic matter content and reduced bioavailability of some nutrients, which raises concerns about its sustainability. On the contrary, employing sheep grazing with an appropriate stocking rate, effectively controlling vegetation in the spring, ensured favourable soil properties and olive yields comparable to the other treatments. Moreover, the sheep grazing approach provides supplementary advantages to the farmer, including revenue from the sale of animal products and the opportunity to transition to organic farming systems, which better align with the preferences of contemporary societies.
