“…On the other hand, the selection of herbaceous covers implies a risk in terms of the occurrence of pests and diseases. Furthermore, we should consider that, in some areas, the characteristics of the farms are fundamental due to their small size or the orography of the land [74]. Technology has provided solutions for the different limitations of the agricultural activity in recent decades.…”

Soil is a fundamental resource, subject to severe and quick degradation processes because of the pressure of human activities, particularly in many regions of the Mediterranean where agriculture is an important economic activity. It has been proven that the use of sustainable soil management practices can potentially give rise to the creation of a carbon sink, an increase of soil organic matter content, the maintenance of crop productivity and a reduction in erosion. Despite the existence of scientific evidence about the benefits generated by the use of sustainable practices on soil, many farmers are reluctant to adopt them. The objective of this study is to identify and give a hierarchical structure to the factors that condition the adoption of sustainable practices in the management of agricultural soil. The case of olive tree cultivation in Southeast Spain has been studied, using a participatory qualitative methodology. The results show a series of seven principal barriers (information, costs, risk aversion, characteristics of the farm and sustainable practices, macro factors, and cultural barriers) and five facilitators (technology, farmer training, awareness, incentives, and social pressure) for the adoption of the proposed sustainable agricultural practices. The principal political and legislative actions proposed to increase the adoption of sustainable agricultural practices include: administrative control, fostering environmental awareness, technical knowledge, and on-farm demonstrations; and, on the economic and financial level, incorporation of both general incentives and subsidizing specific costs. This study contributes to the development and discussion of intervention proposals that are designed to stimulate the implementation of sustainable practices in agricultural soil management.

“…And it seems likely that this trend will continue to strengthen, since the opportunities derived from the use of robotics or drones will only encourage more intense mechanization in order to maintain and increase profitability and optimise the use of natural resources and inputs that this productivist version of agriculture requires. 4 This surge in woody crops in Spain, therefore, is being based on overcoming some of the traditional characteristics presented by small farming or the generation of abundant wages, which allowed them to be considered as social crops. In all of them, a model is now imposed which implies a profound modification of the agricultural landscape.…”

The area occupied by woody crops in Spain has undergone an enormous increase in size and, more importantly, a profound green revolution that generates enormous harvest volumes that nourish the important national agro-export sector, where products such as olive oil, wine and almonds reach a notable significance. The processes of intensification follow a common pattern, which involves the occupation of the flattest and most fertile soils by firms with an ownership structure favourable for investment; the use of new varieties; and the design of denser planting patterns in which irrigation is an indispensable element and mechanization ubiquitous. The management of digitized spatial information has allowed us to map the evolution of the land uses of the olive grove, the vineyard and the almond orchard in each of the provinces where the regional specialization in these crops is greatest. This has allowed us to learn the key spatial/temporal aspects of these processes of change that are far from complete and that have led to a profound modification of agricultural landscapes, such that fragmentation and polyculture are giving way to geometry, compactness and the concentration of monoculture.

“…This area has become one of the largest areas in the world for producing rainfed organic almonds ( Prunus dulcis Mill.) (Aznar‐Sánchez et al, 2016). The selected experimental sites are located in areas with little or moderate slope (<10%) and plantation ages range between 10 and 25 years.…”

Bare soil and inadequate soil tillage are emerging problems worldwide that result in soil quality impoverishment and contribute to global warming. To reverse this situation and to improve soil structure and carbon and nitrogen storage capacity, implementing sustainable land management (SLM) practices is needed. This study evaluates the combined effect of different SLM practices (tillage with/without compost addition) and cover crop types (native/seeded cover crops) and their management (mowing or grazing) on soil organic carbon (SOC) and total nitrogen (tN) stabilization in rainfed semiarid Mediterranean almond orchards under a range of edapho‐climatic conditions. To do so, the long‐term effects of different SLM practices, such as reduced tillage plus seeded cover crops (RT + SCC), reduced tillage plus native cover crops (RT + NCC) and no tillage plus native cover crops (NT + NCC) on soil water‐stable aggregates distribution and different organic carbon and nitrogen pools were estimated at a depth of 0–20 cm (plough layer) at five experimental sites. SLM practices, implemented over 5–12 years (depending on the experimental site), were compared with the traditional tillage (TT) carried out by farmers, which consisted of three‐five passes per year to maintain soil bare. Our results demonstrate the cross‐site potential of combining reduced tillage and cover crops (regardless of seeded or native) for improving SOC and tN sequestration and stabilization. However, the magnitude of the effect of SLM practices on SOC and tN stabilization depended heavily on the local environmental and management conditions. As seeded cover crops (RT + SCC) accelerated SOC and tN stabilization compared with native cover crops (RT + NCC and NT + NCC), its implementation in these semiarid agro‐ecosystems is recommended. However, no tillage implemented as an isolated practice is not recommended in soils prone to compaction, but managed in combination with other SLM practices, such as compost addition or mulching, can be effective for SOC and tN sequestration and stabilization over time.
