“…A meta-data analysis study found that organic agriculture can increase MBC by as much as 32% over conventional practices (33). The higher MBC under organic system was likely associated with the increased organic matter inputs (34). The application of organic matter also adds microbes because compost is rich in the microbial population (1).…”

The effects of organic and conventional production systems on crop productivity have been greatly explored, but their effects on soil microbial processes were often neglected. A comparative field study of organic and conventional production systems was conducted at the Tennessee State University research farm to determine soil heterotrophic respiration and microbial biomass carbon. Leafy green vegetables were grown in a conventional production system in an open field, and they were grown in an organic production system, using three different row covers (agribon cloth, insect net, and plastic), and in an open field. Soil samples (0-15cm) were collected from the two production systems. Soil heterotrophic respiration rate (RH), microbial biomass carbon (MBC), and biomass-specific heterotrophic respiration rate (the inverse is used as a proxy for microbial carbon use efficiency) were quantified. The results showed that the conventional production system significantly increased RH relative to the organic system. Organic production system, however, significantly enhanced MBC and reduced biomass-specific respiration rate indicating an increase in carbon use efficiency. Although MBC remained unchanged among the row covers, insect net increased RH and biomass-specific heterotrophic respiration rate. Our results suggest that the organic production system not only promoted soil microbial abundance but also limited soil heterotrophic respiration to the atmosphere governed by the elevated carbon use efficiency.

“…In particular, they have been increasingly used to investigate changes in functions due to anthropogenic impacts (Dick, 1984;Vepsäläinen et al, 2001;Naseby and Lynch, 2002;Lagomarsino et al, 2008). The effectiveness of alternative vineyard strategies on higher enzyme hydrolytic activities has been demonstrated in several experiments applying green manure (Okur et al, 2009), notillage (Lagomarsino et al, 2008), grass-covering (Schreck et al, 2012), compost made from the organic fraction of municipal solid waste (Calleja-Cervantes et al, 2015), and biochar-compost mix (Mackie et al, 2015). The most extensively studied group of enzymes with ecological importance in soil are hydrolases, which are involved in the main biogeochemical cycling of elements and release of carbon, nitrogen, phosphorus and sulfur compounds (Caldwell, 2005).…”

“…Organic amendments such as manure and compost provide a direct source of carbon for soil organisms and an indirect carbon source via increased plant growth and plant residue returns (Bünemann et al, 2006). For example, in Turkish vineyards, the application of green manure resulted in greater enzyme activity, and microbial biomass and activity (Okur et al, 2009). Compost applications or mulching were shown to have positive effects on soil structure comparable to permanent grass cover (Nachtergaele et al, 1998;Pinamonti, 1998).…”

Vineyard Management and Its Impacts on Soil Biodiversity, Functions, and Ecosystem Services

Healthy soils form the basis of sustainable viticulture, where soil characteristics have a direct impact on wine quantity and quality. Soil not only provides water and nutrients to vines, but is also a living medium containing micro- and macroorganisms that perform many ecological functions and provide ecosystem services. These organisms are involved in many processes, from decomposing organic matter to providing minerals to vine roots. They also control diseases, pests, and weeds, in addition to improving the soil structure in terms of its capacity to retain water and nutrients. Related to decomposition processes, the carbon content of vineyard soils influences fertility, erosion and biogeochemical cycles, with significant implications for the global climate. However, common agricultural practices represent strong threats to biodiversity and associated ecosystem services provided by vineyard soils. As consumers increasingly consider environmental aspects in their purchase decisions, winegrowers have to adapt their vineyard management strategies, raising the demand for sustainable pest- and weed-control methods. This article presents a comprehensive review of the impacts of vineyard practices on the soil ecosystem, biodiversity, and biodiversity-based ecosystem services, and provides future prospects for sustainable viticulture.

“…However, to our knowledge, very little data are available beyond 30 cm soil depth. For the vineyard, we only identified five references of studies concerning Arenosols in Mediterranean climatic conditions (Conradie, 2001;Fourie et al, 2005;López-Piñeiro, 2013;Nogales et al, 2019;Okur et al, 2009). The Brugassières Arenosol was found to be among the soils with the lowest organic carbon content values (Fig.…”

“…Soils in a Mediterranean climatic condition that have inherited a long history of viticulture are representative of situations where land use is likely to have affected C dynamics in a very significant way, since vineyards are among the most degraded agricultural crop systems (Giagnoni et al, 2019;Panagos et al, 2015). Nevertheless, SOC studies in vineyards have received less attention as compared to arable and pasture systems (Payen et al, 2021), while viticulture is now a major agricultural growth sector under Mediterranean climatic conditions worldwide (Eldon and Gershenson, 2015).…”

Abstract. Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7 % of the world's soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions). As for other soil types, land use changes (from forest or grassland to cropland) lead to a loss of substantial soil organic carbon (SOC) stocks and have a lasting impact on the SOC turnover. Here we quantified long-term variations in carbon stocks and their dynamics in a 80 cm deep Mediterranean Arenosol that had undergone a forest-to-vineyard land use change over a 100 years ago. Paired sites of adjacent plots combined with carbon and nitrogen quantification and natural radiocarbon (14C) abundance analyses revealed a C stock of 53 t ha−1 in the 0–30 cm forest soil horizon, which was reduced to 3 t ha−1 after long-term grape cultivation. Total organic carbon in the vineyard was dramatically low, with around 1 g C kg−1, and there was no vertical gradient as a function of depth. 14C showed that deep plowing (50 cm) in the vineyard plot redistributed the remaining carbon both vertically and horizontally. This remaining carbon was old (compared to that of the forest), which had a C:N ratio characteristic of microbial organic matter and was probably stabilized within organomineral associations. Despite the drastic degradation of the organic matter (OM) pool in this Arenosol, this soil would have a high carbon storage potential if agricultural practices, such as grassing or organic amendment applications, were to be implemented within the framework of the 4 per 1000 initiative.
