“…The CEC was high, ranging from 12.45 cmol kg −1 to 30.66 cmol kg −1 (limit proposed by Hazelton andMurphy, 2007 based on Metson, 1961). In this line, Ruiz et al (2012) in Mediterranean rangelands obtained similar results, while Pulido-Fernández et al (2013) in Iberian open woodland rangelands obtained low CEC values caused by nutrient scarcity. SOC content was generally low in all the studied soils, although the SOC decrease with depth was much more intense in CT soils.…”

Abstract. Soil organic carbon (SOC) concentration is a soil variable subject to changes. The management system is a key factor that influences these changes. To determine the long-term effects of the management system on SOC stocks (SOCS) in olive groves, 114 soil profiles were studied in the Los Pedroches Valley (Mediterranean rangelands -southern Spain) for 20 years. The management practices were conventional tillage (CT) and organic farming (OF) in four soil types: Cambisols (CMs), Regosols (RGs), Luvisols (LVs) and Leptosols (LPs). Soil properties were statistically analysed by management techniques, soil types and horizons. Significant differences (p < 0.05) were found between soil types and management practices. It was equally observed that the management system affected SOCS. In addition, the total SOCS during the 20-year experiment increased in OF with respect to CT by 72 and 66 % in CMs and LVs respectively. SOC showed significant differences for horizons (p < 0.05) in relation to the management type. The stratification ratio (SR) was used as an indicator of soil quality based on the influence of surface SOC levels on erosion control, water infiltration and nutrient conservation with respect to deep layers. The SR of SOC from the surface to depth was greater in CT compared to OF with the exception of RGs. In all cases, the SR of SOC was > 2. These results indicate high soil quality and that management practices affect SOC storage in the Los Pedroches Valley.

“…The restoration and management of the tree and shrub layers in these systems will also have a substantial effect on soils. Studies focusing on soil carbon stock distribution (Howlett et al, 2011a,b;Simón et al, 2013), land management (Pulido-Fernández et al, 2013;Seddaiu et al, 2013, López-Díaz et al, 2017, fine root distribution (Moreno et al, 2005) or shrub biomass (Castro & Freitas, 2009;Ruiz-Peinado et al, 2013b) could help forest managers to maximize carbon sequestration, avoid degradation and guarantee sustainability.…”

Forest management and carbon sequestration in the Mediterranean region: A review

et al. 2017

Aim of study: TTo review and acknowledge the value of carbon sequestration by forest management in the Mediterranean area. Material and methods:We review the main effects of forest management by comparing the effects of silvicultural systems (even-aged vs. uneven-aged stands, coppice systems, agroforestry systems), silvicultural options (thinning, rotation period, species composition), afforestation, harvesting, fire impact or effects of shrub layer on carbon sequestration in the Mediterranean area.Main results: We illustrate as forest management can clearly improve forest carbon sequestration amounts. We conclude that forest management is an effective way to maintain and enhance high carbon sequestration rates in order to cope with climate change and provision of ecosystem services. We also think that although much effort has been put into this topic research, there are still certain gaps that must be dealt with to increase our scientific knowledge and in turn transfer this knowledge to forest practitioners in order to achieve sustainable management aimed at mitigating climate change.Research highlights: It is important to underline the importance of forests in the carbon cycle as this role can be enhanced by forest managers through sustainable forest management. The effects of different management options or disturbances can be critical as regards mitigating climate change. Understanding the effects of forest management is even more important in the Mediterranean area, given that the current high climatic variability together with historical human exploitation and disturbance events make this area more vulnerable to the effects of climate change.Additional keywords: global carbon cycle; forest sink; forest mitigation strategies; carbon sequestration potential; climate change mitigation; Mediterranean forests.

Short-term grazing exclusion has no impact on soil properties and nutrients of degraded alpine grassland in Tibet, China

et al. 2015

Abstract. Since the 1980s, alpine grasslands have been seriously degraded on the Tibetan Plateau. Grazing exclusion by fencing has been widely adopted to restore degraded grasslands. To clarify the effect of grazing exclusion on soil quality, we investigated soil properties and nutrients by comparing free-grazing (FG) and grazing exclusion (GE) grasslands in Tibet. Soil properties -including soil bulk density, pH, particle size distributions, and proportion of aggregatesshowed no significant difference between FG and GE plots.
