“…This requires the development of indicators characterizing this system; these indicators cannot be the same ones used in conventional agriculture. Suitable indicators of conservation tillage are required (Murillo et al, 2006). In our case, AC was the only soil property that showed a significant increase in the topsoil in both trials, with a significantly greater stratification ratio under conservation tillage than under traditional tillage.…”

The results of this study showed that AC content was the most sensible and reliable indicator for assessing the impact of different soil management on soil quality in the two experiments (short-and long-term). Conservation management in dryland farming systems improved the quality of soil under our conditions, especially at the surface layers, by enhancing its storage of organic matter and its biological properties, mainly in the long-term.

“…This C pool represents a high stratification ratio under resident vegetation because the soil remained permanently undisturbed throughout the cultivation cycle; on the contrary, in BV, the stratification ratio of POC decreased due to the soil tillage when the cover crop was resown (as indicated above). With respect to the stratification ratios of WSC and PMN, Murillo et al (2006) and Madejón et al (2007Madejón et al ( , 2009) also reported significant increases of the WSC stratification ratio with no tillage under semiarid climatic conditions in Spain; a greater stratification ratio for PMN under no tillage was described by Franzluebbers (2002), and Soon et al (2007a, b). However, in later cases SOC fractions showed lower values of stratification than POC.…”

In vineyards in Spain, tillage and semiarid Mediterranean climatic conditions accelerate organic matter loss from the soil. Cover crops are a conservation management practice that can provoke changes in soil quality which requires evaluation. Stratification ratios of soil properties such as soil organic C and labile C fractions have been proposed for the assessment of soil quality under different soil management systems. Our objective was to study the effect of different cover crop management on various soil parameters and their stratification ratios. We evaluated three different soil managements in a Typic Haploxerept from NE Spain: conventional tillage (CT); 5‐y continuous cover crop of resident vegetation (RV); and 4‐y continuous cover crop of Festuca longifolia Thuill., followed by 1‐y Bromus catharticus L. after resowing (BV). We monitored soil organic C, particulate organic C, water soluble C, potentially mineralizable N, microbial biomass C, β‐glucosidase and urease enzymatic activities, and water stable aggregates at 0–2.5, 2.5–5, 5–15, 15–25, and 25–45 cm soil depths. We calculated soil depth stratification ratios of those soil properties. Resident cover crop increased microbiological properties, labile C fractions, and aggregation with respect to conventional tillage at 0–2.5 and 2.5–5 cm soil depths. However, for Bromus cover crop the same soil properties were lower than for the resident cover crop at 0–2.5 cm depth. Stratification ratios of β‐glucosidase and urease enzymatic activities, and particulate organic C showed a higher sensitivity than other soil properties; therefore, they would be the best indicators for soil quality assessment in semiarid Mediterranean vineyards.

“…Improving deep SOC content is an important part of improving soil quality. Previous study thought degree of stratification of SOC pools expressed as a ratio of soil depth could partly represent soil quality (Murillo, Moreno, Madejon, Giron, & Pelegrin, ). Thus, we must thoroughly analyze the SOC stratification ratio with different soil layers.…”

Soil organic carbon (SOC) is a core indicator of soil quality. A proper tillage system can improve SOC accumulation and benefit land restoration. This improvement is especially significant in loess soil, which is undergoing serious degradation in China. In this study, we chose a field that was used for crop production and used a traditional moldboard plow with crop residue removal (CT) for over 10 years. We then carried out a long-term field experiment (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) and changed the tillage system from a moldboard plow with crop residue removal to either a moldboard plow with buried straw system (BT), a no-tillage with straw mulch system (NT), or a subsoiling with straw mulch system (ST) to evaluate the effect of tillage system change and the effects of tillage systems on SOC storage. Tillage system change influenced SOC content, NT, ST, and BT showed higher values of SOC content and increased 8.34, 7.83, and 1.64 Mg·C·ha −1 , respectively, compared with CT. Among the 3 changed tillage systems, NT and ST showed a 12.5% and 11.6% increase in SOC content then BT, respectively. Tillage system change influenced SOC stratification ratio values, with higher value observed in BT and NT compared CT but ST. Therefore, in loess soil, changing tillage system can significantly improve SOC storage and change profile distribution. The NT and ST treatments showed a more marked SOC increase, but the increase value in stratification ratio with NT still needs attention, and our results is meaningful for soil quality improvement and land restoration.
