“…Because this method yields, on average, 75% of the total OC, the results of the analysis were divided by 0.75 to obtain the total OC content (De Leenheer and Van Hove, 1958). The fully dispersed particle-size analysis was obtained using the sieve pipette method (De Leenheer, 1966). The minimally dispersed particle-size distribution was obtained in a similar way without chemically dispersing the samples.…”

Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments. These experiments showed that rill and interrill erosion processes have contrasting impacts on enrichment of OC in transported sediment. Rill erosion was found to be nonselective, while for interrill erosion the enrichment ratio of OC, EROC, varied between 0.9 and 2.6 and was inversely related to the unit sediment discharge. At unit sediment discharge values >0.0017 kg s−1 m−1, the EROC remained equal to 1. The enrichment process was not influenced by raindrop impact. Enrichment of OC by “aggregate stripping” was found to be unimportant in our study. This was attributed to the low aggregate stability of the soil and the equal distribution of OC within the different soil aggregate classes.

“…Soil structure and organic matter evaluated through organic C and total N were reported as useful variables to assess soil quality (Gregorich et al, 1994;Doran and Parkin, 1994). Soil aggregation was determined according to the method of De Leenheer and De Boodt (1958). Soil samples were dry and wet sieved, and the variation between dry and wet average aggregate diameter ( AAD) after sieving, which is indicative of structural stability, was used for analysis.…”

“…Abstracts and full texts of these studies were reviewed for relevance and inclusion in the dataset (see Figure S1 in Supplementary information). Publications had to meet the following criteria: Studies were performed in central‐eastern Argentina (Pampa region). Studies had at least three independent replicates at one or more sites. Experiments were conducted in the field or at a research station. Studies reported comparisons between a more intensified sequence or treatment and a less intensified sequence or control. Studies were reported in peer‐reviewed journal articles, conference collections, theses or dissertations. Studies reported at least one of the following variables: aggregate stability determined by using Le Bissonnais (1996) or De Leenheer and De Boodt (1958) methods and/or soil organic carbon content, using an elemental carbon analyzer or the Walkley and Black (1934) method. Studies identified experiment duration, sampling depth of soil properties, soil management, soil texture and cover crop species. Control and treatment differed in intensification of the crop sequence, keeping all other management factors similar (grain crop, varieties, fertilization, tillage, etc. ). Of the experiments in which measurements were taken at different times, we considered only the contrasts that had different ICS levels (ICS index). The crop sequences lasted for at least 1 year. …”

Intensification of crop sequence (ICS) has been proposed as a key field practice to preserve soil health and achieve more sustainable agricultural systems. However, the effects of ICS are site‐specific and vary according to soil characteristics, climatic conditions, the duration of the crop sequencing and the types of crop involved. Soil aggregate stability (AS) and soil organic carbon (SOC) stock are useful indicators of soil health as they are closely linked to diverse soil services and functions and are sensitive to management practices. We performed a meta‐analysis of 33 studies to analyse the impact of ICS on SOC stock and AS in field experiments in the central‐eastern region of Argentina. Our results showed that ICS increased SOC stock and AS, with an overall mean change of 7% and 22%, respectively. Fine‐textured soils showed the greatest SOC stock increase (12%), comparable to the increase observed in coarse‐textured soils (11%); in medium‐textured soils this increase was less than half (5%). Coarse‐textured soils had the greatest increase in AS (32%), followed by medium‐textured and fine‐textured soils, which also showed notable improvements (25% and 19%, respectively). Greater diversity of crops resulted in larger increases in both AS and SOC. ICS generated a larger increase of SOC stock in the soil surface (0–10 cm) than in the subsurface (10–20 cm), whereas the opposite was found for AS. Long‐term studies (≥9 years) had the greatest effect on AS and SOC stock. Regression analysis revealed that the initial carbon stock influenced SOC stock results following ICS, increases being greater when initial carbon stock contents were smaller. Introducing gramineous species into the crop sequence was associated with a greater improvement of AS and SOC stock. Finally, the mean rate of carbon sequestration from ICS in all the studies amounted to 0.28 Mg ha−1 yr−1. Overall, ICS is a useful strategy for improving SOC storage and AS in this region, though results may vary according to soil characteristics and management practices.
