We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as 'promising practices'; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or 'standard practice' (baseline). Relative effects were analysed through indicator response ratio (RR) under each paired practice. For this we considered data of 30 long-term experiments collected from 13 case study sites in Europe and China as collated in the framework of the EU-China funded iSQAPER project. These were complemented with data from 42 long-term experiments across China and 402 observations of long-term trials published in the literature. Out of these, we only considered experiments covering at least five years. The results show that OM addition favourably affected all the indicators under consideration. The most favourable effect was reported on earthworm numbers, followed by yield, SOM content and soil aggregate stability. For pH, effects depended on soil type; OM input favourably affected the pH of acidic soils, whereas no clear trend was observed under NT. NT generally led to increased aggregate stability and greater SOM content in upper soil horizons. However, the magnitude of the relative effects varied, e.g. with soil texture. No-tillage practices enhanced earthworm populations, but not where herbicides or pesticides were applied to combat weeds and pests. Overall, in this review, yield slightly decreased under NT. Crop rotation had a positive effect on SOM content and yield; rotation with ley very positively influenced earthworms' numbers. Overall, crop rotation had little impact on soil pH and aggregate stability \u2212 depending on the type of intercrop; alternatively, rotation of arable crops only resulted in adverse effects. A clear positive trend was observed for earthworm abundance under organic agriculture. Further, organic agriculture generally resulted in increased aggregate stability and greater SOM content.

Sin embargo, muchos estudios han encontrado que el suelo C no necesariamente aumenta con el aumento de la entrada de basura vegetal. Las precipitaciones han aumentado en Asia central \u00e1rida y se prev\u00e9 que aumenten m\u00e1s, por lo que probamos los efectos de la adici\u00f3n de materia org\u00e1nica fresca (FOM) y agua en el secuestro de C del suelo en una regi\u00f3n \u00e1rida en el noroeste de China. Los resultados sugirieron que el FOM a\u00f1adido se descompuso r\u00e1pidamente y tuvo efectos menores en el dep\u00f3sito de carbono org\u00e1nico del suelo (SOC) a una profundidad de 30 cm. Tanto la FOM como la adici\u00f3n de agua tuvieron efectos significativos en la biomasa microbiana del suelo. La biomasa microbiana del suelo aument\u00f3 con la adici\u00f3n de FOM, alcanz\u00f3 un m\u00e1ximo y luego disminuy\u00f3 a medida que la FOM se descompon\u00eda. El FOM tuvo un efecto estimulante m\u00e1s significativo sobre la biomasa microbiana con la adici\u00f3n de agua. Bajo los rangos de humedad del suelo utilizados en este experimento (21.0% -29.7%), el aporte de FOM fue m\u00e1s importante que la adici\u00f3n de agua en el proceso de mineralizaci\u00f3n del suelo C.

Using an integrated 13C signal derived from land conversion along with measurements of soil respiration and soil carbon, we separated rapid, intermediate, and very slow turnover SOM pools, and estimated turnover times for the large intermediate pool. These estimates were compared to independent estimates using either bomb\uffe2\uff80\uff94derived soil 14C or the Century soil organic matter model. All calculations based on a three\uffe2\uff80\uff94pool SOM structure yield rates of turnover that are 3 times slower than those produced by a single pool model. Accordingly, analyses of potential feedbacks between changes in climate, atmospheric CO2, and soil carbon should incorporate the heterogeneous nature of soil organic matter. We estimate that roughly three\uffe2\uff80\uff94quarters of the carbon in the top 20 cm of these soils has turnover times less than 30 yr. Turnover times for intermediate SOM double with a 10\uffc2\uffb0C change in mean annual temperature, suggesting that recalcitrant pools of SOM may be as sensitive to changes in temperature as the smaller labile pools.</p>", "keywords": ["2.
