“…Although liming is a common agricultural practice and the effect on soil properties has been extensively studied, the effect on soil organic matter (SOM) stocks is still poorly known (Paradelo et al, 2015). This is due to the fact that multiple factors may result in different net effects on SOM.…”

“…Hereafter, we present some examples of recently published metaanalyses on the impacts of irrigation , tillage (Virto et al 2012), liming (Paradelo et al 2015) and fertilisation (Han et al 2016;Yue et al 2016) on soil C stocks.…”

“…However, secondary practices of no-till cropping systems (implemented to offset the lack of tillage, as the choice of cropped species and the number of rotations) showed positive effects on C storage (Virto et al 2012). Paradelo et al (2015) reviewed the results of 29 studies considering the effects of liming on soil C stocks. Their meta-analysis did not reveal an unambiguous effect of liming on C storage.…”

The international 4 per 1000 initiative aims at supporting states and non-governmental stakeholders in their efforts towards a better management of soil carbon (C) stocks. These stocks depend on soil C inputs and outputs. They are the result of fine spatial scale interconnected mechanisms, which stabilise/destabilise organic matter-borne C. Since 2016, the CarboSMS consortium federates French researchers working on these mechanisms and their effects on C stocks in a local and global change setting (land use, agricultural practices, climatic and soil conditions, etc.). This article is a synthesis of this consortium's first seminar. In the first part, we present recent advances in the understanding of soil C stabilisation mechanisms comprising biotic and abiotic processes, which occur concomitantly and interact. Soil organic C stocks are altered by biotic activities of plants (the main source of C through litter and root systems), microorganisms (fungi and bacteria) and 'ecosystem engineers' (earthworms, termites, ants). In the meantime, abiotic processes related to the soil-physical structure, porosity and mineral fraction also modify these stocks. In the second part, we show how agricultural practices affect soil C stocks. By acting on both biotic and abiotic mechanisms, land use and management practices This synthesis of the CarboSMS French consortium's first seminar was already published in French: Derrien D, Dignac M-F, Basile-Doelsch I, Barot S, Cécillon L, Chenu C, Chevallier T, Freschet GT, Garnier P, Guenet B, Hedde M, Klumpp K, Lashermes G, Maron P-A, Nunan N, Roumet C, Barré P (2016) (choice of plant species and density, plant residue exports, amendments, fertilisation, tillage, etc.) drive soil spatiotemporal organic inputs and organic matter sensitivity to mineralisation. Interaction between the different mechanisms and their effects on C stocks are revealed by meta-analyses and long-term field studies. The third part addresses upscaling issues. This is a cause for major concern since soil organic C stabilisation mechanisms are most often studied at fine spatial scales (mm-μm) under controlled conditions, while agricultural practices are implemented at the plot scale. We discuss some proxies and models describing specific mechanisms and their action in different soil and climatic contexts and show how they should be taken into account in large scale models, to improve change predictions in soil C stocks. Finally, this literature review highlights some future research prospects geared towards preserving or even increasing C stocks, our focus being put on the mechanisms, the effects of agricultural practices on them and C stock prediction models.

“…The main task of soil liming is to ensure favourable conditions for plant nutrition. Liming increases soil organic matter in mineral soils due to higher C inputs and productivity (Paradelo et al, 2015). Long-term experiments in Lithuania show that systematic periodical liming over 56 years (by 0.5 rates every 7 years and 2.0 rates every 3-4 years) on the background of minimal organic fertilizing and conventional tillage, has a positive effect on the structure of moraine loam soil (Bathygleyic Dystric Glossic Retisol).…”

The paper describes the influence of long-term (more than 30 years) fertilizer and lime application on the soil acidity (pH Cl ) and identifies the influence of soil acidity on the productivity of crops. Since 1994, a seven-year crop rotation was created: (1) winter triticale → (2) potatoes → (3) spring wheat → (4) spring oilseed rape → (5) spring barley → (6) and (7) perennial grasses (red clover, timothy), 1 st and 2 nd year of use. At the beginning of the experiment, the soil in treatments F0 and F2 was very strongly acid (pH KCl 4.7) but in treatments F1 and F3 -moderately acid (pH KCl 5.6). In limed treatments the soil acidity decreased from pH 4.8 to pH 5.8-6.0. In the following years till 1994, the soil acidity in limed treatments gradually increased (for about 0.4-0.6 pH units). After the first maintenance liming, the soil acidity reached nearly the previous highest level. Within the next twenty years, in the treatments with highest liming rate (11.40 t ha -1 CaCO 3 ) the soil acidity increased to pH 5.2. In treatments with low liming rate (2.58 t ha -1 CaCO 3 ), the soil acidity increased to pH 4.6, which was even lower than at the beginning of the experiment (pH 4.8). Without maintenance liming, the soil acidity during 20 years increased by 0.7-0.8 pH units. In the unlimed treatments, the soil acidity gradually increased from pH 4.8 to 4.4.
