“…After the harvest, the quantity of productive ear, seeds per ear, plant biomass and the thousand kernel weight (TKW) were tested for spring wheat yield evaluation [28] . For silage corn, the fresh weights of plant, leaf, stem and cluster were used as the yield indexes [29] .…”

Xinjiang Region of China is one of the most typical and representative arid areas worldwide, along with severe soil salinization issue. Planting spring wheat and sequential cropping silage corn in Northern Xinjiang using drip irrigation has become an effective way to relieve soil salinity stress, which improves the simple agricultural structure in the past and ensures food security in this area. However, neither the effects of different soil salinities on the growth and yield of spring wheat and silage corn, nor their desalination effect correspondingly was clear until now. Therefore, a pot experiment was conducted at Shihezi, Xinjiang from March to June 2015. The study aimed to establish the quantitative correlations between the parameters mentioned above and came up with the appropriate soil salinity threshold in Northern Xinjiang area. The results confirmed that the soils in all treatments were desalinated after the whole growth period, and the decreasing rates varied within 18.89%-44.08% and 11.06%-30.83% for two plants, which showed linear and quadratic correlations with initial soil salinity, respectively (R 2 >0.92**, p<0.05). Meanwhile, higher soil salinity would inhibit crop growth and yield, and the initial soil salinity also represented the negative quadratic correlations with growth parameters (R 2 >0.92**, p<0.01). The inhibition effect was enhanced with larger initial soil salinity. After the comprehensive consideration of soil salinity variation, crop growth and yield, the initial soil salinity was recommended under 8.91 g/kg and 5.54 g/kg to plant spring wheat and sequential cropping silage corn in Northern Xinjiang using drip irrigation.

“…This effect was limited under the increasing drought conditions predicted by the Had3 scenario ( Figure S1), in which the water availability may be a limiting factor for plant growth. Experimental data of double cropping systems reported both higher water consumption (Meza et al, 2008) and invariant water content and higher yields (Fouli et al, 2012). It is clear that interactions and feedbacks between climate, rotations and carbon and nitrogen biogeochemical cycles are very complex, confirming the importance of developing a tool at high spatial resolution.…”

Bottom-up estimates from long-term field experiments and modelling are the most commonly used approaches to estimate the carbon (C) sequestration potential of the agricultural sector. However, when data are required at European level, important margins of uncertainty still exist due to the representativeness of local data at large scale or different assumptions and information utilized for running models. In this context, a pan-European (EU + Serbia, Bosnia and Herzegovina, Montenegro, Albania, Former Yugoslav Republic of Macedonia and Norway) simulation platform with high spatial resolution and harmonized data sets was developed to provide consistent scenarios in support of possible carbon sequestration policies. Using the CENTURY agroecosystem model, six alternative management practices (AMP) scenarios were assessed as alternatives to the business as usual situation (BAU). These consisted of the conversion of arable land to grassland (and vice versa), straw incorporation, reduced tillage, straw incorporation combined with reduced tillage, ley cropping system and cover crops. The conversion into grassland showed the highest soil organic carbon (SOC) sequestration rates, ranging between 0.4 and 0.8 t C ha À1 yr À1 , while the opposite extreme scenario (100% of grassland conversion into arable) gave cumulated losses of up to 2 Gt of C by 2100. Among the other practices, ley cropping systems and cover crops gave better performances than straw incorporation and reduced tillage. The allocation of 12 to 28% of the European arable land to different AMP combinations resulted in a potential SOC sequestration of 101-336 Mt CO 2 eq. by 2020 and 549-2141 Mt CO 2 eq. by 2100. Modelled carbon sequestration rates compared with values from an ad hoc meta-analysis confirmed the robustness of these estimates.

Sustainable intensification of agricultural systems has been suggested – in addition to reducing waste and changing consumption habits – as a way to increase food, feed, fuel, and fiber security in the twenty‐first century. Here we describe three primary strategies of agricultural intensification – conventional intensification, temporal intensification, and spatial intensification – and how they can be used to manage and integrate food and second‐generation crop portfolios. While each strategy has individual merits, combining them to meet case‐specific targets may achieve optimum results. Multiple experiments and examples from the USA and the EU illustrate the potential of combining these approaches for agroecological intensification that can provide ecosystem services while maintaining or increasing economic output, thus striking a balance between ‘land sparing’ and ‘land sharing’. Management strategies will vary by the types of markets available, e.g., food, fuel and/or ecosystem services, and the scale of markets supplied, e.g., small heat and power vs. large cellulosic ethanol. Future research should holistically and methodologically evaluate the trade‐offs between different management strategies. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
