Climate change is also projected to influence the rainfall amount, and its inter- and intra-annual variability. These changes may affect soil moisture regimes, soil water drainage, soil nitrogen (N) availability and N leaching to aquatic environment and N2O emissions to atmosphere. Thus it is important to study the effects of increased soil temperature and varying rainfall patterns on soil N cycling in arable land from temperate climates, which is a major source of N pollution. An open-field lysimeter study was carried out during 2008\u20132009 in Denmark on loamy sand soil (Typic Hapludult) with three factors: number of rainy days, rainfall amount and soil warming. Number of rainy days included the mean monthly rainy days for 1961\u20131990 as \u2018normal\u2019 and half the number of rainy days of former as \u2018reduced\u2019 treatments. Rainfall amount included mean monthly rainfall for 1961\u20131990 as \u2018present\u2019 and the projected change in mean monthly rainfall for 2071\u20132100 as \u2018future\u2019 treatments. Soil warming included increase in soil temperature by 5\u00a0\u00b0C at 0.1\u00a0m depth as \u2018heated\u2019 and non-heated as \u2018control\u2019 treatments. Automated mobile rain-out shelter and irrigation system, and insulated buried heating cables were used to impose the treatments.  Soil warming, compared with unheated control, advanced winter wheat crop development, and increased the above-ground biomass and N uptake only during vegetative stage, but shortened the total crop growing period by 12 days without reducing the total above-ground biomass. Rainfall amount and rainy days treatments increased the drainage, 46% and 10%, respectively, but did not have additive effect on the drainage. In contrast, soil warming increased crop evapotranspiration (18%) and reduced drainage (41%). The projected future rainfall amount increased NO3-N leaching (289%) compared with present rainfall amount. The study showed significant interaction between soil warming and rainfall amount (P", "keywords": ["Nitrate leaching", "Winter wheat", "2. Zero hunger", "Soil nitrogen", "BRIC", "13.

In a field scale experiment on temperate heathland, manipulation of precipitation and temperature was performed with retractable curtains, and atmospheric CO2 concentration was increased by FACE. The combination of elevated CO2 and warming was expected to affect belowground processes additively, through increased belowground sequestration of labile carbohydrates due to elevated CO2 in combination with temperature increased process rates. Together, these changes might increase microbial activity and availability of plant nutrients. Two years after the start of the experiment, belowground processes responded significantly to the treatments. In the combined temperature and CO2 treatment the dissolved organic nitrogen concentration decreased and the ammonium concentration increased, but this release of nutrients was not mirrored by plant parameters. Microbial biomass carbon and microbial enrichment with 13C and 15N (1\u00a0year after 13C                   2                   15                 N-glycine was injected into the soil) increased in warmed plots and in elevated CO2 plots, but not when these treatments were combined. Furthermore, drought led to an increase in Calluna biomass and total plant nitrogen pool. The full combination of warming, elevated CO2 and periodic drought did not unambiguously express the ecosystem responses of single factors additively, which complicates predictions of ecosystem responses to multifactor climate change.", "keywords": ["0106 biological sciences", "2.

PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for 6 weeks until final harvest. Analysis across the soil textures showed that fresh yields were not significant between the irrigation treatments. However, the same analysis across the irrigation treatments revealed that the effect of soil texture was significant on the fresh yield and loamy sand produced significantly higher fresh yield than the other two soils, probably because of higher leaf area index, higher photosynthesis rates, and \u201cstay-green\u201d effect late in the growing season. More analysis showed that there was a significant interaction between the irrigation treatments and soil textures that the highest fresh yield was obtained under FI in loamy sand. Furthermore, analysis across the soil textures showed that water productivities, WP (kg\u00a0ha\u22121 fresh tuber yield\u00a0mm\u22121 ET) were not significantly different between the irrigation treatments. However, across the irrigation treatments, the soil textures were significantly different. This showed that the interaction between irrigation treatments and soil textures was significant that the highest significant WP was obtained under DI in sandy loam. While PRD and DI treatments increased WP by, respectively, 11 and 5% in coarse sand and 28 and 36% in sandy loam relative to FI, they decreased WP in loamy sand by 15 and 13%. The reduced WP in loamy sand was due to nearly 28% fresh tuber yield loss in PRD and DI relative to FI even though ET was reduced by 9 and 11% in these irrigation treatments. This study showed that different soils will affect water-saving irrigation strategies that are worth knowing for suitable agricultural water management. So, under non-limited water resources conditions, loamy sand produces the highest yield under full irrigation but water-saving irrigations (PRD and DI) are not recommended due to considerable loss (28%) in yield. However, under restricted water resources, it is recommended to apply water-saving irrigations in sandy loam and coarse sand to achieve the highest water productivity.", "keywords": ["0106 biological sciences", "2.
