    ABSTRACT: The breeding population of Common Redshank Tringa totanus on British saltmarshes has reduced by >50% since 1985, with declines linked to changes in grazing management. Conservation initiatives have encouraged low-intensity grazing of 0.5 cattle ha−1 y−1 but even light grazing can lead to high rates of nest mortality. To avoid predators, Redshank nest in patches of tall vegetation, but the effects of grazing on the availability and quality of habitat selected by Redshank remain unclear. We investigated Redshank nest site selection in relation to cattle grazing and asked (a) which nest vegetation conditions do Redshank select and (b) does grazing limit the availability of higher quality nest sites? We characterised vegetation height and composition at nests and control locations on six saltmarshes grazed between 0 and 0.55 cattle ha−1 y−1, which falls within or near the UK Environment Agency definition of light grazing. Redshank selected nest locations in the tallest vegetation available (26 ± 13 cm with no grazing), but grazing limited the availability of such tall vegetation (11 ± 7 cm at 0.55 cattle ha−1 y−1). However, Redshank also selected nest locations dominated by the grass Festuca rubra, which increased with higher livestock densities. By causing Redshank to nest in shorter vegetation, but with more of their preferred grass species, grazing presented a trade-off for Redshank. As previous work has shown that nesting in shorter vegetation results in higher nest predation rates, results of this study suggest that even light conservation grazing can result in Redshank nesting in lower quality habitat. Reducing saltmarsh grazing levels below 0.55 cattle ha−1 y−1 may therefore increase Redshank populations by maintaining a vegetation structure with patches of F. rubra but with longer sward heights for nesting.

    ABSTRACT: China is a key global region vulnerable to climate change; however, limited studies have focused on the combined impacts of atmospheric CO2 enrichment and warming on crop production in arable land, especially in rice paddies in China. To address this issue, a 4 year open-air field experiment during 2010–2014 was conducted to simulate the impact of climate change on crop production in a rice paddy in southeast of China. Four treatments including the ambient condition (CK), CO2 enrichment (500 ppmv, CE), warming of canopy air (2 °C above the ambient, WA), and the combined CO2 enrichment and warming (CW) were used to investigate the responses of total biomass, crop yield and harvest index. In general, different treatments significantly affected wheat and rice production. Compared to CK, CE significantly increased grain yield of rice by 8%. In contrast, the decreases of 26.2% and 10% in wheat and rice yield were observed under WA. However, there was no significant difference of wheat production between CW and CK, while rice yield and biomass were slightly decreased by a mean of 4.8% and 5.3% over 4 years, indicating the positive effect of CO2 enrichment was unable to compensate for the negative impact of warming. The interannual variations of the responses were also observed in this study. The variation of wheat yields during 4 years was much higher than that of rice yields; however, significant changes in the stability of rice biomass and harvest index were observed under CE and WA. The results indicated both stabilizing and increasing grain yield under climate change are major challenges for agriculture in developing countries.

    ABSTRACT: Organic farming practices recommended by European regulations offer an alternative to conventional soil management, but these practices should be analyzed in greater depth to assess their effectiveness on different plants and in different local conditions. Accordingly, this study evaluates the efficacy of five different organic management strategies on an organic plum farm in Southeastern Spain. This study was conducted for a period of six years and the five different organic treatments were applied in triplicate in 256 m2 plots randomly distributed in three blocks (15 plots in total); each plot had 16 plum trees. Every year crushed pruning wastes were incorporated into the soil in all the experimental plots. One triplicated plot only received this aforementioned treatment (crop biomass treatment, CB). The rest of the plots also received one of the following treatments: (i) the addition of a commercial product for organic agriculture based on bacteria (biofertilizer), composed of Azospirillum brasilense (bacteria fixing N) and Pantoea dispersa (bacteria with a capacity for solubilising phosphates and stimulating plant growth) (biofertilizer treatment, B); (ii) the annual addition of 20 t/ha of certified commercial organic compost (annual compost treatment, AC); (iii) the biennial addition of 20 t/ha of certified commercial organic compost (biennial compost treatment, BC); and (iv) the sowing and subsequent incorporation of a mixture of 60% Avena sativa and 40% Vicia sativa (green manure treatment, GM). Each year the following indicators of ecosystem sustainability related to soil microbiological characteristics and carbon fixation were measured after harvest, in addition to plum yield: organic carbon (Corg), water soluble C, humic substances and humic acid C, microbial biomass C, respiration, ATP, dehydrogenase activity and hydrolase enzymes (alkaline phosphatase, urease and beta-glucosidase) activities. The two way ANOVA of the results indicated that all the above parameters were significantly affected (p ≤ 0.001) by both, treatment and time. The interaction of treatment and time also significantly affected all of these parameters, except for yield and dehydrogenase activity. Composts not only produced better results than green manure cover crops and biofertilizer treatments in terms of plum yields, but they also brought about higher increases in the soil C pool and greater improvements in soil microbiological characteristics. In the six years of the study, compost-treated soils showed higher average plum yields and higher organic carbon, humic substance and humic acid contents than the rest of treatments. The size and activity of microbial population was also greater in the compost-treated soils, reflected in the higher values found in these soils for microbial biomass C, soil respiration, ATP (adenosine-tri-phosphate) content and dehydrogenase and hydrolases activity. Nevertheless, yields when compost was added biennially (BC) tended to be higher than in the annual compost treatment (AC) in most years as well as on average, although the differences were usually not significant. Yields in the sixth crop showed a high positive correlation with soil humic substances and humic C content (p ≤ 0.01), as well as with Corg, microbial biomass C and phosphatase and urease activity (p ≤ 0.05).

    ABSTRACT: Although effects of water regimes on emissions of greenhouse gases (GHGs) in the growing season of rice have been well stated, it is not well documented how water regimes practiced in rice season influence GHGs and their global warming potential (GWP) over the whole annual cycle of paddy-upland crop rotation in Central China. Three water regimes during the growing season of a drought resistant rice cultivar (Oryza sativa L. subsp. indica), including continuous flooding (CF), flooded and wet intermittent irrigation (FWI), and rain-fed with limited irrigation for fertilizer application and in the case of serious drought (RFL), were initiated in 2012 in Hubei province, China. Emissions of GHGs were monitored from sowing of rapeseed (Brassica napus L.) to rice harvest in 2014, and the GWP and yield-scaled GWP were estimated from an annual rapeseed–rice rotation. Compared with CF, over the two rice seasons, FWI and RFL treatments significantly reduced methane (CH4) emissions, while apparently increased nitrous oxide (N2O) and carbon dioxide (CO2) emissions. FWI and RFL treatments practiced in rice season did not trigger significant CO2 emissions in the following rapeseed season. However, N2O emissions in the rapeseed season were significantly reduced by FWI and RFL treatments, thus there were no significantly difference in annual N2O emissions among three treatments. Although the rapeseed season showed a weak source of CH4 emission, the plots preceded by water-saving treatments continuously presented a reduction tendency in CH4 emissions in rapeseed season. Totally, in comparison to CF treatment, the averaged annual GWP over the whole rotation cycle were significantly decreased by 21% and 24% under FWI and the RFL treatments, respectively. Water-saving irrigation treatments obtained lower annual yield-scaled GWP than CF treatment. Compared with CF treatment, FWI treatment did not exhibit a yield loss in rice or rapeseed across both years. In conclusion, from a sustainable agricultural perspective, using water-saving irrigation like FWI treatment could be an effective and safe option for simultaneously realizing the three goals of saving water, mitigating GHGs and maintaining sustainable rapeseed–rice production.

    ABSTRACT: In this study, the natural isotopes of N (15N) and C (13C) were used to evaluate symbiotic N nutrition, C accumulation, and plant water-use efficiency in soybean varieties sampled from 37 farmers’ fields across the soybean-producing region of South Africa. The data revealed significant differences in all the parameters measured. Shoot dry matter ranged from 17 to 104 g plant−1, δ15N from −1.11 to +5.51‰, percent N derived from fixation from 21 to 96%, and N-fixed varied from 18 to 298 kg N ha−1. The high δ15N and low %Ndfa in some soybean genotypes were due to inhibition of N2 fixation by soil N uptake. Across the board, soybean variety PAN373 contributed the most symbiotic N (298, 242, and 217 kg N ha−1 in fields 3, 2 and 4, respectively, at Parys), followed by LS6164 (with 271 and 245 kg N ha−1 at Endcot field 1 and Devon field 2, respectively), and LS6150 (with 290 kg N ha−1 in field 1 at Parys). C concentration varied from 44 to 50% in soybean shoots, resulting in high shoot C ranging from 8 to 48 g C plant−1. The δ13C values of soybean shoots ranged from −27.3‰ to −21.1‰ in the 37 fields studied, with PAN1453 from Gransvlei field 1 and PAN737 from Parys field 4 exhibiting much greater δ13C values (−21.1‰ and −23.1‰, respectively), and hence increased water-use efficiency. The positive correlation found between N-fixed and dry matter yield (r = 0.70***), N-fixed and C content (r = 0.62***), and N-fixed and C concentration (r = 0.35*) indicates a functional relationship between N2 fixation and photosynthesis. Conventional tillage, as an agronomic tool, decreased water-use efficiency (or δ13C) in soybean plants possibly through alteration in soil structure and soil water retention. Due to a 2.6 °C higher daily maximum temperature in the North West Province than KwaZulu–Natal and Mpumalanga, soybean plants sampled from that province showed better growth, higher dry matter yield, and enhanced symbiotic performance. This argument was supported by a significantly positive correlation found between average daily maximum temperature and both dry matter yield (r = 0.39*), and N-fixed (r = 0.46**). Furthermore, the plants sampled from North West also showed much greater water-use efficiency due to a 127 and 67 mm less rainfall at that province than KwaZulu–Natal and Mpumalanga, respectively.

    ABSTRACT: Crop rotation with legumes and conservation tillage systems are advisable practices in rainfed Mediterranean agro-ecosystems, since, in these areas, soils are broadly characterized by low organic matter contents and low fertility. These management practices can substantially modify the dynamics of soil greenhouse gas (GHG) emissions, carbon sequestration and carbon dioxide (CO2) emissions derived from system inputs and farm operations. In this context, a field experiment was conducted under Mediterranean conditions to evaluate the effect of three long-term tillage systems (no tillage (NT), minimum tillage (MT) and conventional tillage (CT)) and two crops (vetch (V, Vicia sativa L.) versus barley (B, Hordeum vulgare L.)) on nitrous oxide (N2O), methane (CH4) and CO2 emissions during one year. Crop yields, soil mineral nitrogen concentrations, dissolved organic carbon and GHG fluxes were measured during the growing season. Soil organic carbon was measured in spring 2012 (18 years after the beginning of a long-term tillage experiment) and together with input and fuel consumption by farm machinery was used to compare the Global Warming Potential (GWP) of the different crop and tillage treatments. Cumulative fluxes of N2O ranged between 0.16 (B-MT) and 0.29 (V-MT) kg N2O-N ha−1 yr−1, resulting in a lower impact on Net GWP than in previous studies. A significant ‘tillage × crop’ interaction was observed in cumulative N2O emissions (V resulted in higher N2O losses than barley in CT and MT, whereas similar fluxes were observed under NT), which was influenced by soil water-filled pore space, dissolved organic carbon content and denitrification losses, in spite of the presumable predominance of nitrification. Neither tillage nor crop influenced CH4 or CO2 emissions. Yield-scaled N2O emissions (YSNE) were low (<4 g N2O-N kg aboveground N uptake−1) and significantly higher in B than in V. The most sustainable crop and tillage treatments in terms of GWP were non-fertilized-V and NT, due to higher carbon sequestration and lower fuel consumption under NT and the absence of mineral N fertilizers in V. These crop and tillage treatments could be considered good management strategies in rainfed Mediterranean agro-ecosystems since they provide the best balance between soil emissions, YSNE and Net GWP.

    ABSTRACT: The role of riparian ecosystems in mitigating the effects of diffuse agricultural sources is recognized in several regulatory measures and public policy initiatives in many parts of the world. This study aimed to evaluate the N buffering capacity of semi-natural riparian zones associated with spring-fed lowland streams, also known as “fontanili”, representing the most important groundwater-dependent ecosystems in Northern Italy. Monitoring parcels were set up in nine riparian sites selected to cover a range of different soil properties and hydrogeological settings, and to sustain the evaluation of the main drivers affecting their N removal efficiency. Subsurface water level, nutrient concentrations and the main hydro-chemical parameters were monitored along transects of piezometers installed from crop fields to the spring channels. On selected samples from two sites stable isotopes of the water molecule were also determined. Median NO3− input concentrations from adjacent cropland to the riparian sites ranged from 0.10 to 21 mg N L−1, with maximum values exceeding the drinking water limit recorded during the summer and winter fertilization periods. Highly variable groundwater nitrate patterns were found in the riparian areas, including short nitrate plumes extending from the adjacent cropland into some riparian zones, or in others, small patches where NO3− declined at variable distance from the stream. Some chemical indicators (e.g., NO3−/Cl− ratio, O2, DOC) suggested that NO3− attenuation was mostly due to the denitrifying activity occurring in the subsurface aquifers in specific conditions (hot spots and moments), although, in some cases, physical processes such as dilution also contributed. The overall N removal efficiency was greater than 90% in four sites, 74%, 34% and 30% in three sites, and zero in the remaining two sites. Useful predictors of the nitrate removal capacity were factors linked to the water residence time, such as the hydraulic conductivity, the soil texture and the slope of the riparian profile, together with the water table depth and soil organic carbon. A combination by standardized averaging of these five factors supported a clear discrimination of sites with zero or low N removal effectiveness from those with high efficiency.

    ABSTRACT: Knowledge of soil carbon (C) dynamics following vegetation restoration is essential for evaluating carbon budgets and cycles at regional and global scales. In this study, we investigated the dynamics of soil organic carbon (OC) following farmland abandonment along with ∼160 years of vegetation restoration on the Loess Plateau, China. Our specific objectives were to examine the variation of soil OC decomposition rates, to quantify the changes in the proportion of new and old soil OC, and to explore the factors controlling soil OC stock patterns. The results showed that the rate of new soil OC increase was higher in the early stage (∼10 years) after land-use change. The rate of new soil OC increase ranged from 109.17 to 41.88 g m−2 year−1 in the early (∼10 years) and later stages (∼160 years), respectively. It took about 30 years for the amount of new soil OC to reach the same level as old OC in the top 20 cm of soil following farmland abandonment. Also, soil OC decomposition rate was higher (decomposition rate constants = 0.04) in the early stage (∼10 years) and showed a non-significant difference after > 30 years of vegetation restoration. Our results suggested that soil C/N is the most factor to effect on soil OC sequestration following vegetation restoration, and the proportions of new soil OC was mainly determined by fine roots, soil OC decomposition rate constants were mainly determined by soil silt content, and the rates of new soil OC increase were mainly determined by soil sand content that these observations were made out of considering many other soil properties.

    ABSTRACT: Separation of natural and anthropogenic influences is required to identify land-use impacts on stream ecosystems. We investigated the effects of water quality and riparian condition on invertebrate assemblages along streams draining agricultural land by partitioning out changes in geomorphological characteristics. There was a strong negative relationship between invertebrate richness and distance downstream, driven by a gradient of reducing stream power and substratum particle size along the streams. When substratum particle size was accounted for, richness was reduced by ∼24% when there was limited availability of coarse particulate organic matter, resulting from lower riparian forest cover upstream. High concentrations of fertilizer-derived nitrate boosted invertebrate abundances, but only in mid sections of streams, where coarse substrata (>100 mm) and high insolation were available. Sampling of multiple sites along streams facilitated partitioning of land-use impacts from natural gradients. Invertebrate richness was a good indicator of stream biophysical condition (e.g. nature of the substratum, riparian condition) at the stream scale irrespective of taxonomic resolution (family or higher) or sample size (down to 50 individuals per site), and was therefore a useful monitoring tool. The finding that riparian vegetation is a key determinant of invertebrate diversity should encourage catchment-scale maintenance and rehabilitation of native riparian forest.
