“…8) and the positive correlation coefficient (r) varies from 0.64 to 0.81 with is significant for all eight measurement sites (non directional p b 0.001). The increased emission with temperature has also been noted in other studies such as Glenn et al (1993), Silvola et al (1996a), Akinremi et al (1998), Koizumi et al (1999), Maljanen et al (2001a,b). The CO 2 emission has variable negative correlation with soil moisture on average − 0.42 with significant correlation at sites Gb and A, −0.53 and −0.83 respectively.…”

“…This could be attributed to the soil properties, the types of weed species and a better water use efficiency of individual weed families (Bolandnazar et al, 2007). Soil types influencing the abundance of plant communities are in conformity with most earlier research (Koizumi et al, 1999;Echevarria et al, 2003;Mako et al, 2008;Bestland et al, 2009;Clark et al, 2011; Figure 5 Mycorrhization of field pea roots at different soil types (gleyic phaeozem -F -soils , sandy calcaric phaeozem -S -soils and calcic chernozem -T -soils ), under current and prognosticated rainfall patterns.

“…S -soils are highly sandy, with very low profile water and evaporation; F -soils have very high clay content, highly mottled subsoils, with high profile water and evaporation; while T -soils are highly silty with the highest profile water content (Table 1). Soil types and its characteristics have been demonstrated to affect several processes in agroecosystems, such as the availability and supply of water to plants (Passioura, 1991), respiration and soil temperature (Koizumi et al, 1999), plant growth, vegetation cover and yield (Mako et al, 2008;Bestland et al, 2009;Genxu et al, 2009), the transfer and interaction of mineral nutrients (Echevarria et al, 2003;Matias et al, 2011), and the physical, chemical and biochemical properties of soils (Rhoton et al, 1993;Paz-Ferreiro et al, 2011), while higher soil sand content has been shown to improve AMF colonisation (Zaller et al, 2011).…”

Soil types will alter the response of arable agroecosystems to future rainfall patterns

Climate change scenarios for central Europe predict fewer but heavier rains during the vegetation period without substantial changes in the total amount of annual rainfall. To investigate the impact of rainfall patterns derived from regionalised IPCC scenarios on agroecosystems in Austria, we conducted an experiment using 3 m 2 lysimeters where prognosticated (progn.) rainfall patterns were compared with long-term current rainfall patterns on three agriculturally important soil types (sandy calcaric phaeozem, gleyic phaeozem and calcic chernozem). Lysimeters were cultivated with field peas (Pisum sativum) according to good farming practice. Prognosticated rainfall patterns decreased crop cover, net primary production (NPP) and crop yields, but increased root production and tended to decrease mycorrhization. Soil types affected the NPP, crop density and yields, weed biomass and composition, as well as the root production with lowest values commonly found in sandy soils, while other soil types showed almost similar effects. Significant interactions between rainfall patterns and soil types were observed for the harvest index (ratio crop yield versus straw), yield per crop plant, weed density and weed community composition. Abundance of the insect pest pea moth (Cydia nigricana) tended to be higher under progn. rainfall, but was unaffected by soil types. These results show that (a) future rainfall patterns will substantially affect various agroecosystem processes and crop production in the studied region, and (b) the influence of different soil types in altering ecosystem responses to climate change should be considered when attempting to scale-up experimental results derived at the plot level to the landscape level.

“…Initial lowering of the water table generally increases the N 2 O emission rate but the long-term influence of drainage depth is not as straightforward (Regina et al, 1996;Maljanen et al, 2003c;Klemedtsson et al, 2005) Many investigations of GHG emissions from peat soils have been conducted under uncontrolled conditions in the field (Nykänen et al, 1995;Freeman et al, 1996;Silvola et al, 1996;Flessa et al, 1998) or on disturbed soil samples (Freeman et al, 1996;Aerts and Ludwig, 1997;Best and Jacobs, 1997;Chapman and Thurlow, 1998) where the original structure of the peat profile and its characteristic hydrological features are lost. Information on the peat soil profile and the properties of the soils has in many cases been lacking or insufficient (Freeman et al, 1996;Koizumi et al, 1999;Regina et al, 2004), which makes interpretation of the results difficult. An essential feature in this study is the emission measurements from intact soil cores together with the collection of associated soil property data.…”

A lysimeter method using undisturbed soil columns was used to investigate the effect of water table depth and soil properties on soil organic matter decomposition and greenhouse gas (GHG) emissions from cultivated peat soils. The study was carried out using cultivated organic soils from two locations in Sweden: Örke, a typical cultivated fen peat with low pH and high organic matter content and Majnegården, a more uncommon fen peat type with high pH and low organic matter content. Even though carbon and nitrogen contents differ greatly between the sites, carbon and nitrogen density are quite similar. A drilling method with minimal soil disturbance was used to collect 12 undisturbed soil monoliths (50 cm high, ⌀29.5 cm) per site. They were sown with ryegrass (Lolium perenne) after the original vegetation was removed. The lysimeter design allowed the introduction of water at depth so as to maintain a constant water table at either 40 cm or 80 cm below the soil surface. CO 2 , CH 4 and N 2 O emissions from the lysimeters were measured weekly and complemented with incubation experiments with small undisturbed soil cores subjected to different tensions (5, 40, 80 and 600 cm water column). CO 2 emissions were greater from the treatment with the high water table level (40 cm) compared with the low level (80 cm). N 2 O emissions peaked in springtime and CH 4 emissions were very low or negative. Estimated GHG emissions during one year were between 2.70 and 3.55 kg CO 2 equivalents m -2 . The results from the incubation experiment were in agreement with emissions results from the lysimeter experiments. We attribute the observed differences in GHG emissions between the soils to the contrasting dry matter liability and soil physical properties. The properties of the different soil layers will determine the effect of water table regulation. Lowering the water table without exposing new layers with easily decomposable material would have a limited effect on emission rates.
