Quantifying soil respiration in response to short-term tillage practices: a case study in southern Turkey

Abstract

The study aimed at quantifying the rates of soil CO 2 efflux under the influence of common tillage systems of moldboard plow (PT), chisel plow (CT), rotary tiller (RT), heavy disc harrow (DT), and no-tillage (NT) for 46 days in October and November in a field left fallow after wheat harvest located in southern Turkey. The NT and DT plots produced the lowest soil CO 2 effluxes of 0.3 and 0.7 g m (2 h (1 , respectively, relative to the other plots (P B0.001). Following the highest rainfall amount of 87 mm on the tenth day after the tillage, soil CO 2 efflux rates of all the plots peaked on the 12th day, with less influence on soil CO 2 efflux in the NT plot than in the conventional tillage plots. Soil evaporation in NT (64 mmol m (2 s (1 ) was significantly lower than in the PT (85 mmol m (2 s (1 ) and RT (89 mmol m (2 s (1 ) tillage treatments (P B0.01). The best multiple-regression model selected explained 46% of variation in soil respiration rates as a function of the tillage treatments, soil temperature, and soil evaporation (P B0.001). The tillage systems of RT, PT, and CT led, on average, to 0.23, 0.22, and 0.18 g m (2 h (1 more soil CO 2 efflux than the baseline of NT, respectively (P 50.001).

Effects of autumn tillage and residue management on soil respiration in a long‐term field experiment in Sweden

“…In general, reduced tillage or no tillage decreases soil respiration compared with conventional tillage ( e.g. , Alvarez et al, 1995; Prior et al, 2000; La Scala et al, 2006; Akbolat et al, 2008). However, respiration responses to tillage reported in the literature are not consistent.…”

Effects of Residue Management and Cropping Systems on Wheat Yield Stability in a Semiarid Mediterranean Clay Soil

“…Morocco's agriculture should experience a shift based upon conservation and intensification. In the other side, world-wide and in the Mediterranean basin, No-tillage systems are among the top technologies to mitigate drought, reduce tillage costs, conserve soil and water, increase soil organic carbon pools, boost crop productivity and reduce net CO 2 emissions, which contribute to global warming attenuation [5][6][7]. Hence, under these environmental and weather conditions, to increase the yield stability in cereal crops represents an important objective for agricultural progress.…”

Control Over River Bank Erosion: A Case Study of Ganetti Station, Northern States, Sudan

“…A fundamental challenge of sustaining the productivity, biodiversity and integrity of ecosystems regionally and globally is to ensure that local decision makers including individual land users, groups, or institutions use the quantification of the biophysical potential of ecosystems obtained by land evaluation. On the other hand the quantifying soil respiration in response to short-term tillage practices and climate change plays a large role in the erosion of the soil [3].…”
