“…With the impossibility of place lime in deeper layers in no-till system after implementation, the carbonate tends to decrease over time. As reported by Wang et al (2015), the decrease of carbonate in soil tends to increase the acidification, which results in increasing Al +3 and H + saturation in soil. The calcium, potassium and magnesium saturation were higher in topsoil, which differed from the other layers evaluated ( Fig 2).…”

The purpose of this study was to assess the changes in soil chemical properties affected by the cover crops cultivated in crop rotation in short-term of no-till implementation under Rhodic Hapludox soil. This research was carried out from October 2010 to February 2014. The experiment was set up in completely randomized blocks in a factorial design with eight treatments (cover crops) and three soil depths (0-5, 5-10 and 10-20 cm) with four repetitions. The cover crops were: fall-winter maize (T 1), intercropping fall-winter maize with B. ruziziensis (T 2), intercropping fall-winter maize with B. brizantha cv. Marandu (T 3), intercropping fall-winter maize with Crotalaria spectabilis (T 4), B. ruziziensis (T 5), B. brizantha cv. Marandu (T 6), Pennisetum glaucum L. (T 7) and fallow (T 8). The T 6 and T 7 affected exchangeable Mg +2 , it was observed higher exchangeable Mg +2 in T 6 (2.39 cmol c dm-3) and T 7 (2.43 cmol c dm-3) in comparison to T 1. The phosphorus content showed interactive effect between cover crops and soil depth. In the comparison among the depths, the P contents were higher in 5-10 cm, which showed improvement of 24.6% and 25.2% in comparison to 0-5 and 10-20 cm layers, respectively. The cover crops evaluated in this research affected the exchangeable Mg +2 and K + , as well as Mg +2 and K + saturation. The P content changed in response of cover crops, which was important to observe that this nutrient may increase the content with adoption of cover crops in no-till system. The species used in this research might be recommended to integrate a crop rotation system with the possibility of increasing P availability in topsoil depth in no-till system.

“…Additionally, obtaining the different carbon components remains a prerequisite to identify which components are critical in determining whether an ecosystem is a carbon sink or source. However, the most recent efforts on detailed carbon budget components remain only limited to a few studies on forests (Iglesias et al, 2013;Wu et al, 2013) and agroecosystems (e.g., Moureaux et al, 2008;Wang et al, 2015;Demyan et al, 2016).…”

Carbon sequestration of cropland has the potential to mitigate global greenhouse gas emissions. To understand such sequestration of an irrigated wheat-maize rotation cropland with high groundwater table in the North China Plain, the carbon budget and its components are estimated with a comprehensive field experiment by combining eddy covariance technique, soil respiration experiment differentiating heterotrophic and below-ground autotrophic respirations, and biometric measurements in a relatively wet year from October 2010 to October 2011. In the experimental period of a whole winter-wheat and summer-maize cycle, the Net Ecosystem Exchange, Gross Primary Productivity, Ecosystem Respiration, soil heterotrophic respiration, below-ground autotrophic respiration and above-ground autotrophic respiration are &minus;437.9, 1078.2, 640.4, 376.8, 135.5 and 128.0&thinsp;gC&thinsp;m&minus;2, respectively for wheat season, and are &minus;238.8, 779.7, 540.8, 292.2, 115.4 and 133.2&thinsp;gC&thinsp;m&minus;2, respectively for maize season. The experiment allows for estimations of Net Primary Productivity, Net Ecosystem Productivity and Net Biome Productivity. The Net Biome Productivity are 58.8 and 3.9&thinsp;gC&thinsp;m&minus;2 for wheat and maize season, indicating that wheat is a carbon sink and maize is close to carbon neutral. However, compensated by the net ecosystem carbon release in two rotation periods, Net Biome Productivity of the whole wheat-maize rotation cycle is 12.8&thinsp;gC&thinsp;m&minus;2&thinsp;yr&minus;1 in the experimental year, indicating this cropland remains a weak carbon sink under the specific climatic conditions and field conditions with a high groundwater table. The cropland has a higher ecosystem carbon use efficiency (CUE) than other terrestrial ecosystems, indicating that the agro-ecosystem is more efficient in harvesting CO2 from the atmosphere. This irrigated wheat-maize rotation cropland with high groundwater table has higher CUE than other croplands, implying that the cropland management of full irrigation and fertilization promotes carbon accumulation in crops.

“…In recent years, an increasing number of studies have been done using the eddy covariance (EC) technique to address how carbon and water fluxes over croplands vary (1) in contrasting growing seasons or over a long-term period at one site (Buysse et al, 2017;Dufranne et al, 2011;Saito et al, 2005;Schmidt et al, 2012), (2) by different crop rotations (e.g., Akuraju et al, 2013;Alberti et al, 2010;Aubinet et al, 2009;Béziat, Ceschia, & Dedieu, 2009;Kutsch et al, 2010;Parent & Anctil, 2012;Taylor, Amiro, & Fraser, 2013;Wang et al, 2015), and (3) by tillage practice conversion within one site . There have been few studies using co-located and multiple EC flux towers within one crop production region to investigate the impacts of different management practices and local meteorological conditions on agricultural carbon and water cycling: Suyker and Verma (2012) used flux measurements over 8 years to compare the carbon fluxes between irrigated and rain-fed cropping systems in Nebraska; Verma et al (2005) compared carbon budgets between an irrigated corn field, an irrigated corn-soybean field, and a dryland corn field to investigate irrigation impacts on agricultural carbon cycling for the same site; Davis et al (2010) established two EC towers in Ireland to assess the effects of different tillage practices on carbon budgets and the spatial variation; and Baker and Griffis (2005) used EC measurements to compare the carbon budgets under conventional tillage and strip tillage conditions at two adjacent fields in Minnesota.…”

Effects of Climatic Conditions and Management Practices on Agricultural Carbon and Water Budgets in the Inland Pacific Northwest USA

Cropland is an important land cover influencing global carbon and water cycles. Variability of agricultural carbon and water fluxes depends on crop species, management practices, soil characteristics, and climatic conditions. In the context of climate change, it is critical to quantify the long‐term effects of these environmental drivers and farming activities on carbon and water dynamics. Twenty site‐years of carbon and water fluxes covering a large precipitation gradient and a variety of crop species and management practices were measured in the inland Pacific Northwest using the eddy covariance method. The rain‐fed fields were net carbon sinks, while the irrigated site was close to carbon neutral during the winter wheat crop years. Sites growing spring crops were either carbon sinks, sources, or neutral, varying with crops, rainfall zones, and tillage practices. Fluxes were more sensitive to variability in precipitation than temperature: annual carbon and water fluxes increased with the increasing precipitation while only respiration increased with temperature in the high‐rainfall area. Compared to a nearby rain‐fed site, irrigation improved winter wheat production but resulted in large losses of carbon and water to the atmosphere. Compared to conventional tillage, no‐till had significantly lower respiration but resulted in slightly lower yields and water use efficiency over 4 years. Under future climate change, it is expected that more carbon fixation by crops and evapotranspiration would occur in a warmer and wetter environment.
