“…Soil water content also increased under NT soils compared with CT soils, but the effect was lower than that in SS soils. This result is consistent with previous studies of Cai et al (2014) who reported increased soil water in subsoiling. The average water-filled pore space was highest (P < 0.05) in the SS (18%) and NT (13%) compared with CT (Table 1).…”

In semi-arid areas, increasing CO<sub>2</sub> emissions are threatening agricultural sustainability. It is unclear whether different tillage practices without residue returned could help alleviate these issues while increasing crop productivity. This study aimed to quantify soil respiration under conventional tillage (CT); rotary tillage (RT); subsoiling (SS) and no-till (NT), all without residue returned in the Western Loess Plateau. The results showed that SS and NT significantly decreased soil respiration compared to CT, but the effects of SS was the greatest. As a result, SS decreased carbon emission by 22% in 2014 and 19% in 2015 versus CT. The trends of net ecosystem production under different tillage systems were as follows: CT > RT > NT > SS. No-till increased net ecosystem production by 33% in 2014 and 12% in 2015 relative to CT. The SS treatment increased average grain yield by 27% and 23% over CT and RT, and enhanced water use efficiency by an average of 43%. On average, SS increased carbon emission efficiency by 60% and 43% compared to CT and RT, respectively. Thus, subsoiling management strategy is a promising option for the development of sustainable agriculture in semi-arid areas.

“…Subsoil compaction is caused by ever increasing wheel loads in agricultural machinery for agricultural land, which is becoming a global problem. It presented increasing risk in both developed and developing countries (Cai et al, 2014;Bertolino et al, 2010). In Northeast China, plough pan formation is considered to be a consequence of conventional tillage practices.…”

This study aims to investigate the responses of carbon assimilation, grain yield, leaf stay-green rate, nitrogen uptake and distribution to soil compaction in the hard plow pan caused by repeated use of tractor-driven cultivator in Northeast China. The typical hybrid maize variety “Zhengdan 958” was exposed to two treatments of simulated plow pan (SP) and simulated subsoiling (SS, control) in pot experiments from 2012 to 2014. Compared with SS, SP significantly reduced net photosynthetic rate (Pn) during growth stage, leading to a decrease in dry matter accumulation (DMA) and grain yield (GY) in three consecutive experimental years. Leaf stay-green degrees (LSD), which showed a fast descending trend from 20 days after silking (DAS), significantly decreased in the later filling stage under SP treatment. The translocation eﬃciency of the stored N (TEN) in stalk and leaf to the grain during pre-silking was enhanced, whereas leaf and grain N concentration (LNC/GNC), together with N accumulation amounts at maturity were significantly reduced under SP treatment. Also, plough pan reduced the N distribution to the organs of stalk, leaf and grain. In conclusion, subsoiling is a possible way to delay leaf senescence and achieve higher DMA and GY, and increased grain N in the corn belt of Northeast China.

“…In NEC, long-term continuous cropping is dominated by small-sized four-wheeled tractors; because of the overexploitation of the soil as well as improper mechanical manipulation of the soil, the effective plow layer has gradually decreased and the plow pan layer has thickened (approximately 5-10 cm; Liu et al 2008). The average effective plow layer depth is only 15.1 cm in NEC (against an average of 16.5 cm in China), much shallower than that in the North America, which usually reaches 35 cm on average (Cai et al 2014). The shallow and compacted topsoil not only restricts the root development of plants but hinders their absorption of nutrients and water.…”

“…The shallow and compacted topsoil not only restricts the root development of plants but hinders their absorption of nutrients and water. The poor soil properties also reduce their tolerance to abiotic stress, especially resistance against natural disasters (Zhang and Li 2010;Cai et al 2014). To improve the situation farmers should follow recommendations of agronomists to increase the health of the soil by incorporation of crop residue and appropriate tillage.…”

Narrowing the Agronomic Yield Gaps of Maize by Improved Soil, Cultivar, and Agricultural Management Practices in Different Climate Zones of Northeast China

Northeast China (NEC) is one of the major agricultural production areas in China, producing about 30% of China's total maize output. In the past five decades, maize yields in NEC increased rapidly. However, farmer yields still have potential to be increased. Therefore, it is important to quantify the impacts of agronomic factors, including soil physical properties, cultivar selections, and management practices on yield gaps of maize under the changing climate in NEC in order to provide reliable recommendations to narrow down the yield gaps. In this study, the Agricultural Production Systems Simulator (APSIM)-Maize model was used to separate the contributions of soil physical properties, cultivar selections, and management practices to maize yield gaps. The results indicate that approximately 5%, 12%, and 18% of potential yield loss of maize is attributable to soil physical properties, cultivar selection, and management practices. Simulation analyses showed that potential ascensions of yield of maize by improving soil physical properties PAY s , changing to cultivar with longer maturity PAY c , and improving management practices PAY m for the entire region were 0.6, 1.5, and 2.2 ton ha 21 or 9%, 23%, and 34% increases, respectively, in NEC. In addition, PAY c and PAY m varied considerably from location to location (0.4 to 2.2 and 0.9 to 4.5 ton ha 21 respectively), which may be associated with the spatial variation of growing season temperature and precipitation among climate zones in NEC. Therefore, changing to cultivars with longer growing season requirement and improving management practices are the top strategies for improving yield of maize in NEC, especially for the north and west areas.
