Soil C and N dynamics and hydrological processes in a maize-wheat rotation field subjected to different tillage and straw management practices

Abstract

HighlightsMaize yield was enhanced by straw returning while there was no significant tillage effect.Both reduced tillage and straw returning significantly decreased runoff.Straw returning reduced soil water evaporation but increased water transpiration.Soils subjected to all the treatments acted as C and N sinks in this study.

Can reduced tillage buffer the future climate warming effects on maize yield in different soil types of West Africa?

“…In agreement with the results from Fuentes et al (2003), Wang et al (2019), andXu et al (2019), improved maize yield could be attributed to higher soil nutrient stocks, soil organic carbon and improved NUE of maize crop under the reduced tillage system, which was also observed during the field experiment in this site (Nafi et al, 2020(Nafi et al, , 2019. Enhanced soil water under reduced tillage and crop residue incorporation at the footslope in Dassari resulted in improved soil properties that stimulated maize yield (Liu et al, 2012;Wang et al, 2019). In all soil types located in the upslope positions, St2 (Eutric Plinthosol, upslope in Dano) and St4 (Plinthic Lixisol, upslope in Dassari), implementation of contour ridge tillage together with crop residue application instead of reduced tillage with crop residue application led to a higher maize yield in both baseline and future warmer scenarios.…”

“…The stronger effect of reduced tillage on maize yield at St3 (Haplic Lixisol at footslope) could be explained by the fact that Dassari is rather a sub-humid site, the improved fertility status of the soil (soil organic carbon) and higher simulated daily average available soil water during the growing season compared to St4 at the upslope. In agreement with the results from Fuentes et al (2003), Wang et al (2019), andXu et al (2019), improved maize yield could be attributed to higher soil nutrient stocks, soil organic carbon and improved NUE of maize crop under the reduced tillage system, which was also observed during the field experiment in this site (Nafi et al, 2020(Nafi et al, , 2019.

Dynamics of Growth and Nitrogen Capture in Winter Oilseed Rape Hybrid and Line Cultivars under Contrasting N Supply

“…One reason for this is that on-farm monitoring of these processes requires frequent sampling, which could be time consuming and not practical. In contrast, the simulation of crop growth dynamics is effective and provides the possibility to explicitly explore these key processes [25,26].…”

“…Considerable efforts have been made to describe and predict crop growth process using various crop models, such as SPACSYS [26][27][28], DNDC [29,30] and DSSAT [31,32]. However, the operation of these models requires various parameters and high level of expertise to appropriate result interpretation.…”

Mapping green technologies literature published between 1995 and 2019: a scientometric review from the perspective of the manufacturing industry

“…The leading cause of industrial pollution is the use of traditional technologies, for the production processes (Martins et al 2018 ), which not only negatively affect the environment but also put forth social and economic costs to society. Moreover, there is also an enormous pressure on researchers for conducting promising research on GT, in order to mitigate the adverse effects of traditional technology on the environment (Wang et al 2019 ). In this review article, the authors mainly focus on GTs or environmental technologies, which are believed to possess the potential to reduce the negative impact on the environment.…”
