Aims Straw checkerboard barrier technology, as a sustainable and environment-friendly method, is intended for erosion control, plant recovery at endangered areas. Finding how soil chemical properties and water status alters and how pilot cover plants respond are vital for extra management actions. Methods In order to study soil characteristic and growth performance of winter cover crops, an experiment was carried out in 2018. Checkerboards were setup in a 1×1 m pattern with rice residues. Seeds of Onobrychis sativa, Secale montanum and Agropyron sp were sown at the checkerboards and bare ground as the control. Detailed analyses were carried out on the physiological responses and the related soil properties during the growing season in borders and centers of the straw checkerboards and bare ground. Results Soil covered with straw checkerboard barriers was more effective for improving vegetation growth, established taller plants with higher biomass. Based on the physiological analyses, the rye grown in a straw checkerboard coped well with dry conditions. Higher proline content and more efficient osmotic adjustment indicate improvements of soil water retention status, which may alleviate drought stress damages and improve cover crop performance in straw checkerboard plots. Photosynthetic pigments also showed higher contents in these conditions for rye. Soil organic matter, total nitrogen, available phosphorus and potassium and water storage increased in checkerboards too; however, such effects vary with the crop type. Conclusions This technique could be deemed as an effective management strategy in semi-arid areas and an important method for conserving natural resources and sustaining productivity.

Aims Finding how straw checkerboard barrier technology, as a sustainable and environment-friendly method, may affect soil chemical properties and water status despite wind erosion control directed us to evaluate this technique as a vital component of management plans in sloping lands of semi-arid areas. We were interested to know if it could support the soil capabilities to grow pilot plants and recover some ecological services via alleviate drought stress or amendment of soil attributes.Methods In order to study soil characteristic and growth performance of winter cover crops, an experiment was carried out in 2018. Checkerboards were setup in a 1×1 m pattern with rice residues. Seeds of sainfoin (Onobrychis sativa), rye (Secale montanum) and tall wheatgrass (Agropyron sp) were sown at the checkerboards and bare ground as the control. Detailed analyses include growth characteristics, physiological attributes i.e. photosynthetic pigment contents, proline and malondialdehyde contents and relative water contents of mentioned crops and the related soil properties during the growing season were carried out in borders and centers of the straw checkerboards and bare ground.Results Soil covered with straw checkerboard barriers was the most effective for improving vegetation growth and establishing taller plants with higher biomass. Based on the physiological analyses, the rye grown in straw checkerboard plots coped well with dry conditions. Higher proline content and more efficient osmotic adjustment indicates improvements of soil water retention status, which may alleviate drought stress damages and improve cover crop performance in straw checkerboard plots.

“…Correlation analysis in our study acquired distinct results, especially the positive correlation between soil quality and roots activity, and the positive correlation between RIF, RBA and LAI, AGBA. Moisture conservation, improvement in soil fertility and lentil production achieved in a short duration lentil variety under reduced tillage practice in drought stress condition ( Das et al, 2019 ). However, the effects of smash-ridging on soil enzyme activity, soil microbial community, soil nutrient use efficiency, and grain quality under smash-ridging need further research.…”

The practice of smash-ridging on dry land crop cultivation has shown much promise. However, the mechanism how does soil functionality and root traits can affect rice yield under smash ridge tillage with reduced nitrogen fertilization have not yet been explored. To fill this knowledge gap, we used three tillage methods—smash-ridging 40 cm (S40), smash-ridging 20 cm (S20), and traditional turn-over plowing 20 cm (T)—and two rice varieties (hybrid rice and conventional rice) and measured soil quality, root traits, rice yield and their correlation analysis at different growth stages. Soil physical and chemical properties were significantly improved by smash-ridging, including improvements in root morphological and physiological traits during three growth stages compared with T. S40 had the highest leaf area index (LAI), plant height (PH), and biomass accumulation (BA). Increment in biomass and panicle number (PN) resulted in higher grain yield (GY) of 6.9–9.4% compared with T. Correlation analysis revealed that root total absorption area (RTAA), root active absorption area (RAA), and root area ratio (RAR) were strongly correlated with soil quality. Root injury flow (RIF) and root biomass accumulation (RBA) were strongly correlated with LAI and above-ground plant biomass accumulation (AGBA). Conclusively, S40 is a promising option for improving soil quality, root traits, and consequently GY.
