Biochar application can enhance soil health and alter bacterial community structure. However, knowledge relating to biochar on nutrients of mountainous apple orchards then assessing its effect health, especially microorganisms, is still scanty. Therefore, we evaluated the responses six treatments [Ck (0), T1 (2), T2 (4), T3 (6), T4 (8), T5 (10) Mg hm-2] with a basal dose chemical fertilizer under potted trees across 3, 6, 9, 12 months, investigated rhizobacterial communities. Experimental...

Changes in the soil organic matter are related to land-use change of sustainable agricultural production. However, few studies have been reported on effects changes planting practices SOC during reconstruction period old apple orchards. In this study, 4 treatments were applied orchards (more than 20 years old) Loess Plateau: thinning and replanted saplings (TR); all felled planted corn (CR); millet (MT); potato (PT). It was found that: ranked as MT > PT CR TR, decreased with depth,...

The Loess Hilly–Gully region (LHGR) is the most serious soil erosion area in world. For small watershed with high management this area, scientific problem that has been paid attention to recent years impact of land consolidation project on environment gully region. In study, 3D simulation method vegetation, eroded sediment and pollutant transport was innovated based principles dynamics similarity theory, impacts GLCP were analyzed at different scales. verification results show design scale...

Gully Land Consolidation (GLC) is a proven method to create farmlands and increase crop yields in the Loess Hilly Region, China. However, GLC influences phreatic water transformation might cause disasters, such as salinization swamping. For exploring influence of on mitigating series indoor experiments were conducted artificial rainfall hall. Then, we simulated patterns under more conditions with HYDRUS-3D. Finally, an engineering demonstration field was performed validate our research. The...

Flooding, a common environmental hazard worldwide has in recent times, increased as result of climate change and urbanization with the effects felt more developing countries. As result, explosive flooding to Tenaga Nasional Berhad (TNB) substation is rapidly due existing substations are located flood prone area. By understanding impact their substation, TNB provided non-structure mitigation integration Flood Hazard Map substation. Hydrology analysis important part providing runoff input for...

Viscosity is a fundamental hydrodynamic property of erosive flow, but except for the effect sediment on viscosity, other substances such as agricultural nitrogen characteristics flow has rarely been studied. This in turn likely to be an important factor affecting transport mechanism. In this study, viscosity sediment-laden with different levels was investigated by using self-made dual vertical tube rheometer. It found that: (i) coefficient (μ) nitrogen-bearing affected concentration,...

Abstract Indonesia identifies as climate change hotspots and indicates to have increasing hydrological drought risk. The impact of is easier analyze because only using river discharge directly affects by rain, which requires a long process time. can be minimized Disaster Risk Management (DRM) cycle. In this study, Standardized Runoff Index (SRI) was used quantitative index for the occurrence reference phase in DRM. This study consists 3 parts: projecting monthly until year 2045 ensemble...
