Abstract Aseismic megathrust slip downdip of the seismogenic zone is accommodated by either steady creep or episodic slow events (SSEs). However, geological conditions defining rheology remain elusive. We examined exhumed subduction mélanges on Kyushu, Japan, which deformed at ∼370–500°C under greenschist to epidote‐amphibolite facies conditions, comparable warm‐slab environments. The recorded ...

Abstract The upper mantle is heterogeneous in Fe isotope compositions, but the origin of heterogeneity needs understanding. Recent studies on oceanic basalts demonstrate that results from low‐degree melt metasomatism. However, whether this hypothesis global significance testing continental settings. Here we present an isotopic study intraplate alkali China, which are shown to have derived conta...

Afforestation, settled before 60–90 years and adjacent solonetzic grasslands, representing the natural vegetation cover were compared in this study based on their basic soil characteristics (pH, CaCO3 content, organic carbon (SOC), exchangeable sodium percentage (ESP)) up to 2 m depth. The assumption was that plantings of arbour can change sodic soils not only superficial layers but even larger...

Sodicity affects a larger area than salinity, but research on the sodicity tolerance mechanism is limited. The study was carried out to screen 120 finger millet genotypes under sodic soil conditions and identify sodicity-tolerant genotypes. experimental field were sandy clay loam with pH 8.9, electrical conductivity (EC) 0.94 dSm-1 exchangeable sodium percentage (ESP) 21.5, which naturally sodi...

The main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (SOM) and lowavailability of macro and micro-nutrients. The effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (USWCS) on the chemical properties of a saline-sodic soil was investigated. The experimentwas conducted using a randomized complete block des...

Many avocado growers are debating the question of whether or not to apply calcium to their groves. Some advocates say calcium is a necessary soil additive, creating almost magical improvements in soil chemical balance and tree growth. Others maintain that, since calcium is common in California soils, it serves only to improve soil structure in sodic soils or soils with permeability problems due...

Soil salinity is a key abiotic stressor that negatively impacts plant growth and restricts land use by causing degradation (Gamalero, et al. [1]). Saline sodic soils are characterized their high soluble salt content pH, respectively, which result in imbalances nutrient cycling reduced organic content, carbon stocks, microbial activity the soil [3].
