ABSTRACT- The present research was conducted to study K forms and fixation in soils of southern Iran (Hormozgan Province) with aridic and aridic-ustic regimes and to address the relations between soil mineralogy and potassium forms. Thirteen surface soil samples (0-25 cm) were collected from different regions and analyzed in laboratory. Illite and feldspar and mica are the major clay and soil m...

Abstract Encountering weak fine-grained soil presents a significant challenge during highway construction. The conventional approach to address this involves incorporating calcium-based stabilizers, particularly cement, for stabilization. However, despite its widespread use, the application of cement stabilization has adverse environmental consequences. Accordingly, finding alternative methods ...

Cytokinins may reflect soil water status and regulate rice (Oryza sativa L.) grain filling. This study investigated the changes in cytokinin levels in rice plants and their relations with grain filling under alternate wetting and drying irrigation. Two 'super' rice cultivars were field grown. Three irrigation regimes, alternate wetting and moderate soil drying (WMD), alternate wetting and sever...

Tillage operations disrupt surface layers of agricultural soils, creating a loosened structure with a substantial proportion of interaggregate porosity that enhances liquid and gaseous exchange properties favorable for plant growth. Unfortunately, such desirable soil tilth is structurally unstable and is susceptible to change by subsequent wetting and drying processes and other mechanical stres...

Soil physical properties are the main factors that influence soil fertility and directly affect structure water storage capacity. Microplastics (MPs), which have caused growing concern with respect to pollution, readily been detected in cultivated soils. However, current data regarding effects of MPs on during wetting–drying cycles remain insufficient. Therefore, we aimed explore different MP p...

Reinforced concrete structures are now widely used in China, and with the exploitation of marine resources, many a relatively harsh service environment. Concrete wave tidal stream areas is dry wet cycle state. When unsaturated state, chloride ions will invade by diffusion convection, which accelerates erosion reinforcement within degrades performance. Therefore, study ion under cycles particula...
