The multi-scale microstructure of a lotus leaf is rendered non-wetting by micro-protrusions and nano-hairs present on its surface. The mechanical properties of the surface become important since the water droplet has to be supported on the micro-protrusions without wetting the surface. Current work correlates the non-wetting behavior of the lotus leaf with its mechanical properties (Young's mod...

In the rice growing area of Kenya’s highlands, development a water-saving cultivation system is key strategy because shortage irrigation water frequently occurring problem. The purpose this study was to investigate effect alternate wetting and drying (AWD) on growth yield under unique environment tropical highlands. Field experiments were performed over period four years (2014–2017) in paddy fi...

Wetting phenomena plays an interesting role in the technological development of materials. Recently, much attention has been directed to the study of magnetic solid films. To understand, theoretically, the effect of surface on wetting and layering transitions in these systems, we will give in this chapter a presentation of several relevant recent theoretical works realized on wetting and layeri...

A pot experiment was executed to investigate the impact of biochar and compost with water-saving irrigation on rice yield, water use efficiency, physicochemical properties soil. Two regimes—namely alternate wetting drying (AWD) continuous flooding (CF)—and four types organic amendments (OA)—namely husk (RHB), oil palm empty fruit bunch (EFBB), a control—were applied evaluate their effects. Unde...

The initial soil water content affects wetting front instability. A series of experiments were conducted where water was infiltrated into a 20/30 sand with initial volumetric water contents of 0, 0.005, 0.01, 0.015, 0.02, 0.03, 0.04 and 0.047 cm/cm. Both water content and matric potential were measured. Water content was measured with Synchrotron X-rays at the Cornell High Energy Synchrotron So...
