Abstract We show through laboratory experiments that the self-patterning of a thin clayey layer can be triggered by condensation. The natural sediment used in was highly polydisperse granular paste with smectite clay fine fraction. Under certain physicochemical conditions, condensation induces solid-to-liquid transition layer, resulting flow and formation band structures. These results suggest ...

Studies on clayey soils developed in temperate areas have shown that their water retention properties are related to both the clay content and specific pore volume of clay, latter being hydric history soil, is drying/wetting cycles. Our objective was discuss validity these results for semi-arid areas. Samples were collected located Syria. Physico-chemical determined. Water measured at field cap...

Understanding the effects of external organic and inorganic components on soil fertility and quality is essential for improving low-yielding soils. We conducted a field study over two consecutive rice growing seasons to investigate the effect of applying chemical fertilizer (NPK), NPK plus green manure (NPKG), NPK plus pig manure (NPKM), and NPK plus straw (NPKS) on the soil nutrient status, en...
