Lunar soils gradually become mature when they are exposed to a space environment, and nanophase metallic iron (npFe0) generates within them. npFe0 significantly changes the optical properties of lunar soils and affects the interpretation of the remotely sensed data of the lunar surface.

AbstractFine-grained sediments are a major parent material in Ebro Valley soils. During the 1960s, the area was transformed by irrigation and soils underwent serious degradation processes. The sediments have a fine texture, high CaCO3 contents and high salinity-sodicity levels, and contain illite as the most important phyllosilicate in the fine fractions. Two groups of finely laminated organization have been recognized in terms of layer thickness and grain-size distribution. Based on texture, the microstructure of the silty and clayey layers is different, irrespective of their mode of formatio

Abstract:

The world is dealing with both agrarian and nutritional issues. We must concentrate on dry lands in order to further increase grain production because agricultural lands with irrigation facilities have been fully utilised. It is difficult to use dry lands to produce enough high-quality grains because of their low fertility. Millets, a crop that complies with climate change regulations, outperform other grains like wheat and rice in terms of poor growing conditions and high nutritional value. Sustainable food systems aim to provide sufficient and nutritious food, while maximising climate resili
