Abstract: Morphological features and Physico-Chemical Properties of twenty surface soils derived from five varied parent materials in Cross Rivers Sate, Nigeria were evaluated in relation to probable constraints to increase crop yields. Four replicate soil samples were collected from the top 15cm depth of each parent material for laboratory analyses using standard methods. Results showed that the colour notations, structure and texture of the soils were similar within Same Parent materials but varied widely across the locations. The particle size distribution showed that shale derived soils are finer in texture than those of other parent materials. Chemically, the soils are low in Plant........

Abstract: Organic matter occurrence in the soilcauses many problems for the engineering projects. In this study, seventeen locations have been chosen from Basrah soils with sampling frequency one sample per meter. For the experimental tests, Grain-size, Atterberg limits, and organic matter tests were performed on all the samples to evaluate the spatial distribution of the organic matter at selected areas in Basrah governorate. The results show that 62.3% of samples are classified as low plasticity clayey silt (CL), 27% as low plasticity silty clay (ML) and low plasticity organic soils ........

Abstract: The precipitation of atmospheric water vapour to the liquid or solid phase is accountable for clouds, rainfall and snow, which plays important role in climate and climate change. The energy released during vapor condensation affects the dynamics of the atmosphere. Through this interaction, the vertical stability of the atmosphere is modified, influencing the weather systems and their associated precipitation patterns. In this paper, we derived the total water vapour content in atmosphere using radiosonde observation over the Chennai radiosonde station (VOMM) for 44 years (1974-2017). The paper also highlights the statistical analysis of total water vapour content. The trend of total water vapour content in atmosphere is useful to understand the climate and its change in atmospheric conditions............
