Effects of soil physical properties on erodibility and infiltration parameters of selected areas in Gidan Kwano

Abstract

This study looked at the physical properties of soil of selected areas of Gidan Kwano campus of Federal University of Technology Minna, Nigeria and their effects on erodibility and infiltration parameters. Infiltration rate of the selected areas were conducted using a double ring infiltrometer and soil samples collected at different depths of 0-30 and 30-60 cm respectively. Collected samples were analyzed to determine physical properties such as moisture content, particles size, bulk density, porosity and organic matter. Textural classification was carried out to determine the percentage dominance of the various soil types present in the selected areas. Plot A has a steady infiltration rate after hour at 0 cm/hr. While plot B had a steady infiltration rate after 30 minutes at 1cm/hr. The soil moisture count for plot A ranged between 9.54% to 14.56% while that of plot B range between 10.64% to 11.26%. The particle sizes analysis indicated that the soil type in plot A is mainly medium loam and predominantly sand clay loam in plot B. It is therefore concluded that, the study area is susceptible to erosion because of poor infiltration rate.

Delineation of a Groundwater Potential Zone Map for the Kızılırmak Delta by Using Remote-Sensing-Based Geospatial and Analytical Hierarchy Processes

“…Soil texture (grain form, size, permeability, etc.) substantially impacts groundwater movement [65]. Coarse-grained soils have a high infiltration potential and provide higher groundwater recharge than fine-grained soils [66].…”

Assessing the role of soil engineering properties in gully development and enlargement in southeast Nigeria using geostatistical and novel indexical techniques

“…Infiltration of water into the soil and its movement therein strongly affect how the soil will behave under the shear stress induced by rainfall (Musa et al 2017;Egbueri and Igwe 2020). The water infiltration and movement capacities are determined by the soil porosity and soil permeability, respectively.…”

“…Nevertheless, erodibility factor was also calculated for the gullies, to further verify and possibly validate this assertion. The erodibility factor (K) is a mathematic model that also gives a quantitative description of a soil's inherent erodibility, providing insights into the susceptibility of the soil to detachment and transportation by rainfall and surface runoff (Mulumba and Lal 2008;Isikwue et al 2012;Musa et al 2017). Moreover, this is index reflects the possible rates at which different soils would erode under the same environmental conditions (Musa et al 2017).…”

Sifat Fisik Tanah dan Hubungannya dengan Kapasitas Infiltrasi DAS Tamiang

“…Kuantifikasi limpasan diprediksi dari besaran curah hujan dikurangi kapasitas infiltrasi (Dooge 1973;Singh 1995). Kapasitas infiltrasi dipengaruhi penggunaan lahan, vegetasi dan parameter fisik tanah (Agustina et al 2012;Sajjadi et al 2016;Musa et al 2017). Parameter fisik tanah yang sangat berperan penting dalam kapasitas infiltrasi adalah tekstur tanah, berat jenis, kadar air, permeabilitas dan porositas (Sun et al 2018;Roy and Bhalla 2017;Wohl et al 2012;Young 1988;Black 1965;Foth 1987).…”
