Living plant roots modify both mechanical and hydrological characteristics of the soil matrix (e.g. soil aggregate stability by root exudates, soil cohesion, infiltration rate, soil moisture content, soil organic matter) and negatively influence the soil erodibility.
This investigation included field procedures such as drilling boreholes and taking soil samples, measuring the soil moisture content, soil suction, and also excavating trenches to observe the distribution of tree roots under the ground.
A significant interaction effect of the rehabilitation system and slope aspect was observed for residual soil moisture content, soil organic C (SOC) content, SOC stock, size distribution of aggregates and C content in aggregate fractions.
Terraces have been found to improve soil physico-chemical properties such as soil moisture content, soil hydraulic conductivity, soil organic carbon, nitrogen, phosphorus, and potassium (Ruto 2015).
Soil moisture content, soil organic carbon (SOC), available phosphorus, available potassium, total nitrogen (TN), the ratio of SOC TN (C/N), Pb, and Cu increased notably from suburbs to the urban core, while soil pH, bulk density, TN, Cr, Ni, and Mn were not significantly different across urbanization levels.
Thirty-two additional cores (with identical treatments to those used for measuring GHG emissions) were destructively sampled, immediately after amendment addition, and analysed for gravimetric soil moisture content, soil mineral N content (N-NH4+ and N-NO3−) and WSOC.
Specifically, we analyzed the soil moisture content (SMC), soil pH, soil BD, total nitrogen (TN) content, SOC TN (C/N), SOC, available phosphorus (AP), available potassium (AK), and heavy metals (Pb, Cr, Cu, Ni, Mn).
The role of lateral and vertical redistribution of soil moisture in water conservation will be discussed based on the analysis of soil moisture retention characteristics, temporal variation in soil moisture content and soil moisture patterns.
Future research should focus on the impact of canopy management on soil moisture content and soil evaporation and transpiration.
So, it is concluded that the vertical equivalent damping ratio of tire soil system is evidently dependent on tire inflation pressure, soil moisture content and soil depth.
The input parameters of the network were width of cut, depth of operation, speed of operation, soil moisture content and soil bulk density.
