“…Table 4 shows the results of evaluation of correlation analysis or multiple linear regression within cutting regime. Moderate negative dependencies of ρ z and ρ d on SOM (correlation coefficients r = -0.35 to -0.68) were observed (similarly Evrendilek et al 2004;Kaleem Abbasi et al 2007), which are also shown in Figures 5 and 6. Similar results were obtained for dependence of ρ d on P n (r = -0.38 to -0.63, also Figure 7).…”

“…Eynard et al (2006) found a positive correlation of porosity with the soil organic carbon content in PGA. Evrendilek et al (2004) found out that the content of soil organic carbon was positively correlated with available water capacity and the overall P and negatively correlated with ρ d . Similarly Kaleem Abbasi et al (2007) established an indirect dependence of ρ d on the content of humus in the soil of grass and forest covers and in arable land with determination coefficient R 2 = 0.75.…”

Changes of selected soil physical properties (porosity P, soil organic matter SOM, bulk density ρ d , particle density ρ z , characteristics of water retention capacity -maximum capillary water capacity θ CMC , and non-capillary porosity P n ) of permanent grassland (wet, non-fertilized, thistle meadows ass. Angelico-Cirsietum palustris, crystalline complex area, Czech Republic) in the top soil layer (3-10 cm) managed under three regimes (uncut UC; cut once a year C1; cut twice a year C2) were monitored for one undrained and two drained sites. There were no significant differences in selected soil physical properties among the test plots at the beginning of the study. As the intensity of utilisation decreased, the values of P, SOM, and P n increased and ρ d , ρ z and θ CMC decreased. Within 5-10 years of the beginning of the study, average values were: P at UC = 70, C1 = 69, C2 = 67%; SOM at UC = 10.7, C1 = 10.6, C2 = 10.0%; ρ d at UC = 0.76, C1 = 0.79, C2 = 0.84 g/cm 3 ; ρ z at UC = 2.53, C1 = 2.55, C2 = 2.56 g/cm 3 ; θ CMC at UC = 50, C1 = 53, C2 = 51%; P n at UC = 21, C1 and C2 = 16%. Moderate negative dependence of both ρ z and ρ d on SOM and of ρ d on P n and a moderate positive dependence of P on SOM was observed. θ CMC changes did not show links to other soil physical properties. The greatest looseness of the top soil layer, expressed by a decrease in ρ d , occurred with the UC regime in direct correlation with SOM, P n and P.

“…The grassland had lower bulk density than the cultivated land which could be due to restricted grazing at the grassland to harvest fodder and free grazing on crop lands after harvest and continuous ploughing at the same depth of cultivated lands. Evrendilek et al (2004) also reported that conversion of grassland into cultivated land during a 12-year period increased BD by 10.5% but decreased TP by 9.1%. Moreover, in uncultivated land, there was relatively higher organic matter (OM) making the soil loose, porous and well-aggregated that might have reduced the BD.…”

“…The conversion of forest ecosystem to other forms of land cover may decrease the stock of OC due to changes in soil moisture and temperature regimes, and succession of plant species with differences in quantity and quality of biomass returned to the soil (Offiong & Iwara, 2012). Evrendilek et al (2004) showed that deforestation and subsequent cultivation decreased organic matter by 48.8%. Moreover, the conversion of forest into cropland is known to deteriorate soil physical properties and making the land more susceptible to erosion since macro-aggregates are disturbed (Çelik, 2005).…”

Information about effects of different land use systems on soil physico-chemical properties is crucial for best land management practices. This study was, therefore, conducted to evaluate the same on Nitosols of Achefer District, Northwestern Ethiopia. The landuse systems studied included grassland, cultivated land, plantation forest and natural forest. The research was superimposed on land use systems that were located nearby on similar soil, contour line and slope classes. Undisturbed core and disturbed composite soil samples were collected randomly from two sites with three replications for each landuse system at two varying depths (0-15 cm and 15-30 cm). The undisturbed soil samples were analysed for bulk density, particle density, porosity and moisture content at different pressures; while the composite soil samples were analyzed for pH, organic carbon, total N and available P. Results of the study indicated that the lowest bulk and particle densities, the highest total porosity, and higher moisture content at both field capacity and permanent wilting percentage were found under natural forest land use system. In contrast, the highest bulk and particle densities, the lowest total porosity and lower water contents at both field capacity and permanent wilting percentage were obtained under the cultivated landuse system. Soil pH was moderately acidic under all landuse systems. The lowest organic carbon, total N, and C:N ratio were recorded under cultivated land; whereas the highest values of the same parameters were found under natural forest. In all landuse systems, organic carbon and total N decreased with soil depth. The highest and lowest available P contents were recorded under natural forest and grassland, respectively. From the results of the study it was possible to conclude that conversion of forest lands to cultivated and grasslands had detrimental effects on the soil physico-chemical properties under subsistance farming systems of the study area. It is, therefore, recommended that appropriate and integrated land management options for different land use syetems are required to sustain agricultural productivity while protecting the environment.

“…Bulk density might be related to the presence of organic matter and clay content (Evrendilek et al 2004), soil aggregate stability and porosity (Yan et al 2009). The bulk density of soils in all land uses increased with depth (Table 3) could be at-tributed to the greater compaction in the lower depths of the soils under study with time.…”

In this study, we investigated the effects of three land uses on soil properties in two soil layers; surface soil (0∼15 cm) and subsoil (15∼30 cm). Soil samples were collected from planted forest, barren lands and cultivated lands from different areas in Chittagong Cox's Bazar and analyzed for some physical and chemical properties. Results showed that soil textural class varied from sandy clay loam in planted forest and barren land site to sandy loam in cultivated soils. Maximum water holding capacity was higher in forest followed by barren land and the lowest in cultivated lands. At both soil depths, soils of cultivated land showed the highest values of bulk density (1.42 to 1.50 g cm -3), followed by barren lands (1.37 to 1.46 g cm -3) and the least (1.32 to 1.45 g cm -3) in forest soils. Total porosity decreased with depth ranging from 40.24% to 41.53% in subsoils and from 42.04 to 43.23% in surface soil of cultivated and of planted forest sites respectively. The result further revealed that organic carbon (OC) and total nitrogen (TN) contents were higher in the planted forest soil than in other two land uses. The soils of all land uses under study are acidic in nature and the lowest pH was found in both surface and subsoils of barren land. Cultivated soil contained the highest amount of available P, Ca, Mg and K in both surface soil and subsoils. In contrast, barren site had the lowest contents of available P, Ca, Mg and K in both layers. The soil organic carbon (SOC) and total N storage were higher in planted forest than in barren and cultivated land uses.
