Land use is characterized by the arrangements, activities and inputs people undertake in a certain land cover type to produce, change or maintain it. Changes in land use cover also have a drastic effect on chemical and biological properties of soil and hence change the quality of the soil. A study was conducted to examine the effect of land use types on soil physical and chemical properties within an Alfisol in the arboretum of Forestry Research Institute of Nigeria (FRIN). Soil samples were collected at two soil depths (0-15cm and 15-30 cm soil depths) under these plantations: Nauclea diderrichii (NP), Gmelina arborea (GP), Terminalia superba (TP), Arable crop land (AC) and a Fallowed Land (FL) and were analysed for some selected soil physical and chemical properties. The experiment was a completely randomize design (CRD) with six replications. Data collected was subjected to Analysis of Variance (ANOVA) and means were separated using Duncan Multiple Range Test (DMRT). Results revealed that higher content of clay was recorded in 0 to 15 cm depth of both GP (15.00%) and FL (15.00%) plantation lands whereas higher clay content was recorded at 15 to 30 cm depth in Arable crop land (23.00%) and Nauclea plantation land (21.00%). Higher total nitrogen (TN) was observed in FL (1.44%)  while  TN availability decreases in the order AC>GP>NP>TP. Higher values of soil Organic Carbon (16.74%), Available phosphorus (2.15 Cmol/kg)  and Organic matter (28.86%) were obtained under FL as compared to the other land use fields at 0 to 15 cm depth. Bulk density and porosity were highly variable among different land use types and ranged from (1.039 - 1.415) g cm−3 and (17.99 - 48.87)%. The information generated from the present study suggested fallowed land use as the best land use system because of its higher soil organic matter management, as it improves the soil structure and this will assist in developing sustainable and ecologically stable land use management strategies for the study area.

The diversity and community distribution of soil bacteria in different land use types in Yangtze River Basin, Chongqing Municipality were studied by using Illumina MiSeq analysis methods. Soil physical and chemical properties were determined, and correlation analyses were performed to identify the key factors affecting bacterial numbers and α-diversity in these soils. The results showed that the soil physical and chemical properties of different land use types decrease in the order: mixed forest (M2) > pure forest (P1) > grassland (G3) > bare land (B4). There were significant differences in bacterial diversity and communities of different land use types. The diversity of different land use types showed the same sequence with the soil physical and chemical properties. The abundance and diversity of bacterial in M2 and P1 soils was significantly higher than that in G3 and B4 soils. At phylum level, G3 and B4 soils were rich in only Proteobacteria and Actinobacteria, whereas M2 and P1 soils were rich in Proteobacteria, Actinobacteria and Firmicutes. At genus level, Faecalibacterium and Agathobacter were the most abundant populations in M2 soil and were not found in other soils. Pearson correlation analysis showed that soil moisture content, pH, AN, AP, AK and soil enzyme activity were significantly related to bacterial numbers, diversity and community distribution.

Basaltic soil is considered as the most advantageous soil unit in comparison with other units of the Central Highlands, that distributed mainly in the plateaus of Kon Plong, Kon Ha Nung, Pleiku, Buon Ma Thuot, M'Drak, Dak Nong and Di  Linh - Bao Loc. Much of the basaltic soil in the Central Highlands has been used for cultivation of long-term industrial crops. Currently, due to massive forest destruction for developing long-term industrial trees in the basaltic soil in Bao Loc - Di Linh, the natural fertility of the basaltic soil has been remarkably reduced. The physical and chemical properties of the basaltic soil under different land use types have decreased sharply compared to basaltic soil under the natural forest. The average rate of decline of total organic matter content of plantation forest land is 16%, overused forest land is 44%, tea land is 46%, coffee land is 60% compared to the same soil unit under the natural forest. The cation exchange capacity (CEC), content of total nutrients and plant available nutrients under the land use types were also decreased significantly compared to the soil unit under the natural forest. The changes of physical and chemical properties of the basaltic soil with coffee cultivation was highest in comparison with other land use types. The organic matter and potassium are two limiting factors of the nutrients in the basaltic soil of the study area, especially for tea cultivation.

AbstractWe assessed the effect of different land use types on the physical and chemical properties of soil. We analysed three cases. Nine soil samples were taken at different depths (0–10, 10–20 and 20–30 cm) from three locations, namely, sawmill, dumpsite and market. Analyses were carried out to determine the influences on the physical and chemical properties of the soil. All the land types had considerably high sand contents, with minor silt and clay. Available phosphorus and the exchangeable bases were significantly (p ≤ 0.05) affected by land use and soil depth. Moisture content (p ≤ 0.05) was significantly affected by land use, while bulk density (p ≤ 0.01) was significantly affected by soil depth. Soil organic matter and carbon were also generally low in all three locations. Consequently, ameliorative land management practices have to be adopted to prevent nutrient loss and land degradation.

The impoundment of dams can significantly alter shorelines, hydrological regime, sediment and nutrient cycle. With the completion of Chushandian reservoir dam, land use types around the reservoir have been profoundly affected by flooding. As yet, the characteristics of soil properties on different land use types in new built reservoir have not been fully elaborated. In this work, we investigated the variation of soil physical and chemical properties at distance scale for different land use types after short-term inundating. Soil physical properties, chemical properties, soil particle structure were determined. This study reported that short-term inundating had impacts on soil physical and chemical properties of different land use types. Our results indicated that the soil physical and chemical properties at 0 m site of each land use types may be mainly affected by the nutrient status of overlying water. The soil TN, TC of all land use types decreased gradually with the increase of distance from river bank, among which the contents of TN and TC at W2 were significantly higher than those at other sites. Compared with woodland, both abandoned cropland and grass land showed the phenomenon of soil particle loss and nutrient leaching. The characteristics of low NH4-N and high NO3-N were observed in the woodland after flooding, which may be related to denitrification. The main influencing factor is soil microbial activity at W20. The main influencing factor is soil nutrient status At W2. And at abandoned cropland and grassland, the main influencing factor is soil physical properties. The response of different land use types to short-term flooding may be mainly related to the degree of vegetation coverage. Abandoned cropland showed stronger resilience, while grassland showed stronger tolerance. The present study suggested that early and timing restoration will be an effective way to repair the riparian habitat.

Crop-livestock integration represents an interesting alternative of soil management, especially in regions where the maintenance of cover crops in no-tillage systems is difficult. The objective of this study was to evaluate soil physical and chemical properties, based on the hypothesis that a well-managed crop-livestock integration system improves the soil quality and stabilizes the system. The experiment was set up in a completely randomized design, with five replications. The treatments were arranged in a 6 x 4 factorial design, to assess five crop rotation systems in crop-livestock integration, and native forest as reference of soil undisturbed by agriculture, in four layers (0.0-0.05; 0.05-0.10; 0.10-0.15 and 0.15-0.20 m). The crop rotation systems in crop-livestock integration promoted changes in soil physical and chemical properties and the effects of the different systems were mainly detected in the surface layer. The crops in integrated crop-livestock systems allowed the maintenance of soil carbon at levels equal to those of the native forest, proving the efficiency of these systems in terms of soil conservation. The systems influenced the environmental stability positively; the soil quality indicator mineral-associated organic matter was best related to aggregate stability.
