Soil reaction is an important issue that adversely affects soil fertility and crop productivity. Twenty five representative soil samples from farmers’ fields of Ramchandrakura, Bishgiripar, Andharupara and Nayabil villages of Nalitabari upazila under Sherpur district (AEZ 22-Northern and Eastern Piedmont Plains) and twenty soil samples from farmers’ fields of Bakta, Nishchintopur, Boril and Kaladaho villages of Fulbaria upazila under Mymensingh district (AEZ 28-Madhupur Tract) were collected and analyzed to study the physico-chemical properties of acid soils. Among 45 samples, 13 were sandy loam, 17 were silt loam, 10 were loam, 2 were clay loam and 3 were loamy sand in texture. Soil pH was very strongly acidic to strongly acidic. The soil pH of AEZ 22 varied from 3.81 to 4.78 and that of AEZ 28 varied from 3.96 to 5.11. The organic C of Nalitabari soil varied from 0.50 to 1.35% and that of Fulbaria soils ranged from 0.50 to 1.27% showing low to medium status. The status of nutrient elements viz. N, P, K and S in most of the samples was very low or very low to medium. Total N contents of AEZ 22 varied from 0.06 to 0.14% and that of AEZ 28 varied from 0.07 to 0.16%. Available P in soils of AEZ 22 varied from 3.25 to 26.45 ppm and that in soils of AEZ 28 ranged from 2.45 to 16.62 ppm. Exchangeable K in AEZ 22 soils varied from 15.13 to 92.41 ppm and that in AEZ 28 soils varied from 16.09 to 98.41 ppm. Available S in AEZ 22 soils varied from 1.68 to 33.70 ppm and that in AEZ 28 soils from 3.95 to 27.52 ppm. Therefore, these acid soils should be amended with liming materials and fertilized with inorganic fertilizers and organic manures for successful crop production. Asian J. Med. Biol. Res.

Soil physico-chemical properties are an important phenomenon for sustainable crop production and maintenance of optimum soil health. Hence, a laboratory measurement was conducted with soil samples of three years long experimental field of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh to assess the changes in five selected soil physico-chemical properties viz. soil texture, bulk density, soil pH, total nitrogen and organic matter. The experiment was laid out in a split plot design with two water regimes (continuous flooding and alternate wetting & drying) in the main plots and five fertilizer treatments (N0 - control, N1- 140 kg N/ha as PU, N2- 104 kg N/ha as USG (2× 1.8 g/ 4 hills), N3 - 5 t CD + PU @ 140 kg N /ha on IPNS basis and N4- 5 t CD + USG (2× 1.8 g/ 4 hills @ 104 kg N/ha)) in the subplots under rice-rice cropping pattern with three replications. After three years, soil samples were collected at 0-5 and 5-10 cm soil depths for measuring bulk density and at 0-10 cm depth for other soil properties and analyzed. Results found that % sand, % silt, % clay, bulk density and soil pH was not changed significantly compared to initial status. Percentage of total nitrogen and organic matter was significantly affected by irrigation and fertilization. Total nitrogen (%) was higher in AWD whereas organic matter (%) was higher in CF practice. The highest total nitrogen (%) and organic matter (%) was found in N4 treatment in which USG was applied in combination with cowdung as organic manure. It can be suggested that N4 treatment was formed good combination for sustaining chemical properties of soil. Further long- term experimentation will be needed to know the changes in soil properties for sustainable crop production and improving soil health. Asian Australas. J. Biosci.

Major physico-chemical properties of mango orchard soils (Mangifera indica L.) in different sites of three hill districts, Rangamati, Khagrachari and Bandarban were evaluated. Soils were sandy loam in texture at all the sites except foot hill soil of Shapchari. Soil pH, organic matter, total N and available P varied from 4.76 to 5.58, 1.43 to 2.49 %, 0.10 to 0.16 %, 0.86 mg kg-1 to 2.69 mg kg-1 soil, respectively in surface soil of different sites of mango orchard. 1N NH4OAc extractable K+, Ca2+ and Mg2+ ranged from 0.35 to 0.82, 2.50 to 3.66 and 0.60 to 1.57 cmol kg-1 of soils. Soil pH, organic matter, total N and available P varied significantly among the slope positions within the sites. Similar results were found in case of 1N NH4OAc extractable K+, Ca2+ and Mg2+. The soils are generally poor in organic matter and nutrients. DOI: http://dx.doi.org/10.3329/cujbs.v6i1-2.17244 The Chittagong Univ. J. B. Sci.,Vol. 6(1&2):187-197, 2011

The objective of this study was to evaluate the impact of different land use systems on soil erosion rates, surface evolution processes and physico-chemical properties on a moraine hilly topography in Lithuania. The soil of the experimental site is Bathihypogleyi – Eutric Albeluvisols (abe–gld–w) whose texture is a sandy loam. After a 27-year use of different land conservation systems, three critical slope segments (slightly eroded, active erosion and accumulation) were formed. Soil physical properties of the soil texture and particle sizes distribution were examined. Chemical properties analysed for were soil ph, available phosphorus (P) and potassium (K), soil organic carbon (SOC) and total nitrogen (N). We estimated the variation in thickness of the soil Ap horizon and soil physico-chemical properties prone to a sustained erosion process. During the study period (2010–2012) water erosion occurred under the grain– grass and grass–grain crop rotations, at rates of 1.38 and 0.11 m3 ha–1 yr–1, respectively. Soil exhumed due to erosion from elevated positions accumulated in the slope bottom. As a result, topographic transfiguration of hills and changes in soil properties occurred. However, the accumulation segments of slopes had significantly higher silt/clay ratios and SOC content. In the active erosion segments a lighter soil texture and lower soil ph were recorded. Only long-term grassland completely stopped soil erosion effects; therefore geomorphologic change and degradation of hills was estimated there as minimal.

The assessment of abattoir effluent on the physicochemical and microbiological properties of the soil cultivated with flint maize was conducted in the Teaching and Research Farm of Ambrose Alli University, Ekpoma. The experiment was a randomized complete block design (RCBD) with five levels of abattoir effluent (0, 32 x 103, 64 x 10 3, 96 x 103, 128 x 103L/ha) and each was replicated three times. The effluent was collected and analyzed for its chemical properties, the number and types of bacteria and fungi before and at the end of the experiment. Soil samples were collected before planting and at the end of the experiment and analyzed for physicochemical properties as well as the number and types of bacteria and fungi. Maize variety; Samma – 38 was used as a test crop. Results showed that more bacteria and fungi counts were found in the abattoir effluent than in the soil. At 15 weeks after application, the plot treated with 64 x 103 L/ha of abattoir effluent had more bacteria isolated and the least bacteria count. The plot that received the 32 x 103L/ha had the least fungi count. The soil was slightly acidic except for the strongly acidic control. The soil after the applications of abattoir effluent was high in organic matter. Abattoir effluent increased the total N, K, Mg, and Ca with the highest recorded at the applications of 96 x 103L/ha and 128 x 103L/ha. Organisms such as Penicillium and Aspergillus spp were isolated, and these enhanced nitrogen and phosphorous fixation, thereby increasing soil fertility for suitable crop production.

Benke, M. B., Goh, T. B., Karamanos, R., Lupwayi, N. Z. and Hao, X. 2012. Retention and nitrification of injected anhydrous NH3as affected by soil pH. Can. J. Soil Sci. 92: 589–598. Anhydrous ammonia is an economical and extensively used fertilizer, yet loss after injection can reduce its agronomic efficiency. A laboratory experiment was conducted to examine how soil properties affect ammonia retention and nitrification following anhydrous NH3injection using 10 different Canadian prairie soils. Soils were also injected with atmospheric air for comparison. Following injection, soils were incubated for up to 216 h at field capacity. Among the soil properties studied [pH (1:2 water), clay, total N, and organic C contents], only pH was negatively related (R2=0.55, n=10, 24 h incubation) to percentage injected N retained by soil. The amount of N retained by soil 24 h following injection was 92±2% (mean±SEM) when pH <6, compared with 64±2% when pH>7.5. Rate of nitrification increased (P<0.001) about 48–96 h following injection and was greater in pH>7.5 than pH<6 soils. There was no difference (P>0.05) in bacterial diversity between ammonia- and air-injected soils. The slower nitrification rates suggest that potential leaching and denitrification losses in acid soils could be smaller than in alkaline soils.

The objective of the current study was to evaluate effect of terracing on soil chemical and biological properties in the Rwanda highlands. The study was done in March 2017. Composite soil samples were collected from the top, middle and bottom slopes of four-year-terraced and non-terraced lands, in three profile depths, in medium and high altitudes. Results showed that, levels of organic carbon (1.3, 1.04%) were significantly (p less than 0.05) higher in non-terraced than terraced land, and populations of bacteria (3.59, 2.61 CFU*106g-1) and fungi (2.51, 1.57 CFU*104g-1) were significantly higher in terraced than non-terraced land, in the medium altitude, with no significant differences observed in the high altitude. Soil pH, total N, available P, CEC, exchangeable K+, Mg2+ and Ca2+ levels in terraced and non-terraced lands were not significantly different in both altitudes. Thus, soil characteristics and fertility of the study areas showed slight changes after four years of terracing.

The sustainable soil management necessary to maintain soil quality depends on the understanding of how the soil responds to agricultural practices over time. This paper reports the changes in physicochemical properties that resulted from different cropping systems on a soil in Ado Ekiti, Nigeria. Soil samples were collected from sole maize plot (1.0 ha), sole cowpea plot (1.0ha) and cassava/maize intercrop plot (0.6ha) on a land that was previously under fallow. The sand, silt and clay contents of the soil and some selected chemical parameters varied considerably within the study area (different cropping zones). The soil was generally sandy loam and was found to vary from slightly acidic to slightly alkaline and generally low in Soil Organic Matter (SOM) and Available P (Av. P) with no salinity problem. High magnitude of variability was observed for Electrical Conductivity (EC), Av. P and SOM while pH had the least magnitude. A geostatistical evaluation of the soil chemical properties showed moderate to strong spatial dependence. The geospatial maps clearly revealed the heterogeneity of the soil chemical properties across the field. Both classical statistics and geo-statistical analyses of the soil of the area provided a better understanding of the spatial variability of soil chemical properties and the influence that such could have on crop performance. The results indicated that the soil pH is slightly acidic and contained low amounts of both SOM and Av. P. It is suggested that planting of cover crops, minimum tillage and controlled application of phosphate fertilizer should be done so as to increase the SOM, improve Av. P and maintain the soil pH. Further studies should be conducted to include other soil chemical properties such that robust site specific management programme could be effected.

The aim of this study was to examine the effects of seasonal flooding on the properties of floodplain soils of Wukari Area of Taraba state. The treatments consisted of five different locations of Gidan-Idi, Gindin-Dorowa, Tsokundi, Rafin-Kada and Nwuko and three different soil sample depths of 0-20 cm, 20-40 cm, and 40-60 cm laid out in a completely randomized design (CRD) and replicated three times. Soil samples were collected from each plot in 2016 and 2017. All soil samples were analyzed for physical and chemical properties. The results obtained were subjected to analysis of variance and means separated using F-LSD test at p≤.05. The results of the soil properties analysis showed that some of the determined parameters were significantly different at the different sample locations at p≤.05. The soils of Wukari Floodplains are mostly clay loam in texture having very slightly acid to neutral soil reaction, moderate organic matter, low total N, moderate available P, low exchangeable bases and CEC. The flood plain soils were moderate in soil fertility, a confirmation of the general characteristic of Savanna soils. The soils were not deficient in micronutrients. Seasonal flooding had significant (positive) influence on some physical and chemical properties of the flood plains most particularly at Rafin-Kada.

The soil physico-chemical properties have been disturbed due to long continued intensive agricultural practices. Under this situation we are approaching rapidly to a very strong future challenge in sustaining the quality of our soil. This study was conducted to evaluate the physico-chemical properties of the selected soil series. The area covered Mymensingh and Jamalpur districts of Bangladesh. Soil samples were collected randomly from different profiles of Lokdeo, Tarakanda, Silmondi and Melandah soil series during March-May, 2014 and analysed. All soils were acidic and textural classes were sandy loam, silt loam, loam, and clay loam. Organic matter and total N contents low to very low. Available S content in the upper layers of most soils were medium to optimum and in the deeper layer low to medium. The exchangeable K, Ca and Na contents were also low. The upper layers of all the locations contained higher amounts of available Zn. The available Cu and Fe contents of most soils were very high. The soils of all locations contained very high amount of available Mn except the deeper layers (45-75 cm) of Melandah which contained optimum amount of available Mn. Soil pH showed negative correlation with total N and available S. Total N showed positive correlation with soil OM, available Cu and available S. There was positive correlation between available S and available Mn.J. Bangladesh Agril. Univ. 13(2): 197-206, December 2015
