The study of soil physico-chemical properties were made on the soils of BuleHoraWoreda, WestGuji zone. The objective of the study was to characterize soil physical and chemical properties to assess the fertility status of the soils in the study areas. Soil profile pits at representative sites were described and soil samples were collected from each depth of 0-15 cm, 15 – 30 cm, and 30–60 cm depending on the root depth of the crop. Soil samples were collected from two different study areas for the determination of soil texture, bulk density, porosity, soil pH and electrical conductivity. The top layer (0-15 cm) has an average bulk density of 1.10 g/cm3, whereas the subsurface layer (15-30 and the bottom layer (30-60 cm) has an average bulk density of 1.16 g/cm3 and 1.26 g/cm3, respectively at the GuyyeKebele. The average value of bulk density 1.18 g/cm3, 1.29 g/cm3 and 1.39g/cm3 was recorded on the surface horizon (0-15 cm), subsurface horizon (15-30 cm) and the bottom horizon (30 - 60 cm) depth, respectively at BuleHora Farm. Accordingly, the highest (1.39 g/cm3) and the lowest (1.10 g/cm3) average bulk density values were recorded for BuleHoraand GuyyeKebele study Farm, respectively. The average highest porosity (58.48%) value was observed in the surface horizon (0 -15 cm) soil depth and the average lowest porosity value (52.11%) was observed in the bottom horizon (30 – 60 cm) depth at GuyyeKebele study Farm. The average porosity value of the soils in BuleHora study Farm were recorded 55.27%, 52.39% and 47.63% for the surface horizon (0 -15 cm), sub surface horizon ( 15 –30 cm) and bottom horizon (30 – 60 cm) depth , respectively. The soil textural class was changed with depth from sandy clay in surface horizon (0-15 cm) to clay in both sub surface horizon (15- 30 cm) and bottom horizon (30-60 cm) at GuyyeKebele. The pH value was observed on the soils of the GuyyeKebele study area increased from 6.08 at surface horizon (0 – 15 cm) to 6.27 at the sub surface horizon (15- 30 cm) and then slightly decreased to 6.21 at the bottom horizon (30-60 cm) of the soil depth. Lowest soil pH value (5.44) was measured in the surface horizon (0 –15 cm) and the highest pH value (6.09) was observed in bottom horizon (30-60 cm) soil depth at BuleHora farm. The electrical conductivity of the saturated soil paste extracts of the study area was low (ranging from 0.0387 to 0.1587 dS m-1) throughout the profile showing no significant accumulation of soluble salts to convert the soil to saline soil.Int.

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.

The spatial variability of salt accumulation through the soil profile was studied at Latachapali union of Kalapara upazila, Patuakhali district, Bangladesh. The soil samples were collected from 30 locations covering six villages of the union: Kuakata, Malapara, Fashipara, Khajura, Mothaopara and Tajepara. Five locations were randomly selected from each village. From each location soil samples were collected from three soil depths at 0-2 cm, 2.1-4 cm and 4.1-6 cm. Electrical conductivity of top 0-2 cm soil depth was 20.49 dS/m, in 2.1-4 cm soil depth was 7.14 dS/m and in 4.1-6 cm soil depth 4.15 dS/m. The study soils were strongly acidic having pH value 4.73, 4.99 and 5.20 in 0-2, 2.1-4 and 4.1-6 cm soil depth, respectively. The highest of 8.8 Na:K ratio was found in 0-2 cm soil depth. The Na:K ratio gradually decreased with the increase of soil depth, having 6.59 in 2.1-4 cm and 5.42. in 4.1-6 cm soil depth. The results clearly reveal that the top soil is very much sensitive to salt stress. Based on the electrical conductivity and Na:K ratio the Fashipara, Kuakata and Tajepara village were found seriously affected by salinity.Journal of Bangladesh Academy of Sciences, Vol. 42, No. 1, 11-23, 2018

Soil depth can significantly influence the availability of nutrients in soil. An experiment was conducted with seven soil samples from seven land use types to observe the effect of soil depth on soil properties under various land use systems. Soil pH, electrical conductivity (EC), organic matter, available phosphorus (P), available sulphur (S) and different forms of potassium (K) such as water soluble, exchangeable and non-exchangeable were determined from the soil samples collected from four soil depths (viz. 0-10, 10-20, 20-30 and 30-40 cm). Soil pH varied from 6.30-7.39 irrespective of depths and land uses and it increased with increasing soil depth. Electrical conductivity of the soils ranged from 42-310 µS cm-1 and organic matter status of most of the soils was very low to medium in level. Both EC and organic matter content decreased with the increase of soil depth. Available P concentration showed no specific changing trend with soil depth whereas available S concentration under different land use systems decreased with increasing soil depth. The concentrations of water soluble, exchangeable and non-exchangeable K in soils varied from 12.30-39.60, 20.90-53.16 and 163.30-684.30 mg kg-1, respectively and showed no specific changing pattern with soil depth. Water soluble K content was higher in rice growing fertilizer and manure-treated soil but higher exchangeable and non-exchangeable K contents were observed in banana growing soil. In rice growing soils, nutrient concentration is mostly higher in nitrogen (N), P and K + farm yard manure (FYM) - treated plots compared to rice growing control plots.

Application of animal manures for soil amendment plays a major role in the improvement of soil properties and enzymatic activities of a degraded Ultisol. This study assessed the effects of poultry manure (PM) and swine manure (SM) on the activities of catalase and urease enzymes and some soil properties. The PM and SM were applied at the rate of 30 t ha–1 each on experimental plots arranged in a randomized complete block design with three replicates. Soil samples were collected at day 0, 14, 28, 42, 56, 70 and 84 from 0-15 and 15-30 cm depths and analyzed for catalase and urease enzymes and some soil properties using standard procedures. The results showed increase in soil pH (in H2O) from 4.0 to 5.4 following manure application. At 0-15 cm soil depth, PM and SM recorded 28.1 and 28.8% increases in soil pH (in H2O), respectively. Soil organic carbon was highest (2.6 g kg–1) at 0-15 cm depth for soil amended with SM while the lowest value of 1.1 g kg–1was obtained at 15-30 cm depth for soil unamended with SM. In PM-amended soil, catalase activities ranged from 1.32 to 6.77 mg g–1 while its activities in SM-treated soil significantly (p < 0.05) varied between 1.55 and 8.11 mg g–1. Urease showed ranges of 0.72-3.90 mg g–1 and 0.96-4.71 mg g–1 in PM-amended and SM-treated soils, respectively. The results uphold that animal manures improve soil properties and are enzymatically controlled.

The present investigation was carried out to characterize and classify some typical healthy and declined Nagpur mandarin gardens in Warud and Morshi Tahsil’s of Amravati District (M.S.). Total forty two representative surface and depth soil samples from healthy and declined Nagpur mandarin gardens were collected and analyzed for various physico-chemical properties. The findings revealed that the texture of soil is clayey (40 - 59 % clay in healthy gardens and 47.4 - 61.4 % clay in declined gardens). The bulk density and porosity in healthy gardens ranged 1.51 - 1.67 mg.m-3, 35.85 - 43.02 % in declined gardens; it varied from 1.51 to 1.66 mg.m-3 and 25.85 to 43.02 % respectively. The pH, organic carbon and CaCO3 content in healthy gardens soils varies 7.5 - 8.0, 4.8 - 9.0 g kg-1, 5.35 - 8.31 % and in declined gardens it’s 7.7 - 8.2, 1.95 - 3.75 gm kg-1, 6.71 - 10.53 % respectively. The electrical conductivity and cation exchange capacity of healthy gardens soil was noticed 0.21 - 0.28 d.Sm-1, 45.92 - 55.53 c.mol (p+) kg ha-1 and in declined gardens it varied 0.22 - 0.32 d.Sm-1, 46.20 - 51.92 c.mol (p+) kg ha-1 respectively. Further, no significant difference was found in clay, bulk density, porosity, electrical conductivity and cation exchange capacity in healthy and declined gardens; however soil reaction was found high in declined gardens than healthy gardens. Organic carbon content was high and free lime content was reported lower in healthy gardens than declined gardens. Study on depth wise distribution showed that bulk density, pH and electrical conductivity increase with soil depth. Organic carbon and cation exchange capacity decreases with soil depth. The available nitrogen, phosphorus and potassium content of healthy gardens surface soils are ranged 206.0 - 273.7 kg ha-1, 25.0 - 38.3 kg ha-1, 324 - 672 kg ha-1 and in declined gardens it’s varied as 135.4 - 206.8 kg ha-1, 19.8 - 23.3 kg ha-1, 364 - 750.4 kg ha-1 respectively. Available nitrogen and phosphorus content in healthy gardens found more supporting than declined ones. Depth wise distribution showed that available nitrogen and phosphorus showed decreasing trend with the soil depth.

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.

Abstract Background: Understanding the soil reaction (pH) is relevant for improving crop productivity. Soil acidity is one of the restraining factors to crop production in the highlands of Ethiopia. This study was carried out on the nitisols of Burie District to examine the effect of integrated use of Calcite and Nitrogen fertilizer on soil physico-chemical properties. Treatments were two levels of lime (0 and 0. 50 t ha-1) and five-level of nitrogen (0,100, 200, 300, and 400 kg ha-1). The experiment was laid out in randomized complete block design (RCBD) with ten treatments replicated three times. Before and after harvest, both disturbed and undisturbed soil samples were collected. Analysis of variance (ANOVA) and bivariate correlations was employed using SAS statistical package program version 9.0. After harvesting thirty soil samples were collected from each treatment and then ten composite soil samples within a block were arranged for laboratory analysis. Result: The result indicated that among the soil properties before planting the crop soil bulk density (BD), pH, organic carbon (OC), total nitrogen (TN), available P and CEC were 1.43g cm-3, 5.2 (strongly acidic), 1.32% (very low), 0.12% (low), 8.86 mg kg-1 (very low), and 19.57 cmolc kg-1 (medium), respectively. After harvesting, most of the surface physico-chemical properties except bulk density increased. The lowest soil BD was 1.21 g m-3 from plots treated with 0.5 t ha-1 lime and 400 kg ha-1 urea. The maximum soil pH (6.85) was obtained from plots treated with 400 kg ha-1 N and 0.5 t ha-1 lime. The maximum soil CEC (35.38 (cmolc kg-1) was obtained from plots treated with 400 kg ha-1 N and 0.5 t ha-1 lime. Level of lime, nitrogen fertilizer and interaction effects of lime and nitrogen fertilizer (L*N) significantly affected maize yield (p<0.001). Yield of maize have positive correlations with most soil physico-chemical properties but negative with BD (r=-0.543).The adjusted yield and net benefit was 6,410.20 kg ha-1 and 58,891.47 Ethiopian Birr (ETB), respectively.Conclusion: Inherent physicochemical properties of the soil is changed either by sole or combined use of lime and N fertilizer. Soils tilled with 0.5 t ha-1 lime and 138 kg ha-1 nitrogen was found in maximum net benefit. Residual long-term effects should be researched. Thus, liming should be given emphasis in acidic soil amelioration. Moreover, the government may facilitate the supply of calcite (CaCO3) and urea fertilizer to the farmers.

The Impact

The present study has been done to evaluate the impact of pure ash stand and mixed stand with beech on the herb layer biodiversity and soil properties in the forests of Noor city. There is a unique stand of ash in the forests of Noor city and at 1,900–2,100 m a.s.l., which is rarely seen like that in the northern forests of Iran. Shannon-Wiener diversity indices (H’), Simpson index of dominance (D), Margalef richness (R<sub>1</sub>) and Pielou’s evenness were used to analyse biodiversity. Sampling was also conducted to investigate physical and chemical properties of soil (bulk density, acidity, electrical conductivity, soil moisture, soil lime, nitrogen and organic carbon) in each sample plot and at two depths (10 and 20 cm). The total number of 26 soil samples (13 soil samples at either depth) in pure ash stand and 24 soil samples (12 soil samples at either depth) from this type of stand mixed with beech were taken. The results of plant species biodiversity showed that between the pure ash stand and the stand mixed with beech there is a significant difference at the 99% probability level in Shannon-Wiener diversity, Margalef richness, and Simpson dominance. There is also a significant difference at the 95% probability level between the two stands under study in Pielou’s evenness index. The results of soil factors also showed that at the depth of 10–20 cm acidity factor showed a significant difference from its adjacent stand at the 99% probability level. There is also a significant difference at the 99% probability level in acidity (0–10 cm) and soil moisture at the depth of 10–20 cm between the two areas, but there is not any significant difference between the areas under study in electrical conductivity and lime factors at the two depths and also in moisture content at the depth of 0–10 cm. It should be noted that between the stand and soil nitrogen, organic carbon and bulk density parameters at both depths (0–10 and 10–20 cm) a significant difference at the 95% confidence level is shown.

This article provides information on selected physico-chemical properties, including soil colour, texture, electrical conductivity, pH<sub>H</sub>2O, pH<sub>CaCl</sub>2, content of total carbon and Q<sub>4/6</sub> quotient, of the topsoil and subsoil of former flood sediments at three diverse vegetation plots in a floodplain and in two reference plots unaffected by floods, and changes of some soil properties caused by a new subsequent flood. Aggradation of flood sediments in the area was controlled both by local terrain morphology and vegetation type cover. Differences in the properties of sediments in the individual plot types were caused by the different production of litter, root biomass and carbon cycling before the new flood. Vertical distributions and inventories of <sup>137</sup>Cs in soils revealed the position and proportion of modern sediments in soil profiles, man-made filling of former erosion grooves and ploughing depths. The new flood of a lower hydrological power aggraded a thin layer of organo-clay sediment on the soil surface but showed minor effects on the investigated soil properties. The lowest dry bulk density and highest total porosity values were found in the topsoil of woody and grassy plots after the flood implying no substantial break down of soil aggregates by the flood. The highest dry bulk density values in the subsoil of fields indicated soil compaction from agricultural machinery. No increased soil salinity was found after the flood. The flood did not significantly affect the pH<sub>H</sub>2O of the topsoil and subsoil; however, a significant increase in pH<sub>CaCl</sub>2 was found for the topsoil of grassy plots and for all topsoil samples from the park. No significant increases in total carbon (C<sub>tot</sub>) contents were found in topsoils of any plot types after the flood in spite of an accumulation of thin organo-clay material on the soil surface after the flood. However, significant increases in C<sub>tot</sub> in subsoils of all plot types indicate the vertical migration of colloidal and dissolved organic carbon in soils during the flood. C<sub>tot</sub> contents positively correlated with electrical conductivity values and negative correlated with pH values. The relatively minor changes in soil physico-chemical properties found after the flood can be explained by the short duration and small dynamic power of the flood, and the timing of sampling when the flood had receded and soil aeration was already being restored.
