Properties Of Soil

An experiment was conducted to examine the physicochemical properties of soil at Habla union under Basail upazila in Tangail based on the BINA (Bangladesh Institute of Nuclear Agriculture) laboratory analysis of physical and chemical parameters during January to March, 2014. Total 30 soil samples from 10 points of Habla union were collected from 0-15 cm, 15-30 cm, and 30-40 cm depth of the soil respectively. To determine the soil texture the results were compared with the standard value of SRDI and BARC. Among the 30 soil samples, 25 soils texture classes were found sandy clay loam, 4 were sandy clay and rest one was clay loam. The comparative analysis showed that the average texture class is sandy clay loam. The bulk density ranged from1.23 to 1.91 g/cm3 for the total samples which leads to decide that bulk density is gradually increasing with soil depth. The moisture percentage at different depth of soil were 39.23 to 57.23 % (for 0-15 cm), 43.02 to 58.35 % (for 15-30 cm) and 42.08 to 58.24% (for 30-45 cm).The pH obtained from soil samples of the study area were 4.66 to 5.55 (for 0-15cm), 5.37 to 6.18(for 15-30cm), 6.33to 6.60 (for 30-45 cm). The percentage of organic matter of the soil samples were 0.55 to 3.97 % (for 0-15cm), 0.55 to 3.24 % (for 15-30cm), 0.69 to 2.28 % (for 30-45cm).The organic matter content in the surface soil is relatively low compared to standard level that decreases steadily with depth. The percentage of nitrogen (N %) was observed in different depth of the soil were 0.078 to 0.126 % (for 0-15 cm), 0.049 to 0.126 % (for 15-30 cm), to 0.074 % (for 30-45 cm) which revealed that the percentages of total nitrogen were fall with the depth compared to standard level. In different depth of soil, it was observed that the level of phosphorus (P) was very low compared to standard level where the phosphorus (P) concentration of the soil samples were 1.18 to 2.90 mg/kg (for 0-15 cm), 1.30 to 9.95 mg/kg (for 15-30 cm), 1.58 to 10.92 mg/kg (for 30-45 cm). On the other hand, it was observed that the sulfur (S) concentration was increased with the depth of soil compared to standard level. The sulfur (S) concentration of the soil samples were 5.21 to 11.98 mg/kg (for 0-15 cm), 5.37 to 14.16 mg/kg (15-30 cm), 9.03 to 15.09 mg/kg (30-45 cm). The potassium (K) concentration of the soil samples were 0.038 to 0.102 mg/kg (for 0-15 cm), 0.031 to 0.90 mg/kg (for 15-30 cm) 0.055 to 0.171 mg/kg (for 30-45 cm), which indicated that the low K content compared to the standard level. The overall physicochemical parameter of soil samples were not optimum for good agricultural production. As we know all the parameters either directly or indirectly influence the soil fertility and productivity. This was probably the reason for low productivity of soil in the study area.Asian J. Med.

Since contamination of soil with cobalt disturbs the soil’s biological balance, various types of compounds are being sought that could be used to restore the homeostasis of contaminated soil. The aim of the study was to determine the use of a Bio.Zeo.S.01 zeolite and molecular sieve in restoring the microbiological and biochemical balance of soil contaminated with cobalt. Soil samples were contaminated with cobalt (CoCl2·6H2O) at 0, 20, 80 mg·kg−1, and a Bio.Zeo.S.01 zeolite and molecular sieve were introduced at 0 and 15 g·kg−1. The soils on which the experiment was conducted were loamy sand and sandy clay loam. The experiment was carried out in two series on soil with and without a crop sown in it. The multiplication of microorganisms and the soil enzymes’ activity were determined on days 25 and 50 (harvest) of the experiment, and the yield of the underground and above-ground parts of maize and chemical and physical properties of soil were determined on the day of harvest. It was found that the microorganisms’ multiplication, enzyme activity, and maize yield were significantly disturbed by the excess of cobalt in the soil regardless of the soil type. The zeolite Bio.Zeo.S.01 used in the study had a smaller impact on microorganisms and soil enzyme activity than the molecular sieve. Cobalt accumulated more in the roots than in the above-ground parts of maize. An addition of sorbents decreased the accumulation of cobalt in maize grown only on sandy clay loam.

This paper discusses the distribution of selected heavy metals namely chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn) in soil from Kimanis, Papar, Sabah. Fourteen soil samples were collected from soil originated from sedimentary rock of Crocker Formation and Quaternary deposit. The Crocker Formation consists of thick sandstone unit and inter-bedded sandstone and shale unit with the age of Late Eocene to Early Miocene. The physico-chemical analysis of soil include the pH value, moisture content, organic content and particle size. Soil of Crocker Formation were classified as sandy loam and sandy clay loam, while Quaternary deposit were classified as sand, sandy loam, sandy clay loam and clay with loam. The result of analysis shows the soils were acidic with pH values range from 3.06-5.65. Organic matter content ranges from 0.98%-7.63% and moisture content were 13.8%-60.51%. All heavy metals were analyzed using ICP-OES. The result of analysis indicated that Zn shows the highest value then followed by Cu, Pb and Cr. Soil sample from Crocker Formation show significantly high Zn and Cu content, where SC6 and SC7 have Zn value of 274.36 μg/g and 127.82 μg/g respectively, whereas 127.98 μg/g of Cu. The distribution of heavy metals in soil samples are controlled by the mobility and leaching process during chemical weathering and also adsorption by clay particles and organic matter as well as the human activities within the area.

Use of imbalanced chemical fertilizer and changing crop and cropping pattern are becoming a serious threat for the sound environment of the soil. The study provided an assessment of the present status of soil quality of Tangail Sadar based on the laboratory analysis of physical parameters such as bulk density, water holding capacity, sand, silt and clay percentage from July, 2010 to December, 2010. 40 soil samples from 20 different places were collected from 0-15 cm and 15-30 cm depth of the soil from 5 locations mentioned as Porabari, Santosh, Gharinda, By-pass and Ashekpur. The study conducted revealed that among the 40 soil samples, 30 soil's textural classes are sandy clay loam, 7 are sandy clay and rests 3 are clay loam and the pH value ranges from 5.3 to 6.4. The comparative analysis shows that the average texture class is sandy clay loam, which is not relevant to the standard level because the standard texture class is loamy. The average moisture percentage, bulk density and water holding capacity are found 2.865 %, 0.0926 gm/cm3 and 9.44% respectively which are almost similar to standard values and almost soil are suitable for plant growth.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10160  J.

Aims: The detailed survey of the microwatershed was carried out by using digitized cadastral map as a base. The objective of the investigation was undertaken to characterize and classify the soils of Harve-1 microwatershed of Chamarajanagar district, Karnataka. Place and Duration of Study: soil survey was done and soil samples were collected from Harve-1 microwatershed of Chamarajanagar district in the year 2016. The laboratory characterization and soil classification work was done at National Bureau of soil survey and land use planning, Regional centre Hebbal, Bangalore, Karnataka. Methodology: Using Cartosat-1 and LISS-IV merged satellite data at the scale of 1:7920 were used in conjunction with the cadastral map as a base. Soil profiles were exposed and location of soil profiles was recorded using GPS and studied from each landform for describing morphological characteristic as per the guidelines given in USDA soil survey manual (Soil Survey Staff 2014). Based on the soil-site characteristics, ten soil series were identified using the method employed by Reddy (2006). Horizon wise soil samples were collected, processed and analysed for various properties by adopting standard procedure. Results: The study showed that, the soils were moderately shallow to moderately deep in depth. The colour of the soils varied from dark red to dark reddish brown. Texture of the soil varied from sandy loam to sandy clay loam in surface and sandy clay loam to sandy clay in subsurface. The structure was weak medium sub-angular blocky to moderate medium sub-angular blocky throughout the profile in all series. The consistency of majority of the soils were friable, slightly sticky and slightly plastic in surface and friable, moderately sticky and moderately plastic in subsurface. Soil reaction varied from slightly acidic to alkaline (5.70 to 8.18) in nature. Organic carbon content of the soils was low to high (0.20 to 1.24 per cent). Calcium and magnesium are dominant exchangeable cations followed by sodium and potassium. The CEC of the soils ranged from 3.17 to 25.76 cmol (p+) kg-1. Major proportion of soil series in the microwatershed belonged to the order of Alfisols (Paralitic Rhodustalfs, Typic Rhodustalfs, Typic Haplustalfs and Rhodic Paleustalfs) except Honnenahalli (HNH) series belong to the order of Inceptisols (Typic Haplustepts). Conclusion: The soils of the microwatershed were comes under the order of alfisols and inceptisols. This generated information can help the researchers, farmers and planners to manage the natural resources for future planning and also to achieve sustainable productivity.

Limiting Values

ABSTRACT This study tested the hypothesis that the limiting values of S-index, proposed in the literature can not be used to determine the degradation condition of soils under soybean cultivation in the state of Pará, Brazil. The objective was to determine limiting values of S-index using soil physical attributes and validate it with soybean root growth, in soils with different textural classes. For the experimental design, the following treatments were established: five compaction levels for sandy loam and sandy clay loam soils and three levels for clayey and very clayey soils. The following physical parameters were analysed: particle-size distribution, soil bulk density, critical soil bulk density, degree of compaction, soil-water retention curve, S-index and relative root length of soybean. The limiting values of S-index varied according to soil textural class and were equal to 0.037, 0.020 and 0.056 for sandy loam, sandy clay loam and clay, respectively. The S-index does not apply to soils with clay content > 71%, because it does not vary with the degree of compaction of the soil or the root growth of the evaluated crop.

Flurtamone and atrazine adsorption to soil was examined using a batch equilibrium method. Flurtamone mobility in packed soil columns under saturated flow conditions was also evaluated. Adsorption was greater for flurtamone than atrazine in the three soils, and the order of adsorption to soil for both herbicides was Greenville sandy clay loam > Cecil loam > Dothan loamy sand. Greater adsorption of each herbicide corresponded to soils with greater organic matter and clay content. The14C–flurtamone movement under saturated flow conditions in 28–cm soil–packed columns was limited to 16 cm, with no flurtamone leaching from any soil column after the addition of two pore volumes of water. Seventy–five percent of the applied14C–flurtamone remained in the 0– to 4–cm soil depth in the Greenville sandy clay loam, with less than 5 percent moving to a depth > 4 cm. Flurtamone movement was greater in the Cecil loam and the Dothan loamy sand, with movement in each soil to a depth of 16 and 12 cm, respectively.

Soil bulk density was related to loblolly pine (Pinustaeda L.) seedling establishment and growth during the first 28 weeks after sowing. Seedling heights were lower when bulk densities exceeded 1.3 Mg m−3 on a sandy clay loam and 1.4 Mg m−3 on a loamy sand. Heights were also lower for bulk densities below 1.2 Mg m−3 on the sandy clay loam soil. Seedling depth of rooting, root weight, and shoot weight were reduced at high bulk densities on both a sandy clay loam and a loamy sand. However, root and shoot weights were also reduced when bulk density fell below 1.3 Mg m−3 on the sandy clay loam. Bulk densities for best seedling growth were 1.3 Mg m−3 for the sandy clay loam and 1.4 Mg m−3 for the loamy sand.

Nickel Adsorption

There is little information on nickel adsorption by Brazilian soils. The objective of this experiment was to determine the effect of pH, organic matter, and iron oxides on nickel adsorption by three soils: a clayey Anionic "Rhodic" Acrudox, a sandy clay loam Anionic "Xanthic" Acrudox, and a clayey Rhodic Hapludalf. Soil samples were collected from the 0-0.2 m layer and treated to eliminate organic matter and iron oxides. The nickel adsorption was evaluated in the original samples and in those treated to remove organic matter and to remove both, organic matter and iron oxides, using 2 g soil + 20 mL of 0.01 mol L-1 CaCl2 solution containing 5 mg L-1 Ni, pH varying from 3.5 to 7.5. The nickel adsorption decreased with the elimination of organic matter. For the samples without organic matter and iron oxides, adsorption decreased only in the Anionic "Rhodic" Acrudox. The pH was the main factor involved in nickel adsorption variation, and for soil samples without organic matter and iron oxides, the maximum adsorption occurred at higher pH values.
