Soil minerals and  chemical properties play an essential role  in agricultural, especially to know  the  availability of soil nutrient reserve. The objective of the study was to investigate soil chemical properties and mineralogical  composition. of sand fraction in original area. The study was conducted in two stages. The  First stage was in the field and the second stage was in the laboratory. The field study was at Original area PT. Khotai Makmur Insan Abadi, Kutai Kartanegara, East Kalimantan. Soils were sampled from each horizon of the profile. The second stage was in the Laboratory. The chemical analysis was conducted    in  the Soil Laboratory,  Agriculture Faculty,  Mulawarman University.  The Mineralogical composition of fine sand fractions was  conducted in Pusat penelitian tanah Bogor, with line counting method using Microscope Polaritation (MP). The results of chemical characteristics indicated that  low to very low content of organic matter, soil reactions are acid throughout the horizon,  very low to moderate  base satration, low to moderate soil cation exchange capacity, high of Al saturation.  Sand fraction composition was dominated by resistant minerals (quartz and opaque). On the other hand the easily weatherable minerals are not detected in the original area. One of the reason soil has low  CEC is, because the composition of sand fraction in the soil dominated by quartz.

1. Previous investigations showed that certain Scottish soils were of glacial drift origin, that they were comparatively rich in unweathered silicates and therefore in reserves of plant-food, that they showed considerable variation in such silicates and were capable of classification accordingly. Some indication was also shown that the glacial drift, and hence the resulting soil, was sometimes of local origin, its character being determined by the underlying rock. In the present investigation a more extensive survey of Scottish soils has been made in order to discover to what extent these preliminary findings might be applicable generally.2. For this purpose soils have been collected from various localities in the north, north-east, west and south of Scotland, and have been analysed mechanically and the “fine sand” fraction examined mineralogically.

Grey Wooded profiles representing five soil series developed on glacial till in Alberta were studied. The clay mineral fraction in these soils was found to contain montmorillonite, illite, kaolinite and quartz. Authigenic chlorite and "mixed layer" structures were present in the soil sola. Examination of the fine sand fraction revealed the presence of quartz, potash-feldspars and soda-calcic feldspars in the light (sp. gr. < 2.70) mineral fraction with biotite, muscovite, chlorite and highly weathered amphiboles and pyroxenes comprising the intermediate (sp. gr. 2.70–2.96) mineral fraction. The heavy (sp. gr. > 2.96) mineral fraction contained primarily iron oxides, amphiboles, garnets and pyroxenes with a wide variety of other minerals in relatively low quantities.The mineralogical data presented suggest variations in weathering in the sola of the soils studied, despite their similar morphological features. Active and exchange acidity showed little relationship to the degree of mineral weathering. Weathering appeared to be more severe in horizons where acid conditions result from the presence of exchangeable hydrogen rather than where similar acid conditions result from exchangeable aluminium. The mineralogical study was found to be exceedingly valuable in distinguishing between morphologically similar materials of different lithology.

Growth Of Seedlings

Success in the production of eucalyptus seedlings directly affects the development of plants in the field. Several factors influence their initial growth, especially the substrate. This study aimed to evaluate the growth of Eucalyptus globulus seedlings and characteristics of the substrate using silicate agromineral (SA) in different proportions (substrate:SA; v/v): T0 – 100:00%, T1 – 90:10%, T2 – 80:20%, and T3 – 50:50%. The treatments were evaluated using a completely randomized design. Measurements of height (H), stem diameter (SD) and calculation of the H/SD ratio of the plants were performed every 3 weeks, totaling 4 measurements. At the end of the experiment (12 weeks), soil fertility analyses, granulometric analysis (sand, silt and clay) and total chemical analysis were carried out. Due to the chemical and mineralogical composition of SA, its use in substrate in a greater proportion (T3) promoted the increase of exchangeable K, Ca and Si contents, which influenced the increase in the sum of bases and cation exchange capacity. The levels of assimilable P and micronutrients Fe, Cu, Zn and Mn were also higher in this treatment. The increase in  SA proportions in the substrate composition also favored increase in the sand fraction and reduction in the clay fraction. As for the growth of seedlings, the results were not significant for H and SD as a function of SA doses, leading to the conclusion that the solubilization and slow release of nutrients by SA did not influence the growth of the plants

Abstract Background: - Land degradation is one of the major challenges in agricultural production Ethiopia. To combat the problem different Soil and Water Conservation (SWC) measures were introduced. Methods: - This research was conducted in the Masha Deniba micro-watershed, Dawuro Zone, Southern Ethiopia aimed to assess impact of stone bund conservation on soil properties. This study compared the effects of stone bund age along landscape positions. Surface soil sample from 17 farms were collected and analyzed for soil bulk density (BD), organic matter (OM), total nitrogen (TN), pH and cation exchange capacity (CEC) of soil. Result:- Results showed that farms treated with stone bunds showed improvement in soil chemical properties. For most parameters, the peak was obtained from stone bunds having 10 years age. The non- conserved plots had the lowest soil nutrients contents. Lower topographic position had shown higher nutrients contents than farms in upper topographic position. Overall, OC, TN, S and B contents were low in the watershed. Conclusion: - From the finding we can conclude that stone bunds improved soil nutrient when compared to non-treated farm with the respect of age and landscape position. But constructing physical structures alone does not restore the soil fertility to the level that the crop is demanding. Thus, integration of physical conservation with agronomic and biological measures is highly recommended.

Vertisols is black and fertile soils, derived from various parent materials, dominated by smectite clay minerals, and charasterize by crack formation during dry season. Six soil profiles consisted of thirty two soil samples from dIfferent location were analyzed for their chemical and mineralogical composition at the laboratories of Soil Research Center for soil characteristics. Results indicate that the color matrix of Vertisols varies, hue range from 2.5Y to 10YR, color value varies from 2 to 6, and chroma range from 0 to 4. Clay mineral composition of Vertisols is dominated by smectite. Other clay minerals founded in the Vertisols are kaolinite, illite and vermiculite. The mineralogy composition of sand fraction is varies, some of them rich in weatherable minerals like andesine, amfibole, orthoclase, sanidin and the others are dominated by resistant minerals such as quartz and opaque. The mineralogical composition of Vertisols dependent on their parent material. The dominant cations in Vertisols are Ca++ and Mg++. Vertisols from volcanic materials is dominated by Ca++ and followed by Mg++ cations, Vertisols from limestone is dominated by Ca++, while Vertisols from peridotite is dominated by Mg++. All of the Vertisols studied have a high cation exchange capacity with pH’s range from 5.5 to 7.4. In using Vertisols for food plantation, should be consider the high content of Ca++, Mg++ and the water management. The soils should be atleast always in moist condition, otherwise soils become very hard and cracks when dry.

Mineralogical Study

A mineralogical study of the fine sand fraction of unweathered tills and stratified sands chosen to represent the deposits of the major ice lobes of southern Ontario was carried out. In addition, a few analyses were made of the coarse silt and coarser sands.In general there was the same variety of minerals in all samples and they varied only in their proportions. Tills overlying Palaeozoic bedrock contained abundant carbonates and shale fragments constituting up to 70 per cent of some fine sands. In the coarse sands, carbonates and shale increased sharply. In the coarse silt and fine sand, feldspars were more abundant than quartz whereas in the medium and coarse sand the reverse was true. Quartz increased in quantity with increasing grain size and reached a maximum in the medium sand. Heavy minerals usually constituted less than 15 per cent of the fine sand. Some of the minerals present in the coarse silt and fine sand were not found in the coarser sands. Usually the order of abundance of the heavy minerals was: hornblende, garnet, micas, magnetite, pyroxenes and sphene. Epidote, rutile, apatite, tourmaline, staurolite, kyanite and others were also noted. A chart listing the plant nutrient elements found in these minerals was prepared.

The objective of this study is to describe the mineralogical composition and chemical properties of the Oraşu Nou bentonite, from northwestern Romania. For mineralogical determinations, the following were used: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FR-IR), thermogravimetric analysis, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX). The chemical compositions and physical properties of the bentonites and bentonitized rocks were also determined. Calcium type montmorillonite is the predominant mineral in this deposit. Its average mass fraction is between 35% and 75%, reaching up to 95%. A small amount of halloysite and very fine cristobalite were also identified in the fine fraction. Quartz, feldspar, and kaolinite were identified as impurities. The average pH of natural bentonite is 6.2. Its cation exchange capacity (CEC) is in the lower-middle range for smectites at 45.89 cmol/kg, absorption capacity 43.58 mL/g, swelling degree 9.41%. Because of the high amounts and purity of montmorillonite, the valuable component mineral, the way is open to an easy refinement of this important resource. This way very high-quality colloidal suspensions can be obtained which can be used in the most modern applications of micro- and nanostructured materials.
