Background: The soil fertility assessment is crucial for sustainable agriculture and plant yields. knowledge of the trophic level agricultural mandatory in order to define development food crops due lack this region decrease crop Methods: In context, an investigation was carried out study status Mansala-Kayikoro soils some essential properties, such as pH, CEC, OM, EC etc. Ten samples were coll...

To provide enough space to carry all surface charges responsible for high cation exchange capacity of plant roots, large area of the root specific surface is necessary, however all experimental methods used up to date give too small surface area values. In this paper, we propose to measure the plant roots surface area using water vapor adsorption isotherm. This method gives roots specific surfa...

Combined ion-exclusion and cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin in the H-form (TSKgel Super IC-A/C) has been used as an advanced method for evaluation of the photooxidation of ionic nitrogen compounds, for example triethanolamine, trimethylamine, and urea, on a TiO2 photocatalyst. Formation of NH4 and NO3 from each nitrogen compound by photooxidation...

Natural montmorillonite was modified with a quaternary ammonium compound, hexadecyltrimethylammonium (HDTMA). The sedimentation capabilities of unmodified and modified montmorillonites were then investigated. The sedimentation velocity of modified montmorillonites increased if the amounts of adsorbed HDTMA were from 0.3 to 1.0 times the cation exchange capacitity (CEC). It also emerged that the...

The binding of alkalis and calcium to silicate hydrate (C-S-H) can be measured by cation exchange using cobalt hexamine solution with adapted pH. effective capacity (CEC) decreased at higher Ca/Si in C-S-H. A maximum chargeexch/Si 0.08–0.10 was = 0.8 decreasing 0.01–0.02 1.6. At high Ca/Si, only a minor fraction Ca present exchangeable sites, while most the Ca2+ interlayer or surface specifical...

Soil cation exchange capacity (CEC) measures the capability of soils to hold and release nutrients. It is an important measure for classifying planning nutrient additions, but it not included in routine soil tests offered farmers. In this study, we compared CEC measured with standard laboratory practices (neutral ammonium acetate [AAc]) estimated from agronomic test data (Mehlich-3 AAc). We app...

This present communication delt, Inputs variability of major input parameters with temperature may possible given example lower stretches river Ganges fisheries and other biological importances. Earlier we found that soil cation exchange capacity CEC has a significant impacts on biology. Any tallness lead to dwarfness higher applicable for both plants animals. Both growth reproduction negetivel...

We evaluated the use of ion-exclusion chromatographic systems for analyzing the behavior of inorganic ions (e.g., bicarbonate, sulfate, chloride, nitrate, phosphate, dissolved silicate, sodium, ammonium, potassium, magnesium, and calcium ions) in a suburban river located in Jakarta, Indonesia. Carbonate, phosphate, and silicate ion concentrations were determined using ion-exclusion chromatograp...

In this study, we investigated the predictive indices for hypoglycemic effect of physically modified fibers. Micronization, ultrasonic, microwave and extrusion cooking treatments were applied to defatted rice bran dietary fibers to get modified defatted rice bran dietary fiber. The effects of physical treatments, pH and time of digestion, on the water binding Capacity (WBC), Swelling Capacity (...

In this study, the properties and adsorption behaviors of organoclays synthesized with two structurally different surfactants having same carbon chain length (hexadecyltrimethylammonium bromide (HDTMAB) benzyldimethylhexadecylammonium chloride (BDHAC)) were evaluated. The structural examined using Fourier-transform infrared spectroscopy, zeta potential analysis, X-ray diffraction, N2 adsorption...
