Element Removal

The accumulation of salts in the soil produces conditions that affect the growth of most crops. Currently, soil amendments have been used to improve the texture and chemical & biological reactions of the soil. The objective of this work was to simulate the transport of sodium, potassium, calcium and magnesium in columns of saline soil through the use of organic and chemical amendments. Saline soil samples of the municipality of Tlahuelilpan, Hidalgo state, Mexico were studied. Compost, vermicompost, phosphogypsum and malting barley husk were used as amendments. The results showed that the highest metal element removal was obtained with the combined treatment of vermicompost at 4 % and phosphogypsum at 2 % (V4FY2) (59 %). Improvements in soil physico-chemical properties were also observed. These findings indicated that the combination of organic and chemical amendments promotes the leaching of metals, (mainly sodium). Therefore, the amendments evaluated in this study can be a good alternative for the remediation and improvement of saline soils.

Pecans are cultivated extensively in the Yaqui Valley, Sonora. These soils often have problems of salinity and high concentrations of exchangeable sodium, which cause a decline in pecan productivity. At the end of the season of irrigation with water from the system of reservoirs on the Yaqui River, groundwater is generally used from May to August. This can result in salt accumulation in the soil when water is of poor quality. Gypsum has been used as an amendment to rehabilitate soil by improving its physical and chemical properties. The main objective of this study was to investigate the effect of gypsum application to a saline soil of a pecan orchard in the Yaqui Valley. Rehabilitation was carried out for two consecutive years. In the first year a dose of 5 and 10 Mg ha‑1 was applied, while in the second year 2 Mg ha‑1 of gypsum was used. Two ridge washings were done after each aplication. The physico-chemical analyses of the soil were conducted following NOM-021-RECNAT-2000 during three years prior to and after the applications of amedment. Once the amendement was applied, the values of electrical conductivity decreased from 12.41 to 6.29 dS m-1, percentage of exchangeable sodium from 12.48 to 5.57 and sodium adsorption ratio from 10.54 to 4.88 at the depth of 0-30 cm. The use of agricultural gypsum and washing in a saline soil of the pecan orchard improved soil chemical properties using 5 and 10 Mg ha-1.

AbstractTwelve carrot varieties in different colours and sizes were investigated for chemical properties (dry matter, ash, pectins, titratable acidity, and pH), contents of vitamin C, sugar, organic acids, mineral (sodium, potassium, calcium, iron, and magnesium), and anti-oxidant activities (ABTS, FRAP, and ORAC). Moreover, total polyphenolics and total tetraterpenoids of colourful carrot varieties were presented. According to the study, sucrose was the dominant sugar and isocitric acid was the most common organic acid in carrot samples. In the case of mineral content, potassium, sodium, calcium, magnesium, and iron were identified, while copper was not identified in carrots. Additionally, most of the analyzed carrots were a good source of pectins (average—1.3%), except for mini-orange carrot. Purple-coloured carrot samples demonstrated the highest results for total sugar (11.2 g/100 g fm), total organic acid (2.8 g/100 g fm), total polyphenolic contents (224.4 mg/100 g fm), and anti-oxidant activities (17.1 mmol Trolox equivalents/100 g dm). In turn, the lowest results were observed in normal yellow carrot for total polyphenols (7.3 mg/100 g fm), and anti-oxidant activities (2.5 mmol Trolox equivalents/100 g dm); besides, the lowest total tetraterpenoids were determined in micro-white carrot—0.2 mg/100 g fm.

Agricultural Operations

Precision farming involves the collection of detailed information about the characteristics of agricultural operations. Electro-conductivity (EC) of soil is one of the tests easier and less costly for agriculture, which can be performed today. Electro-conductivity (EC) is the ability of a material to transmit (conduct) an electrical current and is usually expressed in miliSiemens / meter (MS / m). Electro-conductivity (EC) of soil is a measurand that characterizes many soil properties which affect the productivity of crops. These include the water content, soil texture, soil organic matter (OM), depth to clay layer, the capacity of cation exchange (CEC), salinity, calcium, magnesium. Measurements of electro-conductivity (EC) of soil can add value to agricultural operations if they can be used to help explain variations in agricultural production. Article shows electro-conductivity maps models of the prepared soil in different locations in Romania and electro-conductivity correlation with the physico-chemical properties of these soils

Abstract-Oil and fats are important component of human dietary system. Increase in demand and different applications of oil foster the search for vegetable and seed oil of high quality. In India several regions have developed specific preference for edible oil locally available. Several pockets in Garhwal Himalayan region, people give preference to some wildly growing species. Prinsepia utilis(bhekal) is one of that kind. This paper deals with the investigation of physicochemical characteristics, fatty acids composition and mineral content seed oil of bhekal (P. utilis). Mature seeds were collected fromChakrataforestdivision,Chakrata,Uttarakhand,India and oil was extracted byconventional method. Extracted oil was yellow in colour, tasteless, odour less, soluble in benzene, pet-ether and slightly soluble in acetone. Its physico-chemical and proximate values were determined by appropriate lab method. The elements present in seed oil were also determined which reflect that oil is rich in Iron, Sodium, Potassium and appropriate range of Potassium, Zinc, Calcium and Magnesium which makeit suitable foredible consumption and commercial purposes. The composition of fatty oil was determined by Gas Chromatography (GCMS). From GCMS analysis the main constituents of oil such as Myristic acid (13.10%), Palmitic acid (10.20%), Stearic acid (21.90%) and Oleic acid (4.50%) were determined. Nutritional and physico-chemical properties of the Prinsepia utilisoil and their comparison with other food grade oil suggested that oil is suitable for use in domestic and for the industrial uses.

Microbiological Analyses

<p><em>Gundpak, </em>is a popular <em>khoa </em>based traditional milk product of Nepal and commonly used as a sweet. Twelve market samples of <em>Gundpak</em> were collected from the different areas of Kathmandu valley. The physico-chemical, sensory and microbiological analyses of the samples were investigated. The commercial samples were not consistent in their chemical compositions. The moisture, fat, protein, carbohydrates and ash were varied from 10.1 to 21.2, 10.6 to 16.5, 16.8 to 30.3, 29.0 to 54.8, 2.4 to 3.7 percentages, respectively. The microbiological analysis showed that <em>Total Plate Count, Yeast </em>and <em>Mold, and Coliform</em> were varied from 0 to 5 × 10<sup>4</sup>, 0 to 8.0 × 10<sup>3</sup>, 0-1.1 × 10<sup>2</sup>, whereas there was no growth of <em>Staphylococci</em>. The hardness, cohesiveness, gumminess, springiness, chewiness and adhesiveness values were varied from 31.7 to 245.3 N, 90.03 to 296.3, 7.84 to 22.06 N, 2.36 to 7.62, 1.45 to 16.2 N.mm, and 0.3 to 6.8 mNm, respectively, among the samples. In the commercial samples, colour parameter, L<strong><sup>*</sup></strong>values was varied from 17.12 to 42.08, indicating wide variations in appearance from light to dark brown. The overall sensory quality did not show significant variations. The minerals, calcium, magnesium, sodium, potassium, iron, zinc and copper were in the ranges from 390.7-527.15, 25.56-40.43, 188.86-215.93, 282.0-378, 0.41-0.52, 1.31-2.58 and 0.11-0.16 mg/100 g sample, respectively. These results indicated that Nepalese <em>Gundpak</em> significantly vary in physico-chemical characteristics and hence require optimization of product ingredients and processing technology to get uniform high quality.</p>

Fracturing under ultrahigh vacuum (UHV, p ≤ 10-9 Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite foe studies of interactions between condensing molecules is possible and surface forces are unequally distributed, the condensate will accumulate at places with high binding forces; crystallites will arise which may be useful a probes for surface sites with specific physico-chemical properties. Specific “decoration” with crystallites can be achieved nby exposing membrane fracture faces to water vopour. A device was developed which enables the production of pure water vapour and the controlled variation of its partial pressure in an UHV freeze-fracture apparatus (Fig.1a). Under vaccum (≤ 10-3 Torr), small container filled with copper-sulfate-pentahydrate is heated with a heating coil, with the temperature controlled by means of a thermocouple. The water of hydration thereby released enters a storage vessel.
