Fertilizers are usually directly applied to soil, and also sprayed on leaves ('foliar feeding'). 4 Copyright © Tarek Kakhia. All rights reserved. http://tarek.kakhia.org ADANA UNIVERSTY – INDUSTRY JOINT RESEARCH CENTER Fertilizers are roughly broken up between organic and inorganic fertilizer, with the main difference between the two being sourcing, and not necessarily differences in nutrient content. Organic fertilizers and some mined inorganic fertilizers have been used for centuries, whereas chemically-synthesized inorganic fertilizers were only widely developed during the industrial revolution. Increased understanding and use of fertilizers were important parts of the pre-industrial British Agricultural Revolution and the industrial green revolution of the 20th century. 2 - Plant nutrients supplied by fertilizers Tennessee Valley Authority: "Results of Fertilizer" demonstration 1942 Fertilizers typically provide, in varying proportions: the three primary macronutrients: nitrogen, phosphorus, and potassium. the three secondary macronutrients such as calcium (Ca), sulfur (S), magnesium (Mg). and the micronutrients or trace minerals: boron (Bo), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo) and selenium (Se). The macronutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.2% to 4.0% (on a dry 5 Copyright © Tarek Kakhia. All rights reserved. http://tarek.kakhia.org ADANA UNIVERSTY – INDUSTRY JOINT RESEARCH CENTER matter weight basis). Micronutrients are consumed in smaller quantities and are present in plant tissue in quantities measured in parts per million (ppm), ranging from 5 to 200 ppm, or less than 0.02 % dry weight. 3 - Labeling of fertilizers: 3 – 1 - Macro nutrient fertilizers; Macronutrient fertilizers are labeled with an NPK analysis and also "N-P-K-S" in Australia . An example of labeling for the fertilizer potash is composed of 1:1 potassium to chloride or 52 % potassium and 48% chlorine by weight (owing to differences in molecular weight between the elements). Traditional analysis of 100g. of KCl would yield 60g. K2O. The percentage yield of K2O from the original 100g. of fertilizer is the number shown on the label. A potash fertilizer would thus be labeled 0-0-60, not 0-0-52. 4 - History of fertilizer While manure, cinder and iron making slag have been used to improve crops for centuries, use of inorganic artificial fertilizer is one innovations of the 19th century Agricultural Revolution. 5 - Inorganic fertilizer (synthetic fertilizer): Fertilizers are broadly divided into organic fertilizers (composed of enriched organic matter- plant or animal), or inorganic fertilizers (composed of synthetic chemicals and / or minerals). Inorganic fertilizer is often synthesized using the Haber-Bosch process, which produces ammonia as the end product. This ammonia is used as a feedstock for other nitrogen fertilizers, such as anhydrous ammonium nitrate and urea. These concentrated products may be diluted with water to form a concentrated liquid fertilizer (e.g. UAN). Ammonia can be combined with rock phosphate and potassium fertilizer in the Odda Process to produce compound fertilizer. 6 Copyright © Tarek Kakhia. All rights reserved. http://tarek.kakhia.org ADANA UNIVERSTY – INDUSTRY JOINT RESEARCH CENTER The use of synthetic nitrogen fertilizers has increased steadily in the last 50 years, rising almost 20-fold to the current rate of 1 billion tonnes of nitrogen per year. The use of phosphate fertilisers has also increased from 9 million tones per year in 1960 to 40 million tonnes per year in 2000. A maize crop yielding 6-9 tones of grain per hectare requires 30 – 50 kg of phosphate fertilizer to be applied, soybean requires 20 - 25kg per hectare.

One study has shown that application of nitrogen fertilizer on off - season cover crops can increase the biomass ( and subsequent green manure value ) of these crops, while having a beneficial effect on soil nitrogen levels for the main crop planted during the summer season. 7 Copyright © Tarek Kakhia. All rights reserved. http://tarek.kakhia.org ADANA UNIVERSTY – INDUSTRY JOINT RESEARCH CENTER 5 – 2 - Problems of inorganic fertilizer: 5 – 2 – 1 - Trace mineral depletion; Many inorganic fertilizers do not replace trace mineral elements in the soil which become gradually depleted by crops. This depletion has been linked to studies which have shown a marked fall (up to 75 % ) in the quantities of such minerals present in fruit and vegetables. However, a recent review of 55 scientific studies concluded "there is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs" [9] Conversely, a major long-term study funded by the European Union[10][11] [12]found that organically - produced milk and produce were significantly higher in antioxidants (such as carotenoids and alpha - linoleic acids) than their conventionally grown counterparts. In Western Australia deficiencies of zinc, copper, manganese, iron and molybdenum were identified as limiting the growth of broad- acre crops and pastures in the 1940s and 1950s , Soils in Western Australia are very old, highly weathered and deficient in many of the major nutrients and trace elements . Since this time these trace elements are routinely added to inorganic fertilizers used in agriculture in this state. 5 – 2 – 2 - Over fertilization ( Fertilizer burn ): Fertilizer burn 8 Copyright © Tarek Kakhia. All rights reserved. http://tarek.kakhia.org ADANA UNIVERSTY – INDUSTRY JOINT RESEARCH CENTER Over-fertilization of a vital nutrient can be as detrimental as under fertilization."Fertilizer burn" can occur when too much fertilizer is applied, resulting in a drying out of the roots and damage or even death of the plant. 5 - 2 – 3 - High energy consumption:

B.Sc., Chemistry Syllabus - CBCS Scheme 2018-19 onwards. Page 1 PREAMBLE For the development of any Society, Science education plays an important role. Chemistry, being a major component of Science, is one of the increasingly important disciplinary areas of Science. Chemistry, which is also studied at the Bachelor’s degree programme for years, has been witnessing a slow transition from an analog to a much- needed one. It is an experimental science and students need to be trained both in the theoretical & practical aspects to get expertise. Moreover, the topics prescribed should provide in-depth knowledge of the subject and also the relevant basic allied subjects. Under this context, in order to make the U. G. teaching more effective and meaningful, revamping the syllabus is the need of the hour. It is certain that systematic and planned curricula from first to the third year shall motivate and encourage students for pursuing higher studies in various disciplines of chemistry such as Inorganic, organic, Physical, Analytical and Bio-Chemistry. This curriculum also enables the students to shoulder the responsibility as chemists in chemical industry. Thus, an updated and content revision of UG Chemistry syllabus is essential to improve its quality at the National and International level and also to meet the present-day challenges of PG and research oriented work after the PG programme.

Dulieu2 1 Aix Marseille Univ, CNRS, CNES, LAM, Marseille, France e-mail: [email protected] 2 CY Cergy Paris Université, Observatoire de Paris, PSL University, Sorbonne Université, CNRS, LERMA, F-95000, Cergy, France 3 Max-Planck-Institut für extraterrestrische Physik, Gießenbachstraße 1, Garching, 85748, Germany Received –; accepted – ABSTRACT Context. The nitrogen reservoir in planetary systems is a long standing problem. Part of the N-bearing molecules is probably incor- porated into the ice bulk during the cold phases of the stellar evolution, and may be gradually released into the gas phase when the ice is heated, such as in active comets. The chemical nature of the N-reservoir should greatly influence how, when and in what form N returns to the gas phase, or is incorporated into the refractory material forming planetary bodies. Aims. We present the study the thermal desorption of two ammonium salts: ammonium formate and ammonium acetate from a gold surface and from a water ice substrate. Methods. Temperature-programmed desorption experiments and Fourier transform infrared reflection spectroscopy were conducted to investigate the desorption behavior of ammonium salts. Results. Ammonium salts are semi-volatile species releasing neutral species as major components upon desorption, that is ammonia and the corresponding organic acid (HCOOH and CH3COOH), at temperatures higher than the temperature of thermal desorption of water ice. Their desorption follows a first-order Wigner-Polanyi law. We find the first order kinetic parameters A = 7.7 ± 0.6 × 1015 s−1 −1 20 −1 −1 and Ebind = 68.9 ± 0.1 kJ mol for ammonium formate and A = 3.0 ± 0.4 × 10 s and Ebind = 83.0 ± 0.2 kJ mol for ammonium acetate.

Shale gas is present in hydrocarbon rich shale formations. Shallow gas is commonly defined as gas occurrences in unconsolidated sediments of Tertiary age (often down to depths of 1000 m below surface). The occurrences are positively associated with thick Neogene sediments and are often trapped in anticlinal structures associated with rising salt domes (Muntendam-Bos et al, 2009). Shale has low matrix permeability, so gas production in commercial quantities requires fractures to provide permeability.

It has been subjected to the Agency's peer and administrative review, and has been approved for publication. Mention of trade names of commercial products does not constitute endorsement or recommendation for use. ii ABSTRACT SPARC (SPARC Performs Automated Reasoning in Chemistry) chemical reactivity models were extended to calculate hydrolysis rate constants for carboxylic acid ester and phosphate ester compounds in aqueous non- aqueous and systems strictly from molecular structure. The energy differences between the initial state and the transition state for a molecule of interest are factored into internal and external mechanistic perturbation components. The internal perturbations quantify the interactions of the appended perturber (P) with the reaction center (C). These internal perturbations are factored into SPARC’s mechanistic components of electrostatic and resonance effects. External perturbations quantify the solute-solvent interactions (solvation energy) and are factored into H-bonding, field stabilization and steric effects. These models have been tested using 1471 reliable measured base, acid and general base-catalyzed carboxylic acid ester hydrolysis rate constants in water and in mixed solvent systems at different temperatures.

  • Flight Through the Comet Chury's Dust Cloud Resolves Chemical Mystery 21 January 2020
    Flight through the comet Chury's dust cloud resolves chemical mystery 21 January 2020 em. Hans Balsiger, was on board. A key finding from the measurements taken by this instrument was that there appeared to be a lack of nitrogen in Halley's coma—the nebulous covering of comets which forms when a comet passes close to the sun. Although nitrogen (N) was discovered in the form of ammonia (NH3) and hydrocyanic acid (HCN), the incidence was far removed from the expected cosmic incidence. More than 30 years later, researchers have solved this mystery thanks to a happy accident. This is a result of the analysis of data from the Bernese mass spectrometer ROSINA, which collected data on the comet 67P/Churyumov-Gerasimenko, called Chury for short, on board the ESA space probe Rosetta (see info box below). Risky flight through the comet Chury's dust cloud Less than a month before the end of the Rosetta A plume of dust from Comet mission, the space probe was just 1.9 km above 67P/Churyumov–Gerasimenko, seen by the OSIRIS Wide Angle Camera on ESA's Rosetta spacecraft on 3 the surface of Chury as it flew through a dust cloud July 2016. The shadow of the plume is cast across the from the comet. This resulted in a direct impact of basin, which is in the Imhotep region.
