Smart technologies in our lives

Currently, significant reforms are being implemented in education of a strategic nature.  In our country, along with quality education, modern education of the younger generation is also considered important.  Taking into account the experience of developed countries, our respected President creates all opportunities for the healthy development of our youth physically and spiritually.

 Currently, all the latest scientific achievements are being implemented both in our country and in other countries of the world.  It is worth noting that digital technologies are being implemented in the education system.  With the expansion of science and economic power of any country, the level of its innovative development is assessed.  Today, in our country Turkmenistan, which is strengthening its position among the developed countries of the world, work is being carried out at a high pace on the innovative development of the country and its transition to a digital system.  Digital technologies are used in all economic systems.  At the basis of this activity, first of all, it should be noted that our President had high goals.

 Technology is an art whiçh is created by people for human use.  The word “Technology” comes from the Greek words techne (skill, skill, art) and logos (science).  Based on this, it can be noted that technology is the science of human activity.  Modern technology includes scientific knowledge and discoveries.  The main functions of the technology includes saving labour and resources (extracting steel from scrap metal, paper, etc.), conservation and information tasks.

 Smart technology is artificial intelligence created by humans that detects a need and addresses it using built-in functions.  Based on the phrase of scientists and inventors “Keep it simple, keep it simple!”  many smart technologies have been created.

 As an example of the above, calculators were the first smart technology developed.  In 1500, Peter Hahnlein, from Germany, invented the first small clock using a bead.  In 1762, John Harrison invented the pocket watch.  At the end of that century, wristwatches appeared, but mostly women wore them as bracelets.  But in 1904, aviator Alberto Santos Dunon invented the stopwatch to keep his hands free while flying.  As a result, the human body became the main place for attaching watches.  The first smart watches were created in 1975 by Hamilton Watch.  These calculator watches went down in history as the first smart watch.  From 1975 to this day, smart watches and other smart technologies have been created with many functions built into them.

The role of fertilizer chemistry in the intelligent specialization of the country's agricultural development.

1. Bulk chemical industry.More than 70 elements are found in plants, most of which are found in very small amounts. However, elements such as carbon, oxygen, hydrogen, nitrogen, phosphorus, sulfur, magnesium, potassium, and calcium are also abundant and essential for life. Plants can obtain nitrogen, phosphorus, and potassium (NPK) from the air and soil. However, these three elements (NPK) are supplied externally to the plants for good yield. Fertilizers are used to enrich the soil with NPK.Organic fertilizers. In them, nutrients are stored in substances of animal and plant origin. First of all, these fertilizers include manure, as well as various products of the processing of substances of animal and plant origin (peat, fish meal, feces, urban waste and various food wastes).Bacterial fertilizers - retain microorganisms that facilitate the accumulation of nutrients in the soil.2. Mineral fertilizers - products of inorganic origin, prepared by the industrial-factory method: chemical or mechanical processing of inorganic raw materials (for example, extraction of minerals - phosphorites, potassium salts, dolomites, etc., etc.). .). Mineral fertilizers obtained by chemical processing of raw materials differ in the concentration of active substances. Mineral fertilizers are divided into the following groups according to their active ingredients: nitrogen, phosphorus, potassium and micronutrients (boron, molybdenum, etc.).Along with the increasing demand for fertilizers, the production of NPK and NPK compounds has also increased. Many mineral fertilizers (for example: KCl, NaNO3, NH4NO3, etc.) contain only one nutrient. Such fertilizers are considered simple. Mineral fertilizers with two or three primary nutrients (NPK) in their composition are more complex. They belong to complex fertilizers.Air (raw material for nitrogen), phosphate rock (raw material for phosphorus) and sylvinite (raw material for potassium) are used as the main raw materials for fertilizer production.Elements   Duty NitrogenIt is stored in proteins. Deficiency causes slow growth..PhosphorusIt is stored in the composition of nucleic acids. It is necessary for the growth of roots. It helps in energy exchange during exposure.PotassiumAccelerates photosynthesis. Increases hydrocarbon production..The main functions of N, P and K elements as fertilizers Fertilizers are divided into simple and complex fertilizers according to the nutrients stored in the system. Simple fertilizers include nitrogen, phosphorus and potassium fertilizers. Simple nitrogen fertilizers include ammonium nitrate NH4NO3, urea (NH2)2CO and others. Simple superphosphate Ca(H2PO4)2•2CaSO4, double superphosphate Ca(H2PO4)2 and others are simple phosphorus fertilizers. Simple potassium fertilizers include potassium sulfate K2SO4 and others.
