STUDY OF THE PURCHASE OF DYE COMPOSITE MATERIALS BASED ON INORGANIC AND ORGANIC RAW MATERIALS

: the article states that one of the biggest problems of modern agriculture is to prevent the irreversible loss of fertile land on earth and to provide agriculture with new land. In this regard, it has become an urgent problem to use natural resources efficiently and restore damaged lands with various means and methods. In the studies conducted to solve the problem, the process of obtaining composite materials with fertilizer-ameliorant properties, which is of particular importance in increasing soil productivity and plant height, using inorganic and organic raw materials, was studied. It has been established that only applying fertilizers to ecologically damaged soils does not give positive results, because the structure and physical-chemical properties of the soils are damaged, and complex measures must be taken to restore them. The more intensive feeding of the plant with phosphorus with the participation of the magnesium element leads to the formation of water-resistant aggregates, which, as a result, percolation and infiltration decrease, and the amount of available phosphorus in the soil increases.

The 20th century brought new global ecological problems to mankind, such as the loss of land and the decrease in its fertility. The land is an independent private natural entity like plants, animals, water, and air. Sometimes he is subjected to terrible diseases -destruction and infertility. The most important part on which soil fertility depends is humus -organic matter. The most productive soils are soils with a humus content of 10-12%. One of the urgent questions of modern agrochemistry is the organization of the correct use of soil for humus preservation [1]. Humus in the soil, which has a total reserve of about 1.5 1018 g on the planet, is a reservoir of solar energy on the earth's surface. Without humus, the soil dies. If the soil is deprived of annual decaying plant residues, microorganisms will immediately switch to feeding on humus Content is licensed under the Creative Commons Attribution 4.0 license (CC-BY 4.0) and quickly destroy it. This is one of the biggest problems of modern agriculture.
Because the irreversible loss of fertile land on earth has reached 6-7 million hectares every year. To compensate for this loss, the same amount of new land should be brought into agriculture [2].
In this regard, the problem of effective use of natural resources is of great importance. Over the past 10 years, the idea of using various production wastes of industry and agriculture as raw materials for the purchase of valuable products has been developed, which is related to their low cost and solving environmental problems by efficient use of waste [3].It is considered more promising to carry out research mainly based on special environmentally friendly animal husbandry and various wastes of agriculture, resulting in the improvement of the physical and chemical properties of soils and vegetation [4].In the studies conducted for this purpose, the study of the process of obtaining composite materials with fertilizer-ameliorant properties, which is of particular importance in increasing soil productivity and plant height by using inorganic and organic raw materials, is one of the urgent problems. The main criterion for the evaluation of agricultural lands is their productivity.
According to agrochemical data, up to 80% of the lands of our Republic are salinized and unusable. They are mainly distributed in the Kura-Araz Plain, Absheron, Ordubad Plain, and Aran zone. In the territory of our republic, there are more than 1.3 million hectares of moderately and severely saline soils, the area of these areas is increasing every year, and the alarm should be sounded [6][7]. color and reproduction in plants, and in ensuring flowering and fruiting. It has been determined that as soil pH increases, it becomes more difficult for plants to absorb water. In boron-deficient soils, it is difficult to increase the height and productivity of plants. Planting and drought conditions should also be taken into account to assess the impact of boron.
In our research, to use the boron component, oil well water was used as a source of boron, as well as Dari-dough (Nakhchivan) thermal water, which contained a certain amount of boric acid due to the presence of 0.15-0.24% boron in the final product. The maximum permissible concentration for boron is 0.5 mg/l boron for different waters depending on the nature of economic use. In this regard, we first studied the composition of the main components of water. We used organic ion exchangers -hazelnut shell -which have better sorption capacity for cleaning the transition of boron from boron water to the composition of the composite material. Hazelnut shell consists of lignin (30.2%), cellulose (28.9%), hemicellulose (11.3%), tannin (18.2%), and proteins (6.7%).
Hazelnut shell has been proven to be an effective biological absorbent through research. experiment, the solution is filtered, the solid phase is dried at 95-100ºC, the pH of the liquid phase is checked and the liquid is used as a meliorate.
In general, when unburnt rocks are used during the decomposition of carbonate compounds with phosphoric acid, it takes a certain amount of time for the formation of a large amount of stable foam and its extinction, which slows down the rate of the decomposition reaction (30-120 minutes). When taking roasted raw materials, the resulting foam stays for 5-10 minutes. Therefore, dolomite is used as a carbonated raw material, in which stable foam formation is almost absent and the speed of the As a result of drying the received slag, a calcium-magnesium-boron-phosphorus composite material was obtained, the composition of which is shown in the above table   [Table 2].
