“…Safflower has a high heat resistance, which allows it to be freely cultivated in the dry steppe zone conditions [14 -18]. This crop characterized also by the ability to produce stable crops on unproductive including saline soils [15,16]. Safflower also used for the remediation of soil fertility due to its phytomeliorative properties [19,20].…”

The requirement of safflower (Carthamus tinctorius L., variety Alexandrite) for 14 nutrients was studied by the method of plants functional diagnostics. The possibility of using this method of plants functional diagnostics for assessing the state of plants, as well as assessing the ecological state was shown. This method is based on the chloroplasts suspension photochemical activity. It was found that the studied safflower is deficient in such mineral elements as Zn, Mg, Cu, Mo, N, KS. Doses for foliar feeding were determined based on the results of functional diagnostics. Functional diagnostic methods make it possible to assess the plant's requirement for a particular nutrient element, and not their content in the plant. The requirement of plants for elements can be estimated by controlling the intensity of physiological and biochemical processes. This method can be attributed to the main control tools in agriculture, which allows to control the crop yields. Because only with a constant supply of the necessary nutrients in optimal proportions throughout the growing season is it possible to maximize the use of the biological potential of plants. The use of plants functional diagnostic leads to a reduction in unproductive costs and the greening of agriculture. The data obtained by this method can be useful in a complex assessment of the ecological state of the environment.

“…It is known that due to catastrophic changes in ecosystems, the global consequences of intensive land use, leading to soil degradation, it is required to improve agricultural production. The solution of the global environmental problem of land degradation is possible through the use of non-traditional soil ameliorants [1][2][3][4], but due to the lack of scientific and industrial infrastructure in the field of processing, recycling and disposal of waste, technologies for the secondary use of resources are practically not used. Bottom sediments are sediments that cover the bottom of a water body.…”

The chemical composition of the bottom sediments of the Volga-Akhtuba floodplain was assessed. Chlorides (36 mg/kg) were found to be one of the predominant anions, while calcium (27 mg/kg) and sodium (27 mg/kg) were the predominant cations. In terms of pH, the bottom sediments were weakly alkaline throughout the studies. The agrochemical composition of bottom sediments of the studied water body corresponded to lime sapropel due to the content of organic matter in them (4.21%), as well as common forms of nitrogen (0.58%), phosphorus (0.27%) and potassium (1.1%). To assess the chemical and toxicological parameters in samples of bottom sediments, the quantitative content of metals and pesticides was determined. It was found that their content does not exceed the maximum permissible concentrations. An analysis of the IR spectrum data made it possible to establish that the IR spectrum contains absorption bands characteristic of bentonite clays, which have good fertilizing and water-retaining properties.

“…Currently, there are many different types of disks with different design and geometric parameters. Disc tillage implements differ in the shape of the working parts and the shape of the blade; installation method on the shaft; type of location on the frame and rack [12]. To improve agrotechnical performance and reduce energy costs when cultivating the soil, each disc is located on an individual rack.…”

Currently, there are a large number of tillage disc working tools. The article provides a detailed analysis of their designs. The main disadvantage of all structures is slippage during its interaction with the soil, which greatly reduces the quality of tillage. To eliminate this drawback, a new design of a soil-cultivating disc-pin working body was developed. The purpose of this study was to study the kinematics of a soil-cultivating disc-pin working body to ensure uniform operation without slipping. The rotation of the disk is ensured by a pin drum. During the forward movement of the trolley, the pins enter the soil, engage with it and turn the pin drum until, due to this rotation, they come out of the soil. A mathematical model of the movement of the ends of the pins in the plane of motion and taking into account the angle of attack has been compiled. Based on kinematics studies, the main parameters of the disc-pin working body are substantiated, the performance of which has been confirmed experimentally.
