Since the economy is considered one of the areas necessary for the population to live and prosper, the existence of concepts related to this area becomes the public knowledge of every person. One of the main issues is the definition of the economic crisis and its causes, the urgency of anti-crisis measures. Not a single node, various attacks that have arisen in the global economy will bypass our country among many countries. It is important for everyone to know what measures have been taken to prevent this situation and what problems we face.

Iron deficiency leads to a weakening of plant growth and a decrease in their yield. A promising solution to this problem is the use of iron nanopowders, iron oxides as biostimulants for the growth of agricultural plants. However, the special properties of nanoparticles can enhance the mechanisms associated with toxic effects on living organisms and lead to microelementoses. The response of plants to the effect of iron is highly variable and depends on their genotype and species. Literature data on the effect of finely dispersed iron particles on the elemental composition of a plant of the species Triticum vulgare Vill (common wheat) are insufficient, in addition, the interaction of these particles with natural sorbents - humic acids, which control the bioavailability and transport of elements in natural objects, has not been practically studied. The article presents data on the content of toxic elements (Cd) in the aerial parts of Triticum vulgare Vill wheat plants grown in the soil under a single invasive effect of aqueous solutions of spherical nanoparticles of iron Fe0 (diameter 80 ± 5 nm), magnetite FeO (width 50– 80 nm and height 4–10 nm), ionic forms of di- and trivalent iron sulfate with the addition of humic acids isolated from brown coal of the Tyulganskoe deposit. When studying the dynamics of changes in the content of toxic elements, it was found that under the influence of iron and magnetite nanoparticles, the process of replacing more toxic mercury with less toxic cadmium is observed at a constant total amount, the use of ferric sulfate with a concentration of 0.0001 g/l for a single dose of -leaf of wheat Triticum vulgare Vill leads to the best result in reducing toxic elements (cadmium) in the aerial part of the plant.

The article describes the pasture capacity of the degraded semi-desert and desert zones of the Republic of Uzbekistan. As a result of continuous and intermittent use of pastures for many years, almost 10 million hectares of pastures are in varying degrees of degradation and productivity has declined significantly. Low productivity and severe overeating of fodder plants leads to overgrazing of pastures, i.e. per year, pasture capacity exceeds the allowable norm by more than 10 times. The main reasons for the decline in pasture productivity are: firstly, global climate change, drought; secondly, in the conditions of a growing number of livestock at the disposal of the population, the processes of pasture use are not regulated; thirdly, the system of animal husbandry that meets the new conditions has not been developed; fourthly, the types of plants popular on pastures have decreased, the role of which is assigned to other plant species of no economic importance; fifthly, this can be explained by insufficient attention to the organization of irrigation, melioration and seed production on pastures.
