“…Therefore, when determining the watering of an apple orchard, it is necessary to consider such factors as the depth of the moistened soil layer, humidity, density, precipitation, minimum soil moisture [10]. Thus, the number of preirrigation and irrigation norms was determined by the formula, [11] (1):…”

Based on the increasing efficiency and productivity of water resources by improving the technique and technology of intensive drip irrigation of apple orchards, calculations were presented on the formation of a moisture contour by drip irrigation for apple seedlings and seedlings of low-growing fruit-bearing apple orchards in the conditions of the foothill zone of the Zhambyl region, the justification of the intensity and time of water supply, the placement of the number of droppers providing moisture to the root layer of apple trees grown to maintain humidity in accordance with 0.8 MC in the foothill zone of the Zhambyl region on light grey soils with insufficient natural humidity. As the apple trees grow and develop, the need to moisten the root layer along the drop line increases until the wet contour is completely covered. It is established that during mass watering of apple orchards, the regularities of the process and dynamics of soil moistening are established depending on the value of the irrigation rate. With drip irrigation, the root layer of the soil is compacted.

“…Uranium, thorium, and radium can enter plants through phosphorus mineral fertilizers and from the atmosphere in areas with significant coal combustion. Stable strontium enters the landscape with simple superphosphate and phosphogypsum [47,48]. Noticeable environmental contamination with copper is observed in regions with intensive vineyard cultivation, where this element is widely used to combat diseases affecting these crops.…”

Significant environmental concerns are raised by heavy metal pollution in soils, particularly in areas like South Kazakhstan where hazardous materials have accumulated as a result of human activities including mining, industry, and agriculture. This paper presents theoretical and experimental findings regarding the phytoremediation potential of sowing peas (Pisum sativum) in the grey soils of South Kazakhstan. Special attention is paid to the determination of gross concentrations of various forms of copper, nickel, and cobalt in the initial and remediated soils. The methodology basis for the study were chemical phase analysis, atomic absorption spectrometry, and X-ray electron microscopy to assess heavy metal levels in soils and plant samples. It was established that in the arid climate of Southern Kazakhstan, the upper layers of the soil up to 40 cm contain the highest concentration of heavy metal ions. The findings of the study will allow predicting the effectiveness of phytoremediation measures. The study suggests that sowing peas have potential for phytoremediation due to their ability to accumulate heavy metals in their root systems and biomass. It highlights the potential of phytoextraction techniques, which involve growing metal-accumulating plants in polluted soils and processing the harvested biomass to recover absorbed metals.

Streptomycetes produce a huge variety of bioactive metabolites, including antibiotics, enzyme inhibitors, pesticides and herbicides, which offer promise for applications in agriculture as plant protection and plant growth-promoting products. The aim of this report was to characterize the biological activities of strain Streptomyces sp. P-56, previously isolated from soil as an insecticidal bacterium. The metabolic complex was obtained from liquid culture of Streptomyces sp. P-56 as dried ethanol extract (DEE) and possessed insecticidal activity against vetch aphid (Medoura viciae Buckt.), cotton aphid (Aphis gossypii Glov.), green peach aphid (Myzus persicae Sulz.), pea aphid (Acyrthosiphon pisum Harr.) and crescent-marked lily aphid (Neomyzus circumflexus Buckt.), as well as two-spotted spider mite (Tetranychus urticae). Insecticidal activity was associated with production of nonactin, which was purified and identified using HPLC-MS and crystallographic techniques. Strain Streptomyces sp. P-56 also showed antibacterial and antifungal activity against various phytopathogenic bacteria and fungi (mostly for Clavibacfer michiganense, Alternaria solani and Sclerotinia libertiana), and possessed a set of plant growth-promoting traits, such as auxin production, ACC deaminase and phosphate solubilization. The possibilities for using this strain as a biopesticide producer and/or biocontrol and a plant growth-promoting microorganism are discussed.
