“…With eight-year irrigation, a reliable change in profile compaction can be traced to a depth of 60 cm and a decrease in porosity by 2.0%-2.2% in the upper horizons and by 4%-5% in the lower ones. The utmost decrease in porosity occurs at a depth of 40-70 cm, which is consistent with the results of the soil granulometric composition, indicating the maximum content of silt particles at the same depth (Suyundukov, 1995(Suyundukov, , 2001. Sugar beet responds to practices that contribute optimal indicators of soil density, making more demands on soil aeration (Uvarov et al, 2006).…”

“…In ordinary chernozems of the steppe Trans-Urals, long-term irrigation (14-15 years) led to the compaction of arable and sub-arable horizons. At the same time, its maximum value at a depth of 60-70 cm reached 1.51 g/cm 3 (Suyundukov, 1995(Suyundukov, , 2001. It was also long-established that the longer the irrigation period, the more compacted the arable horizon and the deeper this compaction manifests itself in the soil profile (Kukoba and Balyuk, 1983;Korolev et al, 2012).…”

This work studied the effect of irrigation and mineral fertilizers on the physical properties of light chestnut soil used in cultivating sugar beet (Beta vulgaris L.). The experiment happened in 2021 on an irrigated field with an area of 2 ha in the territory of the Kazakh Research Institute of Agriculture and Plant Growing, District Karasai, Almaty region, Kazakhstan. A sugar beet hybrid (obtained from domestic selection ‘Aksu’ and foreign selection ‘Yampol’) cultivation used four levels of mineral fertilizers, i.e., 0:0:0 (control), 90:90:60, 120:120:90, and 150:150:120 NPK kg ha-1. During the sugar beet growing season, all periods of observations recorded an increase in the bulk density in the upper, middle, and lower soil layers, from 1.14–1.27 g/cm3 to 1.31–1.48 g/cm3. The content of agronomically valuable aggregates in 0–10 cm, 10–20 cm, and 20–30 cm soil layers decreased from the germination phase to harvesting of sugar beet in extensive technology (10.0%–15.7%) and intensive technologies (2.3%–13.1%). In these soil layers, the number of water-stable aggregates decreased from the beginning of renewal to the end of the growing season of sugar beet in technology without the use of fertilizers (2.9%–6.4%) and in technologies with the application of mineral fertilizers (1.6%–7.6%). In the soil layers, the noted highest content of productive moisture occurred in the phase of closing the leaves in the rows with the extensive technology of sugar beet cultivation (51.5–213.2 mm). Irrigation during the sugar beet growing season reduces the content of agronomically-valuable and water-stable aggregates in soil layers to the minimum values for harvesting in technology without the use of fertilizers (50.5%–54.4% and 12.9%–14.2%) and technology with the use of mineral fertilizers (52.3%–54.4% and 10.9%–13.5%), respectively.
