“…Furthermore, O.V. Pikovska (2012) proves that ploughing can lead to moisture loss due to decreased soil permeability, resulting from the destruction of soil structure and the formation of a hardpan after some previous crops. On the other hand, surface tillage (such as mulching) can help retain moisture in the soil by reducing evaporation and protecting it from wind and sunlight.…”

The unstable yield of agricultural crops arises due to insufficient soil moisture supply at crucial moments of plant emergence and growth, complicating agriculture and exposing it to the risk of crop losses. The purpose of the study is to determine the impact of the soil tillage system and previous crops on the productivity of spring barley plants. This was a long-term stationary experiment (2021-2023) with the application of statistical data processing. The influence of four previous crops was investigated – grain maize (control), soybeans, winter rapeseed, and sunflower – and three main soil tillage methods. It is established that the highest significant moisture reserves in the 0-100 cm soil layer at the sowing period were formed when spring barley was placed after soybeans, exceeding the control variant (grain maize) by 3.2 mm in 2021, 3.6 mm in 2022, and 3.4 mm in 2023, and after winter rapeseed by 8.5 mm, 6 mm, and 5.7 mm, respectively, over the years. The use of shallow no-till cultivation provided an advantage over the control (ploughing) in all years of observation: by 2.2 mm in 2021, 1.8 mm in 2022, and 8.8 mm in 2023. During the sowing period of the studied crop, the control surpassed only surface no-till cultivation by 2.7 mm in 2022. The optimal option should be considered the combination of soybeans as a previous crop with shallow no-till soil cultivation at 14-16 cm, which ensured moisture reserves during the earing period of the crop in 2021 – 75.1 mm, in 2022 – 93.2 mm, and in 2023 – 92.2 mm, and at the time of harvest, these indicators were 60.7 mm, 67.3 mm, and 60.0 mm, respectively. The grain yield of spring barley under this option was the highest in the experiment, averaging 7.26 t/ha, which is 27.3% higher than the control. The results of the study can be used to realise the genetic potential of spring barley plants to form stable productivity

“…Such research is critical for developing conservation strategies and understanding the dynamic interplay between lichens and their environments on a global scale. The study also underscores the pressing need to investigate aridification within this context, as arid conditions can significantly impact lichen populations and their responses to environmental changes (Pikovska, 2020;Zhumadilova et al, 2023). Understanding how aridification affects lichens globally is crucial for a comprehensive assessment of their ecologi-cal role and the development of effective conservation strategies.…”

The global diversity of approximately 25,000 lichen species (e.g., from the genera Usnea, Cladonia, and Peltigera), including rare and endangered ones, highlights the importance of preserving their population in the State National Nature Park “Burabay”. The objective of this study was to investigate the distribution of rare lichen species in the territory of the State National Nature Park “Burabay,” located in the Akmola region of Kazakhstan, in the period from 2018 to 2022, with a particular focus on understanding how aridification may have influenced their presence and abundance. In the course of the study, methods such as route expeditions, the comparative morphological method, as well as some other special methods were used. The collection of information to systematize the taxonomic composition of lichens (genera Lobaria, Rhizocarpon, and Xanthoria) was carried out during route expeditions. The study identified 56 lichen species, with a focus on rare and protected species. Established in 2000, the park's rich biodiversity is showcased, including the discovery of three very rare species (Dermatocarpon miniatum, Psora lurida, and Verrucaria nigrescens) and four species requiring protection (Peltigera spuria, Cladonia coccifera, Haematomma ventosum, and Caloplaca aurantiaca). These findings are significant, considering the absence of data on these species since the 1982 Red Book of Kazakhstan (including genera such as Lecanora, Lecidea, and Pertusaria). The sensitivity of lichens to environmental changes (indicated by genera like Alectoria, Bryoria, and Cetraria) makes them ideal for monitoring ecological health through a cost-effective method known as lichen indication. The increase in the species count over the past five years (highlighting genera such as Stereocaulon, Solorina, and Thamnolia) suggests effective conservation efforts and underlines the park's ecological importance. The study's findings reveal that aridification is reshaping lichen communities in the park, emphasizing their sensitivity to climate change and the need for conservation strategies to address these changes and ensure the preservation of lichen biodiversity in the face of global climate change. The research contributes valuable data for future conservation planning and environmental assessments in the region, emphasizing the need to protect diverse lichen genera (e.g., Evernia, Ramalina, and Parmotrema) for ecological monitoring and conservation.
