“…In the arable layer of ordinary chernozems in the Saratov region, the total content of As and Hg was within 3.80-4.54 and 0.018-0.039 mg/kg [18], and in the Belgorod region, 4.10-7.13 and 0.015-0.035 mg/kg, respectively [16]. In various subtypes of chernozems of Central Siberia, the mean content of Hg was in the range of 0.019-0.029 mg/kg [5].…”

The results of state agroecological monitoring of soils conducted in the southwestern part of the forest-steppe zone of the Central Chernozem Region are analyzed. It was found that in the Aar layer of the arable chernozem in a typical forest-steppe zone of the Central Chernozem Region, the mean total contents of As and Hg are 4.18 and 0.022 mg/kg, respectively. In the parent rock (C), the content of As is 1.38 times higher, and Hg is 2.22 times lower than in the Aar layer. Organic fertilizers are the main source of As and Hg in the agroecosystems of the Belgorod region, but this does not pose a danger to soil pollution or crop production. The highest mean As content (0.020 mg/kg) was found in winter wheat, peas, and sunflower seeds, and the lowest (0.016 mg/kg) was in corn and soybeans. The highest Hg content was found in barley (0.006 mg/kg) and winter wheat (0.007 mg/kg), while the lowest content of this element (0.002 mg/kg) was found in sainfoin hay. No evidence of exceeding the maximum allowable concentration of As and Hg in food grains and the maximum allowable level in feed products was revealed in this study.

“…The use of bottom silts or sapropels has become widespread across the territories of many states. They are used as feed additives in poultry and animal husbandry as well as being used as additives in soil substrates [20][21][22][23][24][25][26]. Sapropel can also be part of the manufactured vermicompost, which is used as an additional food to increase the yield of agricultural plants by farmers [27,28].…”

This publication presents the results of studies of the bottom sediments (sapropels) of lakes in the North Kazakhstan region. The purpose of this study is to identify the possibility of using sapropels from the lakes of the region in obtaining innovative fertilizers for organic farming. For this purpose, geoinformation technologies, field research, statistics, and chemical and chemical-analytical methods were used (automated spectrometric methods of segmented flow analysis, photocolorimetry, flame photometry, and inductively coupled plasma atomic emission spectrometry). During the first stage of this study, the bottom sediments of three lakes in the region, which were at different stages of eutrophication, were selected to study the chemical composition of the raw materials. The sapropel of Lake Penkovskoye had optimal indicators. Further, an analysis of the territory of the region for the development of agrotourism was carried out. The aim of this study is to substantiate the prospects for the use of sapropel in the production of innovative fertilizers. The natural origin of sapropels allows them to be used in the production of environmentally friendly and safe products. Reducing the use of artificially synthesized mineral fertilizers will make agriculture and the environment safe and sustainable. This will further contribute to the development of agrotourism in the region.
