“…For this reason, powdered peat-humic fertilizers as well as sodium or potassium ballast-containing humates can be produced as an initial product in demand. They are recommended to be used for organic agriculture, improvement of soil fertility, combating desertification of territories, solving problems on environment protection and other directions [19][20][21][22][23][24]. For this purpose, pre-dried (w = 16-25%) peat is sent for fine grinding to a ball mill.…”

The method of hydrophobic modification of dispersed materials is based on the extraction of bituminous components of peat and applying them to a treated surface. The industrial implementation of this method is possible in the following main directions. First, it is the thermochemical treatment in a reactor of the entire material volume by hydrophobic components of peat with a low concentration. Second, it is the obtaining of concentrated hydrophobically-modifying compositions and their use in the production technology of various types of powdered dispersed materials. Positive results were obtained with organo-mineral hydrophobically- modifying concentrates based on peat with clinker, kaolin, chalk, lime, vermiculite. Third, it is the use of the sorption properties of the porous structure of peat to saturate it with additional hydrophobic components: bitumen, oleic acid, organosilicon compounds, etc. The main advantage of the obtained composite hydrophobic modifiers is quality (accurate) dosing. There are promising directions of the use of hydrophobically-modifying additives in the construction industry, chemical industry and to ensure fire safety. A block diagram of the technological process of complex peat processing to produce hydrophobic and hydrophilic powders is proposed. Additional processing of production wastes allows for the production of a stabilizing additive for asphalt concrete.

“…Substrates often have inconsistent physical properties because their different components are derived from various sources and show different attributes (Lishtvan, et al, 2017). Therefore, choosing an adequate material is essential for the development of plants and this can contribute to reducing the negative effects of ecophysiological stress during the production of seedlings and after their transplantation.…”

One of the difficulties in the kale seedlings production in containers is to ensure the production of aboveground biomass with a limited portion of roots, restricted to a small volume of substrate. Thus, we investigated whether substrates with organic compost added to it associated with kale cultivars interfere in the quality of seedlings produced in a greenhouse. Here, we studied two kale cultivars and five substrates. The experiment was designed in randomized blocks, with treatments arranged in a bifactorial scheme (2 x 5), with three replications. We carried out the physical and chemical characterization of the substrates and evaluated attributes of the aerial part and root system of the kale seedlings. The results showed that the substrate with the highest water retention was the one without the addition of organic compost. The greater the proportion of organic compound added to the substrate, the higher the nitrogen, phosphorus and organic carbon values. Seedlings produced in the substrate with greater water retention capacity had better performance in relation to the morphology of the aerial part and the morphology of the root system. We conclude that seedlings of kale cultivars associated with substrates with higher water retention have better quality. Seedlings of the ‘Gaudina’ cultivar stand out for their better phytometric morphology, while seedlings of the ‘Manteiga’ cultivar have higher quality of root biomass.

In agricultural production, soil fertility and the overall productivity of arable land depends on the quality and quantity of mineral and organic fertilizers. The decrease in the humus content in soil observed over the past decade requires a systematic use of various organic fertilizers. The use of peat-based fertilizers guarantees high and sustainable crop yields. Restoration of soil fertility should be carried out by organic fertilizers enriched with humic acids with physiologically active groups, free nitrogen-containing components, a complex of nutrients and micro elements. The author considers the possibility of using humus peat ameliorants for the restoration of disturbed lands and the increase of soil fertility. The production and use of peat-based organic fertilizers and ameliorants in various sectors of the economy is an incentive for the stable functioning of the peat business and a significant factor in the socio- economic development of the regions of the Russian Federation.
