“…Amonificators are the most represented group of microorganisms in the soil (Rasulić et al, 2021). A significantly greater number of amonificators was recorded in the rhizosphere of compactum wheat than in the rhizosphere of the cultivars of common, durum and spelt wheats.…”

“…This occurs as a result of the synthesis and export of organic compounds such as phytohormones (e.g., indole-3-acetic acid) that enhance root growth and through a contribution of biological nitrogen fixation to nitrogen acquisition by the plant (Venieraki et al, 2011). Oligonitrophilic bacteria represent a specific group of microorganisms capable of reducing the molecular form of nitrogen from the atmosphere and converting it into the organic ammonia form, using very small quantities of mineral nitrogen content from soil (Rasulić et al, 2021).…”

The rhizosphere is a dynamic environment in which many parameters may influence biogenicity. The important factors determining the microbial community in the rhizosphere are plant and soil nutrient supply. The aim of this paper was to determine the abundance of basic microbiological groups in the rhizosphere of four wheat subspecies, in three fertilization treatments in the organic farming system. A field experiment was conducted using a randomized complete block design with four replicates. It was carried out on the leached chernozem soil type. There was significant variability in the abundance of the studied physiological groups of microorganisms between the wheat subspecies, as well as between the fertilization treatments. The rhizosphere of common wheat had the greatest abundance of fungi (24.37 x 103 g-1). The rhizosphere of compactum wheat had the largest abundance of oligonitrophilic bacteria (361.47 x 105 g-1) and amonificators (119.27 x 105 g-1). There were no significant differences in the abundance of actinomycetes between the cultivars of common, compactum and durum wheat, but their lowest number was found in the spelt wheat cultivar (11.25 x 103 g-1). The combined application of biofertilizer and organic fertilizer resulted in a significantly greater abundance of amonificators (56.6%), fungi (28.2%) and oligonitrophiles (14.6%) than in the control treatment. The results show that the crop variety and application of appropriate fertilizer formulations can influence the abundance of the studied groups of microorganisms. This is particularly the case in organic farming, which relies completely on natural resources and processes.

“…Amonificators include a large group of bacteria, fungi and actinomycetes that transform proteins and other organic nitrogen compounds, releasing ammonia. Amonificators are the most represented group of microorganisms in the soil (Rasulić et al, 2021). Amonificators are very important in soil ecosystem, as well as nitrogen fixators.…”

The number, activity and diversity of microorganisms define the level of biogenicity and indicate the quality and health of the soil. The abundance and structure of microbial communities vary in different types of soils, so in order to preserve and protect natural and agroecological systems, in addition to physical-chemical analyses, monitoring of dynamics of microbiological activity in agricultural and non-agricultural soil is also necessary. Each type of soil has its own characteristic micro biocenosis, and different methods of soil use can have a positive or negative impact on microbiological activity, which directly affects the fertility of the soil. Soil bacteria are very important in biogeochemical cycles, and biological nitrogen fixation plays an important role in nitrogen cycling by transferring atmospheric dinitrogen into the soil. It is performed by symbiotic and asymbiotic nitrogen-fixing microorganisms, called nitrogen fixators. Amonificators are bacteria that play a very important role in soil ecosystem, as well as nitrogen fixators. This group of bacteria participates in the processes of protein decomposition and transformation. The aim of the paper is to indicate, based on the presence of nitrogen fixators and amonificators in soil under ashes, the biogenicity of this soil at four different localities: pure ashes, soil under ashes covered with herbaceous vegetation, soil under ashes covered with wood vegetation and agricultural soil, and to give advice on future activities regarding recultivation of these types of soil under ashes. The results of the research showed that microorganisms are mostly represented in different numbers in the tested soils, which indicates variations on the soil biogenicity and quality.
