“…Najveća vrednost labilne OM (458 µg g -1 ) zabeležena je kod varijante (T+G) 50N na dubini od 0-20 cm, dok je najmanja (219 µg g -1 ) utvrđena na istoj varijanti samo na dubini od 20-40 cm. Dobijene vrednosti se mogu dovesti u vezu sa stabilizacijom labilne OM (Liu et al, 2018) i manjom mikrobiološkom aktivnošću u dubljim slojevima zemljišta (Stamenov et al, 2016). Razlog za povećanje sadržaja labilne OM u površinskom sloju zemljišta ogledao se i u predusevu i učestaloj obradi zemljišta tokom jesenjeg i prolećnog perioda u cilju zaoravanja žetvenih ostataka (jesen) i zelenišnog đubriva (proleće).…”

In the agroecological conditions of Vojvodina, there is not enough research on the influence of plowing cover crops as a green manure on the content of labile organic carbon soluble in hot water (HWOC). The aim of the study was to determine the influence of crop rotation of different species of winter cover crops (CC) and spring crops in the subsequent sowing period (corn, soybeans and Sudan grass) on the content of organic matter (OM) levels as well as the dynamic of labile OM. Research was carried out at the Rimski Šančevi experimental station under Chernozem soil type. The winter CC consisted of the combined intercrops: winter pea (Pisum sativum ssp. Arvense L.) + triticale (×Triticosecale Wittm. ex A. Camus) (PT) and single-species CC winter pea (P) and control (without CC). Plowing of CC and control plots was carried out at a depth of 27 cm in the last decades of May 2018, and the sowing of maize, soybean and Sudan grass in early June with addition of 50 kg N ha-1 . Sampled was done in October at depth of: 0-20 cm, 20-40 cm. The analysis of variance determined a significant effect of cultivated crops (maize, soybeans and Sudan grass) in the subsequent sowing period on the changes of the HWOC content, as well as the interaction of cover crops and fertilization. The highest value of HWOC was measured in maize (658 µg g-1 ) on the variant P N0 (0-20 cm), and the lowest in the Sudan grass P N50 (20-40 cm). The highest share of HWOC in the total OM content was found in maize (2.56%), while the lowest share was measured in Sudan grass (1.87%).

“…The abundance and enzymatic activity of microorganisms are highest in the surface layer of the soil, in the phase of intensive plant grow, while at the end of the vegetation period, the abundance and enzymatic activity of microorganisms decrease. The abundance of microorganisms in the soil also depends on the presence and nature of organic matter, methods of processing, fertilization and plant cover (Bolton er al., 1984;Stamenov et al, 2016.). The number of microorganisms also depends on a number of abiotic factors such as pH, temperature, soil moisture, the presence of heavy metals, pesticides and other harmful substances (Jemcev and Đukić, 2000).…”

The most common type of soil in the valleys of large lowland rivers is Fluvisol or Alluvial soil. In order to determine the biogenity of this type of soil along the Western Morava basin, the representation of the total microflora, fungi, actinomycetes, ammonifiers, Azotobacter sp. and oligonitrophiles was examined. The samples were taken from soils used in the most common two different ways (plough fields and meadows). For that were used standard microbiological methods of inoculation a certain decimal dilution on appropriate nutrient media. No correlation was established between the number of examined groups of microorganisms and the way of land use, nor was there a correlation with chemical properties, primarily with pH and organic matter content. A good representation of Azotobacter sp., as an indicator of soil fertility, was found. Agrochemical analyses showed an acidic to neutral reaction, a low to medium percentage of organic matter, a very low to very high content of easily available phosphorus and easily available potassium.

“…The practices affect the distribution and supply of soil nutrients by directly altering soil properties and thereby influencing biological transformations in the rooting zone [9]. Influence of management practices on the size, composition, and function of the soil microbial communities varies greatly depending on their interaction with other abiotic and biotic factors, such as soil type, plant species, and other environmental variables [10]. Alterations in the physical and chemical nature of the soil may lead to change in soil microbial community, number and changes in microbial function [11].…”

Microorganisms are of primary importance for soil quality and natural productivity. Four land use systems viz., Forestry, Horticulture, Agriculture and Pasture at four different locations viz., Bajoga, Gombe, Boderi and Kanawa were identified in determining population of microorganisms in the soil. The samples were collected, numbered and labelled with date and site of collection in an air-tight pre-sterilized polyethene bags before transportation to the laboratory. Serial dilution pour plate technique was used for estimation of total bacterial, fungal, actnomycetes and azotobacter using specific media. The plates were incubated at temperatures specific to particular microbe for 2 -3 days. The colonies that developed on media were counted by electronic colony counter. The microbial counts were expressed as colony forming unit per gram of soil (CFU/g soil). The highest bacterial count (CFU/g) was found in forest land use with the mean value (192.66) and the lowest (41.33) was found in agricultural land use system. The highest total fungal count (CFU/g) was recorded in forest land use with the mean value (77.33) and the lowest (10.33) was found in agricultural land use system. The highest total viable actinomycetes count (CFU/g) was recorded in forest land use with the mean value (62) and the lowest (3) was found in agricultural land use system as compared to other soils in the study area. The perusal of data reveals that for the total azotobacter count (CFU/g), the highest was recorded in forest soils because of the presence of more organic matter with mean value (22.66) as compared with the other land use systems. The lowest was found in agriculture (4.33). Lowest microbial count in agricultural soils may result to poor soil quality and natural productivity which may lead to famine a natural disaster. Planting of cover crops will improve soil structure, enhance soil fertility and sustain or increase soil organic matter and soil biological activity.
