This study evaluated the relationship between selected physicochemical properties and microbial populations of the soil of Bagale Forest Reserve, Girei Local Government Area of Adamawa State, Nigeria. Five plots of 20 x 20 m were laid. Soil samples were collected from five different positions at two soil depths of 0-15 cm and 15-30 cm. The soil sam...

... research was carried out at Bagale Forest Reserve in Girei Local Government Area of Adamawa State. The area lies between latitudes 9 o .09 and 9 o .33 N and longitudes 12 o .21 and 12 o .54 E of the state and has an elevation of 339 meters above the sea level (Fig. 1). The study area is located within the North-Central part of Adamawa State. Bagale Forest Reserve covers a total land area of 179.746 km 2 , which is equivalent to about 18 ha [3]. The major vegetation formations in Adamawa State are Southern Guinea Savannah, Northern Guinea Savannah, and Sudan Savannah. In Bagale Forest Reserve, in ...

The effect of soil moisture and tillage depth was studied on some mechanical properties for type tillage machine (moldboard plow) and soil physical characteristics on wheat Zagros variety at two soil moisture levels of 13-15%and 15-17% and three levels tillage depth of 10,12 and 14 cm. The experiments were carried out in a factorial experiment unde...
Soils subjected to disaggregation can break into aggregates of different sizes composed of sand, clay, and silt particles. Each aggregate contains different oxides, which can vary according to the aggregate size and influence its properties, such as the radiation interaction parameters. These parameters are relevant in the evaluation of radiation s...
Soil deterioration and yield decline are the main factors affecting the environmental sustainability of long-term irrigated sugarcane monoculture. This research was conducted to detect changes of soil physical, chemical and physicochemical quality parameters associated with intensive irrigated sugarcane monoculture with groundwater for long term.

An experiment was conducted aiming to understand the interaction of tillage depth and cropping systems on the yield of crops and soil physical properties. The experiment compared nine treatment combinations comprising three tillage depths as zero tillage (ZT), tillage by power tiller up to 10-12 cm depth (PT) and tillage by chiseling up to 20-25 cm...

... The findings of the comparative analysis of the microbial load of both fungi and bacteria were influenced by physical features of the soil. This agrees with finding of (Ateh et al., 2020) who reported that the texture of the soil determine the nature of microbes present. Microbial organism plays importance roles in the decomposition of organic matter, nitrogen fixation and nutrient cycling (Lawal et al., 2018;Ateh et al., 2019). ...
This study was carried out in the year 2021 at Kiyawa community which aimed to investigate growth attributes, identified the fungi, bacteria and determined the microbial load in the neem and eucalyptus shelterbelts. 1 kilometer line transect was laid with four sample plots established (30 × 30m) which were used for collecting data of the tree with an interval of 100m from each plot. Also, 1×1m mini-plots were used for measuring quantity of litters. Diameter at breast height and height were accessed with the aid of meter rule and Haga altimeter while volume and Basal area were calculated. Potato Dextrose Agar (P.D.A) media used for the isolation of fungi while Nutrient Agar (N.A) medium was used to isolate bacteria sterilized in autoclave for 15 minutes at 121°C. Fungi Morphology was studied with aid of microscope by observing colony features. The data collected was analyzed using descriptive statistic (table) and inferential statistic: t-test was employed. The results showed that Azadirachta indica plots had the highest Dbh, Basal area, Height, and volume of 82.25cm±1.23, 0.90m 2 ±0.15, 15.90m±0.24, 970.78 m 3 ±4.27m 3 followed by the Eucalyptus camaldulensis hotspot which had the least value of 62.50cm±0.93, 0.463m 2 ±3.43, 3.75m±0.03 and 347.85±2.43m 3 respectively. The findings showed the presence of three (3) species of bacteria in each study site. Eucalyptus shelterbelt has Staph avenus and Bacillus cereus while Bacillus subilis and E. coli were presence in Neem hotspot. Pseudomonas spp can be traced to both hotspots. Fungi traced to the both study sites were Aspergillus niger and Penicillum species. However, Aspergillus flaming occurred in eucalyptus hotspot while Fusarium oxysporum present in Neem shelterbelt. Result revealed that grand mean microbial load of fungi (Eucalyptus 1.45x 10 6 ; Neem1.50x10 6) is higher than bacteria (Eucalyptus 1.24 x 10 6 ; Neem1.3 x10 6). There is significant difference between the bacterial microbial loads between the study sites at (p≤ 0.05). The hotspots support better growth attributes of neem tree and fungi microbial load. Therefore, neem tree is recommended for economic and ecological reasons and adaptive arable crops should also intercrop with tree to supply improve economic value of shelterbelt and land user.
