This study aims to evaluate the effect of fire on soil properties at Zone A5, Tram Chim National Park, Tam Nong district, Dong Thap province. Findings indicated that soil type was acid sulfate, soil structures were clay, clay-silt and silt-clay. pH was low while moisture was high. Electrical conductivity and bulk density were in the tolerance range for the Eleocharis community.

In this study, the Machine Learning (ML) approach has been adopted using Random Forest (RF) model to estimate the CBR of the soil based on 10 input parameters such as Plasticity Index (PI), Liquid Limit (LL), Silt Clay content (SC), Fine Sand content (FS), Coarse sand content (CS), Optimum Water Content (OWC), Organic content (O), Plastic Limit (PL), Gravel content (G), and Maximum Dry Density (MDD), which can be easily determined in the laboratory.

A retaining wall constructed on expansive soil can be subjected to lateral swelling pressures due to soil swelling, which may cause a significant horizontal deformation and bending of the retaining wall. In Australia, it is generally assumed that the backfill behind a retaining wall is non-expansive material. Therefore lateral swelling pressures induced by expansive soils are ignored in routine design.

This article applies experimental methods in the laboratory to determine the increase of soil density with explosive energy. The results show that soil moisture, explosive mass, and the distance between compacted soil and the explosion centre have influenced the compaction of the studying soil significantly.

Earthworms are present in all types of soil. Changes in land use influence populations of earthworms. However, information on the dynamics of earthworm populations in northern Cameroon is not available. This paper highlights the research carried out on the abundance, biomass, and diversity of earthworm populations throughout four types of land use in northern Cameroon. Earthworms were sampled throughout the rainy season in three regions, across pastures, woody savannahs, grass savannahs, and fields, using formaldehyde and hand sorting.

The results showed that AGC stocks were significantly lower than SOC, normally ranging from 9.9 to 29.55 tons ha-1 . Using the Walkley-Black method, the total SOC was estimated at the range of 81.76 to 323.83 tons ha-1 (with an average of 161.47±15.85 tons ha-1 ), which indicated a strong relationship between tree density and SOC. In addition, using the IDW interpolation method, this study estimated that the total CO2 absorbed by mangrove forests was 1,631,834 tons in Bang La and Dai Hop.

A field investigation was conducted at Instructional farm of Krishi Vigyan Kendra Kendrapara, Odisha during kharif and rabi seasons of 2013-14 and 2014-15 in ricegroundnut cropping system under irrigated medium land situation. The soil of the experimental site was sandy loam in texture with pH of 5.7, organic carbon of 0.52 % having available soil nitrogen, phosphorus and potassium of 390.9 kg/ha, 10.1 kg/ha and 190.1 kg/ha respectively.

The crop is attacked by a number of diseases such as Alternaria leaf blight, Cercospora leaf spot, powdery mildew, downy mildew and anthracnose, amongst which Alternaria leaf blight caused by Alternaria cucumerina is found to cause serious losses throughout Rajasthan and other states. The incidence and severity of Alternaria blight in bottle gourd fields is greatly influenced by temperature, relative humidity, soil condition at the time of planting, splashing rain, wind velocity, leaf wetness and inoculum density available in the soil (Meena et al., 2004).
