Mangrove Blue Carbon Stocks
Mangrove forests play an important role in mitigating climate change but are threatened by aquaculture expansion (shrimp ponds). The change of land use from natural environments to productive uses, generates a change in the balance and carbon sequestration and storaging. In mangrove forest the carbon stocks are larger than in other tropical forest. Addtionally, soil mangrove forest represent 40-80% of Cardon stocks.  These reasons are the evidence of mangrove forest need to be included in REED programs and conservation strategies.

Potential and Field Measurements of Soil Carbon Sequestration
Soil carbon sequestration (SCS) is a key priority in the Australian government’s Long-Term Emissions Reduction Plan. Under the government’s Emission Reduction Fund (ERF), farmers are encouraged to change to a management practice that will increase their soil carbon (C) stock and earn Australian Carbon Credit Units (ACCUs).

Chemical Analysis of Organochlorine Pesticide in Agricultural Soils
Soil constitutes the central environmental compartment that, primarily due to anthropogenic activities, is the recipient of several contaminants. Among these are organochlorine pesticides (OCPs), which are of major concern, even though they were banned decades ago due to their persistence and the health effects they can elicit. A plethora of methods have been developed and applied for OCP analysis in environmental matrices (i.e., soil and sediment). The entire chemical analysis involves several crucial stages such as sample preparation and analyte chromatographic separation, including detection, quantification, and data analysis. Among them, the sample preparation step is considered as the most critical point to be made prior to instrumental analysis. In particular, the development of methodologies for determining pesticides in soil is a challenging task. As a result of the complexity and the physicochemical characteristics of such types of samples, two main factors should be considered: (a) the extremely low concentration of banned OCPs in soil samples. This is the reason why extremely sensitive analytical methods (including, in many cases, enrichment techniques) are required for the detection and quantification of these analytes at such levels, and (b) the strong binding of OCPs to soil.

Antimicrobial Resistance in Agricultural Soils
Excessive use of antibiotics in the healthcare sector and livestock farming has amplified antimicrobial resistance (AMR) as a major environmental threat in recent years. Abiotic stresses, including soil salinity and water pollutants, can affect AMR in soils, which in turn reduces the yield and quality of agricultural products.

Soil Carbon Sequestration
Carbon sequestration is the process of capturing, securing, and storing carbon dioxide from the atmosphere. Carbon is sequestered in soil by plants through photosynthesis and can be stored as soil organic carbon (SOC). The amount of SOC accumulated in RMS was mostly influenced by the restoration age, vegetation type, and substrate or type of reclamation used.

Optimizing Sustainability Opportunities for Biochar
Biochar is most commonly considered for its use as a soil amendment, where it has gained attention for its potential to improve agricultural production and soil health. Twenty years of near exponential growth in investigation has demonstrated that biochar does not consistently deliver these benefits, due to variables in biochar, soil, climate, and cropping systems. While biochar can provide agronomic improvements in marginal soils, it is less likely to do so in temperate climates and fertile soils. Here, biochar and its coproducts may be better utilized for contaminant remediation or the substitution of nonrenewable or mining-intensive materials.

Agro-Industrial Waste Composting Process Enhancement via Microbial Inoculation
Composting is an important technology used to treat and convert organic waste into value-added products. Recently, several studies have been done to investigate the effects of microbial supplementation on the composting of agro-industrial waste. According to these studies, microbial inoculation is considered to be one of the suitable methods for enhancing the biotransformation of organic materials during the composting process.

Heavy Metals in Agricultural Soils
Population growth and increasing food demand have led to an intensification of agricultural production systems, putting stress on soils and increasing soil contaminants. Some human-induced contaminants, such as heavy metals (HMs), are well-known and have been present in agricultural soils for a long time. In order to provide an overview of HMs in agricultural soils, it is important to investigate agriculturally related sources of contamination with HMs, behaviour of HMs in agricultural soils, as well as their interactions with soil microorganisms, fauna, and plants.

Mechanism of Remediation of Contaminated Soil by Nanoparticles
The varied sources of soil pollution include the application of chemical fertilizers and pesticides, industrial discharge, and transformed products of these accumulated chemical residues. These processes may hamper the composition and soil ecosystem. Different types of methodologies ranging from physical, chemical, and biological approaches have been exploited to tackle this challenge. Nanomaterials (NMs) research has contributed to a new dimension for the remediation of polluted soils.

Seasonal Changes in Soil Microbial Community
Hazelnut is one of the four major nuts in the world and has high nutritional and economic value. This study employed Illumina sequencing of ITS rDNA and 16S rRNA genes to identify the seasonal changes in soil microbial community, the predominant environmental factors driving microbial community composition, and the differences in soil microbial composition among different species of the genus Corylus. We found that the soil microbial community composition of species of Corylus changed significantly with the change in seasons. Corylus heterophylla and Corylus kweichowensis had more ectomycorrhiza in their soil compared to Corylus avellane. The main factor influencing fungal community composition in soil was the available potassium, while that of bacteria was the total phosphorus content.
