Redox cycling of sulfur via microbes in soil boosts the bioavailability of nutrients to Brassica napus.

Deficiency of sulfur (S) has been recognized for both dry and wetland plants as a significant growth limiting factor. S-oxidizers enhance the oxidation rate of S and increase sulfate (SO4 - 2) production by making them available in critical growth stages, resulting in higher plant growth and yield. A two-phase study was undertaken to assess the effectiveness of microbial redox reactions on soil nutrient bioavailability and crop growth.

Utilization of organic-residues as potting media: Physico-chemical characteristics and their influence on vegetable production.

Soilless agriculture is acknowledged worldwide because it uses organic leftovers as a means of supporting intensive and efficient plant production. However, the quality of potting media deteriorates because of lower nutrient content and excessive shrinkage of most organic materials. A current study was undertaken to identify the optimal blend of locally available organic materials with desirable qualities for use as potting media.

Exopolysaccharide-producing bacterial cultures of and in soil augment water retention and maize growth.

Land productivity in arid and hot climate regions is constrained by water scarcity due to low rainfall and organic matter, which limit both soil-water retention and crop yields. Main objective of this research was to explore the potential of exopolysaccharide (EPS) producing bacteria screened from different soils for enhancing soil-water retention, phosphorus solubilization and maize growth. Twelve soil samples were drawn from diverse ecologies (sub-humid and arid) to isolate EPS-producing bacteria (EPB), and cultured on LB and Pikovskaya media.

Variations in soil phosphorus fractionations in different water-stable aggregates under litter and inorganic fertilizer treatment in Korean pine plantation and its natural forest.

Soil aggregation in forest ecosystem is considered as a significant physical process mainly influenced by manure, fertilizers or combination. This aggregation may directly alter the soil nutrient and their fractions in soil. So, soil samples were collected from two types of forests i.

Performance and microbial community dynamics in anaerobic continuously stirred tank reactor and sequencing batch reactor (CSTR-SBR) coupled with magnesium-ammonium-phosphate (MAP)-precipitation for treating swine wastewater.

The impacts of magnesium-ammonium-phosphate (MAP) precipitation on the performance and microbial dynamics in an anaerobic continuously stirred tank reactor (CSTR) coupled with sequencing batch reactor (SBR) for swine wastewater treatment were investigated. In CSTR-SBR systems, an overall higher removal efficiency for COD, NH and POas 98.6%, 98.
