The basic aim of this study was to compare the denitrification efficacy of 2,5-dichloroaniline, Ammonium Thiosulphate and their combination (1:1) with previous studies. Ammonium Thiosulphate was not used as a nitrification inhibitor in previous research. Our findings depict that there was significant variation among the chemicals, soil and levels in denitrification for early seedling growth of wheat.

Ebook "Nutrient use efficiency in plants: Concepts and approaches" presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment.

Rhizobia topic has been re-focused in recent years because of new findings on their traits not only as nitrogen-fixing bacteria but also as plant growth-promoting rhizobacteria. When combing rhizobial strains with novel biological carriers (e.g., biochar) for inoculant production, it brings great potential for improving soil health in long-term.

In ebook "Ecology of cyanobacteria II: Their diversity in space and time" cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions.

Nitrogen (N) and phosphorus (P) are essential nutrients for plant growth and development. However, too much N and P can be toxic to plants and hurt crops and animals. Analysis and assessment of N and P content in soil and crops will help build a balanced and effective fertilizer plan for agricultural production. This study introduces a new method to determine both TP and TN in one process, reducing the analytical cost and time.

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.
