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.

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.

The experiments were conducted in a three-replicate split-plot design of 2 × 4 treatments, with variety as the main plot and nitrogen fertilizer application as the sub-plot. This study was, therefore, conducted to evaluate the effect of nitrogen fertilizer on two okra varieties grown under Thua Thien Hue weather conditions.

The spread of organic farming has led to the need for identifying alternative sources of high-quality organic fertilizer. Azolla is a genus of floating aquatic ferns which has high nitrogen and organic matter content due to its fast growth and symbiotic relationship with nitrogen-fixing bacteria (Anabaena-azollae).

Nitrogen is the most important nutrient for plants, most used in agricultural production. Among nitrogen fertilizers, urea is the most used to provide nitrogen for plants. Due to the effects of climate change, leaching, erosion and improper use have reduced the effectiveness of fertilizers when applied, causing environmental pollution.

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.
