Abstract. The use of fertilisers in agriculture and horticulture is the key to production of sufficient food (including the fodder for animals) to maintain the global human population (currently 6 billion; Evans 1998) and to permit its continued rapid growth to the expected 10 or even 12 billion (Bumb 1995). Nitrogen in a form which can be used ...

Background and aims Dissolved organic matter (DOM) is a vital bioactive component in soil nutrient cycling. However, the dynamics of its characteristics and composition along the soil profile during desertification reversal are poorly understood. Methods Soil samples were gathered from shrub and arbor forests that have been …

P. brassicae transcriptional patterns were modulated by nitrogen supply, these modulations being dependent on both host-plant genotype and kinetic time. Functional analysis allowed the identification of P. brassicae genes expressed during the secondary phase of infection, which may play a role in the reduction of Yudal disease …

Nitrogen is an essential nutrient required for plant growth. It is a primary constituent of nucleic acids, amino acids and proteins. Although 78% of the atmospheric air is made of N 2, only legumes are able to convert atmospheric N 2 to plant available forms of nitrogen via a symbiotic biological process involving Rhizobium bacteria resident in …

This review summarizes the recent progress in the field of plant nitrate (NO3-) and ammonium (NH4+) uptake, which are the two major forms of N that are absorbed by plants. We explore the intricate relationship between NO3-/NH4+ and abiotic stress …

Nitrogen addition decreased Ca and Mg concentrations, CEC and BS ratio in topsoil but increased available Fe, Mn and Cu concentrations across the entire soil profile. Water addition weakened N addition effects on soil extractable cations, further indicating that the N effects could be enlarged in nature without considering increased ...

Accurate estimates of total leaf area and the vertical leaf area profile are important in process-based crop growth models. The bell-shaped function that quantifies the area-per-leaf profile of a maize (Zea mays L.) plant can be used to estimate the area-per-leaf profile.The objectives of this study were to quantify the effects of maize hybrid, soil …

Nitrogen being a major food for plants is an essential constituent of protein (build from amino acids that involves in catalization of chemical responses and transportation of electrons) and ...

When nitrogen uptake exceeds plant assimilation capacity, plants will accumulate excessive NO − 3 -N and NH + 4 -N, which will lead to soil secondary salinization and plant salt toxicity, thus ...

Soil and Plant Nitrogen. by G. Hofman and O. van Cleemput. First version, published by IFA . Paris, France, September 2004. ... is the mineral N in the soil profile to the mean rooting depth.

nitrogen availability across multiple regions of the plant. Results In order to study the expression profiles of maize nitrogen transporter genes, plants were grown using a semi-hydroponic system in the glasshouse that enabled full-plant growth with the ability to access aerial and root samples. Plants were harvested at a vegetative (V7) and re-

Nitrogen gas was produced using an NM30L nitrogen generator (Peak Scientific, Renfrewshire, Scotland). ... protein blends composed of solely plant-based proteins designed to provide a more balanced essential amino acid profile, and/or individual plant-based proteins with a more optimal amino acid composition. Dietary …

Background: In order to grow, plants rely on soil nutrients which can vary both spatially and temporally depending on the environment, the soil type or the microbial activity. An essential nutrient is nitrogen, which is mainly accessible as nitrate and ammonium. Many studies have investigated transport genes for these ions in …

1. Introduction. Nitrogen has profound effects through plants that can extend across trophic levels. In plant–herbivore interactions, low nitrogen availability decreases plant quality as a food resource for herbivores in many cases, which can be further exacerbated by increases in plant defensive compounds (Stout et al., 1998, Chen et al., …
