Plant scientists have long recognized the need to develop crops that absorb and use
nutrients more efficiently. Two approaches have been used to increase nutrient use …

The rate of N uptake of crops is highly variable during crop development and between years
and sites. However, under ample soil N availability, crop N accumulation is highly related to …

A combination of nitrogen (N) fertilizer side-deep placement and mechanical transplanting of
rice seedling (MSDF) has been recommended as an effective alternative technique to …

From a global viewpoint, a number of challenges need to be met for sustainable rice
production:(i) increasingly severe occurrence of insects and diseases and indiscriminate …

Background Plants can utilize two major forms of inorganic N: NO3−(nitrate) and NH4+
(ammonium). In some cases, the preference of one form over another (denoted as β) can …

The genomic response to low levels of nitrate was studied in Arabidopsis using the
Affymetrix ATH1 chip containing more than 22,500 probe sets. Arabidopsis plants were …

Current global nitrogen fertilizer use has reached approximately one hundred billion kg per
annum. In many agricultural systems, a very substantial portion of this applied nitrogen …

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic
matter influence processes that can control plant growth, microbial infections, and nutrient …

Inorganic nitrogen concentrations in soil solutions vary across several orders of magnitude
among different soils and as a result of seasonal changes. In order to respond to this …

Nitrogen (N) is the most important, essential nutrient for all living organisms on earth; it is
