Nitrogen (N) is the main mineral element in plant tissues and almost all of this nutrient is
acquired from the soil by the roots. Nitrogen is available in many different forms in the soil …

In this review, studies in plant nutrition are classified according to their time scales and micro-
or macroscopic level of approach. Short-time scale studies are mostly dealt by plant …

Respiration is a large and important component of the carbon economy of crops. There are
already several good books dealing with the biochemistry and physiol ogy of plant …

Symbiotic nitrogen (N2) fixation in legumes may give the host plant a distinct competitive
advantage; at the same time it is mainly responsible for introducing N into terrestrial …

We present a mechanism of regulation of growth and activity of legume root nodules which
is consistent with published experimental observations. The concentration of reduced …

SoySim is a new soybean (Glycine max, L. Merr) simulation model that combines existing
approaches for the simulation of photosynthesis, biomass accumulation and partitioning with …

Legumes fix atmospheric nitrogen (N) in a symbiotic relationship with bacteria. For this
reason, although legume crops can be low yielding and less profitable when compared with …

Nitrogen derived from symbiotic and mineral sources by a legume is determined by the
interactions between mineral N supply, plant N demand, and N assimilation traits. These …

Associated with Nitrate Reduction A. The Reduction Pathway and Sources of Reductant B …

Fertilization commonly increases biomass production in loblolly pine (Pinus taeda L.).
However, the sequence of short‐term physiological adjustments allowing for the …
