Background A hypothetical ideotype is presented to optimize water and N acquisition by
maize root systems. The overall premise is that soil resource acquisition is optimized by the …

Crop productivity relies heavily on nitrogen (N) fertilization. Production and application of N
fertilizers consume huge amounts of energy, and excess is detrimental to the environment; …

Root exudates play an essential role in helping plants to cope with abiotic stress. However,
the modulation of root exudation profiles under multiple stress conditions is still poorly …

This new edition provides current information on the nutritional requirements of world crops.
It presents research on the acquisition, accumulation, transport, and functions of chemical …

The literature on nitrogen (N) form effects on plants at different stages of their development
has been critically reviewed, assessing the possible mechanisms of these effects. In …

To investigate N metabolism of two contrasting Populus species in acclimation to low N
availability, saplings of slow-growing species (Populus popularis, Pp) and a fast-growing …

Root growth demonstrates a high degree of plasticity in response to spatial variations in the
availability of vital nutrients, and P fertilizer placement depth affects the development and …

Root system architecture has received increased attention in recent years; however,
significant knowledge gaps remain for physiological phenes, or units of phenotype, that …

Returning crop straw, such as biochar, into the field is increasingly recognized as a valid,
environmentally-friendly agricultural strategy to improve soil quality, increase crop yields …

Ectomycorrhizas (EMs), which are symbiotic organs formed between tree roots and certain
fungi, can mediate cadmium (Cd) tolerance of host plants, but the underlying physiological …
