In this review we summarize factors determining the plant availability of soil potassium (K),
the role of K in crop yield formation and product quality, and the dependence of crop stress …

Nitrogen (N) is one of the most required mineral elements for plant growth, and potassium
(K) plays a vital role in nitrogen metabolism, both elements being widely applied as …

Nitrogen (N) and carbon (C) are essential elements for plant growth and crop yield. Thus,
improved N and C utilisation contributes to agricultural productivity and reduces the need for …

Ammonium sensitivity of plants is a worldwide problem, constraining crop production.
Prolonged application of ammonium as the sole nitrogen source may result in physiological …

Water and nitrogen availability limit crop productivity globally more than most other
environmental factors. Plant availability of macronutrients such as nitrate is, to a large extent …

Potassium is an essential macronutrient that has been partly overshadowed in root science
by nitrogen and phosphorus. The current boom in potassium-related studies coincides with …

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 …

Ammonia (ammonium ion under physiological conditions) is one of the key nitrogen sources
in cellular amino acid biosynthesis. It is continuously produced in living organisms by a …

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 …
