Historically, the agronomic focus of crop mineral nutrition has yielded responses to
individual elements (N, P, K…) to determine the economically optimum fertilization rates …

Responses of individual leaves to short-term changes in CO 2 partial pressure have been
relatively well studied. Whole-plant and plant community responses to elevated CO 2 are …

This new edition of a bestseller examines plant nutrition's role as one of the most important
limiting factors that must be overcome to optimize food production. Extensively revised and …

In the last 40 years, the global use of mineral N fertilizers has increased to support
increasing food demand. Misuse of fertilizer has led to environmental problems in some …

Leaf area growth and nitrogen concentration per unit leaf area, Na (gm− 2N) are two options
plants can use to adapt to nitrogen limitation. Previous work indicated that potato (Solanum …

The effects of nitrogen availability on growth and photosynthesis were followed in plants of
sunflower (Helianthus annuus L., var. CATISSOL-01) grown in the greenhouse under …

Sunflower (Helianthus annuus L.) is considered well adapted to drought, although
systematic analyses of the physiological basis of it, and/or purposeful attempts to breed for …

Abstract Effects of leaf age, nitrogen nutrition and photon flux density (PFD) on the
distribution of nitrogen among leaves were investigated in a vine, Ipomoea tricolor Cav …

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 …

Maintaining current high yields of corn (Zea mays L.) grown in the USA poses an
environmental threat due to continued overuse of water and N inputs. To reduce …
