Acknowledge I expresses thanks to Assoc. Prof. rob Reid of Adelaide university of Australia, Dr Jeff Gale, foreign teacher of northwest A&F University of China, and Prof. Zhang Fusuo, Prof. Li Xiaolin of China Agriculture University, Prof Liu Yuanyin of Northeast agriculture Unversity and other authors who provide materials for me, or whose materials, such as photographs and figures etc, I used in the lectures

Plant nitrogen 1.1 Uptake of N 1. N is required by plants in large amounts Most plant material contains 2-4%N and 40%C. 2. N is usually the limiting nutrient in unfertilized systems 3. Most n is taken up from the soil in the form of nht or no a small amount of NH3 can be absorbed through the leaves N2 can be used by legume plant via biological nitrogen fiXation

Plant K A. Potassium content of plants 1.20-50gkg-1 2. Plants take up large amount of K. Only N is taken up more. 3. In some plants (sugar beets and potatoes) K uptake is greater than N uptake

Calcium in physiology Uptake and translocation Higher plants often contain apprecia ble amounts Ca and generally in the order of about 5-30 mg Ca/g dry matter The high Ca2+ concentrations related with the high Ca2+ levels in media not related with the Ca2+ uptake

Concept of organic fertilizers Organic fertilizers-that are derived from the wastes and residues of plants or animals. Such as manure, sewage sludge etc. Some consist of unprocessed plant materials(such as tree leaves, grass clipping, crop residues, and green manure crops)
