The short distance transports of nutrients There are two main steps nutrients translocation in plant after nutrients absorbed by the root. One is the centripetal transport from the rhizoplane through the cortex tissue of the roots towards the xylem vessels of the central cylinder. Another one is the vertical transport from from the root towards the leaves
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
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
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)
