Define the advatages of Potassium

The gross impact of these effects on crop production is manifested  in several ways. Perhaps the first visible indication of a potassium deficiency is the development of leaf characteristics. Potassium is a mobile element which is translocated to the younger  meristematic tissues  if a shortage occurs. As a result, the defic iency symptoms usually appear first on the lower leaves of plants, progressing towards the top as the severity of deficiency increases. In addition potassium shortage is frequently accompanied by a weakening of the straw grain crop particularly rice and wheat which results in lodging of small grains.  Potassium deficiency greatly reduces \crop yields, and decreases resistance to plant diseases. The quality of some crops, particularly fruits and vegetables, is decreased with low supplies of potassium.
