Potassium Comments
POTASSIUM: Characteristics It enhances the ability to resist disease and cold temperatures as far down as 25 deg.F.; potash causes carbon and oxygen to form C02 from which plant sugars are formed; pH of 6 is the lowest advisable. OA78-51 0
POTASSIUM: Deficiencies in Plants Such a thing has never been observed in plants grown either by amateur or professional growers. A67-473 0
POTASSIUM: Excess Problems Scientific tests have Isolated potassium as the potential cause of growth retardation, particularly of flower stem length; a very little is too much and flower production can be reduced substantially. AU84-202 0
POTASSIUM: Function in Fertilizer It builds desease-resistance, improves plant and flower color and production and acts as a stabilizer to growth. A70-139 0
POTASSIUM: Functions It is thought to be related to cell organism, cell permeability and state of hydration;it is possibly vital to the plant's general health. AU75-45 0
POTASSIUM: Properties It is used by plants in relatively large quantity; can become unavailable in some soils; its common reaction is to cling to soil particles in readily available but not readily leachable form; tends to remain in the soil until absorbed by the roots. OD67-219 0
POTASSIUM: Test Feedings It had virtually no effect on the growth of cymbidiums, cattleyas or phalaenopsis at levels of 50ppm., 100 ppm., or 200 ppm. OA79-129 0
