Liquid Fertilizer K special technology. Its special composition contributes to the effective and rapid absorption by the roots or leaves of plants and to the good mobility of potassium in plants, even in conditions of salinity stress. Thanks to its high content of organic acids and the form of potassium carboxylic acid, it favors the good absorption of water and nutrients from the root and their distribution to all organs of the plant. The organic acids contained in BIONA ULTRA K participate in the Krebs cycle for the formation of ATP and have a high ability to chelate trace elements found in soil or irrigation water, favoring their absorption by plants. It is especially important to administer it from the fruit set and during the growth of the fruits until the beginning of their ripening, as well as in view of the risk of water stress.
