Abstract (en)
[origin: WO0234755A2] The present invention provides methods for altering the concentration or level of nitrate, soluble oxalic acid or oxalate, or nutritional quality indicators in a plant, comprising growing the plant in a hydroponic nutrient medium which contains a nitrogen source, and then alterning the content of the hydroponic medium prior to harvest of the plant so that the medium does not contain a nitrogen source, so that the concentration of oxalic acid or oxalage in the plant is altered.
