Abstract
An object of this invention is to obtain a calcium agent for plants, which enters into cells of a plant so as to derive the physiological activity basically for DNA and RNA activation and to enhance the absorbability of calcium into the living plant. Therefore, the calcium agent for plants, contains, as main components, water-soluble low molecular weight chitosan having an average molecular weight of 500 to 30000 consisting of chitosan and/or chito-oligosaccharide and/or derivatives thereof, an inorganic substance including calcium element and/or a water-soluble organic substance including calcium element, and if necessary, water-soluble organic acid. By administering this calcium agent, lime deficiency diseases of plants can be prevented.
