Abstract

Method for direct or indirect release of water to a plant in a culture medium or soil uses a water-insoluble, swellable polymer in the form of a hydrogel. A compact amt. of the polymer material in hydrogen is formed is prepd. according to the requirements of the plant at a specified time under specified conditions of atmospheric temp. and humidity, and introduced into the culture medium or soil in such a position that the polymer material is sepd. from at least a part of the root system. The polymer material is left in place for an intermediate time in order to facilitate gradual transfer of the water contained in the hydrogen into the culture medium or soil and thus to the plant. The rate of release of water to the soil adjusts automatically to plant requirements, and the effectiveness of the hydrogel is prolonged. This is attributed to the fact that the soil or culture medium acts as a buffer which in contact with the hydrogel automatically takes up the amt. of water required to give a moisture content which is optimal for the plant.
