ABSTRACT:
Granular products for the treatment of soil are described which comprises a central solid nucleus containing fertilizer, herbicide, or a mixture of fertilizer and herbicide, all soluble in water without decomposition, as well as, about each product a coating consisting of solid materials at least 40% of which are soluble in water without decomposition, and at least 15% of which consist of active material different from that of the nucleus, and a polymeric resin the amount of which does not exceed 10% of the total weight of the coating. Comparative tests are described which show that these novel granular products can be as readily dissolved in the soil as uncoated fertilizer granules.
