  • Publication number: 20180339948
    Abstract: Disclosed are a microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt and a method of preparing the same, which relate to the technical field of production of water-soluble fertilizers. The microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The microgranular water-soluble fertilizer product co-produced from potassium nitrate by tower melt has balanced and stable nutrients. The product is microgranular, has a smooth appearance, is less susceptible to agglomeration, is easy to be absorbed and utilized by crops, and contains a full range of nutrients. In addition, the product is produced by a process employing fully automatic dispensing equipment, which mainly integrates “dispensing, mixing and packaging” and is fully automated.

  • Patent number: 9563781
    Abstract: Embodiments of the present invention provide a method, system and computer program product for directional optimization of policy statements for a Web service. In an embodiment of the invention, a method for directional optimization of policy statements in a policy document can be provided. The method can include loading a policy document referenced for a Web service, extracting a policy from the policy document, and determining whether the extracted policy is bi-directional or direction agnostic. A single run time presentation for the extracted policy can be created when the extracted policy is direction agnostic. Otherwise, separate run time presentations can be created for each direction of the extracted policy when the extracted policy is bi-directional.
