PROBLEM TO BE SOLVED: To realize excellent execution of pour manuring in a simple manner where a cut opening part is formed along with a guide for cutting out the opening part even not only in a case where fertilizer having an excellent solubility is utilized, but also a case where ordinary solid fertilizer is utilized.SOLUTION: A fertilizer bag for pour manuring of the invention comprises: a filled up part which is filled up with solid fertilizer; a sealing part closing the filled up part; and a guide for a cut opening part defining a position at which the cut opening part should be formed on the filled up part upon carrying out pour manuring. Upon carrying out pour manuring, the cut opening part is formed along with the guide for the cut opening part on the fertilizer bag.

PROBLEM TO BE SOLVED: To provide a method for producing easily mesoporous alumina.SOLUTION: The method for producing mesoporous alumina includes a step for preparing slurry formed by mixing a water-soluble aluminum salt aqueous solution with an ammonium carbonate aqueous solution, a step for aging the slurry, a step for washing particles obtained by filtration of the slurry, and a step for calcining the particles. In the obtained mesoporous alumina, a nitrogen adsorption isotherm belongs to IV type of IUPAC, and the nitrogen adsorption isotherm has a hysteresis curve in the range of 0.3-0.96 of a relative pressure P/PO, and the peak value of a pore size distribution exists in the range of ≥2 nm to ≤30 nm. When preparing slurry by adding one aqueous solution to the other aqueous solution, aging of the slurry is performed in the range of room temperature or more to ≤120°C, and when preparing slurry by adding two aqueous solutions simultaneously, aging of the slurry is performed in the range of ≥40°C to ≤120°C.

PROBLEM TO BE SOLVED: To provide a method for producing granular potassium chloride capable of being suitably used as a fertilizer by a simple process.SOLUTION: The method for producing granular potassium chloride is provided in which coarsely crushed grains of potassium chloride are used as granulation nuclei, and powdery potassium chloride is stuck to the granulation nuclei with a binder, thereby round granular potassium chloride is produced. It is preferable that the ratio of the binder is 3-50 pts.mass (in terms of anhydride) to 100 pts.mass of the powdery potassium chloride. Further, the ratio of the powdery potassium chloride is preferably 5-80 pts.mass to 100 pts.mass of the coarsely crushed grains of potassium chloride. As the binder, mineral acid iron is suitable.

PROBLEM TO BE SOLVED: To provide a method for producing an inexpensive lime granular material with high hardness and useful especially as fertilizer by mixing lime cake largely occurring at a sugar factory with poultry manure incineration ash, and granulating the mixture.SOLUTION: This method for producing lime granular materials comprises mixing lime cake with poultry manure incineration ash in a mass ratio in terms of solid content of 99:1 to 50:50, granulating the mixture by a vacuum granulator and drying the granules. The lime granular material obtained by the production method may be further crushed.
Abstract:
PROBLEM TO BE SOLVED: To prevent a fertilizer for submerged aquatic vegetation used for recover from lack of nutrient salt of submerged aquatic vegetation due to reduction in nitrogen, phosphor or the like in water from being cemented in a fertilizer container.SOLUTION: The fertilizer for submerged aquatic vegetation contains a component which generates gas by contact with water. As the component generating the gas, a one composed of a foaming agent and a water-soluble solid acid can be preferably used. Concrete examples of the foaming agent includes one or more of alkali metal carbonate, alkali metal hydrogen carbonate, ammonium carbonate and ammonium hydrogen carbonate. Concrete examples of the water-soluble solid acid include an organic acid.
