Title:
FERTILIZER CONTAINING OYSTER SHELL
Document Type and Number:
Japanese Patent JP3705342
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a fertilizer having excellent granulatability, handling quality and collapsing property by moisture in soil by mixing pulverized oyster shells and pulverized brucite, mixing a lignin compound or waste alcohol fermentation liquid and a water-soluble binder therewith and kneading the mixture.
SOLUTION: The oyster shells are pulverized to ≤2 mm and the brucite pulverized to ≤2 mm, more preferably ≤0.2 mm is mixed therewith. The mixing ratio of the oyster shells and the brucite is preferably in a range of about 90:10 to 45:55, more specifically about 90:10 to 70:30. Further, the water-soluble binder is mixed with this mixture and the mixture is kneaded. The mixture is then granulated to a spherical shape of 1 to 6 mm in diameter. About 2.0 to 6.0 wt.% lignin compound or about 2.0 to 8.0% waste alcohol fermentation liquid is preferably used as the water-soluble binder. As a result, the fertilizer containing the oyster shells which may be granulated to the easy-to-handle and hardly collapsible spherical shapes and are easily collapsible in the soil or the moisture in the soil is obtained.
