AI Technical Summary
Technical Problem
Urea-containing liquid fertilizers face issues with needle crystal growth during storage, leading to nozzle clogging during mechanical fertilization due to varying solubility with temperature changes.
Method used
Incorporation of a water-soluble organic compound with a linear structure containing hydroxyl, carbonyl, and amide groups, such as polyethers or polyvinyl alcohols, to suppress urea needle crystal growth by adding 0.01-100% by weight of compounds like polyethylene glycol or polyvinyl alcohol.
Benefits of technology
Stabilizes urea in liquid form, preventing needle-shaped crystal growth and nozzle clogging, allowing stable long-term storage and efficient application.

Abstract
To provide a liquid fertilizer, in a urea-containing liquid fertilizer, where growth of a urea acicular crystal is inhibited, a manufacturing method thereof, and a method for inhibiting the growth of the urea acicular crystal.SOLUTION: A urea-containing liquid fertilizer contains urea, a compound A, and water, where the compound A is an organic compound that has a straight-chain structure of 6C or greater, has one or more functional groups among one or more kinds selected from the group consisting of a hydroxy group, a carbonyl group, an amino group, and an amide group, and has solubility where 0.01 g or more thereof dissolves in 100 g of water under 1 atmospheric pressure at 20°C.SELECTED DRAWING: None
