An object of the present invention is to provide a liquid fertilizer containing 2,2′-iminodipropanoic acid and / or a salt thereof. The present invention is a liquid fertilizer containing 2,2′-iminodipropanoic acid and / or a salt thereof as a stabilizer. The liquid fertilizer may further contain magnesium phosphite and has a pH of 3.5 or less. Calcium is preferably coordinated to the 2,2′-iminodipropanoic acid and / or salt thereof. The 2,2′-iminodipropanoic acid and / or salt thereof, calcium and magnesium phosphite are dissolved in an aqueous medium, and the liquid fertilizer is clear. The content of the 2,2′-iminodipropanoic acid and / or salt thereof is preferably 0.1% by mass or more and 30% by mass or less. As the 2,2′-iminodipropanoic acid and / or a salt thereof, a by-product generated in the alanine production process may be used. [Selection figure] None |
