[Problem] The present invention is a liquid fertilizer composition containing three types of diluted nutrients, fertilizer guaranteeing components and trace metal elements, and changes over time, or is crystallized under UV exposure, low temperature storage or high temperature storage. An object of the present invention is to provide a novel liquid fertilizer composition in which precipitation is suppressed. SOLUTION Nitrate nitrogen, ammonia nitrogen and urea nitrogen are 7.5% by mass or more in terms of the total nitrogen, phosphorous is 7.5% by mass or more as P 2 O 5 , and potassium is 4 as K 2 O. .5% by mass or more and containing at least one fertilizer assurance component selected from magnesium, manganese and boron, and at least one trace metal element selected from calcium, iron, copper, zinc and molybdenum A stable high-concentration liquid fertilizer composition characterized by that.
