ABSTRACT:
A nitrification inhibitor and a soil improver and a fertilizer containing the same are offered which can be utilized in a wide area from a tropical to a temperate zone, and can be easily obtained from natural origin materials. It is a nitrification inhibitor to inhibit soil nitrification, containing as a main component either one of linoleic acid, α-linolenic acid, γ-linolenic acid, and methyl linoleate, or their mixture of two or more.
