Point injection of liquid fertilizer has shown promise as an alternative to standard surface or subsurface fertilizer application, particularly with no‐till and ridge‐till planting systems. Field‐scale point injector applicators are difficult to use in small plots, especially with labeled fertilizer materials such as 15 N. This paper describes the construction and use of a small, inexpensive fertilizer application system, which simulates fertilizer injection by a large point injection applicator. Use of the applicator for 3 yr has shown the unit to be relatively accurate, durable and compatible with a variety of fertilizer materials.
