Computerized fertilizer injector system.

摘要

A computer controlled system for delivering of a fertilizing water stream to crop beds and varying the nutrient content of the water stream to customize it for each crop bed. The nutrient food system utilizes injection pumps (4) with pre-set dose volumes and a computer control (30) which permits the pumps to be stroked at different frequencies based on the flow of a water stream to accurately control the nutrients injected and to permit accurate switching from injecting nutrients of one pre-set menu to those of another pre-set menu.
