The ALMACO Chalk Box Alley marking system is designed to give the researcher a reference mark in the field while planting. The researcher can place a wooden stake at the reference mark with plot information if desired. Can be installed on all planters and is most commonly used in conjunction with Skytrip GPS tripping. System activates when the planter trips by depositing a dollop of chalk. Fully adjustable up, down, fore, and aft to get the exact placement you require and cut down on drift on windy days. Uses standard goal-line or similar chalk.
