Harrows differ from cultivators in that they disturb the whole surface of the soil, while a cultivator instead disturbs only narrow tracks between the crop rows to kill weeds. There are four general types of harrows: disc harrows, tine harrows (including spring-tooth harrows, drag harrows, and spike harrows), chain harrows, and chain-disk harrows.
It can make a difference. A disk-trenching experiment in the Sub-boreal Spruce Zone in interior British Columbia investigated the effect on growth of young outplants (lodgepole pine) in 13 microsite planting positions: berm, hinge, and trench in each of north, south, east, and west aspects, as well as in untreated locations between the furrows ...

The broadfork is a manual tool specifically designed for this task; a digging fork or a spade might also be used. The chisel plow does a similar job with the help of a tractor.
Municipalities across the United States have adopted similar snow plow trackers. Arlington County in Virginia began its naming contest this year to spread the word about its snow and ice map.
They assessed methodological quality based on components like between-group comparison, blinding, and adequate follow-up. Seven studies were of moderate quality, and four were of high quality.
