A plough or plow (both pronounced / p l aʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting. [1] Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil.
The purpose of deep plowing is to modify the soil water retention characteristics over the long term. [1] In one long-term test, lasting 35 years, the mean annual grain yield was 2,800 lbs per acre (3,138 kg per ha) with deep plowing, which was 10% greater than the 2,550 lbs per acre (2,858 kg per ha) yield in unplowed plots.

Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
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 ...
In comparison to no-till, which relies on the previous year's plant residue to protect the soil and aids in postponement of the warming of the soil and crop growth in Northern climates, zone tillage produces a strip approximately five inches wide that simultaneously breaks up plow pans, assists in warming the soil and helps to prepare a seedbed ...
Rather than cutting and turning the soil to produce ridged furrows, the ard breaks up a narrow strip of soil and cuts a shallow furrow (or drill), leaving intervening strips undisturbed. The ard is not suited for clearing new land, so grass and undergrowth are usually removed with hoes or mattocks. Cross-ploughing is often necessary to break ...

Homi (Korean: 호미), also known as a Korean hand plow, [1] [2] is a short-handled traditional farming tool used by Koreans. [3] [4] [5] It is a farming tool that removes grasses from paddies and fields. [6] It is also used when plowing a rice field, planting seeds, plowing up soil, and digging potatoes in fields.
