Tillage, or '''cultivation''' (a term which also has broader meanings related to the raising of Plant s in general) is the agricultural preparation of the Soil by digging it up. Tillage can also mean the land that is tilled. ''Primary tillage'' loosens the soil and mixes in , Disk Plough , Harrow , Dibble , Hoe , Shovel , Rotary Tiller s, Subsoiler , ridge or bed forming tillers, Roller . Weed plants (seeds, tubers, etc.) may be exhausted by repeated tilling. The weeds expend energy to reach the surface, and then get turned into the soil by tilling. The cycle is repeated until the weeds are dead. Modern Agricultural Science has greatly reduced the use of tillage. Crops can be grown for several years without any tillage through the use of Herbicide s to control weeds, Genetically Modified Crops that tolerate packed soil, and equipment that can plant seeds or fumigate the soil without really digging it up. This practice, called No-till Farming , reduces costs and environmental change by reducing Soil Erosion and Diesel Fuel usage (although it does require the use of Pesticides ). Organic Farming tends to require extensive tilling, as did most farming throughout history. Tilling was first performed via human labor, sometimes involving Slaves . Hoofed animals could also be used to till soil via trampling. The wooden Plough was then invented. It could be pulled by Mule , Ox , Elephant , Water Buffalo , or similar sturdy animal. Horses are generally unsuitable, though breeds such as the Clydesdale could work. The Steel plough allowed farming in the American Midwest , where tough Prairie grasses and rocks caused trouble. Soon after 1900, the Farm Tractor was introduced, which eventually made modern large-scale Agriculture possible. REFERENCES |
