  2. Contour plowing - Wikipedia

    en.wikipedia.org/wiki/Contour_plowing

    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.

  3. Tillage - Wikipedia

    en.wikipedia.org/wiki/Tillage

    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 ...

  4. Deep plowing - Wikipedia

    en.wikipedia.org/wiki/Deep_plowing

    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.

  5. Plough - Wikipedia

    en.wikipedia.org/wiki/Plough

    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.

  6. Hardpan - Wikipedia

    en.wikipedia.org/wiki/Hardpan

    In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse ...

  7. Tillage erosion - Wikipedia

    en.wikipedia.org/wiki/Tillage_Erosion

    Eroded hilltops due to tillage erosion. Tillage erosion is a form of soil erosion occurring in cultivated fields due to the movement of soil by tillage. [1] [2] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [3] [4] [5] A signature ...

  8. Steam tractor - Wikipedia

    en.wikipedia.org/wiki/Steam_tractor

    Some of the largest steam tractors, such as the 150 horsepower (110 kW) Case (known as "Road Locomotives"), were capable of pulling 30 or more plow bottoms, while most were powerful enough to pull between 6 and 20. Differing soil conditions highly affected the plowing abilities of these tractors.

  9. Stone picker - Wikipedia

    en.wikipedia.org/wiki/Stone_Picker

    A stone picker (or rock picker) is an implement to sieve through the top layer of soil to separate and collect rocks and soil debris from good topsoil. It is usually tractor -pulled. [ 1 ] A stone picker is similar in function to a rock windrower (rock rake); a stone picker generally digs to greater depths to remove stones and rocks.
