  2. Soybean management practices - Wikipedia

    en.wikipedia.org/wiki/Soybean_management_practices

    Closer row widths increase plant to plant competition for nutrients and water but also increase sunlight use efficiency. According to former Iowa State University Soybean Extension Specialist Palle Pedersen, current recommendations are to plant rows that are less than 30" apart. This increases light interception and decreases weed competition. [2]

  3. Soil management - Wikipedia

    en.wikipedia.org/wiki/Soil_management

    Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...

    In 1996, Asgrow released the first Roundup Ready Soybean to the market building upon Monsanto's work to create petunia plants tolerant to small amounts of Roundup developed by Robert Fraley in 1985. The first season of sales saw over 1 million acres using the new seed and quickly over 80% of US soybeans were produced with the seed. [6]

  5. No-till farming - Wikipedia

    en.wikipedia.org/wiki/No-till_farming

    No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain.

    The final characteristics of a soybean plant are variable, with factors such as genetics, soil quality, and climate affecting its form; however, fully mature soybean plants are generally between 50 and 125 cm (20 and 50 in) in height [9] and have rooting depths between 75 and 150 cm (30 and 60 in).

  7. Sowing - Wikipedia

    en.wikipedia.org/wiki/Sowing

    Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals.

  8. Monocropping - Wikipedia

    en.wikipedia.org/wiki/Monocropping

    Monocropping is also referred to as continuous cropping, as in "continuous corn." Monocropping allows for farmers to have consistent crops throughout their entire farm. They can plant only the most profitable crop, use the same seed, pest control, machinery, and growing method on their entire farm, which may increase overall farm profitability.

  9. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Plants hold soil against erosion, and accumulated plant material build soil humus levels. Plant root exudation supports microbial activity. Animals serve to decompose plant materials and mix soil through bioturbation. [70] Soil is the most speciose (species-rich) ecosystem on Earth, but the vast majority of organisms in soil are microbes, a ...
