Soybean management practices
Soybean management practices in farming are the decisions a producer must make in order to raise a soybean crop. The type of tillage, plant population, row spacing, and planting date are four major management decisions that soybean farmers must consider. How individual producers choose to handle each management application depends on their own farming circumstances.
==Tillage==
Tillage is defined in farming as the disturbance of soil in preparation for a crop. Tillage is usually done to warm the seed bed up, to help dry the seed bed out, to break up disease, and to reduce early weed pressure. Tillage prior to planting adds cost per acre farmed and has not been shown to increase soybean yields significantly.
“No till” is the practice of planting seed directly into the ground without disturbing the soil prior to planting. This practice eliminates the tillage pass, saving the farmer the associated costs. Planting no-till places seed directly into a cooler and wetter seed bed, which can slow germination.〔Robert G. Hoeft, Emerson D. Nafziger, Richard R. Johnson, and Samuel R. Aldrich . Modern Corn and Soybean Production. '1st ed. Champaign, IL: MCSP Publications, 2000.〕 This process is considered a good conservation practice because tilling disturbs the soil crust, causing erosion. The practice of no-till is currently on the rise among farmers in the midwestern United States.
