Boost Bean Yields On Heavy Clay: Following a three-year side-by-side comparison of flat plantings and raised-bed plantings on heavy clay soil, MSU-DREC researchers report their findings

摘要

In Mississippi each year, an average of about 1.75 million acres of soybeans are planted. The majority of the crop is planted on clay soils (with poor internal drainage), which are found in naturally low-lying areas. However, many possibilities are available for dodging the negative impacts of the poor drainage. Large scale practices include maintaining obstruction-free drainage ditches and land forming fields to a specific grade. Also, less invasive and smaller-scale measures can be taken. One of the simplest considerations is bedding systems. In addition, growers have available certain varieties with better tolerance to "wet feet" than other varieties, and this information is can be obtained through the Extension service.
