The Costs of Erosion: Topsoil’s Role in Food Security
The thin layer of topsoil covering our earth sustains almost all of the life we know. Learn some answers to common questions about protecting it from erosion.
SDSU Research Shows Effects Of Volunteer Corn In Corn And Soybeans
In 2007, researchers at South Dakota State University indicated that volunteer corn is much less competitive in corn than soybean. The South Dakota study (Alms et al. 2007) evaluated the full season effect of a range of volunteer corn densities (800-14,000 plants/acre) on both corn and soybean and reported yield losses that ranged from 0% to 13% in corn and 0% to 54% in soybean.
Soybean Investigations: Research on Your Farm Seeks Farmer Cooperators
SDSU Extension and the South Dakota Soybean Research and Promotion Council are seeking South Dakota Soybean Growers willing to participate in a farmer-led on-farm strip trial research program.
Crop Hour
SDSU Extension will deliver a series of virtual Crop Hour webinars starting January 9 through March 7, 2024, every Tuesday, Wednesday and Thursday from 10:00 a.m.-11:00 a.m. CST.
Late-Season Nitrogen For Soybean?
Some South Dakota soybean fields that were planted early and have had sufficient moisture have reached early pod setting stage (R3) and are looking good.
Consider SCN Sampling This Spring
Soybean cyst nematode management starts with a soil test to determine the presence or absence of this nematode in the soil.
Woody Weeds: Tatarian Honeysuckle
Tatarian honeysuckle (Lonicera tatarica) was brought to North America from Asia in the mid-18th century for ornamental uses. In South Dakota it was also used as a windbreak species until the 1980s.
Multiple Rounds of Severe Weather Bring Heavy Rainfall, High Winds, and Soil Erosion
A combination of tillage, no residue, and lack of crop canopy can lead to severe erosion and topsoil loss in the face of extreme weather patterns in the spring. The most effective strategy for producers to adapt to these extreme events is to improve soil health.
Integrating Perennial Crops in Annual Crop Rotations
The Dakota Lakes Research Farm is working to develop cropping systems that include perennial crops, such as switchgrass, big bluestem and alfalfa, to improve long-term soil health and farm productivity.
Check Fields for Palmer Amaranth
Palmer amaranth, is an aggressive weed from the pigweed family, which has been reported with increasing frequency in recent years around Central South Dakota.
