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.

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.
