Soil Conservation Practice Adoption Status at the S.D. County Level: 2012–2017

An increasing number of farmers across the state of South Dakota have adopted different soil conservation practices such as no-till, conservation tillage and cover crops. Over time, these practices play significant roles in improving soil health and increasing soil resilience towards extreme weather conditions.

Large Farms More Dominant in South Dakota Crop Production

Large farms play a more dominant role in South Dakota crop production, according to the recently released 2017 U.S. Census of Agriculture. As of 2017, large farms of more than 2,000 acres operate 66.8% of South Dakota total cropland aces compared to 47.7% as of 1997.

Cover Crop Usage in South Dakota is on the Rise

The number of South Dakota producers who use cover crops has been increasing at an accelerating rate over the past ten years.

Rotational Grazing Benefits: South Dakota Producer Perceptions

To better understand producer perceptions on rotational grazing, we sent out 1,500 surveys to South Dakota ranchers inquiring about adoption status and perceptions of rotational grazing.

Soybean Production: Cost-effective pest management practices

Chemicals were one of the most expensive individual costs in soybean production, behind only to seed in the non-land cost category. The average cash-rent soybean production farms incurred a crop chemical cost of $39/ac in 2015, an 88% increase from 2010.

South Dakota Grazing Management Practices: Current & Future

Grazing land occupies 54% of rural land and accounts for a key portion of land use in South Dakota. Many grassland problems can be avoided by using efficient grazing management practices.

Project to Study Soil Health Economics in South Dakota

Soil degradation has become one of the most pressing global issues, because of its adverse effects on world food security, environment and quality of life.

Factors Affecting Wheat Production Decisions: Producer survey findings

Recent USDA data shows that during the past 3 years acres devoted to wheat production continue declining in both South Dakota and North Dakota (USDA, 2018). South Dakota wheat acres experienced a remarkable decrease of 31.5% during the past 3 years, compared with a relatively mild drop of 16.4% by North Dakota.

Crop Rotation Potential: Improving Soil Health & Farm Profitability

Two-year corn-soybean rotation coupled with heavy chemical inputs has become the routine practice of agricultural production in the Midwestern United States. According to USDA/NASS data, corn and soybean prices received by producers in South Dakota both reached the peak levels of $7.39 and $16.00 per bushel, respectively, in August, 2012.

Cover Crop Adoption: Farmers’ perceived benefits & barriers

Cover crops are generally defined as crops planted between cash crops to cover and protect the soil. Some demonstrated benefits of cover crops include: reduced soil erosion, increased soil organic matter, increased biological variety, increased nitrogen supply, and weed control. Depending on the farmers’ objectives, different species of cover crops can be planted. For example, if a farmer’s main objective is to increase nitrogen supply, then legume cover crops best suited to the farm area should be selected.
