Yellow Soybeans
Yellow soybean areas within fields are being noticed in some areas of the state. There are six factors which could be causing the soybean plant yellowing: nitrogen (N), potassium (K), or sulfur (S) deficiency, iron deficiency chlorosis (IDC), soybean cyst nematode (SCN), or yellow flash from Roundup application.
Water Use by Plant Stage
Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.
Plant Nutrient Analysis: Do your soybeans have the right stuff?
There has been a renewed interest in taking samples of soybean leaves for nutrient analysis as a quality control tool to ensure soil and the fertilizer programs are meeting the needs of the plant to eliminate nutrients as a yield limiting factor.
Split Application of Nitrogen in Winter Wheat
Adequate N early in the growing season is important to support healthy tillering and to give young plants the best opportunity to survive the sometimes-harsh South Dakota winter
Soil Testing for Vineyards in South Dakota
Not all soils are conducive to growing quality grapes, so prospective vineyard sites should be tested before a decision is made to plant grapes. Tests can identify soils that are either too high in pH, salts, or salinity, or that are “too rich” (too high in organic matter and nitrogen) for grapes. In addition, testing before planting allows for the incorporation of nutrients—such as phosphorus—that do not move easily through the soil to plant roots.
Cattle and Land Conservation in South Dakota
Analysis of results from a 2017 South Dakota farmer survey reveals that cattlemen tend to be more land conservation oriented than their grain farming counterparts.

South Dakota State University is providing training for food processors who would like to sell food products from their homes following updates to the state’s cottage food laws earlier this year.
June 2019 Climate Outlook for South Dakota
As South Dakota emerges from the wettest 12-month period in 124 years of climate recordkeeping (June 2018-May 2019), June has started warmer and drier than average. The outlook, however, turns towards cooler and wetter than average again for the middle of the month.
Planning for Quality in Wheat
Excess moisture and limited field days have made it difficult for producers to add nitrogen to wheat fields this year. This could be a concern, as nitrogen contributes to both yield and protein. This year, it may pay off to take tissue and soil tests from questionable wheat fields to help with nitrogen application decisions.
