- Analysis of Soil Tests: Nutrients and Soil Properties to Help Farmers Improve Management PracticesMotley, Natalie M. (Virginia Tech, 2020-05-11)Soil nutrients and properties are the foundation of plant growth and our health. The basis of our soil starts with its texture. Soil texture impacts infiltration rate and cation exchange capacity; which in turn affects water and nutrient availability in plants. Analysis of soil nutrients and properties is imperative for effectively managing adequate soil levels and helping prevent excessive amounts of fertilizer applications. While research studies were conducted to analyze specific nutrients, these studies do not provide farmers the importance of certain nutrients and soil testing on specific farmland parcels. This research study identified soil texture for three parcels of farmland in Dewitt County, Illinois, described soil sampling methodology used, and trends of periodic testing results. Analysis of the soil testing results was compared to recommended optimal soil test values. Key nutrients that were analyzed were phosphorus, potassium, and calcium, as well as pH and organic matter content. Management practices were also assessed. Most test results identified nutrients within the optimum values. Where there were slight variations, effective management of fertilizer applications were applied. Variable rate technology was used to spread fertilizers specifically to field locations in need. Management practices, including crop rotation, were used and based on soil test results, farmers were able to maintain a critical balance of adequate soil nutrients. Further, based on pH soil test results, farmers applied a liming program to regain optimal pH levels for annual crop production. While the organic matter content on one of the three parcels had declined below the Illinois average level, the other two parcels remained within the average range. Maintaining soil nutrient levels through periodic and consistent soil testing is paramount to help farmers more efficiently use limited resources for protecting the soil quality for future generations.
- Corn earworm monitoring in commercial sweet corn fields in Virginia, 2017Kuhar, Thomas P.; Romelczyk, Stephanie; Doughty, Hélène; Few, John; Sutphin, Mark; Deitch, Ursula T.; Love, Kenner; Maxey-Nay, Laura Michele; Cooper, Jason; Pottorff, Steve; Catron, Katlyn; Siegle, Laura (Virginia Cooperative Extension, 2018-03-05)Discusses the monitoring of the corn earworm in sweet corn fields. This pest is the most significant pest impacting sweet corn in Virginia.
- IMPACT: Virginia Potato Disease Advisory ImpactHerbert, D. Ames Jr.; Long, Theresa; Deitch, Ursula T.; Laub, Curtis A.; Rideout, Steven L.; Moore, David M.; Tucker, Lindy; Archibald, Thomas G. (Virginia Cooperative Extension, 2014-11-13)To help potato growers more efficiently manage disease problems, Virginia Cooperative Extension initiated the Virginia Potato Disease Advisory to provide growers with weather-based disease forecast information. Advisories not only alert growers to periods of risk, they also assist growers in making management decisions, such as when protective fungicide applications are needed.
- The Nutrient Value of StrawReiter, Mark S.; Deitch, Ursula T.; Frame, William Hunter, 1985-; Holshouser, David L.; Thomason, Wade E. (Virginia Cooperative Extension, 2015-06-19)Discusses the nutrient potential of straw, which can increase soil carbon, and levels of nitrogen, phosphorus, potassium, and sulfur.
- Proper fertilizer placement through better soil sampling with precision agricultureMason, John E. (Virginia Tech, 2020-09-09)Fertilizer use and proper nutrient management are key components to stay economically competitive in agriculture. Fertilizer that is removed from fields during harvest must be replaced to ensure nutrient availability for crop production. Soil sampling is the best way to determine the amount of nutrients need, but where they are needed depends on the type of sampling. Traditionally samples were collected so that one sample represented 20 acres, sometimes samples are grouped by soil series, A Veris 3100 EC cart (Veris Technologies, Salina, KS; http://www.veristech.com/) was used to map soil texture and sampled on a 100 ft X 100 ft grid to compare the different methods. Results from the study demonstrated significant spatial variability was present between whole field composite sampling, traditional field sampling, zone sampling, and zone 2.5 acre grid sampling.

- Virginia On-Farm Soybean Test Plots, 2015Balderson, T. Keith; Broaddus, Mike; Clarke, Taylor; Deitch, Ursula T.; Flanagan, Roy; Hopkins, Steve; Jones, Bruce; Jones, Trent; Lawrence, Watson; Long, Theresa; Moore, David M.; Norton, Nikki; O'Keefe, Christine; Reiter, Scott; Romelczyk, Stephanie; Siegle, Laura; Slade, Glenn; Tucker, Lindy; Holshouser, David L. (Virginia Cooperative Extension, 2016-01-25)Discusses data collected from soybean test plots in 2015 including variety selection, fungicides, maturity and development of plants, seed treatments, and tillage systems.
- Yellow Corn in Virginia - Spring 2017Deitch, Ursula T.; Frame, William Hunter, 1985-; Reiter, Scott; Reiter, Mark S.; Spencer, Janet; Thomason, Wade E. (Virginia Cooperative Extension, 2017-07-10)Discusses the status of corn plants in spring 2017 in Virginia. Many of the plants were noted as stunted and yellowed. Reasons for this included colder than average spring temperatures, wet soils, lack of sunshine, nutrient deficiencies, soil pH, and perhaps also the types of hybrids planted.
