The Agronomy Management sequence emphasizes a broad knowledge of agricultural production, science, and agribusiness management. Graduates are employed by companies as crop consultants, for sales and marketing of equipment, and by companies specializing in agronomic products including seed, fertilizer, and pesticides. Additionally, career opportunities are available with local, state, and federal governmental agencies, including such organizations as Soil and Water Conservation Districts, Extension Service, and the Natural Resources Conservation Service.
The Crop and Soil Science sequence emphasizes the scientific aspects of agronomy including improving plant production, quality, and profit by utilizing plant genetics and breeding and improving the soil physical, chemical and microbial characteristics to enhance crop production.
CSA is a set of agricultural practices and technologies which simultaneously boost productivity, enhance resilience and reduce GHG emissions. Although it is built on existing agricultural knowledge, technologies, and sustainability principles, CSA is distinct in several ways. First, it has an explicit focus on addressing climate change in the agrifood system. Second, CSA systematically considers the synergies and tradeoffs that exist between productivity, adaptation, and mitigation. And third, CSA encompasses a range of practices and technologies that are tailored to specific agro-ecological conditions and socio-economic contexts including the adoption of climate-resilient crop varieties, conservation agriculture techniques, agroforestry, precision farming, water management strategies, and improved livestock management. By implementing these practices, triple win results can be achieved:
Plant residue management is another way of controlling soil erosion by intercepting raindrops, thereby reducing surface runoff and protecting soil surface particle detachment by raindrop impact. Crop residue can provide an excellent soil cover after harvest and enhance snow harvesting during the off season, improve soil water intake by preventing soil surface sealing due to raindrop impact, and consequently, reduce surface runoff. Equally important in minimizing soil erosion is the adoption of a cropping system along with conservation tillage practices such as no-till, strip-till, and ridge-till. The degree of effectiveness of different tillage practices depends on the degree of soil manipulation, which effects the residue distribution on the soil surface. Table 1 shows combinations of different cropping systems and the relative scale of erosion hazard associated with each system.
Studies will include the principles of managing land, people, capital, and other resources to create a profitable, sustainable system of food and energy production. The 400-acre Woodroof Farm serves as a primary classroom for students in the Agriculture program. Hands-on experience on campus and through our agribusiness partners in the community provide students with tactical skills applicable on day one in the workforce. Graduates have found success at various businesses that manufacture, produce, market, process, and support agricultural-related products and services.
The Agricultural Technology and Systems Management track is for students to study to advance and preserve the future of farming in our country. Students will learn to combine an understanding of agricultural, biological, and physical sciences with business, managerial, and technical skills to create solutions for more effective crop production and farm management.
Potential career paths include technical positions focusing on the production, processing, and manufacturing of agricultural materials, which may focus on irrigation, equipment design, crop production, and much more.
The BS in Agricultural Technology Management will prepare students for technical careers focused on the sales or management in the production, processing, or manufacturing of agricultural materials. These careers may be related to crop production, extension, precision agriculture, irrigation management, design and testing of equipment, and many other positions related to commercial agriculture. Students will combine an understanding of the agricultural, biological, and physical sciences with business, managerial, and technical skills.
The Grain Systems Certificate (CT) leads graduates into a career in crop management and grain system design. This credential gives students the opportunity to learn about how grain systems affect our food supply, and how to operate and maintain them to help feed our communities.
Experience with formal education requirement: In addition to formal education, applicants must have at least one year of practical experience related to nutrient management planning or the application of nutrient management concepts and principles. This includes working farmers, landowners or grounds maintenance supervisors to develop fertility programs for crop production or for the establishment and maintenance of turf or landscaped areas.
Experience requirement with no formal nutrient management related education: Three years of practical experience related to nutrient management planning are required. This includes working in any capacity directly with farmers, landowners or grounds maintenance supervisors to develop fertility programs to produce crops or establish and maintain turf or landscaped areas. Work experience must include the use of fertilizers, manures and biosolids, or any combination thereof, taking into account soil productivity, realistic yield goals, nutrient needs that meet specific use requirements of given sites, environmentally sensitive areas, and the timing of nutrient applications to determine nutrient recommendations. Such experience would entail dealing directly with people in the following positions, or holding such positions, as:
Description: This session is a lecture series by Virginia Tech professors covering soil science, soil fertility, organic nutrient sources and crop production topics. Students without previous training in these subjects will find this session helpful in understanding how nutrients react and interact when applied to the soil. The session is a mini-agronomy course. It will also help prepare students for the core component of the exam. The registration fee includes copies of all presentations, student exercises and reference materials.
Weather risk in production agriculture is ubiquitous and the successful execution of a crop plan requires accurate weather forecasting and analysis. We plan our operations based on weather averages and our experiences over recent growing seasons, but each year presents a new set of weather challenges. In this talk we will focus on how to use the abundance of weather data to stay ahead to disruptive weather events. We will talk about the limits of predictability for weather events and learn about the resources available to monitor changes in the longer range forecasts. We will review the major lessons from the 2023 growing season and talk about the high impact events like widespread hail damage, Midwest and Southern US Drought, and the hurricane season. We will talk about the big seasonal drivers like El Niño and La Niña discuss the outlook for the next 3-9 months. We will finish with a discussion about the 2023-24 growing season in South America, which competes directly with major US commodity crops.
There is a growing movement in agribusinesses, government, and non-profit organizations recognizing the value of private-public partnerships when it comes to maintaining farm profitability and achieving environmental outcomes. At the same time, Minnesota is awash with unprecedented state and federal funding for conservation practices such as cover crops, reduced till, strip-till, no-till, nutrient management, conservation crop rotations, and more.
Mushroom farming consists of six steps, and although the divisions are somewhat arbitrary, these steps identify what is needed to form a production system. The six steps are Phase I composting, Phase II composting, spawning, casing, pinning, and cropping. These steps are described in their naturally occurring sequence, emphasizing the salient features within each step. Compost provides nutrients needed for mushrooms to grow. Two types of material are generally used for mushroom compost, the most used and least expensive being wheat straw-bedded horse manure. Synthetic compost is usually made from hay and wheat straw, although the term often refers to any mushroom compost where the prime ingredient is not horse manure. Both types of compost require the addition of nitrogen supplements and a conditioning agent, gypsum.
Phase II takes place in one of three places, depending on the type of production system used. For the zoned system of growing, compost is packed into wooden trays, the trays are stacked six to eight high, and are moved into an environmentally controlled Phase II room. Thereafter, the trays are moved to special rooms, each designed to provide the optimum environment for each step of the mushroom growing process. With a bed or shelf system, the compost is placed directly in the beds, which are in the room used for all steps of the crop culture. The most recently introduced system, the bulk system, is one in which the compost is placed in an insulated tunnel with a perforated floor and computer-controlled aeration; this is a room specifically designed for Phase II composting (Fig. 2).
Phase III compost is Phase II compost spawn run in bulk in a tunnel, and ready for casing when removed from the tunnel and delivered to the grower. If the Phase III compost then is cased and the spawn allowed to colonize the casing layer before sending to the growing unit or delivering to growers, it is called Phase IV compost. The successes of both Phase III and Phase IV compost depend, to a large extent, on the quality of Phase I and Phase II composts. Use of Phase III compost may also improve mushroom quality, as fragmentation of the colonized compost tends to improve initial color and mushroom shelf life. In recent years, the use of bulk Phase III compost has increased in popularity because it allows an increase in the number of crops a grower can expect from his production rooms. Phase II production on shelves allows an average of about 4.1 crops per year whereas growers using Phase III bulk spawn run compost averages about 7.1 crops per year. An additional gain can be made in the number of crops (10-12 crops per year) when Phase IV is used (Dewhurst 2002; Lemmers 2003; Chang 2006).
