Ohio Agronomy Guide Bulletin 472 Soil Fertility Elements Essential for Plant Growth Sixteen nutrient elements are essential for the growth and reproduction of plants (see Table 7-1 ). Thirteen of these essential elements, found in inorganic and organic fertilizers, are often divided into three groups. The primary nutrients include the elements nitrogen (N), phosphorus (P) , and potassium (K). The secondary nutrients include sulfur (S), calcium (Ca), and magnesium (Mg). The third group of essential elements are called micronutrients because they are required by the plant in small amounts. These nutrients include iron (Fe), manganese (Mn), boron (B), zinc (Zn), copper (Cu), molybdenum (Mo), and chlorine (Cl). The carbon dioxide in air and water is a source of carbon, hydrogen, and oxygen. There is little control of the availability of these three elements except through drainage, irrigation, and modification of the physical condition of the soil. Most dry plant tissue (94 percent or more) consists of carbon, hydrogen, and oxygen. The other 13 elements (listed above) combined represent less than 6 percent of the plant dry matter. When there is a deficiency of one or more of these 13 elements, plant growth is limited. Table 7-2 shows the primary nutrients removed by crops. The values listed in the table indicate average plant nutrient removal and represent only those nutrients found in the harvested portion of the crops. They are not the quantities of nutrients required to produce the crops at the yield levels indicated. Keep in mind that the mineral content of crops varies widely under different growing conditions, and various mechanisms of fixation and release determine nutrient availability in soils.

About Us The Agronomy and Environmental Management faculty conducts research, through the LSU Agricultural Center , and teaching programs, through the LSU College of Agriculture , in soil chemistry, physics, mineralogy, fertility, microbiology and nutrient cycling, soil genesis and morphology, soil mapping, and global information systems. The diverse plant breeding and genetics group within the department conducts research on soybeans, cotton, corn, sugarcane, forages, wheat, and rice. The department additionally retains scientists working on the physiology and production of cotton, soybeans, and alternative crops. Agronomy and Environmental Management at LSU has forged into exciting new, nontraditional areas in recent years. Environmental concerns have redirected much of the emphasis in both teaching and research. Faculty now have active research programs in wetlands conservation, genetic improvement of plants for environmental reclamation, ground water contamination, waste disposal, composting, best management practices, and pesticide runoff. Agronomy and Environmental Management is a blend of teaching and research in the basic and the applied, the traditional and the nontraditional aspects of agriculture. Students with graduate degrees go on to rich and rewarding careers and a challenge to improve the world in which they live. search Home People Calendar Undergraduate Studies ...

Crop Sciences Doorway to the global food and agriculture system University of Illinois at Urbana-Champaign General Information Welcome to Our Department Course Index ... Return to Report Index Manure Utilization in Crop Production by Glenn Raines, Superintendent, Orr Center Introduction Procedures Findings Table 1 ... Summary Points Introduction: Swine production facilities in Western Illinois consist of basically three types: a) Small operations with individual "pig huts," with animals on pastures or open lots, b) Medium sized confinement operations with a lagoon and/or under-facility manure storage, and, c) Large operations with lagoons and/or above ground manure storage facilities. Effluent accumulation from b and c operations dictates land application and generally at very high effluent rates. Eighteen years ago, the confinement pit manure storage method was used extensively and the continued application of high quality manure had not been thoroughly researched. This study investigates the effects of swine effluent on corn and soybean yields, as well as, the buildup of nutrients within the soil profile. Grain yields and fall soil samples help ascertain the effects of the effluent. Laboratory analyses of the applied effluent help determine nutrient application and potential soil buildup of the essential nutrients. Procedures: A long term swine effluent study (corn and soybean rotation) with effluent rates of 0, 2000, 4000, and 8000 gallons per acre, along with a Conventional Fertilizer (CF) rate is used to monitor the crop's response to injected swine effluent. The Conventional Fertilizer rate is nutrient equivalent to the 8000 gal/A rate of effluent. The effluent is obtained from a swine confinement pit area, agitated for uniform consistency and injected to a depth of nine inches in the spring. The injection slots are positioned on 45 inch centers, creating a pattern where certain rows planted on 30 inch centers will be equidistant from the knife slot and certain rows will be planted directly over the knife slot. Corn or soybeans are planted in 30 inch rows in a timely manner with all other cultural practices performed as needed. Grain yields are recorded.

Index Search Home Alternative Field Crops Manual Introduction This Alternative Field Crops Manual addresses the need for detailed information on the production of a number of agronomic crops adapted to the upper Midwest. Our intent is to provide county extension agents and others in educational roles a concise, uniform source of information on those field crops which may be considered as alternatives to traditional farm commodities. The manual is a joint project between the University of Wisconsin Cooperative Extension Service, the University of Minnesota Extension Service and the Center for Alternative Plant and Animal Products. Extension specialists from both states have written or reviewed each chapter to insure accuracy and applicability of information and recommendations. Inclusion of a crop in this notebook is for educational purposes only; no endorsement of any particular crop is implied. Individual growers should consider the following factors in determining whether a crop might be a viable alternative in their particular situation: Market availability-Amount of demand for the product, market location and transportation to market.

Producers require annual inputs such as seed, fertilizers and herbicides, so they seek assistance in sales or service areas such as crop consulting, chemical application and soil testing each year. Therefore, opportunities for CWS graduates usually have been more stable than for employment areas where inputs can be deferred when income is low. Also, salaries for CWS graduates are at or near the top among all graduates in agriculture. The employment opportunities in CWS can best be summarized by the jobs that our graduates have accepted. Our graduates have been employed as: (1) crop production consultants (agronomist); (2) marketing experts for herbicides, fertilizers and other agricultural chemicals; (3) managers of farm service centers for cooperatives and elevators; (4) agents in the production and marketing of certified seeds; (5) research technicians for private companies and universities; (6) natural resources conservationists and agents for other governmental agencies; (7) county agricultural extension agents; (8) field representatives for sugarbeet or food processing companies; (9) farm managers; (10) farm insurance agents; (11) research associates with private plant breeding companies; and (12) persons involved in the reclamation of strip-mined land.
