  1. 100% Soybean Rust Identification and Management [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Soybean rust is a serious threat to soybean production in many parts of the world. If uncontrolled, the disease can cause yield losses approaching 80 percent in some parts of the world including Asia, Africa, and South America. Soybean rust was first reported in the continental United States on November 10, 2004, and was subsequently found in a total of nine southern states. If soybean rust does become established in southern states or in the Caribbean islands, the disease is likely to spread into northern and northeastern soybean-producing states each year."

    "Ryegrasses are the most widely grown cool-season grasses in the world. They have numerous desirable agronomic qualities. They establish rapidly, have a long growing season, are high yielding under favorable environments when supplied with adequate nutrients, possess high nutrient contents, and can be grazed and used for hay or silage. Ryegrasses grow best on fertile, well-drained soils but can be grown on soils where it is too wet at certain times of the year for satisfactory growth of other grasses."

    Source: Department of Crop and Soil Sciences Publications

    "Nutrient management has taken on new meaning in recent times. Soil fertility traditionally dealt with supplying and managing nutrients to meet crop production requirements. The predictable response of a crop to the application of a deficient nutrient has been the focus. Ways of farming to optimize agronomic production and economic returns to crop production were developed to take advantage of these expected crop responses. Changes in the supply of plant nutrients for this purpose have been dramatic since the end of World War II."
