A regular fertilization program is important to maintain healthy, attractive turf and should include applying the correct analysis of fertilizer, using the correct amount, and fertilizing at the proper time. Turfgrasses require a number of nutrients for growth. Three of these—carbon, hydrogen, and oxygen—are rarely lacking because grasses get these elements from carbon dioxide in the atmosphere and water from the soil.
The remaining eighteen essential elements are also obtained from the soil. Nitrogen (N), phosphorus (P), and potassium (K) are needed in the highest concentrations. These major elements are commonly supplemented with fertilizer. The three numbers on the front of fertilizer bags are often called the ”N-P-K” numbers.
In addition to these major nutrients, secondary nutrients and micronutrients are also essential for plant growth. Understanding fertilizer terminology and the different types of nitrogen sources is important when establishing a lawn management plant. Nontraditional or “organic” fertilizers are also an option for homeowners.

While site-specific soil sampling can improve field management, it must be accompanied by the conscientious collection and analysis of data. The new technologies that have elevated precision agriculture into the forefront of farm management cannot offset poor data collection and soil-testing techniques. Inaccurate data on soil properties will inevitably lead to improper management decisions.
This bulletin addresses three primary factors that can affect the precision management of soil fertility: 1) collecting proper soil-sample cores and the consequences of improper soil sampling, 2) breaking the field into smaller management areas, and 3) differences in test results and recommended application rates between soil-test laboratories. A step-by-step procedure is then presented on how to use variabl e yield goals to develop field maps showing variable application rates o f fertilizers and lime.

White clover (Trifolium repens L.) is a cool season perennial legume of Mediterranean origin. White
clover has been used as a forage in North America since Colonial times. Benjamin Franklin noted its
prevalence in cleared and disturbed land as early as 1746. There are many animal and agronomic related reasons for establishing a productive stand of white clover in existing grass pastures. This publication covers tips on selecting, establishing and managing white clover to help ensure a productive stand.|

This research report presents the results of the 2015 statewide performance tests of peanut, cotton, and tobacco. The tests for various evaluations were conducted at several or all of the following locations: Bainbridge, Tifton, Plains and Midville in the Coastal Plain region and Athens in the Piedmont region.
Agronomic information such as grade, fiber data, plant height, lodging, disease occurrence, etc., is listed along with the yield data. Information concerning planting and harvest dates, soil type, and culture and fertilization practices used in each trial is included in footnotes.

This research report presents the results of the 2015 statewide performance tests of soybean, sorghum grain and silage, and summer annual forages. The tests for various evaluations were conducted at several or all of the following locations: Tifton, Plains, and Midville in the Coastal Plain region; Griffin and Athens in the Piedmont region; and Calhoun in the Limestone Valley region.
The University of Georgia soybean variety trials are irrigated. In addition, dryland soybean variety trials were conducted at four locations (Midville, Plains, Tifton, and Griffin), and irrigated, ultra-late planted soybean variety trials were conducted at Midville and Attapulgus. All are included in this report.
Agronomic information, such as plant height, lodging, disease occurrence, etc., is listed along with the yield data. Information concerning planting and harvest dates, soil type, and culture and fertilization practices used in each trial is included in footnotes. Since the average yield for several years gives a better indication of a variety’s potential than one year’s data, multiple-year yield summaries have been included.
