Much attention has been placed on the potential negative environmental impacts of grazing; however, grazing can be a powerful tool for improving pasture health and productivity. Grazing diminishes the competitive ability of plants like broomsedge and johnsongrass and improves the competitiveness of bermudagrass, bahiagrass and even clovers. Improper grazing, on the other hand, can decrease the competitiveness of desirable species like orchardgrass or switchgrass and encourage undesirable weedy species.

2016 Georgia Corn Performance Tests
In this research report, the results of the 2016 corn performance trials are presented. Short-season and mid-season hybrids were planted at Tifton, Plains, and Midville in the Coastal Plain region, at Griffin in the Piedmont region, at Calhoun in the Limestone Valley region, and at Blairsville in the Mountain region. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun, and Blairsville.

This is a biennial publication containing the proceedings of the turfgrass research field day carried out at the UGA Griffin Campus every other year. The guide provides professionals with continuous, real time access to the latest up-to-date information about turfgrass research studies, products, and turfgrass Extension activities, programs, and outreach.
Topics will include, but are not limited to, crop and soil science, agronomy, weed science, plant pathology, entomology, economics, tissue culture, urban agriculture, irrigation, and student posters.

This research report includes the results of the 2015-2016 performance tests of small grains grown for grain and forage. Grain evaluation studies were conducted at five locations in Georgia, including Tifton, Plains, and Midville in the Coastal Plain region; Griffin in the Piedmont region; and Calhoun in the Limestone Valley region.
Small grain forage evaluation tests were conducted at four locations in Georgia, which included Tifton and Plains in the Coastal Plain region, Griffin in the Piedmont region and Calhoun in the Limestone Valley region, and at Marianna, Florida.

Ash has been considered a waste product instead of a resource, because few industries have taken advantage of its beneficial properties. Several alternative uses for wood ash have been developed. Land application is one of the best because nutrients taken from the land during harvest are recycled back to the land.

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.
