	How to Convert Liquid Fertilizer into Dry Fertilizer in Fertigation for Commercial Vegetable and Fruit Crop Production (HS1200) In recent years, more and more liquid fertilizers have been used in vegetable and fruit production. Typically, UF/IFAS recommendations are expressed as pounds per acre or kilograms per hectare. Thus, conversion either from a dry fertilizer basis (the UF/IFAS recommendation) to a liquid fertilizer basis, or from a liquid fertilizer source to the UF/IFAS recommended nutrient rate is often required for correct application rate. This 5-page fact sheet helps growers understand the conversion method from liquid to dry fertilizer. Written by Guodong Liu, David Sui, and Gary K. England, and published by the UF Department of Horticultural Sciences, April 2012. http://edis.ifas.ufl.edu/hs1200

	Potato Physiological Disorders – Growth Cracks (HS930/HS182) Growth cracking is an external noninfectious physiological disorder of the potato tuber in which the tuber splits while growing. The split heals but leaves a fissure in the tuber. Growth cracks generally start at the bud or apical end of the potato and can extend lengthwise. They vary in severity from a surface abrasion to a split through the tuber, depending on the stage of growth during which the initial cracking occurred This 2-page fact sheet was written by L. Zotarelli, C. Hutchinson, S. Byrd, D. Gergela, and D. L. Rowland, and published by the UF Department of Horticultural Sciences, May 2012. http://edis.ifas.ufl.edu/hs182
	Potato Physiological Disorders – Brown Center and Hollow Heart (HS945/HS197) Brown center and hollow heart are internal noninfectious physiological disorders of the potato tuber. Brown center is characterized by a region of cell death in the pith of the tuber that results in brown tissue. Hollow heart is characterized by a star- or lens-shaped hollow in the center of the tuber This 2-page fact sheet was written by L. Zotarelli, C. Hutchinson, S. Byrd, D. Gergela, and D. L.

	Proper Use and Handling of Glyphosate in Plant Nurseries (ENH1198/EP459) Glyphosate is the most used herbicide in the nursery industry in the United States. Used for postemergent control of vegetation, it controls annual and perennial grasses, broadleaves, and sedges. But it is easy to cause unintended damage to desirable vegetation if this product is used incorrectly. This 4-page fact sheet outlines the proper use of glyphosate for plant producers and their employees. Written by Shawn T. Steed and Robert H. Stamps and published by the UF Department of Environmental Horticulture, May 2012. http://edis.ifas.ufl.edu/ep459
