How to Convert Liquid Fertilizer into Dry Fertilizer in Fertigation for Commercial Vegetable and Fruit Crop Production (HS1200/HS1200)

 Figure 3.  A 3-3-3 liquid fertilizer label. 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.

Lettuce Cultivars for Insect Resistance in Southern Florida (HS1196/HS1196)

Russell Nagata, associate professor at the University of Florida's Institute of Food and Agricultural Sciences at Belle Glade, Florida , examines leafminer colonies on romaine lettuce. He is using genetic engineering to make lettuce resistant to the tiny leafminer insect that tunnels through leaves and makes lettuce unmarketable. The improved lettuce will lower pesticide cost for growers and produce higher quility lettuce for consumers. Photography by Milt PutnamFlorida’s subtropical climate facilitates lettuce production from fall through spring, but the warm, moist conditions are also favorable for insect proliferation and damage. Information about current cultivar response to common insect pests in Florida is limited, so UF/IFAS researchers conducted a study to evaluate cultivar response to insect infestation under field conditions and to identify resistance useful for integrated pest management. This 4-page fact sheet was written by Huangjun Lu, Alan L. Wright, and David Sui, and published by the UF Department of Horticultural Sciences, February 2012.

SL323/SS535 Spring Mix: An Emerging Crop for Florida

SL323, a 3-page illustrated fact sheet by Santiago Rosaro, Alan L. Wright, David D. Sui, Nikol Havranek, and Yigang Luo, describes the components of spring mix, explains the reasons why consumers are looking for these mixes, and why growers in the Everglades Agricultural Area of Florida are producing them.

SL290/SS503 Persistence of Plant-Available Phosphorus in Muck Soils after Fertilizer Application

SL-290, a 5-page fact sheet by Alan L. Wright, Edward A. Hanlon, J. Mabry McCray, and David D. Sui, provides growers in the Everglades Agricultural Area with information about the organic soils in southern Florida and their management to improve crop production while also reducing adverse environmental effects, especially during times of land use change.
