Assessing Nitrate Leaching in Crop Production through the Application of Crop Simulation Models with Experimental Data from FloridaLakesh K. Sharma, Rishabh Gupta, Lincoln Zotarelli, and Gerrit HoogenboomLysimeters are often used in research concerning nutrient leachate all over the globe. However, due to factors such as Florida's high water table (a condition when the water level stays relatively close to the soil surface) in some production areas, the assessment and collection of leachate are not feasible. Another obstacle to the use of lysimeters in field research is the fact that several types of irrigation methods are used in Florida (e.g., subirrigation with seepage or drain-tile, overhead, microsprinkler, and drip irrigation) requiring different strategies for leachate assessment. This publication focuses on the use of crop models as alternatives to estimate nitrate leaching from cropping systems at a field scale. This publication's target audience is growers, extension agents, crop consultants, representatives of the fertilizer industry, state and local agencies, students, instructors, researchers, and interested Florida citizens.

Nutrient Management in Low-Chill Peach Orchards: Guidelines for Deficiency Symptoms and Leaf and Soil SamplingJonathan Clavijo-Herrera, Ali Sarkhosh, Lincoln Zotarelli, Cheryl Mackowiak, and Rao S. MylavarapuTimely and informed fertilization practices in peach production are essential to obtain high yields, optimal fruit quality, and secure long-term orchard health and productivity. Recognizing nutrient deficiency symptoms can help identify which nutrients a plant may be lacking, but a solid nutrient management program should regularly test soil and foliar samples to detect issues before symptoms appear. This publication provides suggested nutrient sufficiency ranges for peach trees, along with practical guidelines for identifying nutrient deficiency symptoms and conducting soil and foliar sampling in the orchard. Its goal is to support county Extension agents and faculty, growers, and homeowners with general and practical guidelines for optimizing nutrient management in peach orchards.

Glossary of Site-Specific Nutrient Management TermsLauri Baker, Jay Capasso, Osvaldo Gargiulo, Lauren Geiss, Emma Matcham, Kelly Morgan, Ricky Telg, and Lincoln ZotarelliThis glossary provides clear, unified definitions for terms and is intended to help aid communication with nutrient management professionals across the state, especially when sharing new site-specific nutrient management recommendations. This glossary should help lessen confusion on how the listed terms are defined and interpreted, thereby helping to improve communication within and across disciplines. Written by Lauri Baker, Jay Capasso, Osvaldo Gargiulo, Lauren Geiss, Emma Matcham, Kelly Morgan, Ricky Telg, and Lincoln Zotarelli, and published by the UF/IFAS Department of Agronomy, April 2025.

Cultivando Papas en el Jardín de su Hogar en la FloridaChristian T. Christensen, Joel Reyes-Cabrera, Lincoln Zotarelli, Wendy J. Dahl, Doug Gergela, Jeffery E. Pack, James M. White y Chad M. HutchinsonEl texto describe cómo cultivar papas en el jardín de casa en Florida. Explica que las papas, un cultivo de estación fría, se siembran en invierno y primavera. Detalla las etapas de crecimiento, desde el brote hasta la maduración del tubérculo, y menciona las variedades populares en Florida, como ‘LaChipper’ y ‘Red LaSoda’. También aborda la preparación del suelo, la fertilización, el riego, el control de malezas, insectos y enfermedades, y la cosecha y almacenamiento de las papas. Además, destaca el valor nutricional de las papas y la importancia de evitar el consumo de papas verdes debido a su toxicidad. Fecha de primera publicación: mayo 2016
