This new 6-page publication of the UF/IFAS Department of Soil and Water Sciences is intended to address agronomic and environmental issues related to phosphorus (P) dynamics in Florida agricultural soils and soil test P interpretation and management for agricultural crops. This document aims to provide science-based information to agricultural clientele, including commercial producers, small farmers, Extension agents, crop consultants, landscape professionals, representatives of the fertilizer industry, state and local agencies, students and instructors of high schools and colleges, researchers, and interested Florida citizens. Written by Rao Mylavarapu, Yuncong Li, Maria Silveira, Cheryl Mackowiak, and Mabry McCray.

2011 South Florida Beef Forage Survey Results

Young heifers at the Range Cattle Research Station. These beef cows are all at least 3/4 Angus. They are part of an attempt to create a white Angus breed. During the summer the white cows, coined "white Angus" by the researchers in Ona, have a body temperature that is one degree cooler than the traditional black Angus. UF/IFAS Photo: Sally Lanigan.UF/IFAS Extension faculty and state specialists involved in the UF/IFAS South Florida Beef-Forage Program (SFBFP), in conjunction with the UF/IFAS Program Evaluation and Organizational Development unit, created a survey in 1982 that is used to evaluate ranch management practices. The survey is updated and distributed every five years to ranchers in 14 south Florida counties: Charlotte, Collier, DeSoto, Glades, Hardee, Hendry, Highlands, Hillsborough, Lee, Manatee, Martin, Okeechobee, Polk, and Sarasota. There were 102 anonymous responses in 2011. This 6-page fact sheet discusses characteristics of beef operations in south Florida, reproduction, production, marketing, herd health, nutrition, forage production, and environment. Written by Sonja Crawford, Christa Kirby, Tycee Prevatt, Brent Sellers, Maria Silveira, Bridget Stice, Joao Vendramini, and Lindsey Wiggins, and published by the UF Agronomy Department, October 2016.

Soil and Plant Tissue Testing

Soil Sampling. Soil testing is the best tool for monitoring soil fertility levels and providing baseline information for cost-effective fertilization programs. But a major limitation is that it typically accounts for the plant-available nutrient pool present in the surface soil layer. Because of the extensive root system in some plants, plant analysis is a complement to the soil test to better assess the overall nutrient status of a perennial forage system, while revealing imbalances among nutrients that may affect crop production. This 4-page fact sheet was written by Maria L. Silveira, and published by the UF Department of Soil and Water Science, June 2014.

Mulato II (Brachiaria sp.) (SSAGR303/AG310)

Mulato II is a semi-erect perennial apomictic grass that can grow up to 9 ft tall. Brachiariagrasses, including Mulato II, are tropical warm-season forages native to Africa and are the most widely grown forages in tropical South America. This 4-page fact sheet describes teh morphology, region of adaptation and growing season in Florida, recommended production practices, and the results of research into the performance of heifers grazing Mulato. Written by J. Vendramini, B. Sellers, L.E. Sollenberger, and M. Silveira, and published by the UF Department of Agronomy, March 2011.

SL292/SS505 Soil pH and Liming Issues Affecting Bahiagrass Pasture

Revised! SL-292 (formerly SS-AGR-29), a 5-page fact sheet by M. Silveira, J. Vendramini, J. E. Rechcigl and M. B. Adjei, presents results of research conducted to evaluate the long-term effect of liming and N fertilization on dry matter yields, nutritive value, and ground cover of bahiagrass pastures. Includes liming and fertilization recommendations for grazing conditions in south-central Florida flatwoods. Published by the UF Department of Soil and Water Science, September 2009.
