Fertilization of Strawberries in Florida

Shinsuke Agehara and George Hochmuth

Strawberry is an important crop in Florida, produced as an annual crop on plastic-mulched beds with drip irrigation. The main production area is in west-central Florida, including Hillsborough, Polk, and Manatee counties. Fertilizer is becoming a more significant portion of strawberry production costs, hence, proper fertilizer management is important for minimizing production costs and maximizing yield and fruit quality, while minimizing potential negative impacts on the environment caused by leaching or runoff of excess fertilizer nutrients. This guide summarizes the recent history of strawberry fertilization research and presents the updated research-based fertilizer management recommendations for strawberry production in Florida.

Nutrient Management Recommendations Based on Mehlich-3 Extractant for Calcareous Soils in Miami-Dade County

Yuncong Li, Qiang Zhu, Rao Mylavarapu, Kelly Morgan, Guodong Liu, Jonathan Crane, Qingren Wang, Henry Mayer, Jeff Wasielewski, Laura Vasquez, Qingchun Liu, and Teresa Olczyk

This factsheet provides information about the history of soil testing calibrations and justification for recommending extraction of soil nutrients using Mehlich-3 for calcareous soils in Miami-Dade County. The dominant soils from this County have an extraordinarily high concentration of calcium resulting in high pH. This document also includes UF/IFAS approved Mehlich-3 extractant-based testing interpretations and recommendations for these soils. The purpose of this publication is to elucidate an appropriate approach for analyzing the unique calcareous soils from Miami-Dade County for plant available nutrients. The target audiences are Extension agents, agronomists at soil testing laboratories, crop advisors, growers, representatives of the state and local agencies, and others concerned about soil testing and plant analysis in Miami-Dade County.

Homeowner Best Management Practices for the Home Lawn

Alex J. Lindsey, Marco Schiavon, J. Bryan Unruh, and Laurie E. Trenholm

A healthy lawn is an important component of an urban landscape. Not only do lawns increase the value of a property, but they also reduce soil erosion, filter stormwater runoff, cool the air, and reduce glare and noise. A healthy lawn effectively filters and traps sediment and pollutants that could otherwise contaminate surface waters and groundwater. This publication is intended for those who maintain their own lawn and landscapes.
