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.

Fertilizer Management for Greenhouse Vegetables—Florida Greenhouse Vegetable Production Handbook, Vol. 3

George Hochmuth

Plants require 17 elements for normal growth and reproduction. The objective of a sound fertilizer management program is to supply these required nutrients in ample, but not excessive amounts for optimum crop production. This chapter will present general information on plant nutrition that will be useful irrespective of the particular cultural system e.g., perlite, rockwool, coconut coir, peatmix, or NFT hydroponics used by a grower. Fertilizer programs will be detailed later in this document.

Optimizing Nitrogen Management for Sustainable Tomato Production in North Florida

Laura Jalpa, Rao S. Mylavarapu, George Hochmuth, Yuncong Li, and Bala Rathinasabapathi

Tomato is a vital commercial crop in north Florida, where the unique sandy soils present specific challenges for nitrogen (N) management. This publication evaluates the benefits of using polymer-coated controlled-release urea, which demonstrates a capacity to maintain crop yields comparable to those achieved using conventional fertigation methods and N sources. Our research findings emphasize the importance of adjusting N application rates to align with the crop nitrogen requirement and account for seasonal variability in natural soil mineralization rates. These adjustments are crucial for optimizing nitrogen use efficiency and sustainability in tomato cultivation. The publication offers practical recommendations for local growers on selecting optimal N rates and sources. Additionally, these guidelines aim to enhance the sustainability of commercial tomato production by incorporating advanced fertilizer technologies and precise N management practices tailored to local conditions.

General Aspects of Plant Growth—Florida Greenhouse Vegetable Production Handbook, Vol 3

G. J. Hochmuth

This text discusses the critical factors for achieving profitable greenhouse vegetable production by optimizing plant growth processes, primarily focusing on photosynthesis. Photosynthesis, which converts light, carbon dioxide, and water into sugars and oxygen, is influenced by light intensity, CO2 levels, temperature, and water supply. The text explains that managing these factors—such as using shading to control temperature, enhancing CO2 levels, and ensuring adequate water—can maximize photosynthesis and plant growth. Additionally, it touches on the importance of minimizing nutrient deficiencies, diseases, and mechanical damage to maintain healthy photosynthetic activity. The ultimate goal for greenhouse managers is to balance photosynthesis and respiration to produce high yields of quality vegetables.

Plant Petiole Sap-Testing for Vegetable Crops

George Hochmuth and Robert Hochmuth

Various nitrate and potassium "quick-test" kits for vegetable plant sap-testing have been calibrated for use on Florida vegetables. The objective has been to find a system that growers can use in the field to help manage nitrogen (N) and potassium (K) fertilizer—especially for drip-irrigated vegetables. The following guidelines should help individuals who are currently using—or are interested in using—sap-testing.
