Converting from seepage irrigation to plasticulture for vegetable production: a case study and on-farm demonstration

Figure 6. Soil moisture sensors installed under plastic mulch in both inner and outer plant rows.Cabbage production in Florida has been dominated by the use of seepage or sub-irrigation, because it is inexpensive to maintain and simple to use, but it can require vast quantities of water to be pumped from the aquifer in low rainfall years. Plasticulture has been proposed as an alternative production method for cabbage production in Florida. An on-farm demonstration was setup on Greene’s Farms in Bunnell, FL to provide a platform for collaboration between researchers, growers and extension professionals. This 6-page fact sheet illustrates an innovative approach converting from seepage irrigation to plasticulture and points out some options and challenges for growers considering a plasticulture system.

Candidate Species for Marine Ornamental Aquaculture: Porkfish, Anisotremis virginicus

Figure 1. Adult porkfish.The porkfish is a member of the grunt family, which create a characteristic “grunting” sound by rubbing their pharyngeal teeth together during periods of agitation or courtship. Many species of grunts are popular in public aquariums because they’re abundantly available, and their schooling behavior and bright colors create interest in aquarium exhibits. Porkfish also have additional appeal to aquarists because they are “cleaner” fish during their juvenile phase, picking parasites from larger fish and other vertebrates. Scientists and aquarists have recently achieved a greater understanding of appropriate aquaculture protocols for grunts in general and porkfish in particular. These characteristics and advancements have led to porkfish being identified as a candidate species for commercial aquaculture.

Description of Enhanced-Efficiency Fertilizers for Use in Vegetable Production

Figure 1. Urea-formaldehyde slow-release fertilizer.In response to the Federal Clean Water Act of 1972 and the Florida Restoration Act of 1999, a series of best management practices (BMPs) was implemented to improve surface and ground water quality. BMPs are cultural practices that, when implemented as a plan, help reduce the environmental impact of production while maintaining yield and quality. One of these BMPs includes the use of controlled-release fertilizer, which is an enhanced-efficiency fertilizer. This publication describes the common enhanced-efficiency fertilizers and the factors affecting their use in Florida vegetable production.

Tracking the Economic Benefits Generated by the Hard Clam Aquaculture Industry in Florida

handful of clams The hard clam industry is a true success story for commercial aquaculture in Florida. From a cottage industry borne of reductions in commercial wild clam harvests in the Indian River Lagoon during the late 1980s, hard clam aquaculture has now developed into an industry that is rivaled by no other aquaculture food product in Florida. Although successful by virtually any metric, the risks and uncertainty associated with commercial hard clam culture has led to the evaluation of programs that help mitigate risk, such as the former pilot Cultivated Clam Crop Insurance Program administered by USDA Risk Management Agency. All of this alludes to the economic importance of the hard clam culture industry which, through the cultivation process and sales of products, generates local income and taxes, creates jobs and businesses, and draws new money into the local economy, as cultured hard clams are sold to non-residents and buyers outside the region and state. This 6-page fact sheet provides an overview of a recent study by the University of Florida to provide an estimate of the impact of the hard clam industry to the Florida economy.

The Four Rs of Fertilizer Management

4 R's: right rate, right source, right placement, right timingSupplying needed nutrients for crop production involves attention to four major fertilization factors (the 4Rs): right rate, right source, right placement, and right timing. Attention to these factors will provide adequate nutrition for crop production while minimizing the risk of loss of nutrients to the environment. In this publication each factor is described, as well as how the information can be provided from a soil test report. While not a formal part of the 4Rs, the importance of irrigation to overall nutrient management is stressed in this 4-page fact sheet written by George Hochmuth, Rao Mylavarapu, and Ed Hanlon, and published by the UF Department of Soil and Water Science, October 2014.

Fertilizer Recommendation Philosophies

Figure 2. Incorporating fertilizer for an experiment on fertilizer rate and source for tomato.Farmers receive varying fertilizer recommendations depending on which lab they consult because labs employ different chemical methods and procedures to analyze the samples and subscribe to different fertilizer recommendation philosophies. This 4-page fact sheet explains the main soil-test philosophies, their basis, and their applications, and explains why the Sufficiency Level of Available Nutrient philosophy (SLAN), also called the Crop Nutrient Requirement (CNR), is most likely to be the best to govern fertilizer recommendations in Florida today.

A Farm to School Procurement Calculator for Specialty Crop Producers and School Food Service Staff

Farm to School logoFlorida Farm to School programs are designed to connect producers with schools. But school food service staff make their purchasing decisions in terms of servings and producers pack their products by weight. General calculators and guides designed for national Farm to School programs don’t address Florida’s diverse production of fresh fruits and vegetables. This procurement calculator and guide for Florida Farm to School programs was written by Jonathan A.

Jalapeño and Other Hot Pepper Varieties for Florida

Capsico
The jalapeño is derived from the Capsicum genus of the family Solanaceae. Jalapeños are members of a diverse group, which also include ancho poblano, cayenne, serrano, Anaheim, banana, Asian, habanero, and Hungarian wax peppers. Hot peppers are classified by their heat and shape. The heat of the pepper comes from the chemical compound capsaicin, which is measured by the Scoville scale.

Growth Stages and Tuber Development of FL1867 Potato under Full and Reduced Irrigation Scheduling

Figure 1. Whole plant samples of FL 1867 during the 2012 growing season at 41 DAP (A), 48 DAP (B), 54 DAP (C), 61 DAP (D), 75 DAP (E), and 90 DAP (F).The potato cultivar ‘Frito Lay 1867’ (‘FL 1867’) is a popular chipping variety grown across Florida and the southern United States. Knowledge of the timing and duration of the tuber initiation and tuber bulking stages for ‘FL 1867’ is critical for timing fertilizer and irrigation applications. So to evaluate the start and length of the tuber initiation and tuber bulking stages under Florida growing conditions, ‘FL 1867’ plants were dug up and photographed on a weekly basis from a commercial field near Live Oak, FL in 2012.

Pool Chemicals and Personal Safety

Figure 1. Pool chemicals, distributed through box stores, are classified as pesticides.Pool chemicals are among the most common household substances and are used to protect health in recreational waters. Pool chemicals containing chlorine safeguard against recreational-water illnesses caused by disease-causing pathogens, such as the diarrhea-causing Cryptosporidium. They also enhance disinfection by regulating water pH. But even though these materials are regularly handled by homeowners, most don’t ever realize that they are handling pesticides.

The flagged potato rows were planted with ‘Elkton’; the other rows were planted with 'Atlantic.'The ‘Elkton’ chipping potato variety was tested on a commercial scale at two growers’ farms in Florida during the 2011 season. The average yield of ‘Elkton’ in the commercial trials ranged between 295 and 324 cwt/ac, an average of 11 percent higher than that of the standard ‘Atlantic,’ and comparable to the yield range obtained in 19 trials conducted over a nine-year period by the University of Florida.
