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.

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.

Peach Scab

Figure 3. Peach scab lesions on ripening fruit. Lesions occur on the top part of the fruit where water from rain or irrigation splashes spores down on the fruit.Peach scab is a disease caused by the fungus Cladosporium carpophilum. The pathogen can infect other fruits and nuts within the Prunus species, like almonds, apricots, nectarines, and plums. Peach scab is common during periods of humid weather because rain splashes the conidia (asexual spores) from the fungus between leaves, twigs, and fruit in the tree canopy, which spreads the disease.

Pests and Fungal Organisms Identified on Olives (Olea europaea) in Florida

Figure 1. Leaffooted bug, Leptoglossus phyllopus, on an olive tree in Marion County, Florida.Olive production in Florida has increased over the last few years. As trees become available in nurseries many homeowners are planting them in their landscapes. Fortunately, olives are a relatively pest-free species, but some occasional invaders can be a nuisance or cause lasting harm. A few plant pathogens that may infect olives also can lead to a decline in overall plant health, fruit yield, or the visual appearance of plants. Following correct cultural practices when growing olives can reduce your chances of tree loss from pests and diseases. A survey of olive production and interviews with Florida growers in 2014 identified the pests and diseases described in this 5-page fact sheet, written by Jennifer L. Gillett-Kaufman, Sandra A. Allan, Jonael H. Bosques-Mendez, and Lyle J. Buss, and published by the UF Department of Entomology and Nematology, September 2014.

Weed Management Principles in Commercial Vegetable Production

Figure 1.  Wild radish interference in sweet corn Credit: P. J. DittmarWeeds compete with vegetable crops for light, water, and nutrients. This competition decreases plant vigor, yield, and crop quality. They interfere with hand harvest and can complicate or prevent machine harvest. Weeds also serve as alternative hosts to diseases, viruses, and nematodes. A successful weed management program will incorporate multiple control practices with preventative, cultural, biological, mechanical, and chemical methods.

Water Use for Seepage-Irrigated Watermelon with Plastic Mulch in Florida

Figure 1. The drainage lysimeter for the watermelon crop water-use experiment Credit: Shukla et al. (2014)In Florida, watermelon is an important crop that accounts for a significant part of the state’s agricultural water use. Depending on the type of production system and climate, the water use of this crop can vary. In Florida, watermelon is predominantly grown on raised plastic-mulched beds. To develop improved water management and allocation plans, accurate water use estimates for watermelon are needed. Seepage irrigation under plastic mulch is a common production system used to produce watermelon in south and northeast Florida where the water table is shallow. Plastic mulch alters the rainfall entry and soil temperature of the raised beds and can significantly affect evapotranspiration. As there is no information on seepage-irrigated watermelon grown on plastic mulch for subtropical Florida, this 4-page fact sheet summarizes the results from a crop water use study for the seepage-irrigated watermelon in south Florida.

Water Use for Seepage-Irrigated Pepper with Plastic Mulch in Florida

Figure 1. The drainage lysimeter for the pepper crop water-use experiment Credit: Sanjay ShuklaBell pepper (Capsicum annuum) is an important crop for Florida and accounts for a significant fraction of its agricultural water use. Most of it is produced in south Florida, where the water table is shallow. Seepage irrigation is one of the most common systems used in south Florida for growing plastic-mulched vegetable crops, including bell pepper. Compared with an open field production, covering the soil with impermeable plastic reduces soil evaporation and increases transpiration. This 3-page fact sheet summarizes the results from a crop water use study for the seepage-irrigated pepper in south Florida.

Factors Affecting Phosphorus Leaching and Groundwater Concentrations for the Plasticulture Vegetable-Production System

Figure 1. Groundwater total phosphorus (P) and soil Mehlich-1 P (M1P) concentrations for average grower (GI), recommended (RI), and recommended with sub-drip (RI-SD) water and fertilizer P inputs for the period of study (2004–2006). Groundwater samples were collected biweekly during crop season, and M1P samples (0–20 cm) were collected before and after crop season. Dotted lines show second order polynomial trend for P concentration over the period of study for each treatment.Although Best Management Practices (BMPs) have been developed to reduce the loss of nutrients, like P, to the environment, limited information exists on the main factors that control P loss to Florida groundwater. For example, while it is generally accepted that both irrigation and fertilizer P impact groundwater P, growers often ask if controlling one is more advantageous than the other in their efforts to reduce P leaching. There exists no easy tool to link fertilizer P input and other factors to groundwater P concentration. This 5-page fact sheet uses long-term data (six growing seasons) from a farm in Immokalee, Florida, to explain the effects of soil and agronomic factors, along with seasonal rainfall, on groundwater P. From these factors are derived simple equations to predict groundwater P concentrations. Written by Sanjay Shukla, Gregory S. Hendricks, Thomas A. Obreza, and Willie Harris, and published by the UF Department of Agricultural and Biological Engineering, August 2014.
