Fertigation for Citrus Trees

Microirrigation is an important component of citrus production systems in Florida. For citrus trees, microirrigation is more desirable than other irrigation methods for several reasons: water conservation, fertilizer management efficiency, and freeze protection. Research has shown that when microirrigation systems are properly managed, water savings can amount to as much as 80% compared with subirrigation and 50% compared with overhead sprinkler irrigation. Research has also shown the important advantage of microsprinklers for freeze protection of citrus. This 4-page fact sheet discusses fertilizer solubility and some common fertigation materials. It also offers a fertigation summary.

Flatwoods Citrus Best Management Practice: Riser-Board Structures

Figure 2. Typical riser-board structure within a citrus grove drainage system. Water discharge structures are used to control water table levels and surface water levels in drainage and irrigation ditches within flatwoods citrus groves. The type of structure selected can significantly influence the quality of water discharged. With flashboard risers, water is forced to flow over the top board. This flow path creates a low current area toward the bottom, which facilitates the deposition of sediments and their accompanying nutrients or pesticides, essentially removing them from the discharges. Conversely, screw-gate structures do not create this dead-current zone. Since they open from the bottom, sediments are swept out along with the discharge water.

Flatwoods Citrus Best Management Practice: Soil Stabilization

This best management practice describes stabilization practices for erosion-prone soils within flatwoods citrus groves. Significant amounts of soil may be deposited in drainage ditches and canals because of the erosion of grove soils. These deposited soils reduce the capacity for holding and transporting water. Plus, very small soil fractions may be suspended in discharge water then settle out in slower flowing areas and destroy submerged aquatic habitats, resulting in the loss of fish, invertebrate, and plant species important for healthy ecosystems. Fortunately, a variety of slope stabilization methods are available. This publication describes considerations for using plants for stabilization, or mulch-like materials. Written by P. Chris Wilson, Liberta Scotto, Brian Boman, and Tim Gaver. Original publication date March 2002. Revised April 2012 and August 2014. Reviewed August 2015.

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

Figure 1. The drainage lysimeter for watermelon experiment Credit: Sanjay ShuklaWatermelon is an important crop in Florida and accounts for a significant part of its agricultural water use. Watermelon is grown in open fields and on raised plastic-mulched beds, with the latter being the predominant production system in Florida. Accurate water use estimates for this crop are needed to develop better water allocation and management plans as well as for irrigation management. This publication summarizes the results from a crop water-use study for the drip-irrigated watermelon in south Florida. This 3-page fact sheet was written by Sanjay Shukla, Niroj K. Shrestha, Thomas A. Obreza, and Brian J. Boman, and published by the UF Department of Agricultural and Biological Engineering, August 2014.
