By Ajia Paolillo To keep your irrigation system running efficiently, it is important to perform routine maintenance throughout the year. There are many types of issues that can affect your irrigation system, causing it to run poorly. Poly tubing and emitters can become clogged. Emitters can be blocked by weeds or broken through normal wear and tear. When these issues …
By Davie Kadyampakeni Proper irrigation scheduling applies an appropriate volume of water to a citrus grove at the appropriate time based on tree need, soil properties and weather conditions. Applying water in the right amount, right quantity and at the right time is very important for getting the best out of citrus trees. Several tools are available for determining when …
California citrus growers and other farmers in the Bakersfield area may feel vindicated with the result of a new study by researchers at Duke University and RTI International. As reported in the California Department of Food and Agriculture Planting Seeds blog, the study finds that reusing oilfield water that’s been mixed with surface water to irrigate farms in the Cawelo …
By Sandra M. Guzman and Rhuanito S. Ferrarezi Irrigation scheduling has been one of the most important management practices to improve crop production. For citrus, there are multiple options to schedule irrigation, including evapotranspiration-, plant- and soil-based methods. These methods can provide different water requirement estimates based on environmental variables, plant uptake or water content in the soil. Although each …
By Davie Kadyampakeni and Arnold Schumann Irrigation system maintenance is critical for proper and efficient delivery of water in citrus and other irrigated crops. A well maintained and functional irrigation system will deliver the required amounts of water to the root zone when needed and help growers optimize crop production. If an irrigation system is not working optimally, crops can …
Water is a limiting factor in Florida citrus production during the majority of the year. Florida citrus trees may require irrigation throughout the year due to the low water-holding capacity of sandy soils and the warm subtropical climate with distinct drought periods during the spring. Davie Kadyampakeni, assistant professor of soil and water sciences at the University of Florida Institute …
By Davie Kadyampakeni, Arnold Schumann, Mongi Zekri and Chris Oswalt Irrigation management is important for achieving optimal citrus tree growth and promoting high water- and nutrient-use efficiencies in young trees. In the era of HLB, poor water-management practices, such as infrequent irrigation, lead to water stress in trees resulting in limited growth and impaired root development. On the other hand, …
Three meetings this week in three different areas of the state brought more discussion that should wake up producers and others in agriculture who have remained mostly silent for decades. As the state’s population continues to swell by a 1,000 new residents each day, Florida’s population will likely exceed 22-million next year. As the nation’s third most populous state, there’s …
Daily irrigation is important in managing HLB-affected trees, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil scientist told a Citrus Nutrition Day crowd in Bartow on Dec. 11. The researcher, Davie Kadyampakeni, said daily irrigation reduces tree water stress and improves tree water use. According to Kadyampakeni, keeping water in the top 12 inches of soil …
Savings in water and fertilizer, along with faster tree growth, can be achieved by using subirrigation in citrus nurseries. University of Florida Institute of Food and Agricultural Sciences researcher Rhuanito (Johnny) Ferrarezi reported on the studies leading to those conclusions at a recent citrus nursery workshop. The event was held at the Citrus Research and Education Center in Lake Alfred, …
Mature citrus trees affected by the bacterial disease huanglongbing (HLB) typically need about 25 percent less irrigation than their healthy counterparts However, that doesn’t necessarily mean young trees with the disease will benefit from water deficits, according to a preliminary greenhouse study by researchers with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Experiments on 1-year-old orange …
By Mongi Zekri, Davie Kadyampakeni, Tripti Vashisth, Kelly Morgan, Tom Obreza and Brian Boman 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 properly managed, water savings with microirrigation systems can …
As Florida citrus growers look to recover from the damages of Hurricane Irma and continue to cope with citrus greening, University of Florida (UF) scientists suggest using a complete and balanced nutrient program in their groves. “Mineral nutrition plays a vital physiological role in the growth and development of a plant and as well as in plant-defense response,” said Tripti …
By Marshall Hartley At Florida Southern College, I remember doing an experiment using a large washtub with holes in the bottom. We filled the tub with very dry sand and then poured 1 inch of water over the sand and let it soak in. The water did not travel through the sand evenly. Instead, the water would find one area …
By Arnold Schumann, Laura Waldo, Davie Kadyampakeni, Rhuanito Ferrarezi and Chris Oswalt Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities, and the warm subtropical climate with distinct drought periods in spring. A soil water sensor system can provide the most reliable data for effective citrus irrigation scheduling in these …
The Florida Department of Agriculture and Consumer Services (FDACS) Office of Agricultural Water Policy has a new citrus cost-share program to assist with irrigation improvements on groves that are being replanted. FDACS announced it has set aside roughly $3 million for the Citrus Renovation Irrigation Support Program (CRISP). The program is designed to be a 75 percent cost share for the …
By Len Wilcox California’s consistent sunshine makes for long growing seasons and allows tremendous varieties of foods to be grown, but it isn’t a perfect environment. Chronic water shortages create challenges for everything except cactus grown for tequila or jelly — but not many growers specialize in that. The rest of them, including citrus growers, have to deal with water …
Growers can use these tips and tools for trees impacted by HLB and Hurricane Irma. By Davie Kadyampakeni, Kelly Morgan, Mongi Zekri, Rhuanito Ferrarezi, Arnold Schumann and Thomas A. Obreza Water is a limiting factor in Florida citrus production during the majority of the year. This is because of the low water-holding capacity of sandy soils resulting from low clay …
University of Florida Institute of Food and Agricultural Sciences researcher Davie Kadyampakeni offers water and nutrient management tips for HLB-affected trees. He was a presenter at a recent citrus nutrient management seminar in Immokalee hosted by multi-county citrus Extension agent Mongi Zekri. The seminar drew approximately 60 people to the Southwest Florida Research and Education Center. Kadyampakeni’s tips include …
By Arnold Schumann and Laura Waldo Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities and the warm subtropical climate with distinct drought periods in spring. Citrus trees are evergreen and may be actively growing at any time, with no true dormant phase. HLB-affected trees are particularly prone to multiple …
