The objective of a new study published in HortScience was to evaluate and understand the nutrient uptake potential of citrus rootstocks. Conducted by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, it is one of the first citrus studies to report nutrient uptake efficiency and the potential of rootstocks. The information presented in the study can be …
Winter Storm Elliott brought freezing temperatures to the cold-hardy region Dec. 24–28, 2022, resulting in significant injury to citrus. Danielle Williams, Muhammad Adnan Shahid and Mujahid Hussain, all with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), provided storm recovery advice in a recent edition of the Cold Hardy Citrus Connection newsletter. Following is a summary of …
By Ajia Paolillo There is no crystal ball when it comes to anything in life, including agriculture. Growers are at the mercy of Mother Nature’s glory and fury. Over time, the citrus industry has developed production techniques and practices to help during the hard times. Microsprinkler irrigation is used both to provide targeted, much needed water during bloom, fruit set …
Mexican orange production in 2022–23 is forecast at 4.2 million metric tons (MMT), 9% lower than the previous year, due to prolonged drought in northeastern Mexico. The forecast was issued by the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS). Mexico is estimated to be the fifth-largest orange producer in the world behind Brazil, China, India and the United …
IMG Citrus, based in Vero Beach, Florida, has acquired J&J Fresh Produce assets. These assets, also located in Vero Beach, include a new 185,000-square-foot cold storage and packaging facility and 1,000 acres of farmland in the Delta Farms Water Control District. “This is an exciting acquisition and a key component of our growth strategy,” said Melanie Ressler, co-chief executive officer …
Chemical Dynamics is a leading provider of crop nutrition solutions, focused on helping farmers grow specialty crops in Florida, the Southeast and across the US. Our company was founded in 1973 by W.B. “Hap” Carson in Plant City, FL and has been a family-owned and operated business for three generations. For the past 50 years, we have developed a diverse …
By Amir Rezazadeh Cover crops protect the soil from sunlight, wind and heavy rain, which enhances soil microbial populations and improves soil structure, water infiltration and root penetration. A reduction in soil crusting, erosion, runoff and nutrient leaching are additional advantages. Through improved nitrogen cycling and nutrient retention, cover crops increase soil fertility. ORGANIC MATTER SOURCECover crops offer an inexpensive …
Alico, Inc. recently summarized its second sustainability report. President and Chief Executive Officer John Kiernan said the company over the past year has delivered environmental, social and governance (ESG) promises made in its first sustainability report in 2021. He cited the following as some of Alico’s notable accomplishments: “Our goal with this report is to make it easier for our …
The late citrus grower John T. Moose left the largest individual gift ever to the University of Florida Institute of Food and Agricultural Sciences Indian River Research and Education Center (UF/IFAS IRREC) in Fort Pierce. The $260,000 contribution came in 2022, the same year as the center’s 75th anniversary. The gift will help serve local agriculture and natural resources protection …
By Tripti Vashisth, Faisal Shahzad and Jamie Burrow Leaf nutrient analysis is an important part of a successful citrus management program. Good fertilization practices are critical for optimal crop production, especially in HLB conditions. The two main objectives of nutrition management in citrus are 1) optimum and consistent yield and 2) building a strong tree that grows and produces year …
High yields of HLB-free fruit can hypothetically be sustainably produced in citrus under protective screen (CUPS), Arnold Schumann said at a Dec. 14 field day at the Citrus Research and Education Center (CREC). He backed that up with data showing high yields from Ray Ruby grapefruit planted at high densities and fertigated in CUPS. Trees in his CUPS facility are …
By Mongi Zekri For maximum efficiency of a grove, it is essential that every location is occupied by a tree and that every tree is healthy. Prompt replacement of dead and declining trees means higher average long-term returns from the grove. If the declining trees remain in the grove, they keep getting weaker and yield less fruit each year. Therefore, …
Norwegian company Desert Control has developed a liquid natural clay (LNC) that reportedly restores and enhances soil ecosystems to reduce usage and improve efficiency of water, fertilizers and natural resources for agriculture and other uses. It has signed contracts with the Limoneira Company to apply LNC to citrus trees in California and Arizona. The project’s initial scope is to apply …
By Tripti Vashisth In Florida, it is the time of year to start following citrus flower bud induction conditions for next year’s bloom. Citrus flower bud induction starts in the fall and usually is complete by early January. Low temperatures first stop growth and then promote induction of flower buds as more hours of low temperatures accumulate (below 68 degrees). …
By Mongi Zekri Pruning is an important grove practice that increases sunlight penetration within the tree canopy. Sunlight enhances flowering, fruit quality and color development. Sunlight also allows foliage to dry quickly after a rain shower, which reduces problems of fungal diseases. Pruning trees can improve fruit quality and increase fruit size. However, tree response to pruning depends on scion …
The Fruit Crop Physiology Lab at the North Florida Research and Education Center (NFREC) in Quincy is focused on developing a sustainable and profitable cold-hardy citrus industry in the southern United States. To do that, it is conducting research-driven Extension projects. The NFREC is part of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The lab collaborates …
By Chris Oswalt Growers may have compelling reasons to collect and analyze citrus leaf samples at different times of the year. Current tables allow growers to interpret the results of their citrus leaf analysis based on the collection and analysis of 4- to 6-month-old leaves from non-fruiting twigs (Figure 1). This begs the question of the potential consequences of interpreting …
Dundee Citrus Growers Association (CGA) and its members will more than double the area growing fresh citrus under protective screen (CUPS) with the addition of a second CUPS project. The new project will be located in southern Polk County, just east of Fort Meade. “Once fully developed, the 622-acre parcel will contain approximately 500 acres of CUPS … bringing our …
By Yiannis Ampatzidis and Sandra M. Guzmán Pests and diseases, nutrient deficiencies, tree stress from environmental conditions and other factors can be overwhelming. The arrival of sensors and small unmanned aerial vehicles (UAVs) make it possible to gather large amounts of data to assess risk factors and estimate possible crop performance scenarios based on the availability of resources. At the …
Whether a citrus grove is thriving or not is often based on what is observed above the ground. However, the best measurement of fertility comes from what’s happening below ground—in the soil microbiology. There is a complex community of living organisms, everything from worms and insects to tree roots. One of the most important elements is soil microbes. Soil microbes …
