The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted a water and nutrient management workshop at the Citrus Research and Education Center in mid-February. In addition to seminars, a grove tour was provided to demonstrate a nutrient-rate trial currently underway at the center. Kelly Morgan, UF/IFAS professor of crop nutrition, spoke on recent activity to update citrus …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has launched a new online graduate certificate program for agricultural professionals. “The certificate program is called Fertilizer Science and Technology, offered completely online at the student’s pace and oriented to growers, consultants, suppliers and regulators,” says Kelly Morgan, UF/IFAS professor of soil fertility and water management. The certificate is …
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 …
By Kelly T. Morgan, Davie Kadyampakeni and Tripti Vashisth This article reviews current University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus fertilizer recommendations and provides updated information about recently approved recommendations for secondary macronutrients and micronutrients. Citrus growers have been very concerned about fertilizer applications and nutrient management since citrus greening (huanglongbing or HLB) was found in …
Need the latest nutrient recommendations for growing citrus in Florida? Find updates for nutrient best management practices in the December issue of Citrus Industry magazine. The article, by Kelly Morgan, Davie Kadyampakeni and Tripti Vashisth, details recently approved recommendations for secondary macronutrients and micronutrients. The new advice is based on University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
The element silicon, known to be beneficial to many plants, is being evaluated for advantageous effects on North Florida citrus and blackberries. Horticulturist Muhammad Shahid discussed the benefits of Earth’s second-most-abundant element (after oxygen) during a recent Cold-Tolerant Citrus Production Workshop in Perry, Florida. Shahid is a University of Florida Institute of Food and Agricultural Sciences assistant professor at the …
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 …
Borates Today recently issued a news release titled Citrus Fruits and Boron: What You Need to Know. A summary follows: Boron is a trace element used in the production of citrus fruits. It is required for proper plant development and preserving consistent fruit yield and quality. The element has a role in flower initiation, pollen germination, nitrogen metabolism, hormonal influences …
At the Citrus & Specialty Crop Expo, Davie Kadyampakeni recommended what he termed “high-efficiency fertilizers” to improve canopy, fruit yield and juice quality, especially in HLB-affected trees. Kadyampakeni is an assistant professor specializing in citrus water and nutrient management the University of Florida Institute of Food and Agricultural Sciences. FOUR TYPESKadyampakeni described four categories of high-efficiency fertilizers: Slow-release fertilizer (SRF) …
Citrus growers have been watching developments with water regulation closely in recent years. The 2022 Florida legislative session addressed some issues that had developed with the state’s best management practices (BMPs) program. Ernie Barnett, president of the Florida Land Council, gave Citrus & Specialty Crop Expo attendees a recap of the BMPs changes and provided a big-picture perspective of the …
By Davie Kadyampakeni Nutrients are needed for optimal citrus tree growth, fruit yields and juice quality. Any nutrient deficiencies could result in low yields and decreased revenue. Make sure citrus trees receive adequate macronutrients and micronutrients at all times. Macronutrients are those nutrients needed in large quantities to influence yield, growth and fruit quality. Macronutrients are further divided into two …
There 17 essential elements that plants need to grow. Three of those elements come to plants via water and the atmosphere. The 14 other elements come from fertilizer applications. Almost all of those are dependent on soil pH to determine how well they are picked up by plants’ root systems. Getting the soil pH just right was discussed in the …
By Jamie D. Burrow and Tripti Vashisth With the increased cost and limited availability of fertilizer, purchasing decisions are more important now than ever. Collecting the right leaves for sampling is the first step to making fertilizer decisions. Leaf samples should consist of 100 leaves that are 4- to 6-month-old spring flush leaves taken from nonfruiting branches. WHY LEAVES FROM …
Florida Citrus Mutual Executive Vice President/CEO Mathew Joyner announced that Gov. Ron DeSantis signed SB 1000, the Nutrient Application Rates bill. Joyner called SB 1000 “a critical piece of legislation.” See the full text of the new law here. The law takes effect July 1. “Sponsored by Senator Ben Albritton and Representative Lawrence McClure, the bill had previously passed both …
Rootstock selection and fertilization are important for those considering growing finger limes in Florida. University of Florida Institute of Food and Agricultural Sciences horticulturist Tripti Vashisth addressed both of those topics in a recent virtual Finger Lime Symposium. Vashisth concluded that Volkamer lemon, UFR-5 and US-802 rootstocks appear promising for finger limes. She noted that a vigorous rootstock influences tree …
In the quest to keep HLB-infected citrus trees productive, many growers are turning to techniques to improve soil health. That’s the focus of the June issue of Citrus Industry magazine. The hope is that better soil health will lead to better tree health. Methods under study include compost, cover crops and oak mulch. Citrus grower and consultant Brad Turner makes …
By Brandon White This time of year is the end of the peak nutrient demand for citrus trees. Regardless of the types of fertilizer or inputs applied in the groves, trees have been taking up nutrients while growing in full tilt during the spring season. One of the greatest factors determining how well trees take up nutrients is soil pH. …
While sending citrus tissue samples to the lab for analysis remains important, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has developed a smartphone application (app) that can supplement lab analysis to identify leaf symptoms of key nutrient deficiencies and certain pests and diseases. Arnold Schumann, a professor of soil and water science with UF/IFAS, demonstrated how …
By Davie Kadyampakeni and Evan Johnson In the era of citrus greening disease (huanglongbing, HLB), maintaining optimal nutrition and disease/pest management strategies is critical for avoiding adverse effects on tree performance. Use of the right fertilization rate, timing and placement are important for optimal citrus production. In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
By Ariel Singerman and Stephen H. Futch Chemical input prices have increased significantly over the last year. In particular, the price of fertilizer has roughly doubled during the last 12 months, as denoted by Figure 1. Figure 1.
