Cover crops and compost can impact soil microbes in citrus groves, and that’s generally considered a good sign, soil microbiologist Sarah Strauss said in a virtual May 24 seminar. Microbes are critical components of soil health through their contributions to soil organic matter, nutrient cycling and plant defenses. But the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
Effects of Compost and Organic Amendments on Weed Control
By Ramdas Kanissery and Mahesh Bashyal Using compost and soil amendments is beneficial to Florida citrus groves. Florida soils are sandy and have a low organic matter and cation exchange capacity. Adding compost and organic amendments (e.g., humic acid) can enhance the soil’s ability to retain water and nutrients. These practices can also boost soil microbial activity and improve soil …
Does Compost Improve Young Tree Growth?
By Ute Albrecht, Gabriel Pugina, Antonio Castellano-Hinojosa and Sarah Strauss Root health is important for tree growth and directly affects a tree’s ability to cope with adverse biotic and abiotic stresses. Most citrus production in Florida occurs on natural infertile sands with very little organic matter and a low cation exchange capacity (CEC), resulting in minimal amounts of soluble nutrients …
Tackling Weeds After Composting
By Ramdas Kanissery The use of compost in tree rows is receiving increasing attention among citrus growers. The use of weed-free certified products can considerably minimize the weed emergence issues associated with compost use. However, eventually, weeds will start to grow in the composted areas in the grove. As compost and similar soil amendments prove to be very rich in …
Compost Use and Weed Management
By Ramdas Kanissery Application of compost as a soil amendment could be an integral part of citrus production’s best management practices. Compost application can potentially improve soil quality and provide additional nourishment to trees. Citrus-producing soils in Florida are generally sandy and low in soil organic matter. Compost addition tends to enhance the soil’s ability to retain both nutrients and …
Soil, Cover Crops and Compost
Soil organic matter benefits citrus, but there isn’t much of it in Florida groves, says University of Florida Institute of Food and Agricultural Sciences soil microbiologist Sarah Strauss. Most Florida citrus land typically contains only 1 to 2 percent soil organic matter, says Strauss, who works at the Southwest Florida Research and Education Center. “Areas near the Everglades with muck …
Use of Compost in Citrus
On May 31 in Bushnell, the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) and Life Soils hosted a field day on the use of compost in citrus. Monica Ozores-Hampton was the featured speaker of the event. She is known as Florida’s “Compost Queen” from her UF/IFAS and US Composting Council research and workshops on compost utilization. She …
All In for Citrus Podcast, April 2025
April is a busy month for citrus events. The Florida Citrus Growers’ Institute was held in Avon Park early in the month followed by a citrus field day at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SFWREC) in Immokalee. These events are the topic of the April episode of the …
Citrus Field Day Highlights Research
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee hosted a citrus field day on April 10. The event showcased the research being conducted at the center. One of the tour stops featured individual protective cover (IPC) research led by Fernando Alferez, UF/IFAS associate professor of citrus horticulture. Thanks in …
Digging Into Methods to Boost Citrus Soil Health
By Sarah Strauss, Emma Dawson, Gabriel Pugina, Ute Albrecht, Jonas Pereira de Souza Junior and Davie Kadyampakeni While soil health has always been considered critical for Florida citrus production, it has increased in importance with the endemic presence of citrus greening (HLB). Soil health is similar to the concepts of soil quality or soil fertility but with an additional focus …
Sneak Peek: March 2025 Citrus Industry
The Citrus Industry section in the March issue of Specialty Crop Grower magazine offers timely information citrus growers won’t want to miss. Now is the time for Florida citrus producers to begin thinking about their disease management programs for the season. Megan Dewdney, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist, offers a foliar disease outlook …
Assessing Tools for Citrus Soil Health
Soil microbiologist Sarah Strauss on Jan. 28 discussed the benefits, challenges and unknowns of cover crops, compost and humic acid for citrus soil health. Strauss is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor at the Southwest Florida Research and Education Center. She pointed out that Florida’s citrus soils are problematic because they are 98% …
Transforming Organic Citrus Production
Organic citrus growing presents unique hurdles in Florida, Texas and other southern states. Poor soil quality, nutrient deficiencies and a limited range of pest control options plague organic production. But the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Davie Kadyampakeni is poised to transform the future of organic citrus growing. He aims to do that with a …
Factors to Consider When Planting a New Grove
Growers have numerous things to think about when planting a new grove. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus genetic improvement specialist John Chater discussed this topic during a recent Citrus & Specialty Crop Expo presentation. Following are highlights from his talk on establishing new varieties in a new citrus grove. PESTS AND DISEASES Soilborne pests …
Citrus Nutrient Management Recommendations Continue to Evolve
When HLB arrived in Florida, it changed the world for citrus growers, and a lot of other things had to change with it. One of the biggest changes has been how growers manage their fertilizer programs. The nutrient recommendations that had been developed by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) before HLB became outdated because …
Enhancing Citrus Nutrient Programs
University of Florida Institute of Food and Agricultural Sciences Extension agent Mongi Zekri recently discussed numerous ways growers can enhance their nutrient programs for better tree and fruit performance. TIPS FOR MAKING ADJUSTMENTS Zekri offered the following tips for adjusting a fertilizer program. SOIL TESTING Soil testing is most effective when done annually, Zekri suggested. “Choose a lab you trust …
Dealing With Drought Stress
By Amir Rezazadeh Citrus trees are not immune to the challenges posed by drought stress. Drought stress occurs when a tree’s water supply falls below its demand, leading to physiological disruptions that can impair growth, development and fruit production. In the dry season, when water scarcity is a prevalent issue in Florida, understanding and managing drought stress in citrus trees …
Optimizing Organic Nutrient Sources
By Davie Kadyampakeni The use of certified organic nutrient sources (manures, composts, biochar, biosolids, etc.) should be considered by Florida commercial citrus growers to improve the soil properties and long-term nutrient availability of the predominantly sandy soils. Use of the organic residues could be incorporated in the soil during tillage to plan a new grove or periodically to an existing …
