By Ute Albrecht, Ankit Pokhrel, Sarah Strauss and Ramdas Kanissery The soils in most Florida citrus production areas are sandy. They have less than 1% organic matter and a low cation exchange capacity (CEC). This makes them prone to nutrient leaching, especially after heavy rainfall events in the summer. HUMIC SUBSTANCESOne way to improve soils is by amending them with …

By Brandon White Taking a wholistic, helicopter view of nutrient management programs can be beneficial in reducing high input costs and environmental implications in the continued era of HLB. START WITH THE SOILAn obvious first stop on the considerations list is the soil. It’s the foundation of the system. Almost any economically feasible thing growers can do to improve organic …
Federal legislators have followed through on previously announced plans to try to overturn the Department of Labor’s (DOL) rule to determine wages for temporary foreign agricultural workers under the H-2A program. H-2A workers harvest a majority of Florida’s citrus crop.

By Rhuanito S. Ferrarezi and Mark A. Ritenour Citrus under protective screen (CUPS) is a modern production system that excludes the Asian citrus psyllid and, consequently, the devastating disease citrus greening (huanglongbing or HLB) from plants cultivated in screenhouses. A recent study investigated the effect of different irrigation management strategies on fruit yield and quality of grapefruit grown in CUPS. …
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.
