To maintain balanced nutrients for optimal tree growth, citrus growers need to assess trees’ nutritional requirements. These assessments help prevent any nutrient deficiency or toxicity from compromising tree health and yield or reducing revenue. This new illustrated two-page instructional sheet gives a basic procedure for the citrus leaf sampling process, as well as additional suggestions for HLB-affected trees. Written by Tripti Vashisth, Jamie D. Burrow, Davie Kadyampakeni, and Rhuanito S. Ferrarezi, and published by the UF/IFAS Horticultural Sciences Department.
To achieve optimal grove nutrition, citrus growers must test grove soil before beginning any fertilization program. Standard procedures for sampling, preparing, and analyzing soil should be followed for meaningful interpretations of the test results and accurate recommendations. This new two-page fact sheet, published by the UF/IFAS Department of Soil and Water Sciences, provides illustrated soil sampling procedures and tables to aid in basic interpretation of lab results. Written by Davie Kadyampakeni, Kelly Morgan, Arnold Schumann, and Rhuanito S. Ferrarezi.
This updated 4th edition of the Florida Citrus Rootstock Selection Guide (FLCRSG) is a revision of the 2016 publication. The guide is a convenient, easy-to-use reference to 21 characteristics of 49 rootstocks. Of those, 12 are time-honored commercial rootstocks (highlighted in blue), which are the most reliably characterized. The next 13 rootstocks are minor commercial ones (highlighted in green) that are less frequently used today in Florida but may have been prominent at one time. The third group consists of the most recently released 24 rootstocks (highlighted in yellow) for which there is limited commercial experience. The new addition includes three new USDA rootstocks and updates information on a few traits. Written by William S. Castle, Kim D. Bowman, Jude W. Grosser, Rhuanito Soranz Ferrarezi, Stephen H. Futch, and Steve Rogers, and published by the UF/IFAS Horticultural Sciences Department.
Citrus tree production in nurseries can be divided into three stages: production of rootstock liners, transplant of rootstocks into larger containers, and bud grafting. The objectives of this new 6-page publication of the UF/IFAS Horticultural Sciences Department are to provide general information on irrigation and fertilization for production of citrus nursery trees in seedbeds, nurseries and budwood multiplication blocks. This article, written by Rhuanito Soranz Ferrarezi, is chapter 8b of the forthcoming Citrus Nursery Production Guide.
