See tips guided by UF/IFAS research on soil sampling for a good fertilization program in Florida citrus.
“Soil sampling is one of two keys to building a good citrus fertilization program…” advised a Citrus Industry article about a publication authored by UF/IFAS researchers on soil sampling for a good fertilization program; the publication was aimed at cold-hardy citrus, but the recommendations are suitable for any citrus grower looking to utilize soil sampling to guide their fertilization program. See the advice below.
Tips on Soil Sampling for a Good Fertilization Program
The article maintained that “effective nutrient management is critical for encouraging plant growth, fruit quality and resilience to different biotic and abiotic stresses in citrus. Over- or under-fertilization can cause a serious reduction in yield, increase susceptibility to freeze damage and degrade soil health.” The article shared the following recommendations on soil sampling for a good fertilization program:
- “Soil samples should be taken at least once per year, preferably before a new fertilization cycle begins, typically in late fall or early spring.
- For newly established orchards, soil testing should be done before planting to make informed decisions on fertilizer applications.
- Divide the block into sampling areas that are uniform in soil type, management history or crop performance.
- Collect soil 8 to 10 inches deep using a soil probe or auger.
- Take soil from five different points for each sample.
- Mix the samples thoroughly in a clean bucket and fill a labeled soil sample bag with about 1 pint of soil.
- Send samples to the laboratory for analysis.”
The article also shared that “The other key to building a good citrus fertilization program…is leaf analysis,” and that “The most effective use of soil and leaf analysis is together.” See our blog on leaf tissue analysis!
